Critical Thinking and Decision-Making: What is Critical Thinking?

Lesson 1: what is critical thinking, what is critical thinking.

Critical thinking is a term that gets thrown around a lot. You've probably heard it used often throughout the years whether it was in school, at work, or in everyday conversation. But when you stop to think about it, what exactly is critical thinking and how do you do it ?

Watch the video below to learn more about critical thinking.

Simply put, critical thinking is the act of deliberately analyzing information so that you can make better judgements and decisions . It involves using things like logic, reasoning, and creativity, to draw conclusions and generally understand things better.

This may sound like a pretty broad definition, and that's because critical thinking is a broad skill that can be applied to so many different situations. You can use it to prepare for a job interview, manage your time better, make decisions about purchasing things, and so much more.

The process

As humans, we are constantly thinking . It's something we can't turn off. But not all of it is critical thinking. No one thinks critically 100% of the time... that would be pretty exhausting! Instead, it's an intentional process , something that we consciously use when we're presented with difficult problems or important decisions.

Improving your critical thinking

In order to become a better critical thinker, it's important to ask questions when you're presented with a problem or decision, before jumping to any conclusions. You can start with simple ones like What do I currently know? and How do I know this? These can help to give you a better idea of what you're working with and, in some cases, simplify more complex issues.  

Real-world applications

Let's take a look at how we can use critical thinking to evaluate online information . Say a friend of yours posts a news article on social media and you're drawn to its headline. If you were to use your everyday automatic thinking, you might accept it as fact and move on. But if you were thinking critically, you would first analyze the available information and ask some questions :

• What's the source of this article?
• Is the headline potentially misleading?
• What are my friend's general beliefs?
• Do their beliefs inform why they might have shared this?

After analyzing all of this information, you can draw a conclusion about whether or not you think the article is trustworthy.

Critical thinking has a wide range of real-world applications . It can help you to make better decisions, become more hireable, and generally better understand the world around you.

Critical Thinking

Developing the right mindset and skills.

By the Mind Tools Content Team

We make hundreds of decisions every day and, whether we realize it or not, we're all critical thinkers.

We use critical thinking each time we weigh up our options, prioritize our responsibilities, or think about the likely effects of our actions. It's a crucial skill that helps us to cut out misinformation and make wise decisions. The trouble is, we're not always very good at it!

In this article, we'll explore the key skills that you need to develop your critical thinking skills, and how to adopt a critical thinking mindset, so that you can make well-informed decisions.

What Is Critical Thinking?

Critical thinking is the discipline of rigorously and skillfully using information, experience, observation, and reasoning to guide your decisions, actions, and beliefs. You'll need to actively question every step of your thinking process to do it well.

Collecting, analyzing and evaluating information is an important skill in life, and a highly valued asset in the workplace. People who score highly in critical thinking assessments are also rated by their managers as having good problem-solving skills, creativity, strong decision-making skills, and good overall performance. [1]

Key Critical Thinking Skills

Critical thinkers possess a set of key characteristics which help them to question information and their own thinking. Focus on the following areas to develop your critical thinking skills:

Being willing and able to explore alternative approaches and experimental ideas is crucial. Can you think through "what if" scenarios, create plausible options, and test out your theories? If not, you'll tend to write off ideas and options too soon, so you may miss the best answer to your situation.

To nurture your curiosity, stay up to date with facts and trends. You'll overlook important information if you allow yourself to become "blinkered," so always be open to new information.

But don't stop there! Look for opposing views or evidence to challenge your information, and seek clarification when things are unclear. This will help you to reassess your beliefs and make a well-informed decision later. Read our article, Opening Closed Minds , for more ways to stay receptive.

Logical Thinking

You must be skilled at reasoning and extending logic to come up with plausible options or outcomes.

It's also important to emphasize logic over emotion. Emotion can be motivating but it can also lead you to take hasty and unwise action, so control your emotions and be cautious in your judgments. Know when a conclusion is "fact" and when it is not. "Could-be-true" conclusions are based on assumptions and must be tested further. Read our article, Logical Fallacies , for help with this.

Use creative problem solving to balance cold logic. By thinking outside of the box you can identify new possible outcomes by using pieces of information that you already have.

Self-Awareness

Many of the decisions we make in life are subtly informed by our values and beliefs. These influences are called cognitive biases and it can be difficult to identify them in ourselves because they're often subconscious.

Practicing self-awareness will allow you to reflect on the beliefs you have and the choices you make. You'll then be better equipped to challenge your own thinking and make improved, unbiased decisions.

One particularly useful tool for critical thinking is the Ladder of Inference . It allows you to test and validate your thinking process, rather than jumping to poorly supported conclusions.

Developing a Critical Thinking Mindset

Combine the above skills with the right mindset so that you can make better decisions and adopt more effective courses of action. You can develop your critical thinking mindset by following this process:

Gather Information

First, collect data, opinions and facts on the issue that you need to solve. Draw on what you already know, and turn to new sources of information to help inform your understanding. Consider what gaps there are in your knowledge and seek to fill them. And look for information that challenges your assumptions and beliefs.

Be sure to verify the authority and authenticity of your sources. Not everything you read is true! Use this checklist to ensure that your information is valid:

• Are your information sources trustworthy ? (For example, well-respected authors, trusted colleagues or peers, recognized industry publications, websites, blogs, etc.)
• Is the information you have gathered up to date ?
• Has the information received any direct criticism ?
• Does the information have any errors or inaccuracies ?
• Is there any evidence to support or corroborate the information you have gathered?
• Is the information you have gathered subjective or biased in any way? (For example, is it based on opinion, rather than fact? Is any of the information you have gathered designed to promote a particular service or organization?)

If any information appears to be irrelevant or invalid, don't include it in your decision making. But don't omit information just because you disagree with it, or your final decision will be flawed and bias.

Now observe the information you have gathered, and interpret it. What are the key findings and main takeaways? What does the evidence point to? Start to build one or two possible arguments based on what you have found.

You'll need to look for the details within the mass of information, so use your powers of observation to identify any patterns or similarities. You can then analyze and extend these trends to make sensible predictions about the future.

To help you to sift through the multiple ideas and theories, it can be useful to group and order items according to their characteristics. From here, you can compare and contrast the different items. And once you've determined how similar or different things are from one another, Paired Comparison Analysis can help you to analyze them.

The final step involves challenging the information and rationalizing its arguments.

Apply the laws of reason (induction, deduction, analogy) to judge an argument and determine its merits. To do this, it's essential that you can determine the significance and validity of an argument to put it in the correct perspective. Take a look at our article, Rational Thinking , for more information about how to do this.

Once you have considered all of the arguments and options rationally, you can finally make an informed decision.

Afterward, take time to reflect on what you have learned and what you found challenging. Step back from the detail of your decision or problem, and look at the bigger picture. Record what you've learned from your observations and experience.

Critical thinking involves rigorously and skilfully using information, experience, observation, and reasoning to guide your decisions, actions and beliefs. It's a useful skill in the workplace and in life.

You'll need to be curious and creative to explore alternative possibilities, but rational to apply logic, and self-aware to identify when your beliefs could affect your decisions or actions.

You can demonstrate a high level of critical thinking by validating your information, analyzing its meaning, and finally evaluating the argument.

Critical Thinking Definition, Skills, and Examples

• Homework Help
• Private School
• College Admissions
• College Life
• Graduate School
• Business School
• Distance Learning

• Indiana University, Bloomington
• State University of New York at Oneonta

Critical thinking refers to the ability to analyze information objectively and make a reasoned judgment. It involves the evaluation of sources, such as data, facts, observable phenomena, and research findings.

Good critical thinkers can draw reasonable conclusions from a set of information, and discriminate between useful and less useful details to solve problems or make decisions. These skills are especially helpful at school and in the workplace, where employers prioritize the ability to think critically. Find out why and see how you can demonstrate that you have this ability.

Examples of Critical Thinking

The circumstances that demand critical thinking vary from industry to industry. Some examples include:

• A triage nurse analyzes the cases at hand and decides the order by which the patients should be treated.
• A plumber evaluates the materials that would best suit a particular job.
• An attorney reviews the evidence and devises a strategy to win a case or to decide whether to settle out of court.
• A manager analyzes customer feedback forms and uses this information to develop a customer service training session for employees.

Why Do Employers Value Critical Thinking Skills?

Employers want job candidates who can evaluate a situation using logical thought and offer the best solution.

Someone with critical thinking skills can be trusted to make decisions independently, and will not need constant handholding.

Hiring a critical thinker means that micromanaging won't be required. Critical thinking abilities are among the most sought-after skills in almost every industry and workplace. You can demonstrate critical thinking by using related keywords in your resume and cover letter and during your interview.

How to Demonstrate Critical Thinking in a Job Search

If critical thinking is a key phrase in the job listings you are applying for, be sure to emphasize your critical thinking skills throughout your job search.

Add Keywords to Your Resume

You can use critical thinking keywords (analytical, problem solving, creativity, etc.) in your resume. When describing your work history, include top critical thinking skills that accurately describe you. You can also include them in your resume summary, if you have one.

For example, your summary might read, “Marketing Associate with five years of experience in project management. Skilled in conducting thorough market research and competitor analysis to assess market trends and client needs, and to develop appropriate acquisition tactics.”

Mention Skills in Your Cover Letter

Include these critical thinking skills in your cover letter. In the body of your letter, mention one or two of these skills, and give specific examples of times when you have demonstrated them at work. Think about times when you had to analyze or evaluate materials to solve a problem.

Show the Interviewer Your Skills

You can use these skill words in an interview. Discuss a time when you were faced with a particular problem or challenge at work and explain how you applied critical thinking to solve it.

Some interviewers will give you a hypothetical scenario or problem, and ask you to use critical thinking skills to solve it. In this case, explain your thought process thoroughly to the interviewer. He or she is typically more focused on how you arrive at your solution rather than the solution itself. The interviewer wants to see you analyze and evaluate (key parts of critical thinking) the given scenario or problem.

Of course, each job will require different skills and experiences, so make sure you read the job description carefully and focus on the skills listed by the employer.

Top Critical Thinking Skills

Keep these in-demand skills in mind as you refine your critical thinking practice —whether for work or school.

Part of critical thinking is the ability to carefully examine something, whether it is a problem, a set of data, or a text. People with analytical skills can examine information, understand what it means, and properly explain to others the implications of that information.

• Asking Thoughtful Questions
• Data Analysis
• Interpretation
• Questioning Evidence
• Recognizing Patterns

Communication

Often, you will need to share your conclusions with your employers or with a group of classmates or colleagues. You need to be able to communicate with others to share your ideas effectively. You might also need to engage in critical thinking in a group. In this case, you will need to work with others and communicate effectively to figure out solutions to complex problems.

• Active Listening
• Collaboration
• Explanation
• Interpersonal
• Presentation
• Verbal Communication
• Written Communication

Critical thinking often involves creativity and innovation. You might need to spot patterns in the information you are looking at or come up with a solution that no one else has thought of before. All of this involves a creative eye that can take a different approach from all other approaches.

• Flexibility
• Conceptualization
• Imagination
• Drawing Connections
• Synthesizing

Open-Mindedness

To think critically, you need to be able to put aside any assumptions or judgments and merely analyze the information you receive. You need to be objective, evaluating ideas without bias.

• Objectivity
• Observation

Problem-Solving

Problem-solving is another critical thinking skill that involves analyzing a problem, generating and implementing a solution, and assessing the success of the plan. Employers don’t simply want employees who can think about information critically. They also need to be able to come up with practical solutions.

• Attention to Detail
• Clarification
• Decision Making
• Groundedness
• Identifying Patterns

More Critical Thinking Skills

• Inductive Reasoning
• Deductive Reasoning
• Noticing Outliers
• Adaptability
• Emotional Intelligence
• Brainstorming
• Optimization
• Restructuring
• Integration
• Strategic Planning
• Project Management
• Ongoing Improvement
• Causal Relationships
• Case Analysis
• Diagnostics
• SWOT Analysis
• Business Intelligence
• Quantitative Data Management
• Qualitative Data Management
• Risk Management
• Scientific Method
• Consumer Behavior

Key Takeaways

• Demonstrate you have critical thinking skills by adding relevant keywords to your resume.
• Mention pertinent critical thinking skills in your cover letter, too, and include an example of a time when you demonstrated them at work.
• Finally, highlight critical thinking skills during your interview. For instance, you might discuss a time when you were faced with a challenge at work and explain how you applied critical thinking skills to solve it.

Defining Critical Thinking

The Peak Performance Center

The pursuit of performance excellence, critical thinking.

Critical thinking refers to the process of actively analyzing, assessing, synthesizing, evaluating and reflecting on information gathered from observation, experience, or communication. It is thinking in a clear, logical, reasoned, and reflective manner to solve problems or make decisions. Basically, critical thinking is taking a hard look at something to understand what it really means.

Critical Thinkers

Critical thinkers do not simply accept all ideas, theories, and conclusions as facts. They have a mindset of questioning ideas and conclusions. They make reasoned judgments that are logical and well thought out by assessing the evidence that supports a specific theory or conclusion.

When presented with a new piece of new information, critical thinkers may ask questions such as;

“What information supports that?”

“How was this information obtained?”

“Who obtained the information?”

“How do we know the information is valid?”

“Why is it that way?”

“What makes it do that?”

“How do we know that?”

“Are there other possibilities?”

Combination of Analytical and Creative Thinking

Many people perceive critical thinking just as analytical thinking. However, critical thinking incorporates both analytical thinking and creative thinking. Critical thinking does involve breaking down information into parts and analyzing the parts in a logical, step-by-step manner. However, it also involves challenging consensus to formulate new creative ideas and generate innovative solutions. It is critical thinking that helps to evaluate and improve your creative ideas.

Elements of Critical Thinking

Critical thinking involves:

• Gathering relevant information
• Evaluating information
• Asking questions
• Assessing bias or unsubstantiated assumptions
• Making inferences from the information and filling in gaps
• Using abstract ideas to interpret information
• Formulating ideas
• Weighing opinions
• Reaching well-reasoned conclusions
• Considering alternative possibilities
• Testing conclusions
• Verifying if evidence/argument support the conclusions

Developing Critical Thinking Skills

Critical thinking is considered a higher order thinking skills, such as analysis, synthesis, deduction, inference, reason, and evaluation. In order to demonstrate critical thinking, you would need to develop skills in;

Interpreting : understanding the significance or meaning of information

Analyzing : breaking information down into its parts

Connecting : making connections between related items or pieces of information.

Integrating : connecting and combining information to better understand the relationship between the information.

Evaluating : judging the value, credibility, or strength of something

Reasoning : creating an argument through logical steps

Deducing : forming a logical opinion about something based on the information or evidence that is available

Inferring : figuring something out through reasoning based on assumptions and ideas

Generating : producing new information, ideas, products, or ways of viewing things.

What is critical thinking?

5 characteristics of critical thinking, what are critical thinking skills, and why are they important, 6 key critical thinking skills, critical thinking example in real-life, 13 ways to start thinking critically.

Whether you’re aiming to improve your performance at work or simply trying to live a more fulfilling life , you’ll need a variety of hard and soft skills to move the needle. Some skills come naturally to some people, while others need to develop them actively.

One of these skills is critical thinking. But critical thinking itself is made up of several types of skills that contribute to solving problems more effectively.

Let’s explore the different types of critical thinking skills and how you can start improving them to level up your career.

Critical thinking is the ability to analyze facts objectively and form a judgment. It is a form of emotional intelligence .

Someone with critical thinking skills can think clearly and rationally when the situation demands it. It allows them to perform problem-solving and decision-making more effectively. 

As a result, you can look further than what you see at face value. You’re able to analyze what you see from a situation and gain some insight that goes further than what’s obvious to anyone from the outside.

Critical thinking also requires being able to understand the logical connection between two or more ideas or concepts. For example, a team working on a company’s pricing strategy needs to think critically about several concepts. 

Both the marketing and sales teams must work together. They need to analyze how to maximize sales. But they need to do so while also meeting profit goals. It’s important to understand the logical connection between sales strategy and marketing logistics. It’s the only way to get a good outcome.

Critical thinking is different from creative thinking . Creative thinking is the ability to generate brand new, innovative ideas. On the other hand, critical thinking requires you to carefully and logically analyze what information is given to you. Both are important to maximize results in any given situation.

What defines critical thinking? How does it affect the decision-making process? Here are five characteristics that make up the ability to think critically.

1. Dispositions

Critical thinkers have specific traits that allow them to think the way they do. Some people are predisposed to these traits, while others need to develop them actively.

Some of these dispositions include:

• Open-mindedness
• Respecting evidence and reasoning
• Being able to consider different perspectives and points of view: in other words, having cognitive flexibility
• Not being stuck in one position
• Clarity and precision

2. Argument

Good critical thinkers need to make solid arguments. 

An argument is making a statement aided by supporting evidence. It’s important to use well thought-out arguments when you’re in a constructive conflict . When analyzing a situation critically, you’ll need to make several arguments in your own mind to come to a judgment. 

3. Reasoning

In addition to arguments, critical thinking also requires inferring conclusions. From the facts and arguments presented to you, you need to use reasoning skills to come to a logical conclusion. 

This conclusion will determine the best course of action to take.

4. Criteria

Critical thinking is sometimes a matter of discerning truth from fiction. Not all facts presented to you may have the same level of truth. Certain conditions need to be met for something to be considered believable, and a critical thinker needs to be able to understand that.

5. Metacognition

Metacognition is the ability to think about your own thinking. Critical thinkers should be able to analyze their thoughts so that they can judge whether or not they’ve thought everything through. This helps them come up with better hypotheses.

The critical thinking skills definition is: soft skills that help you in the critical thinking process. Developing these skills can improve your ability to think critically.

Critical thinking skills are considered one of many durable skills in the workplace . Many of these are soft skills that are also useful in other situations.

According to research by America Succeeds, critical thinking is in the top five most requested durable skills in job postings. Those top five durable skills get requested 2.6x more often than the top five hard skills. This goes to show that soft skills like critical thinking skills are in demand in the workplace.

Critical thinking skills are important for several reasons. These include helping you work independently and solve problems . Not all positions require ongoing critical thinking. But, those skills definitely matter to anyone who wants to uplevel their career. And even the most easygoing positions require at least some level of critical thinking skills.

For example, working as an accountant can be straightforward in most cases. But it may require critical thinking skills. For instance, what if certain expenses aren’t easily distributed in simple categories? Without critical thinking skills, an accountant will struggle to work independently and solve problems on their own.

Critical thinking abilities also matter in everyday life. Having a foundation for critical thinking can help you analyze several possible solutions for problems that pop up in the home. It can also help you:

• Analyze different viewpoints
• Come up with the best solution for complex problems
• Become a better learner

The key critical thinking skills are identifying biases, inference, research, identification, curiosity, and judging relevance.

Let’s explore these six critical thinking skills you should learn and why they’re so important to the critical thinking process.

1. Identifying biases

This critical thinking skill is necessary for metacognition, which is the fifth characteristic of critical thinking. It involves knowing when others have a cognitive bias and when you have one yourself.

Biases can influence how someone understands the facts presented to them. But when you’re aware of those biases, you can question yourself on those biases and consider other points of view.

Identifying biases is especially important for people who make hiring decisions. That’s because biases against groups of minorities can lead to inequalities in the workplace when not identified. 

For example, imagine a hiring manager comparing two resumes. Their gut feeling could guide them to discount one of the resumes due to a bias against the opposite gender. But let’s say this hiring manager realizes they have this bias. They can then question themselves on whether or not this bias is influencing their judgment. 

2. Inference

Inference is the ability to draw conclusions based on the information you have. Without inference, it can be difficult to take action once you’ve analyzed the facts presented to you. Processing information is key to coming up with a reasoned judgment.

For example, let’s go back to the accountant struggling to assign the correct category to a business expense. They can analyze other similar situations and infer the most logical category based on that information.

3. Research

Before you analyze facts and infer a conclusion, you need to find out what those facts are. Researching skills allow you to discover facts and figures to make an argument.

Not all situations will have the required information available to you. Researching skills are necessary to dig into a situation and gather the information you need to think critically.

Some situations don’t require further research. For example, a first responder who arrives on the scene of an automobile accident won’t perform further research. They’ll have to analyze what they see in front of them and decide which injuries are the most urgent to care for. 

On the other hand, someone performing a market analysis will need to research competitors and gather information before coming up with an opinion. 

4. Identification

Identification is different from inference and research. It involves being able to identify a problem but also what’s influencing that problem.

In short, identification is necessary for someone to realize that they need to think critically about something. Without proper identification skills, it will be difficult for someone to know when it’s time to analyze a situation. 

For example, let’s say you’re entering numbers in a spreadsheet. The numbers aren’t coming out as they usually do. Without identification skills, you could easily keep going without realizing there’s an issue. But when you identify what’s going on, you can see that something is broken in the spreadsheet’s formula.

Only once you identify the fact that the formula is broken can you start analyzing what’s going on to solve the issue.

5. Curiosity

Don’t be afraid to question everything and explore what you’re curious about. That’s because intellectual curiosity is a valuable skill, especially when it comes to critical thinking.

One way to practice curiosity is to adopt a beginner’s mindset . When you come into every situation with the mindset of a beginner, you’re able to keep an open mind. You’ll be able to perceive things you may not have noticed when keeping your mind closed.

6. Judging relevance

Not all information is equally pertinent. In order to make a critical judgment, it’s important to be able to judge the relevance of the information you have.

Take, for instance, basic online researching skills. You have access to a plethora of information on virtually every topic imaginable. But performing online research requires you to constantly judge the relevance of what you see. 

Without judging relevance, you’d spend too much time on details that don’t matter as much for the final desired outcome. But when you’re able to discern what’s most pertinent, you can give that information more weight as you’re thinking critically.

So what would critical thinking skills look like in a real-life situation?

Let’s imagine you’re working in software quality assurance (QA) as a team lead. But every time your team needs to enter bug regression, everyone gets bottlenecked because you must manually populate the spreadsheet used for the regression. While you do this task, your team cannot be productive without you.

This process happens once a week and easily wastes half an hour for each team member.

First, you must identify what’s going on. The team gets bottlenecked because only you, as the team lead, can access the information required to fill in the regression spreadsheet.

Next, you can research information. You can inquire to higher-ups about the reason why only you have access to this information. You can also speak to other teams about what potential solutions they’ve come up with to solve this problem.

Once you’ve done your research, it’s time to analyze the information and judge relevance. Some teams have solutions that don’t apply to you, so that information isn’t relevant anymore. 

Figure out if there are any personal biases before you analyze your information. 

For example, it’s possible that you don’t get along with one of the other team leads. As a result, you could discount the information they’ve given you. But by identifying this bias, you can look past your personal opinion of this person and see how valuable their solution is.

Based on what you’ve analyzed, it’s time to brainstorm and come up with a solution. You realize that creating a simple, automated script will save your team’s time. And it will do so without consuming too many resources from the engineering department.

Next, present your solution to your manager. Explain how you came to this conclusion. 

Now, let’s say your spreadsheet automation solution is approved. It’s important to go back and analyze what happens after implementing the solution. But only do this once the spreadsheet has been in place for long enough to gather plenty of information. 

Here’s an example. You could realize that the solution did solve the bottleneck. But, the script also slows down the spreadsheet and makes it difficult to work with. This would require you to go back to the drawing board and start the process all over again.

A Guide To Critical Thinking think.maresh.info

What is Critical Thinking?

Critical thinking is the art of analyzing and evaluating thinking with a view to improving it in order to make an informed decision that is most likely to result in desired effects .

Critical thinking describes a process of uncovering and checking our assumptions and reasoning. First, we analyze to discover the assumptions that guide our decisions, actions, and choices. Next, we check the accuracy of these assumptions by exploring as many different perspectives, viewpoints, and sources as possible. Finally, we make informed decisions or judgments that are based on these researched assumptions.

Life is a series of decisions, some small, some much larger. Whom we date or choose as friends, the work or career we pursue, which political candidates we support, what we choose to eat, where we live, what consumer goods we buy, if and whom we marry, if and how we raise children—all these decisions are based on assumptions. We assume our friends will be trustworthy and won't talk about us behind our backs. We assume our career choices will be personally fulfilling or financially remunerative. We assume politicians we vote for have our, or the community's, best interests at heart. We assume that the foods we choose to eat are healthy for us, and so on.

These assumptions are sometimes correct. At other times, however, the assumptions we base our decisions on have never been examined. Sometimes we hold these assumptions because people we respect (friends, parents, teachers, religious leaders) have told us they are right. At other times we have picked these assumptions up as we travel through life but can't say exactly where they've come from. To make good decisions in life we need to be sure that these assumptions are accurate and valid – that they fit the situations and decisions we are facing. Critical thinking describes the process we use to uncover and check our assumptions. Decisions based on critical thinking are more likely to be ones we feel confident about and to have the effects we want them to have.

Your Mental Models

Mental models are the filters we use to understand the world. A mental model is a representation of how something works. Everyday we encounter so much information that we cannot store it all and the phenomena we encounter are too complex to understand every detail. Therefore, we use filtering models to simplify the complex into organizable and understandable chunks, conceptual models to file and organize new information, and reasoning models to create new ideas and make decisions.

Mental models shape what we think, how we interpret what we value most, where we direct our attention, how we reason, and where we perceive opportunities. The quality of our thinking is only as good as the models in our head and their usefulness in a given situation. The best models improve our likelihood of making the best decisions. By critically examining our assumptions, we can adjust them to be in better accord with reality and they become more powerful mental models in the toolkit through which we understand reality.

All of us go through life with many incorrect core assumptions about reality. For example, most of us believe (1) we are perceiving reality accurately, (2) our perceptions are valid, and (3) that what is obvious to us must be obvious to others. Let that sink in for a minute: these are incorrect assumptions. It is simply not possible to perceive reality accurately and everyone's reality is different. Our sensory nervous system sends gigabytes per minute of data to the brain but the brain has the attentional bandwidth to process megabytes per minute. On top of that, we are always allocating some of our bandwidth to our thoughts (have you every been lost in thought and missed an important detail?). To improve our thinking, first we have to accept that our perceptions of the moment are filtered through mental models , that our most dearly held beliefs may not correctly describe reality, and be open to improving them.

Building your toolkit of mental models is a lifelong project. Stick with it, and you'll find that your ability to understand reality, accomplish your goals, deepen your relationships, and make the best decisions will always improve. Critical thinking is a set of reasoning tools that we use to improve our other models about the world. They are the foundation upon which we can build our best mental models. In the next section, you will find an overview of the reasoning tools described in this website.

Organization of this Resource

Learn to analyze the elements of reasoning.

The Critical Analysis page is dedicated to the first step in the process of developing critical thinking skills, recognizing elements of reasoning that are present in the mind whenever we reason. I categorize six elements of reasoning: purposes, questions, points of view, information, assumptions, and reasoning. Note how these elements are related in the following paragraph.

To take command of our thinking, first we need to clearly formulate both our purpose and the question at issue. To uncover truths, we need to make logical inferences based on sound assumptions and information that is both accurate and relevant to the question we are dealing with. We need to understand our own point of view and fully consider other relevant viewpoints. We also need to recognize problems created by bugs in the human operating system by formally working around them. These bugs can be categorized into two major categories, each of which has it's own page.

Fallacies of reasoning are found in unsound arguments that may sound persuasive on the surface.

Cognitive biases are a predictably systematic patterns of deviation rationality in judgment. Cognitive biases can lead to irrational thought through distortions of perceived reality, inaccurate judgment, or illogical interpretation. For example, confirmation bias is the tendency to interpret new evidence as confirmation of one's existing beliefs and filter-out information that does not confirm one's existing beliefs.

Learn to evaluate reasoning

The Critical Evaluation page describes the second step in the process of critical thinking, evaluating the quality of thought. We need to use concepts justifiably and follow out the implications of decisions we are considering.

Learn to avoid other common mistakes

No one is a master of every discipline, however there are some common misconceptions that people have of other disciplines that you should learn to avoid.

Additionally, I have created a page of common writing errors that I have observed in developing student writing.

Before submitting your writing, I suggest that you please consult these resources as checklists and verify that you have done your best to avoid these mistakes.

Critical Analysis

Analysis is the act of breaking something complex down into simpler parts that you examine in detail. To critically analyze a text or idea, identify its purpose, the question at issue, the author's point of view, the kinds of information involved, the reasoning, and the conclusions.

Unless a text is simply presenting information, it will often contain arguments. An argument is a series of statements that reach a logical conclusion that is intended to reveal the degree of truth of another statement. Arguments begin with premises (kinds of information) that are related to each other using valid forms of reasoning (a process) to arrive at a logical conclusion, new information. A logical conclusion is a new kind of information that is true in light of premises being true (if the premises are all facts) or seeming to be true (if the premises contain some opinions). A logical conclusion may be false, if the premises are false or the reasoning is poor.

1. Identify the Purposes

All texts or ideas have a purpose .

• What do you think the author wants us to do, think about, or believe?
• Periodically check that the text or you are still on target with the purpose

2. Identify the Questions at Issue

When reasoning is present, the author is attempting to figure something out, to answer some question, or to solve a problem.

• Take time to clearly and precisely state the question at issue
• Express the question in several ways to clarify its meaning and scope
• Break down the question into sub questions
• Identify if the question has one right answer, is a matter of opinion, or requires reasoning from more than one point of view

3. Identify Points of View

All reasoning is done from some point of view. We often experience the world in such a way as to assume that we are observing things just as they are, as though we were seeing the world without the filter of a point of view. Nonetheless, we also recognize that others have points of view that lead them to conclusions we fundamentally disagree with. One of the key dispositions of critical thinking is the on-going sense that, as humans, we always think within a perspective, that we virtually never experience things totally and absolutely. There is a connection, therefore, between thinking so as to be aware of our assumptions and intellectual humility. Therefore, it is often helpful to open your mind and involve other people (friends, family, work colleagues) who help us see ourselves and our actions from unfamiliar perspectives. Sometimes reading books, watching videos, or having new experiences such as traveling to other cultures, going to college, or being an intern help us become aware of our assumptions. It is equally important to recognize that one person's is biased by their world view and experiences, and therefore all points of view should be examined critically.

• Identify your point of view
• Identify author's point of view
• Compare and contrast differing points of view

4. Distinguish Types of Information

Uncritical thinkers treat their conclusions as something given to them through experience, as something they directly observes in the world. As a result, they find it difficult to see why anyone might disagree with their conclusions. After all, they believe that the truth of their views is right there for everyone to see! Such people find it difficult to describe evidence without interpreting it through their point of view. Critical thinking requires the ability to label types of information and evaluate their quality before accepting an argument.

Information is true if it is accord accord with reality. Since our knowledge of reality is always incomplete, in practice truth is measured by its accord with the best information we have about reality. All information has an associated degree of belief (a feeling about truth) or confidence (the scientific term for statistical likelihood of truth) in its truth value. When analyzing, we are simply categorizing rather than evaluating the quality of the information.

All arguments are based on information. Premises are information that is used in the context of an argument. Information can be classified with four characteristics that describe the context in which it is used.

1. Evidence is information upon which conclusions are based. There are two categories of evidence:

• Facts (objective truth)
• Opinions (a feeling about the truth)

2. Assumptions are statements that we accept as true without proof or demonstration.

3. Conclusions are the results or reasoning, irrespective of their truth value.

4. Propaganda is information that is not objective and is used primarily to influence an audience and further an agenda

4A. Identify Evidence

Evidence is information that is relevant to question at issue. Both facts and opinions are evidence.

• Unless necessary facts unavailable, you should restrict your evidence to facts, verifiable information.
• Restrict your conclusions to those supported by the evidence you have.

A fact is an accurate description of an object, event, or statement that is independently verifiable by empirical means .

There are two distinct senses of the word "factual." The word may refer to a verified fact. However, "factual" may also refer to claims that are "factual in nature" in the sense that they can be verified or disproven by observation or empirical study, but those claims must be evaluated to determine if they are true. People often confuse these two senses, even to the point of accepting as true, statements which merely "seem factual", for example, "29.23 % of Americans suffer from depression." Before I accept this as true, I should assess it. I should ask such questions as "How do you know? How could this be known? Did you merely ask people if they were depressed and extrapolate those results? How exactly did you arrive at this figure?"

Purported facts should be assessed for their accuracy, completeness, and relevance to the issue. Sources of purported facts should be assessed for their qualifications, track records, and impartiality. Many students have experienced an education which stressed retention and repetition of factual claims. Such an emphasis stunts students' desire and ability to assess alleged facts, leaving them open to manipulation. Likewise, activities in which students "distinguish fact from opinion" often confuse these two senses. They encourage students to accept as true statements which merely "look like" facts.

To identify facts, look for these signal words in italics: "The annual report confirms ...," "Scientists have recently discovered ...," " According to the results of the tests...," "The investigation demonstrated ... "

Credible facts reference the observer of the information. You should accept a fact only after you have identified confirmation by many different independent observers and evaluated their credibility and potential bias. Even before this evaluation, you should reject a fact that does not have a clear source

As an example, in the debate we watched, Nick Gillespie says, "[drugs are] not addictive for 99 percent of people." This is factual only in the sense that may be empirically possible to measure, but you should not accept this as fact without more context such as a source.

If you have the opportunity, ask someone, "where did you get that information?" to give them the chance to confirm a fact. Until, you actually understand the limits and source of the fact, you should regard the information as suspicious and categorize it as an opinion that someone believes is true.

An opinion is a statement that expresses either how a person feels about something or what a person thinks is true . With objective verification, opinions can become facts. If they cannot be proven or disproven, they will always be opinions.

Since we cannot examine the facts in all situations, sometimes we must rely on an opinion as evidence in an argument. Any conclusion derived from an argument that uses an opinion in place of a fact will generally be less reliable. You should always acknowledge such uncertainty when presenting such a conclusion.

• Look for these signal words in italics: "He claimed that...," "It is the officer's view that...," "The report argues that...," "Many scientists suspect that... "
• Some opinions are more reliable than others. An opinion that is based on the objective consideration of a large amount of incomplete information will be more reliable than an opinion based on one observation and a feeling.
• Understand that things are not always as they appear to be. At times, writers, whether consciously or not, will frame opinion as fact and vice versa.
• Note that statements can contain both fact and opinion. They should be separately when analyzing an argument.

4B. Identify Assumptions

An assumption is a statement that we accept as true without proof or demonstration. It is an unstated premise, presupposition, or opinion that is required to connect data to conclusions.

All human thought and experience is based on assumptions. Our thought must begin with something we believe to be true in a particular context. We are typically unaware of what we assume and therefore rarely question our assumptions. Much of what is wrong with human thought can be found in the uncritical or unexamined assumptions that underlie it. Identifying and evaluating accuracy and validity of assumptions is arguably the most important application of critical thinking. Accurate and valid assumptions can become facts.

Assumptions are often very difficult to identify. Usually they are something we previously learned and do not question. They are part of our system of beliefs. We assume our beliefs to be true and use them to interpret the world about us.

This packet of exercises has many excellent examples assumptions identified in short scenarios.

4C. Identify Conclusions

Conclusions are the results or reasoning.

In logic, conclusions can be categorized based on their truth value:

• Sound conclusions result from true premises and valid reasoning.
• Unsound conclusions result from false premises and/or invalid reasoning.

Additionally, conclusions are often categorized as either:

• accurate/inaccurate based on the truth of the premises
• logical/illogical based on the quality of the reasoning
• justified/unjustified based on whether or not the truth value has been critically evaluated

Conclusions also can be categorized based on their role in an argument:

• Inferences (conclusions from a single step of reasoning that are used as a premise in a successive argument)
• Drawn conclusions (conclusions that relate back to the question at issue)

It should be noted that different disciplines that study human thought (i.e. philosophy, cognitive psychology, artificial intelligence, etc.) define the distinction between a conclusion and an inference differently. To avoid confusion, I will make the following distinctions. When analyzing reasoning, a logical conclusion refers to the result of any argument. When analyzing a complex argument focused on a question at issue, an inference is a logical conclusion drawn from a single step in reasoning and may be used as information in the premise of a successive step of reasoning. A drawn conclusion describes a logical conclusion that specifically answers the question at issue by logically relating many inferences as premises. The example in this article, effectively illustrates my distinction between an inference and drawn conclusion (Note that other sources may define these word in the exact opposite way!).

Conclusions are generally straight-forward to identify in context. When analyzing a complex argument focused on a complex question at issue, inferences are often made implicitly in the course of reasoning. For this reason, an inference may be more difficult to identify. Critical thinkers try to monitor their inferences to keep them in line with what is actually implied by what they know. When speaking, critical thinkers try to use words that imply only what they can legitimately justify. They recognize that there are established word usages which generate established implications.

• If we assume that it is dangerous to walk late at night in big cities and we move to Chicago, we will infer that it is dangerous to go for a walk late at night in Chicago. We probably take for granted our assumption that it is dangerous to walk late at night in big cities and in Chicago implicitly.
• To infer that an act that was murder, is to infer that it was intentional and unjustified. The implications of this inference are severe, thus sufficient evidence must exist to justify this opinion or fact.

A helpful tool is to first identify an inference (what do we infer from the situation being evaluated?) then identify an assumption that is the premise to that inference ("If the inference is true, what did I assume about the situation?"). Often an assumption you identify this way is an inference that can be further unpacked by repeating the second step to identify deeper core assumptions.

Situation: I heard a scratch at the door. I got up to let the cat in.

Inference: I inferred that the cat was at the door.

Ask: If that is true, what did I infer about the situation?

Assumptions: Only the cat makes that noise, and he makes it only when he wants to be let in.

Since different people can have difference assumptions, they will make different inferences about the reality of the same situation.

4D. Identify Propaganda

Propaganda is a special category of information that is not objective and is used primarily to influence an audience to reach a specific conclusion. Propaganda attempts to arouse emotions and biases to short-circuit rational judgment. The author of propaganda deliberately designs an argument that does not hold up to critical thinking. It's use indicates an intent to, at worst mislead, or at best persuade without the use of reasoning. Whether or not propaganda is ethical is a personal and context-dependent value judgment that is separate from critical thinking.

Students often find analysis of propaganda to be confusing because it is an extra feature of information, rather than its own type. Information that is propaganda can be any non-objective type (opinion, assumption, and/or inference) if it is deliberately used to manipulate opinions using poor reasoning. Moreover, propaganda quite utilizes poor reasoning—it often employs logical fallacies or takes advantage of cognitive biases to mislead.

The following is a list of common propaganda techniques:

• Bandwagon . It aims at persuading people to do a certain thing because many other people are doing it. An example can be a soft drink advertisement wherein a large group of people is shown drinking the same soft drink. People feel induced to opt for that drink as it is shown to be consumed by many. Similarly, by simply declaring without evidence that something is America's Favorite, significantly increases sales. Snob appeal is the reverse of bandwagon. It indicates that buying a certain product will make you stand out from the rest, as the masses won't afford to buy it.
• Card Stacking Propaganda. Now, this technique is perhaps most popularly used. It involves the deliberate omission of certain facts to fool the target audience. The term card stacking originates from gambling and occurs when players try to stack decks in their favor. A similar ideology is used by companies to make their products appear better than they actually are. Most brands use this propaganda technique to downplay unsavory details about their products and services. For instance, some companies may cleverly conceal "hidden charges" and only talk about the benefits of their products and services. Changing the shape of french fries so that one pays more for less food, still doesn't change the fact that eating fried food is unhealthy.
• Glittering Generalities Propaganda uses emotional appeal or/and vague statements to influence the audience. Advertising agencies thus use of phrases like as "inspiring you from within" or "to kick-start your day" to create positive anecdotes. This makes the product look more appealing, resulting in better sales.
• Hacking Identity: The Pride-Fear-Outrage-Hatred Formula. Critically examine when identity categories become significant to an argument. In some cases it may be appropriate, in others it may be an emotionally manipulative red herring.
• Example: In recent years, the Russian government has planted appeals to pride to amplify difference and strengthen online social communities. This is then followed by stories designed to invoke fear and outrage. A 2018 report to the United States Senate Select Committee on Intelligence details how these tactics are apparently designed to "hack" the minds of citizens in democratic nations into feeling disillusioned with social and political institutions. The goal is to weaken democratic participation and nudge countries towards increasingly pro-authoritarian values.
• Repetition. It is when the product name is repeated many times during an advertisement. This technique may use a jingle, which is appealing to the masses and fits in their minds. This takes advantage of the illusory truth effect, a cognitive bias that is encapsulated in the old adage, "if you tell a lie big enough and keep repeating it, people will eventually come to believe it." It is an unfortunate reality that the Internet is often used to make make untrue information seem true by repetition.
• Slogans. A slogan is a brief, striking phrase that may include labeling and stereotyping. Although slogans may be enlisted to support reasoned ideas, in practice they tend to act only as emotional appeals. Opponents of the US's invasion and occupation of Iraq use the slogan "blood for oil" to suggest that the invasion and its human losses was done to access Iraq's oil riches. On the other hand, supporters who argue that the US should continue to fight in Iraq use the slogan "cut and run" to suggest withdrawal is cowardly or weak. Similarly, the names of the military campaigns, such as "enduring freedom" or "just cause" can also be considered slogans, devised to influence people.
• Testimonial propaganda is popular advertising technique that uses renowned or celebrity figures to endorse products and services. Now in this case, when a famous person vouches for something, viewers are likely to take account of the credibility and popularity of that person. Watch Drake's Sprite commercial as an example.

Wikipedia has an extensive list of propaganda techniques with numerous examples.

5. Analyze Reasoning

The identification of poor reasoning invalidates the conclusion of an argument. The conclusion of the argument may or may not be true. You must formulate an alternative valid argue ment to support the conclusion.

5A. Identify Logical Fallacies

Fallacies are faulty reasoning used in the construction of an argument. This topic is so vast that I have created a separate fallacies of reasoning page.

5B. Identify Cognitive Biases

A cognitive bias is a cognitive shortcut that leads to a loss of objectivity. Cognitive biases can lead to irrational thought through distortions of perceived reality, inaccurate judgment, or illogical interpretation. By learning about some of the most common biases, you can learn and how to avoid falling victim to them.

The identification of cognitive biases at work in an argument should make you skeptical. Like fallacies, this topic is so vast that I have created a separate cognitive biases page to explain them.

Critical Evaluation

After we have cataloged the elements of reasoning, we must evaluate texts and our own reasoning for clarity, accuracy, precision, relevance, depth, breadth, significance, logic, and fairness. When making a decision with incomplete information, it is critical to recognize that truth is often a degree of belief based on our evaluation of the quality of the information and reasoning .

1. Evaluate point of view

• Playing the devil's advocate by arguing from a different point of view is a powerful exercise
• After reading a text, examine how much influence the author's point of view had on you

 Critically evaluate the reliability of an author (and publisher):

• What qualifications does the author have for writing on this subject? (Or what are the qualifications of the people the author quotes?)
• Based on your research on the author's background, what factors may have influenced his or her point of view?
• When and where was the article first published? Does this information affect the credibility of the article?

  Compare and contrast points of view to reveal how related material is presented by different authors and different purposes of their writing. After reading two texts on the same topic, ask yourself:

• What is the author's point of view in each of these articles?
• Why do you think that the points of view presented are so different?
• How much influence did each author's point of view have on you?

1A. Evaluate a Scientific Author's Qualifications

• Examine the primary source of information . ls there a reference to the source of information? If not, it cannot be verified. If so, is the source reputable?
• Examine the reputation of the author . Do the author(s) have training in science? If so, have they had formal training leading to an advanced degree such as a Master's degree or doctorate, and have they published widely in reputable journals? If not, then are they working with a reputable scientist(s) to evaluate the data?
• Does the discoverer say that a powerful establishment is trying to suppress his or her work? Often, the discoverer describes mainstream science as part of a larger conspiracy that includes industry and government. The idea is that the establishment will presumably stop at nothing to suppress discoveries that might shift the balance of wealth and power in society. This is not how science actually works. Science is an open and international enterprise focused on uncovering true descriptions of reality.
• Determine if the work was published in a peer-reviewed journal . Peer review is the standard process for scientific publications. Peer-reviewed manuscripts have been read by several scholars in the same field (called peers), and these peers have indicated that the experiments and conclusions meets the standards of their discipline and are suitable for publication. In the absence of peer-review the significance and quality of the data cannot be assessed.
• Has the discovery been pitched directly to the media? The integrity of science rests on the willingness of scientists to expose new ideas and findings to the scrutiny of other scientists. Thus, scientists expect their colleagues to reveal new findings to them initially. An attempt to bypass peer review by taking a new result directly to the media, and thence to the public, suggests that the work is unlikely to stand up to close examination by other scientists.
• Check if the journal has a good reputation for scientific research . If a peer-reviewed paper is cited, where was it published? Is the journal widely respected? One tool that is commonly used for ranking, evaluating, categorizing, and comparing journals is the frequency with which the "average article" in a journal has been cited in a particular year or period. The frequency of citation reflects acknowledgment of importance by the scientific community. High-impact and widely respected journals include Science and Nature. Therefore, a citation in Science generally suggests scholarly acceptance, whereas publication in a nonscientific or little-known journal does not.
• Determine if there is an independent confirmation by another published study . Even if a study is peer-reviewed and published in a reputable journal, independent assessment is critical to confirm or extend the findings. Even the best journals or scientists will occasionally make mistakes and publish papers that are later retracted. Sometimes there may be outright fabrication that is overlooked by the reviewers and not detected until later. In other cases, the scientific report may be accurate but its significance may be misrepresented by the media. Although it is a slow process ro establish a scientific "truth," a particular scientific conclusion will eventually either gain broad acceptance or be discarded.
• Assess whether a potential conflict of interest exists . Most of the high-impact journals require a conflict of interest statment on the first page of an article.
• Assess the quality of institution or panel . Does the report emanate from a University accredited by the U.S. Department of Education or equivalent society? Such information is generally more reliable than that issued from a single individual putting information out on the web. In the United States, government research arms such as the National Science Foundation and the National Institute of Health and professional scientific societies generally provide up-to-date, high-quality information.

2. Evaluate of Degree of Truth in Information

After analyzing to identify the different kinds of information, we must be explicit about the quality of each piece of information used in the text or our own thinking. Using the highest quality information in arguments increases the degree of belief in the truth of the argument. We must acknowledge when poor quality information is used in an argument and clearly state that we have low confidence in the truth of the argument.

• Search for information that opposes your position as well as information that supports it
• Make sure that all information used is clear, accurate, and relevant to the question at issue
• Make sure you have gathered sufficient information
• We can have the most confidence in facts that have been confirmed by many different independent observers.

A scientist's perspective on facts

In everyday language most of us consider a confirmed fact to be truth. However, scientists consider all truth to be provisional, the current facts serve as description of truth only for the time being. Scientists assume that all knowledge has the potential to be overturned if new information suggests that it should be. Scientists use the uncertainty and percent confidence to describe the statistical likelihood that a fact is true.

Physicist Richard P. Feynman once said, "In physics and in human affairs... whatever is not surrounded by uncertainty, cannot be the truth." He said this in reference to a newspaper article that asserted absolute belief in a scandalous rumor regarding a colleague. He observed that a responsible reporter should have referred to an "alleged incident." With no reference to a process that had first evaluated the quality of the truth, he considered accusation to be opinion, not fact.

• Is a particular measurement 78 ± 50 or 78 ± 1 meters? As you can see, the uncertainty deeply affects how you will use that information.
• It is a scientific formalism that any measurement missing a stated uncertainty has an uncertainty of ±1 in a last significant digit. Therefore, 78 seconds is understood to be 78 ± 1 seconds and 78.0 seconds is 78.0 ± 0.1 seconds.
• "The crash test results indicate a 98% chance that a head-on collision will kill you. As a professional scientist I cannot say that a head-on collision will kill you."

This last example highlight the property that all scientific information is actually a statement probability . Nothing in science is ever "proven" or "100% certain." Always avoid saying that science has proven something. This is a discipline-specific error in reasoning commonly made by non-scientists. Non-scientists sometimes misinterpret when scientists attach uncertainty to every fact. If there is 95% confidence that climate change is being caused by human activity, people with a psychological bias to avoid taking action around this crisis may focus on the 5% uncertainty in the truth value. On the other hand, people who are convinced of this fact and want to take action get frustrated that scientists refuse to say that it has been proven, we are certain. In practice, 95% confidence in science is the gold standard for a complex phenomenon being "as good as proven," but scientists always keep open the possibility that they don't have all the data and keep open the possibility that this fact may be more nuanced or simply wrong in the future.

Comparing and Contrasting Information

By comparing and contrasting information, you can identify facts, make inferences, and draw conclusions that would not otherwise be possible. After reading two texts, ask yourself:

• How do the articles differ in the information each one presents?
• Are the articles different in how they present information?
• Does the information appear to be complete and accurate? Why or why not?

2. Evaluate assumptions

[Unfinished]

Contrasting Assumptions

If two sides are arguing from different assumptions, it is very effective to focus on these in critical evaluation. Controversies generally rest on different sides interpreting the same information through different assumptions.

Assumptions, can be unjustified or justified, depending upon whether we do or do not have good reasons for them. Likewise, if two sides of a controversy share assumptions that are found faulty, both arguments become invalid.

• Ethan Nadelmann, founder and executive director of the Drug Policy Foundation, argues that law enforcement officials are overzealous in prosecuting individuals for marijuana possession citing that 87% of marijuana arrests are for possession of small amounts.
• The Office of National Drug Control Policy (ONDCP) contends that marijuana is not a harmless drug and must remain restricted. Besides causing physical problems, marijuana affects academic performance and emotional adjustment.
• Underlying both of their arguments is the assumption that adults cannot be permitted to make their own decisions about the use of particular drugs as they choose. A libertarian who worries about governmental restrictions on personal liberty would immediately recognize this shared deep assumption and challenge it. If convincingly challenged, both arguments lose validity.

3. Evaluate reasoning

When an argument doesn't "feel" right, first analyze it as follows. Write down the information that forms each premise of the argument and categorize them. Write down the conclusion and label it. Write your best general description of the reasoning that links them. The mechanics of the reasoning are usually found in a "therefore" type statement. To unmask the logic, replace the premise statements with letters that represent concepts and properties. Example: "It's raining and the sun is shining, therefore it's raining." The logical form is "X has property Q and P, therefore X has property Q". The logic is sound. [I will link some more examples later.]

3A. Logical Fallacies

Fallacies are faulty reasoning used in the construction of an argument. This topic is so vast that I have created a separate fallacies of reasoning page. The identification of fallacious reasoning invalidates an argument and we then forced to formulate our own arguments to uncover truth.

3B. Evaluate Propaganda

Propaganda is information that is not objective and is used primarily to influence an audience to reach a specific conclusion. Propaganda attempts to arouse emotions to short-circuit rational judgment. It is not by definition "good" or "bad." However, it's use indicates possible intent to, at worst mislead, or at best persuade without the use of reasoning. The techniques of propaganda are utilized in some logical fallacies and you will find some conceptual overlap. The following is a list of common propaganda techniques:

• Hacking Identity: The Pride, Fear, Outrage, Hatred Formula. Critically examine when identity categories become significant to an argument. In some cases it may be appropriate, in others it may be an emotionally manipulative red herring. Example: In recent years, the Russian government has planted appeals to pride to amplify difference and strengthen online social communities. This is then followed by stories designed to invoke fear and outrage. The effort is apparently designed to "hack" the minds of people in democratic nations into feeling disillusioned with social and political institutions.
• Stereotyping. People or objects are lumped together under simplistic labels, also called labeling. Example: Blonde women are beautiful, but dumb.
• Overgeneralizations . Treating a complex general thing as if it were a concrete thing. Example: " The UN's bureaucracy has forsaken its commitment... " or " The City extends strike deadline."

3C. Evaluate Cognitive Biases

A cognitive bias is a cognitive shortcut that leads to a loss of objectivity. Cognitive biases can lead to irrational thought through distortions of perceived reality, inaccurate judgment, or illogical interpretation. By learning about some of the most common biases, you can learn and how to avoid falling victim to them. The identification of cognitive biases at work in an argument should make you skeptical. Like fallacies, this topic is so vast that I have created a separate cognitive biases page to explain them.

4. Evaluate Judgments and Conclusions

After you read an article, you should be able to answer these questions:

• What judgments and conclusions were drawn by the author of this article?
• Are their faults of reasoning that make the drawn conclusion unjustified?
• Does the drawn conclusion challenge your assumptions?
• What other drawn conclusions are possible to draw using the same information?
• What other information might be important to know before making any judgment on the value and importance of this text?

5. Predict future Implications and Consequences

The alignment of reasonable future implications and consequences of a conclusion or judgment with your values should inform your reasoning.

• Trace the implications and consequences that follow from your reasoning
• Search for negative as well as positive implications
• Attempt to consider all possible consequences

Fallacies are faulty reasoning used in the construction of an argument . They make an argument appear to be better than it is. Here are some major fallacies of reasoning that you be able to recognize. All of the following fallacies are known as informal fallacies because they originate in a reasoning error. In contrast, formal fallacies , also known as non sequiturs, arise from the logical form of the argument. The following article introduces the most common fallacies.

In this video example we see rapid fire deployment of straw man, false dichotomy, and some formal fallacies on a kid who, impressively, recognizes each flaw of reasoning.

Identifying fallacies

Remember that arguments begin with premises that are related to each other using valid forms of reasoning to arrive at a logical conclusion .

Once you have analyzed the parts of an argument, evaluate:

Is the reasoning faulty?

• If the error in the argument is in the logical connection between two premises in drawing a conclusion it is likely to be a formal fallacy, also known as a non sequitur.
• If the truth revealed by the conclusion is a cause-effect relationship, it may be a questionable cause fallacy.
• Does the reasoning neglect many other possibilities? The argument might be a false dilemma or slippery slope fallacy.

Is/are the premise(s) faulty?

• If the premise of the argument must assume the conclusion to be true then read the section on improper premise fallacies.
• If weak premises and incomplete information lead to a strong conclusion, the argument contains a weak premise fallacy, also known as a faulty generalization.

Are the premises and/or the arguments a distraction from the actual issue in question?

• If any part of the argument is irrelevant to the actual issue, a relevance fallacy or red herring is at work.

Are you still not able to identify the error in reasoning?

• Consult the comprehensive list of fallacies at Wikipedia or ask your instructor for assistance.

Formal Fallacies (Non Sequiturs)

An error in the argument's form. Invalid logic is applied to the premises.

Fallacy fallacy. This is the inferrence that an argument containing a fallacy must have a false conclusion. It is entirely possible for someone to pose a bad argument for something that is true. Try not to get so caught-up in identification of logical fallacies that you are quick to dismiss a flawed argument—instead, try to make the argument reasonable.

• Example: "Some of your key evidence is missing, incomplete, or even faked! That proves I'm right!"

Syllogistic fallacies. There are many kinds of these. Syllogisms are generally three step arguments that use two premises to derive a conclusion. The premises and conclusion all take the form of categorical propositions that somehow relate two categories. These fallacies derive from incorrect application of logic. These fallacies are often more obvious if you draw a Venn diagram of the categories and shared features.

• Example: "All birds have beaks. That creature has a beak. Therefore, that creature is a bird."
• Form: All Z is B. This Y is B. Therefore, all Y is Z.
• Problem: B cannot be generalized as an exclusive feature of Z. Y could be an octopus.
• Example: "People in Kentucky support a border fence. People in New York do not support a border fence. Therefore, people in New York do not support people in Kentucky."
• Form: All Z is B. All Y is not B. Therefore, all Y is not Z.
• Problem: From the lack of shared B, nothing more can be logically implied about the features of either Z or Y. Z and Y may in fact agree on the desired outcomes for the question at issue but disagree over the means for achieving the outcomes.

Informal Fallacies

The proposed conclusion is not supported by the premises.

Whereas formal fallacies can be identified by form, informal fallacies are identified by examining the argument's content. There are many subcategories.

Improper Premise Fallacies

Any form of argument in which the conclusion occurs as one of the premises.

Begging the question. Providing what is essentially the conclusion of the argument as a premise. You assume without proof the stand/position that is in question. To "beg the question" is to put forward an argument whose validity requires that its own conclusion is true. Formally, begging the question statements are not structured as an argument and are harder to detect than circular arguments. Some authors consider circular reasoning to be a special case of begging the question. In the following examples, notice that the question at issue answers itself without argument.

• Example: "This whole abortion debate about when human life begins is ridiculous. We should be thinking about the rights of the baby."
• The question at issue: Should with examine when rights begin under the law? Premise: Rights begin after a baby is born. Conclusion: The debate is ridiculous.

Circular reasoning. Formally, circular reasoning differs from begging the question by specifically referring to arguments in which the reasoner simply repeats what they already assumed beforehand in different words without actually arriving at any new conclusion. Circular reasoning is not persuasive because a listener who doubts the conclusion will also doubt the premise that leads to it. This may sound silly, but people make such statements quite often when put under pressure.

• "Whatever is less dense than water will float, because such objects don't sink in water."
• "Of course smoking causes cancer. The smoke from cigarettes is a carcinogen."
• "The rights of the minority are every bit as sacred as the rights of the majority, for the majority's rights have no greater value than those of the minority."
• "Everyone wants the new iPhone because it is the hottest new gadget on the market!"
• Note that this could be factually true in the situation that popularity was the sole driver of consumer desire for the new iPhone. Even so, it is still a fallacy of circular reasoning because its popularity must be logically explainable for reasons other than the conclusion.
• Video example

Loaded question . Asking a question that has an assumption built into it so that it can't be answered without appearing guilty.

• Example: Prosecutor to defendant: "So how did you feel when you murdered your wife?"
• The question at issue: Did the suspect murder his wife? Premise: "you murdered your wife." Conclusion: "you murdered your wife." Possible responses: Any answer that the defendant gives to "how did you feel?" could construed as admission that he murdered his wife. The best response is to point-out the fallacy and refuse to answer the question as stated.

Weak Premise Fallacies

These reach a conclusion from weak premises. Unlike fallacies of relevance, the premises are related to the conclusions and yet only weakly support the conclusions. A faulty generalization is thus produced.

Cherry Picking / Card Stacking. The presentation of only that information or those arguments most favorable to a particular point of view.

• Example: "I'm a really good driver. In the past thirty years, I have gotten only four speeding tickets." (What other kind of tickets has he gotten? How long has he been driving?)

Faulty/Weak analogy. Comparison is carried too far, or the things compared have nothing in common.

• Example: Apples and oranges are both fruit. Both grow on trees. Therefore, apples and oranges taste the same.

Hasty Generalization (from an Unrepresentitve Sample). A judgment is made on the basis of inaccurate or insufficient evidence. They are extremely common because there is often no agreement about what constitutes sufficient evidence. Generalization from one person's experience is a common example of this fallacy.

• Example: "My grandfather smoked four packs of cigarettes a day since age fourteen and lived until age ninety-two. Therefore, smoking really can't be that bad for you."
• Example: "Ducks and geese migrate south for the winter. Therefore, all water-fowl migrate south for the winter."

No True Scotsman . Making what could be called an appeal to purity as a way to dismiss relevant criticisms or flaws of an argument.

• Example: Angus declares that Scotsmen do not put sugar on their porridge, to which Lachlan points out that he is a Scotsman and puts sugar on his porridge. Furious, like a true Scot, Angus yells that no true Scotsman sugars his porridge.

Questionable Cause Fallacies

The primary basis for these errors is either inappropriate deduction (or rejection) of causation or a broader failure to properly investigate the cause of an observed effect.

Correlation Without Causation / Cum Hoc. A faulty assumption that, because there is a correlation between two variables, one caused the other.

• Coincidence. The two variables aren't related at all, but correlate by chance.
• Third Cause. A third factor is the cause of the correlation. Example: Young children who sleep with the light on are much more likely to develop myopia in later life. Therefore, sleeping with the light on causes myopia. (In 1999, this was conclusion was popularized by the media from a study containing such a correlation. It is more likely that myopia has a genetic cause and myopic parents use nightlights because they have poor night vision without their glasses.)
• Wrong direction . Cause and effect are reversed. Example: The faster windmills are observed to rotate, the more wind is observed to be. Therefore wind is caused by the rotation of windmills. Real Life Example: When a country's debt rises above 90% of GDP, growth slows. Therefore, high debt causes slow growth.

Gamblers Fallacy. The incorrect belief that separate, independent events can affect the likelihood of another random event.

• Example: After having multiple children of the same sex, some parents may believe that they are due to have a child of the opposite sex. (In reality, the probability is still 0.5.)

False Cause / Post Hoc. Treating coincidence of one event following another as causation.

• Example: Every time we wash our car, it rains. Therefore, if we wash our car today, it will rain.
• Example: Specific vaccinations are given at the same age that obvious symptoms of autism typically manifest. When some parents see their children diagnosed with autism shortly after receiving vaccinations they assume that the vaccinations caused the autism (even though the autism could have been diagnosed by a professional

Single Cause Fallacy / Causal Oversimplification. It is assumed that there is one, simple cause of an outcome when in reality it may have been caused by a number of only jointly sufficient causes or a third cause.

• Example: The "Gateway Drug Theory" argues that marijuana usage leads to usage of harder drugs and has been a major justification for why marijuana laws should be highly restrictive. However, the same data could be explained by marijuana simply being easier to obtain and therefore more likely to be the first drug tried by people who were likely to become hard drug users for many other reasons such as genetic factors or simple illegality of marijuana making it attractive to risk-taking people.
• Example: Traffic fatalities were cut when the highway speed limit was reduced to 55 mph Therefore, the lower speed limit has resulted in safer highways. (The fact that people are driving less and seat belt laws were also passed may be equally or more important.)

Relevance Fallacies

These are distractions from the argument typically with some distracting sentiment that seems to be relevant but isn't really on-topic. Red Herrings are a specific sub-category Relevance fallacy that is distinguished by an intent to mislead often due the lack of a real argument.

Ad Hominem Argument . Rejection of a person's view on the basis of personal characteristics, background, physical appearance, or other features irrelevant to the argument at issue. Pay close attention to words that question an opponent's character. Examples: slob, prude, moron, embarrassing, stubborn.

Ambiguity . Using double meanings or other ambiguities of language to mislead or misrepresent the truth. Meaning in language can be so slippery that there are at least a dozen sub-fallacies including ambiguous grammar, equivocation, and quoting out of context (a tactic most often encountered on the Internet).

Appeal to Authority. This fallacy happens when we misuse an authority. This misuse of authority can occur in a number of ways. We can cite only authorities — steering conveniently away from other testable and concrete evidence as if expert opinion is always correct. Or we can cite irrelevant authorities, poor authorities, or false authorities.

Appeal to Emotion. The use of non-objective words, phrases, or expressions that arouse emotion having the effect of short-circuiting reason. Common examples include appeals to fear, flattery, outrage, pity, pride, ridicule of opponent's argument, spite, wishful thinking. Emotional appeals are also a powerful tool in propaganda.

• Example: A commercial for a security company that shows someone breaking into a home in the middle of the night.
• Example: "Any intelligent person knows... " (appeal to pride).

Appeal to Nature. Any argument that assumes "natural" things are "good" and "unnatural" things are "bad" is flawed because concepts of the natural, good, and bad are all vague and ambiguous. The person creating the argument can define these in any way that supports their position. Appeals to Nature also employ the begging the question fallacy (above).

• Example: This tobacco ad claims that their product is more natural and thus better for you.
• Example: This ad attempts to convince the reader that margarine, one the most processed foods in a grocery store, is natural and aligns with the readers assumed yearning for a simpler, better life in the country.
• The marketing copy for products in a store like Whole Foods is rife of appeals to Nature. Practice spotting them.

Argument from ignorance / burden of proof. It asserts that a proposition is true because it has not yet been proven false or a proposition is false because it has not yet been proven true. This type of argument asserts a truth and shifts the burden of providing counter-evidence onto someone else. Logically, we should remain skeptical and demand legitimate evidence from the person asserting the proposition.

• Example of two contradictory positions using this fallacy: "No one has ever been able to prove definitively that extra-terrestrials exist, so they must not be real." "No one has ever been able to prove definitively that extra-terrestrials do not exist, so they must be real."
• Video Example

Argument from incredulity (appeal to common sense) . Saying that because one finds something difficult to understand that it's therefore not true.

Association fallacy. Inferring either guilt or honor by association. It is an irrelevant attempt to transfer the qualities of one thing to another by merely invoking them together. Sometimes fallacies of this kind may also be appeals to emotion, hasty generalizations, and/or ad hominem arguments.

• Example: An attractive spokesperson will say that a specific product is good. The attractiveness of the spokesperson gives the product good associations.
• Example: "Galileo was ridiculed in his time but later acknowledged to be right. Likewise, Dr. Andrew Wakefield's work demonstrating that vaccines cause autism will later be recognized as correct too." (Taking an unpopular position is no guarantee of its correctness. Additionally, the two scenarios are not comparable. Galileo was ridiculed by the Catholic Church. His scientific peers generally confirmed his work. In contrast, Dr. Wakefield's scientific peers have failed to replicate his observations and have invalidate his conclusions based on methodological flaws. The source of negative public opinion around Dr. Wakefield derives from valid expert criticism.)

Bandwagon / FOMO. The use of the fear of being "different" or "missing-out" is used to influence behavior.

• Example: "Twenty million people jog for their health. Shouldn't you?

Genetic fallacy . Judging something good or bad on the basis of where it comes from, or from whom it comes.

• Example: "You're not going to wear a wedding ring, are you? Don't you know that the wedding ring originally symbolized ankle chains worn by women to prevent them from running away from their husbands? I would not have thought you would be a party to such a sexist practice." There are numerous motives explaining why people choose to wear wedding rings, but it would be a fallacy to presume those who continue the tradition are promoting sexism. (page 196 of ref)

Ignoring The Question. Digression, obfuscation, or similar techniques are used to avoid answering a question.

• Example: When asked about the possibility of a tax increase, a senator replies: "I have always met my obligations to those I represent."

Missing the point / Irrelevant Conclusion. Presenting an argument that may or may not be logically valid and sound, but whose conclusion fails to address the issue in question.

• Example: The Chewbacca Defense from South Park .

Straw Man Argument. Appearing to refute an opponent's argument by instead creating an oversimplified or extreme version of the argument (a "straw man") and refuting that instead.

Texas sharpshooter . A conclusion is drawn from data with a stress on similarities while ignoring differences. An example is seeing localized patterns where none exist. The name comes from a joke about a Texan who fires some gunshots at the side of a barn, then paints a target centered on the tightest cluster of hits and claims to be a sharpshooter.

Tu Quoque Fallacy. Latin for "you too," is also called the "appeal to hypocrisy" because it distracts from the argument by pointing out hypocrisy in the opponent. This tactic doesn't prove one's point, because even hypocrites can tell the truth.

Informal Fallacies with Multiple Structural Problems

Composition / Division . The fallacy of composition infers that something is true of the whole from the fact that it is true of a part of the whole. The opposite reasoning is the fallacy of division.

False dilemma / false dichotomy / black and white. Reducing an issue to only two possible decisions.

• Example: Either we go to war, or we appear weak.

Middle ground / false compromise / argument to moderation . Arguing that a compromise, or middle point, between two extremes is the truth.

• Example: Holly said that vaccinations caused autism in children, but her scientifically well-read friend Caleb said that this claim had been debunked and proven false. Their friend Alice offered a compromise that vaccinations cause some autism. (ref)

Slippery Slope. Moving from a seemingly benign premise or starting point and working through a number of small steps to an improbable extreme when many other outcomes could have been possible. Although this form of slippery slope is a sub-type of the formal appeal of probability fallacy (it assumes something will occur based on probability and thus breaks rules of formal logic), slippery slope arguments can take on many other forms and should are generally categorized as informal fallacies.

• Video examples: Don't Wake Up In A Roadside Ditch commercial and the children's book If You Give a Mouse a Cookie .

Special pleading . Moving the goalposts to create exceptions when a claim is shown to be false. Applying a double standard, generally to oneself.

"The first principle is that you must not fool yourself – and you are the easiest person to fool." –Richard Feynman

As we examine our assumptions and improve our mental models , we have to confront the reality that we all have inescapable hardwired biases that we cannot change through critical thinking. Because we all have them, science can teach us a lot about our biases. Biases are an inescapable feature of being human. No training will stop you from commiting them. However, learning about them can help you second guess the validity of your judgment, think more critically, consider other points-of-view, and develop empathy for the biases in others.

The operating system of our brains uses biologically evolved shortcuts in our thinking. Many of these shortcuts are useful and essential. However, we have also inherited bugs in the code that make many of our judgments irrational. A cognitive bias is a cognitive shortcut that leads to a loss of objectivity. By learning about some of the most common biases, you can learn and how to avoid falling victim to them. For example many of the biases below occur because the brain tends to find patterns where none exist and uses irrational biases to reduce cognitive dissonance when stressed with contradictory ideas. To learn more, I recommend reading Thinking Fast and Slow and You Are Not So Smart .

Common Cognitive Biases

Anchoring . The first thing you judge influences your judgment of all that follows.

Human minds are associative in nature, so the order in which we receive information helps determine the course of our judgments and perceptions. For instance, the first price offered for a used car sets an 'anchor' price which will influence how reasonable or unreasonable a counter-offer might seem. Even if we feel like an initial price is far too high, it can make a slightly less-than-reasonable offer seem entirely reasonable in contrast to the anchor price.

Be especially mindful of this bias during financial negotiations such as houses, cars, and salaries. The initial price offered has proven to have a significant effect.

Availability heuristic . Your judgments are influenced by what springs most easily to mind.

How recent, emotionally powerful, or unusual your memories are can make them seem more relevant. This, in turn, can cause you to apply them too readily. For instance, when we see news reports about homicides, child abductions, and other terrible crimes it can make us believe that these events are much more common and threatening to us than is actually the case.

Try to gain different perspectives and relevant statistical information rather than relying purely on first judgments and emotive influences.

Barnum effect . You see personal specifics in vague statements by filling in the gaps (e.g. interpreting your horoscope).

Because our minds are given to making connections, it's easy for us to take nebulous statements and find ways to interpret them so that they seem specific and personal. The combination of our egos wanting validation with our strong inclination to see patterns and connections means that when someone is telling us a story about ourselves, we look to find the signal and ignore all the noise.

Psychics, astrologers and others use this bias to make it seem like they're telling you something relevant. Consider how things might be interpreted to apply to anyone, not just you.

Belief bias . You are more likely to accept an argument that supports a conclusion that aligns with his values, beliefs and prior knowledge, while rejecting counter arguments to the conclusion.

It's difficult for us to set aside our existing beliefs to consider the true merits of an argument. In practice this means that our ideas become impervious to criticism, and are perpetually reinforced. Instead of thinking about our beliefs in terms of 'true or false' it's probably better to think of them in terms of probability. For example we might assign a 95%+ chance that thinking in terms of probability will help us think better, and a less than 1% chance that our existing beliefs have no room for any doubt. Thinking probabalistically forces us to evaluate more rationally.

A useful thing to ask is 'when and how did I get this belief?' We tend to automatically defend our ideas without ever really questioning them.

Belief perserverance . When some aspect of your core beliefs is challenged, it can cause you to believe even more strongly.

We can experience being wrong about some ideas as an attack upon our very selves, or our tribal identity. This can lead to motivated reasoning which causes a reinforcement of beliefs, despite disconfirming evidence. Recent research shows that the backfire effect certainly doesn't happen all the time. Most people will accept a correction relating to specific facts, however the backfire effect may reinforce a related or 'parent' belief as people attempt to reconcile a new narrative in their understanding.

"It ain't what you don't know that gets you into trouble. It's what you know for sure that just ain't so." —Mark Twain

Bystander effect . You presume someone else is going to do something in an emergency situation.

When something terrible is happening in a public setting we can experience a kind of shock and mental paralysis that distracts us from a sense of personal responsibility. The problem is that everyone can experience this sense of deindividuation in a crowd. This same sense of losing our sense of self in a crowd has been linked to violent and anti-social behaviors. Remaining self-aware requires some amount of effortful reflection in group situations.

If there's an emergency situation, presume to be the one who will help or call for help. Be the change you want to see in the world.

Confirmation bias . You favor things that confirm your existing beliefs.

We are primed to see and agree with ideas that fit our preconceptions, and to ignore and dismiss information that conflicts with them. You could say that this is the mother of all biases, as it affects so much of our thinking through motivated reasoning. To help counteract its influence we ought to presume ourselves wrong until proven right. "When you are studying any matter, or considering any philosophy, ask yourself only what are the facts and what is the truth that the facts bear out. Never let yourself be diverted either by what you wish to believe or by what you think would have beneficent social effects if it were believed." – Bertrand Russell

Think of your ideas and beliefs as software you're actively trying to find problems with rather than things to be defended.

Curse of knowledge . Once you understand something you presume it to be obvious to everyone.

Things makes sense once they make sense, so it can be hard to remember why they didn't. We build complex networks of understanding and forget how intricate the path to our available knowledge really is. This bias is closely related to the hindsight bias wherein you will tend to believe that an event was predictable all along once it has occurred. We have difficulty reconstructing our own prior mental states of confusion and ignorance once we have clear knowledge.

When teaching someone something new, go slow and explain like they're ten years old (without being patronizing). Repeat key points and facilitate active practice to help embed knowledge.

Declinism . You remember the past as better than it was, and expect the future to be worse than it will likely be.

Despite living in the most peaceful and prosperous time in history, many people believe things are getting worse. The 24 hour news cycle, with its reporting of overtly negative and violent events, may account for some of this effect. We can also look to the generally optimistic view of the future in the early 20th century as being shifted to a dystopian and apocalyptic expectation after the world wars, and during the cold war. The greatest tragedy of this bias may be that our collective expectation of decline may contribute to a real-world self-fulfilling prophecy. For some real data,

Instead of relying on nostalgic impressions of how great things used to be, use measurable metrics such as life expectancy, levels of crime and violence, and prosperity statistics.

Dunning-Kruger effect . The more you know, the less confident you're likely to be. The less you know, the more confident you are likely to be.

Because experts know just how much they don't know, they tend to underestimate their ability; but it's easy to be over-confident when you have only a simple idea of how things are. Try not to mistake the cautiousness of experts as a lack of understanding, nor to give much credence to lay-people who appear confident but have only superficial knowledge.

"The whole problem with the world is that fools and fanatics are so certain of themselves, yet wiser people so full of doubts." —Bertrand Russell

Framing effect . You allow yourself to be unduly influenced by context and delivery.

We all like to think that we think independently, but the truth is that all of us are, in fact, influenced by delivery, framing and subtle cues. This is why the ad industry is a thing, despite almost everyone believing they're not affected by advertising messages. The phrasing of how a question is posed, such as for a proposed law being voted on, has been shown to have a significant effect on the outcome.

Only when we have the intellectual humility to accept the fact that we can be manipulated, can we hope to limit how much we are. Try to be mindful of how things are being put to you.

Fundamental attribution error . You judge others on their character, but yourself on the situation.

If you haven't had a good night's sleep, you know why you're being a bit slow; but if you observe someone else being slow you don't have such knowledge and so you might presume them to just be a slow person. Because of this disparity in knowledge we often overemphasize the influence of circumstance for our own failings, as well as underestimating circumstantial factors to explain other people's problems.

It's not only kind to view others' situations with charity, it's more objective too. Be mindful to also err on the side of taking personal responsibility rather than justifying and blaming.

Groupthink . You let the social dynamics of a group situation override the best outcomes.

Dissent can be uncomfortable and dangerous to one's social standing, and so often the most confident or first voice will determine group decisions. Because of the Dunning-Kruger effect, the most confident voices are also often the most ignorant.

Rather than openly contradicting others, seek to facilitate objective means of evaluation and critical thinking practices as a group activity.

In-group bias . You unfairly favor those who belong to your group.

We presume that we're fair and impartial, but the truth is that we automatically favor those who are most like us, or belong to our groups. This blind tribalism has evolved to strengthen social cohesion, however in a modern and multicultural world it can have the opposite effect.

Try to imagine yourself in the position of those in out-groups; whilst also attempting to be dispassionate when judging those who belong to your in-groups.

Just world hypothesis . Your preference for justice makes you presume it exists.

A world in which people don't always get what they deserve, hard work doesn't always pay off, and injustice happens is an uncomfortable one that threatens our preferred narrative. However, it is also the reality. This bias is often manifest in ideas such as 'what goes around comes around' or an expectation of 'karmic balance', and can also lead to blaming victims of crime and circumstance.

A more just world requires understanding rather than blame. Remember that everyone has their own life story, we're all fallible, and bad things happen to good people.

Halo effect . How much you like someone, or how attractive they are, influences your other judgments of them.

Our judgments are associative and automatic, and so if we want to be objective we need to consciously control for irrelevant influences. This is especially important in a professional setting. Things like attractiveness can unduly influence issues as important as a jury deciding someone's guilt or innocence. If someone is successful or fails in one area, this can also unfairly color our expectations of them in another area.

If you notice that you're giving consistently high or low marks across the board, it's worth considering that your judgment may be suffering from the halo effect.

Negativity bias . You allow negative things to disproportionately influence your thinking.

The pain of loss and hurt are felt more keenly and persistently than the fleeting gratification of pleasant things. We are primed for survival, and our aversion to pain can distort our judgment for a modern world. In an evolutionary context it makes sense for us to be heavily biased to avoid threats, but because this bias affects our judgments in other ways it means we aren't giving enough weight to the positives.

Pro-and-con lists, as well as thinking in terms of probabilities, can help you evaluate things more objectively than relying on a cognitive impression.

Optimism bias . You overestimate the likelihood of positive outcomes.

There can be benefits to a positive attitude, but it's unwise to allow such an attitude to adversely affect our ability to make rational judgments (they're not mutually exclusive). Wishful thinking can be a tragic irony insofar as it can create more negative outcomes, such as in the case of problem gambling.

If you make rational, realistic judgments you'll have a lot more to feel positive about.

Pessimism bias . You overestimate the likelihood of negative outcomes.

Pessimism is often a defense mechanism against disappointment, or it can be the result of depression and anxiety disorders. Pessimists often justify their attitude by saying that they'll either be vindicated or pleasantly surprised, however a pessimistic attitude may also limit potential positive outcomes. It should also be noted that pessimism is something very different to skepticism: the latter is a rational approach that seeks to remain impartial, while the former is an expectation of bad outcomes.

Perhaps the worst aspect of pessimism is that even if something good happens, you'll probably feel pessimistic about it anyway.

Placebo effect . If you believe you're taking medicine it can sometimes 'work' even if it's fake.

The placebo effect can work for stuff that our mind influences (such as pain) but not so much for things like viruses or broken bones. Things like the size and color of pills can have an influence on how strong the effect is and may even result in real physiological outcomes. We can also falsely attribute getting better to an inert substance simply because our immune system has fought off an infection i.e. we would have recovered in the same amount of time anyway.

Homeopathy, acupuncture, and many other forms of natural 'medicine' have been proven to be no more effective than placebo. Keep a healthy body and bank balance by using evidence-based medicine from a qualified doctor.

Reactance . You'd rather do the opposite of what someone is trying to make you do.

When we feel our liberty is being constrained, our inclination is to resist, however in doing so we can over-compensate. While blind conformity is far from an ideal way to approach things, neither is being a knee-jerk contrarian.

Be careful not to lose objectivity when someone is being coercive/manipulative, or trying to force you do something. Wisdom springs from reflection, folly from reaction.

Self-serving bias . You believe your failures are due to external factors, yet you're responsible for your successes.

Many of us enjoy unearned privileges, luck and advantages that others do not. It's easy to tell ourselves that we deserve these things, whilst blaming circumstance when things don't go our way. Our desire to protect and exalt our own egos is a powerful force in our psychology. Fostering humility can help countermand this tendency, whilst also making us nicer humans.

When judging others, be mindful of how this bias interacts with the just-world hypothesis, fundamental attribution error, and the in-group bias.

Spotlight effect . You overestimate how much people notice how you look and act.

Most people are much more concerned about themselves than they are about you. Absent overt prejudices, people generally want to like and get along with you as it gives them validation too. It's healthy to remember that although we're the main character in the story of our own life, everyone else is center-stage in theirs too. This bias causes so many people to attribute to motives of malice when there may have been a simple misunderstanding.

Instead of worrying about how you're being judged, consider how you make others feel. They'll remember this much more, and you'll make the world a better place.

Sunk cost fallacy . You irrationally cling to things that have already cost you something.

When we've invested our time, money, or emotion into something, it hurts us to let it go. This aversion to pain can distort our better judgment and cause us to make unwise investments. A sunk cost means that we can't recover it, so it's rational to disregard the cost when evaluating. For instance, if you've spent money on a meal but you only feel like eating half of it, it's irrational to continue to stuff your face just because 'you've already paid for it'; especially considering the fact that you're wasting actual time doing so.

To regain objectivity, ask yourself: had I not already invested something, would I still do so now? What would I counsel a friend to do if they were in the same situation?

Discipline-specific misconceptions often made in arguments

• Everything is made of chemicals. Avoid saying that chemicals are "unnatural" or "dangerous."
• Medicine is not strictly a scientific profession. It can be, but is not required to be. A lot of what doctors actually do is non-scientific. The art of medicine is just as important as the science. For example, simply creating the feeling that the doctor understands a patient's problem and shares the patient's values increases the likelihood of positive health outcomes. Avoid the assumption that doctors are scientists.
• It can be just as dangerous to over-medicalize mental illness as it is to moralize about it. This is why recent writers like Johann Hari focus on non-medical aspects of addiction. From his popular TED Talk you might conclude that he dismisses the model that addiction is a physical medical condition. But if you read his book Chasing The Scream, you would learn that he actually accepts the medical model as part of a bigger picture, considers it mainstream in medicine, and has chosen to make a case for the significance of the social contributors to addiction. From Hari's point-of-view, the American medical system is incentivized to offer the lowest-cost quick fix (like a pill) so treating addiction as a solely medical condition can lead to oversimplified treatments that are less effective that complex, tailored treatments that consider an addict's social circumstances. His slogan, "the opposite of addiction is connection," is effective because it is memorable, however it is just as oversimplified as the purely medical model.

Neuroscience

• Everything alters the brain. Reading these words physically alters your brain by creating memories. In your writing, it is not enough to say the "repeated cocaine use alters the brain." Be specific about how the brain is altered and what the consequence is.
• Every human quality we care about has a dual nature . On one hand its character is limited by biology and the laws of physics. And on the other hand its experience is shaped by culture and personal experience. Thinkers who amplify the importance of biology in shaping behavior are making essentialist arguments. Thinkers who focus on the culturally constructed nature of a human quality are making constructivist arguments. It is important to study and understand the essential and constructed qualities of such concepts as gender, intelligence, athletic ability, extroversion, honesty, mental illness, etc. By separating "nature" from "nurture" we can learn how each contributes to the total phenomenon. But by taking either position, without acknowledging the role of the other, ignores the complexity of reality and leads to weak models. Avoid such overly simplifying models in your own thinking and question them in others.
• Avoid the words "prove," "proven," "proof," etc. Outside of mathematics, nothing is actually "proven" in life. Instead of writing, "It's been proven..." try "It's been observed..." or "Scientists have support for the theory..."

A longer list of misconceptions

Wikipedia has a great list of common misconceptions on many other topics.

Writing Tips

General style tips .

• For essays, refer to the MLA Writing guidelines.
• For scientific and technical writing, refer to the ACS Style Guide .

Citing and Referencing

• If you do not reference a fact in your writing, assume that a critical thinker will give it low likely hood of being true.
• When you quote someone, state their title and credentials. Give context to who they are to help your reader determine if the person being quoted is trustworthy and/or qualified.
• Cite the page number when citing a book.
• Avoid citing websites whenever possible. With the exception of a few online academic journals, assume that anything published online may be gone tomorrow and your reader will not be able to find it.
• A website is not a journal. Before citing a website, try to locate a print citation.
• Google is not a dictionary. If you cite a definition you got from Google, visit the "Google Dictionary" Wikipedia entry to discover who their current content provider is for definitions.
• Google is not a book publisher. Books you find in Google Books, were published somewhere else. Check the title page.

Presenting Information

• When you quote someone , always explain who they are. If they are an expert or researcher, state their qualifications and connect them to reputable organizations that sponsor their work. Doing this makes your writing more persuasive and makes it easier for your reader to research this person to come to their own conclusions.
• Example: "Michael Kuhar, an addiction researcher at the Emory University School of Medicine, explains that..."
• Give credit to the primary source of an idea , even if you encountered it in a secondary source. You should make an effort to read the primary source before quoting it's information and conclusion. If you are unable to, then be clear that you are repeating another author's interpretation of the primary source.

Glossary 

Why are precise definitions of concepts and ideas important.

Humans think within concepts or ideas. We can never achieve command over our thoughts unless we learn how to achieve command over our concepts or ideas. Thus we must learn how to identify the concepts or ideas we are using, contrast them with alternative concepts or ideas, and clarify what we include and exclude by means of them. For example, most people say they believe strongly in democracy, but few can clarify with examples what that word does and does not imply. Most people confuse the meaning of words with cultural associations, with the result that "democracy" means to people whatever we do in running our government—any country that is different is undemocratic. We must distinguish the concepts implicit in the English language from the psychological associations surrounding that concept in a given social group or culture. The failure to develop this ability is a major cause of uncritical thought and selfish critical thought.

• Consider alternative concepts
• Consider that others may be using alternative definitions of concepts
• Make sure you are using concepts with care and precision
• If you suspect a difference in definitions betwen you and another person, attempt to clarify each other's meaning

Fundamental Definitions

Argument. An argument is a series of statements that reach a conclusion that is intended to reveal the degree of truth of another statement. Arguments begin with premises (kinds of information) that are related to each other using valid forms of reasoning (a process) to arrive at the logical conclusion , new information. A logical conclusion is a new kind of information that is true in light of premises being true (if the premises are all facts) or seeming to be true (if the premises contain opinions).

Critical thinker. A well-cultivated critical thinker raises vital questions and problems, formulating them clearly and precisely; gathers and assesses relevant information, using abstract ideas to interpret it effectively; comes to well-reasoned conclusions and solutions, testing them against relevant criteria and standards; thinks open mindedly within alternative systems of thought, recognizing and assessing, as need be, their assumptions, implications, and practical consequences; is committed to overcoming our native confirmation bias, egocentrism, and sociocentrism; and communicates effectively with others in figuring out solutions to complex problems. ( https://www.criticalthinking.org )

Concept . A concept is a generalized idea of a thing or of a class of things that make up the fundamental building blocks of thoughts. Concepts are your brain's representations of past experiences (Barsalou 2003 and 2008). Using concepts, your brain groups some things together and separates others. You can look at three mounds of dirt and perceive two of them as "Hills" and one as a "Mountain," based on your concepts. The dominant psychological/philosophical school of thought known as constructivism assumes that the world like a sheet of pastry and your concepts are cookie cutters that carve boundaries, not because the boundaries are natural , but because they're useful or desirable . These boundaries have physical limitations of course; you'd never perceive a mountain as a lake (Boghossian 2006).

Empirical. Relying on or derived from experiment, observation, or experience as opposed to conceptual or evaluative.

Idea. An idea is anything existing in the mind as an object of knowledge or thought based on concepts regarding particular instances of a class of things. The word specifically refers to something conceived in the mind or imagined. An idea can be specific whereas concepts are generalized.

Thought refers to any idea, whether or not expressed, that occurs to the mind in reasoning or contemplation.

How to build critical thinking skills for better decision-making

It’s simple in theory, but tougher in practice – here are five tips to get you started.

Have you heard the riddle about two coins that equal thirty cents, but one of them is not a nickel? What about the one where a surgeon says they can’t operate on their own son?

Those brain teasers tap into your critical thinking skills. But your ability to think critically isn’t just helpful for solving those random puzzles – it plays a big role in your career. 

An impressive 81% of employers say critical thinking carries a lot of weight when they’re evaluating job candidates. It ranks as the top competency companies consider when hiring recent graduates (even ahead of communication ). Plus, once you’re hired, several studies show that critical thinking skills are highly correlated with better job performance.

So what exactly are critical thinking skills? And even more importantly, how do you build and improve them? 

What is critical thinking?

Critical thinking is the ability to evaluate facts and information, remain objective, and make a sound decision about how to move forward.

Does that sound like how you approach every decision or problem? Not so fast. Critical thinking seems simple in theory but is much tougher in practice, which helps explain why 65% of employers say their organization has a need for more critical thinking. 

In reality, critical thinking doesn’t come naturally to a lot of us. In order to do it well, you need to:

• Remain open-minded and inquisitive, rather than relying on assumptions or jumping to conclusions
• Ask questions and dig deep, rather than accepting information at face value
• Keep your own biases and perceptions in check to stay as objective as possible
• Rely on your emotional intelligence to fill in the blanks and gain a more well-rounded understanding of a situation

So, critical thinking isn’t just being intelligent or analytical. In many ways, it requires you to step outside of yourself, let go of your own preconceived notions, and approach a problem or situation with curiosity and fairness.

It’s a challenge, but it’s well worth it. Critical thinking skills will help you connect ideas, make reasonable decisions, and solve complex problems.

7 critical thinking skills to help you dig deeper

Critical thinking is often labeled as a skill itself (you’ll see it bulleted as a desired trait in a variety of job descriptions). But it’s better to think of critical thinking less as a distinct skill and more as a collection or category of skills. 

To think critically, you’ll need to tap into a bunch of your other soft skills. Here are seven of the most important. 

Open-mindedness

It’s important to kick off the critical thinking process with the idea that anything is possible. The more you’re able to set aside your own suspicions, beliefs, and agenda, the better prepared you are to approach the situation with the level of inquisitiveness you need. 

That means not closing yourself off to any possibilities and allowing yourself the space to pull on every thread – yes, even the ones that seem totally implausible.

As Christopher Dwyer, Ph.D. writes in a piece for Psychology Today , “Even if an idea appears foolish, sometimes its consideration can lead to an intelligent, critically considered conclusion.” He goes on to compare the critical thinking process to brainstorming . Sometimes the “bad” ideas are what lay the foundation for the good ones. 

Open-mindedness is challenging because it requires more effort and mental bandwidth than sticking with your own perceptions. Approaching problems or situations with true impartiality often means:

• Practicing self-regulation : Giving yourself a pause between when you feel something and when you actually react or take action.
• Challenging your own biases: Acknowledging your biases and seeking feedback are two powerful ways to get a broader understanding. 

Critical thinking example

In a team meeting, your boss mentioned that your company newsletter signups have been decreasing and she wants to figure out why.

At first, you feel offended and defensive – it feels like she’s blaming you for the dip in subscribers. You recognize and rationalize that emotion before thinking about potential causes. You have a hunch about what’s happening, but you will explore all possibilities and contributions from your team members.

Observation

Observation is, of course, your ability to notice and process the details all around you (even the subtle or seemingly inconsequential ones). Critical thinking demands that you’re flexible and willing to go beyond surface-level information, and solid observation skills help you do that.

Your observations help you pick up on clues from a variety of sources and experiences, all of which help you draw a final conclusion. After all, sometimes it’s the most minuscule realization that leads you to the strongest conclusion.

Over the next week or so, you keep a close eye on your company’s website and newsletter analytics to see if numbers are in fact declining or if your boss’s concerns were just a fluke. 

Critical thinking hinges on objectivity. And, to be objective, you need to base your judgments on the facts – which you collect through research. You’ll lean on your research skills to gather as much information as possible that’s relevant to your problem or situation. 

Keep in mind that this isn’t just about the quantity of information – quality matters too. You want to find data and details from a variety of trusted sources to drill past the surface and build a deeper understanding of what’s happening. 

You dig into your email and website analytics to identify trends in bounce rates, time on page, conversions, and more. You also review recent newsletters and email promotions to understand what customers have received, look through current customer feedback, and connect with your customer support team to learn what they’re hearing in their conversations with customers.

The critical thinking process is sort of like a treasure hunt – you’ll find some nuggets that are fundamental for your final conclusion and some that might be interesting but aren’t pertinent to the problem at hand.

That’s why you need analytical skills. They’re what help you separate the wheat from the chaff, prioritize information, identify trends or themes, and draw conclusions based on the most relevant and influential facts. 

It’s easy to confuse analytical thinking with critical thinking itself, and it’s true there is a lot of overlap between the two. But analytical thinking is just a piece of critical thinking. It focuses strictly on the facts and data, while critical thinking incorporates other factors like emotions, opinions, and experiences. 

As you analyze your research, you notice that one specific webpage has contributed to a significant decline in newsletter signups. While all of the other sources have stayed fairly steady with regard to conversions, that one has sharply decreased.

You decide to move on from your other hypotheses about newsletter quality and dig deeper into the analytics. 

One of the traps of critical thinking is that it’s easy to feel like you’re never done. There’s always more information you could collect and more rabbit holes you could fall down.

But at some point, you need to accept that you’ve done your due diligence and make a decision about how to move forward. That’s where inference comes in. It’s your ability to look at the evidence and facts available to you and draw an informed conclusion based on those. 

When you’re so focused on staying objective and pursuing all possibilities, inference can feel like the antithesis of critical thinking. But ultimately, it’s your inference skills that allow you to move out of the thinking process and onto the action steps. 

You dig deeper into the analytics for the page that hasn’t been converting and notice that the sharp drop-off happened around the same time you switched email providers.

After looking more into the backend, you realize that the signup form on that page isn’t correctly connected to your newsletter platform. It seems like anybody who has signed up on that page hasn’t been fed to your email list. 

Communication

3 ways to improve your communication skills at work

If and when you identify a solution or answer, you can’t keep it close to the vest. You’ll need to use your communication skills to share your findings with the relevant stakeholders – like your boss, team members, or anybody who needs to be involved in the next steps.

Your analysis skills will come in handy here too, as they’ll help you determine what information other people need to know so you can avoid bogging them down with unnecessary details. 

In your next team meeting, you pull up the analytics and show your team the sharp drop-off as well as the missing connection between that page and your email platform. You ask the web team to reinstall and double-check that connection and you also ask a member of the marketing team to draft an apology email to the subscribers who were missed. 

Problem-solving

Critical thinking and problem-solving are two more terms that are frequently confused. After all, when you think critically, you’re often doing so with the objective of solving a problem.

The best way to understand how problem-solving and critical thinking differ is to think of problem-solving as much more narrow. You’re focused on finding a solution.

In contrast, you can use critical thinking for a variety of use cases beyond solving a problem – like answering questions or identifying opportunities for improvement. Even so, within the critical thinking process, you’ll flex your problem-solving skills when it comes time to take action. 

Once the fix is implemented, you monitor the analytics to see if subscribers continue to increase. If not (or if they increase at a slower rate than you anticipated), you’ll roll out some other tests like changing the CTA language or the placement of the subscribe form on the page.

5 ways to improve your critical thinking skills

Beyond the buzzwords: Why interpersonal skills matter at work

Think critically about critical thinking and you’ll quickly realize that it’s not as instinctive as you’d like it to be. Fortunately, your critical thinking skills are learned competencies and not inherent gifts – and that means you can improve them. Here’s how:

• Practice active listening: Active listening helps you process and understand what other people share. That’s crucial as you aim to be open-minded and inquisitive.
• Ask open-ended questions: If your critical thinking process involves collecting feedback and opinions from others, ask open-ended questions (meaning, questions that can’t be answered with “yes” or “no”). Doing so will give you more valuable information and also prevent your own biases from influencing people’s input.
• Scrutinize your sources: Figuring out what to trust and prioritize is crucial for critical thinking. Boosting your media literacy and asking more questions will help you be more discerning about what to factor in. It’s hard to strike a balance between skepticism and open-mindedness, but approaching information with questions (rather than unquestioning trust) will help you draw better conclusions. 
• Play a game: Remember those riddles we mentioned at the beginning? As trivial as they might seem, games and exercises like those can help you boost your critical thinking skills. There are plenty of critical thinking exercises you can do individually or as a team . 
• Give yourself time: Research shows that rushed decisions are often regrettable ones. That’s likely because critical thinking takes time – you can’t do it under the wire. So, for big decisions or hairy problems, give yourself enough time and breathing room to work through the process. It’s hard enough to think critically without a countdown ticking in your brain. 

Critical thinking really is critical

The ability to think critically is important, but it doesn’t come naturally to most of us. It’s just easier to stick with biases, assumptions, and surface-level information. 

But that route often leads you to rash judgments, shaky conclusions, and disappointing decisions. So here’s a conclusion we can draw without any more noodling: Even if it is more demanding on your mental resources, critical thinking is well worth the effort.

Critical Thinking and Evaluating Information

Critical Thinking

As a college student, you are tasked with engaging and expanding your thinking skills. One of the most important of these skills is critical thinking because it relates to nearly all tasks, situations, topics, careers, environments, challenges, and opportunities. It is a “domain-general” thinking skill, not one that is specific to a particular subject area.

What Is Critical Thinking?

Critical thinking  is clear, reasonable, reflective thinking focused on deciding what to believe or do. It means asking probing questions like “How do we know?” or “Is this true in every case or just in this instance?” It involves being skeptical and challenging assumptions rather than simply memorizing facts or blindly accepting what you hear or read.

Imagine, for example, that you’re reading a history textbook. You wonder who wrote it and why, because you detect certain biases in the writing. You find that the author has a limited scope of research focused only on a particular group within a population. In this case, your critical thinking reveals that there are “other sides to the story.”

Who are critical thinkers, and what characteristics do they have in common? Critical thinkers are usually curious and reflective people. They like to explore and probe new areas and seek knowledge, clarification, and new solutions. They ask pertinent questions, evaluate statements and arguments, and they distinguish between facts and opinion. They are also willing to examine their own beliefs, possessing a manner of humility that allows them to admit lack of knowledge or understanding when needed. They are open to changing their mind. Perhaps most of all, they actively enjoy learning, and seeking new knowledge is a lifelong pursuit. This may well be you!

No matter where you are on the road to being a critical thinker, you can always more fully develop and finely tune your skills. Doing so will help you develop more balanced arguments, express yourself clearly, read critically, and glean important information efficiently. Critical thinking skills will help you in any profession or any circumstance of life, from science to art to business to teaching. With critical thinking, you become a clearer thinker and problem solver.

Critical Thinking and Logic

Critical thinking is fundamentally a process of questioning information and data. You may question the information you read in a textbook, or you may question what a politician or a professor or a classmate says. You can also question a commonly-held belief or a new idea. With critical thinking, anything and everything is subject to question and examination for the purpose of logically constructing reasoned perspectives.

What Is Logic?

The word  logic  comes from the Ancient Greek  logike , referring to the science or art of reasoning. Using logic, a person evaluates arguments and reasoning and strives to distinguish between good and bad reasoning, or between truth and falsehood. Using logic, you can evaluate the ideas and claims of others, make good decisions, and form sound beliefs about the world. [1]

Questions of Logic in Critical Thinking

Let’s use a simple example of applying logic to a critical-thinking situation. In this hypothetical scenario, a man has a Ph.D. in political science, and he works as a professor at a local college. His wife works at the college, too. They have three young children in the local school system, and their family is well known in the community. The man is now running for political office. Are his credentials and experience sufficient for entering public office? Will he be effective in the political office? Some voters might believe that his personal life and current job, on the surface, suggest he will do well in the position, and they will vote for him. In truth, the characteristics described don’t guarantee that the man will do a good job. The information is somewhat irrelevant. What else might you want to know? How about whether the man had already held a political office and done a good job? In this case, we want to think critically about how much information is adequate in order to make a decision based on  logic  instead of  assumptions.

The following questions, presented in Figure 1, below, are ones you may apply to formulating a logical, reasoned perspective in the above scenario or any other situation:

• What’s happening?  Gather the basic information and begin to think of questions.
• Why is it important?  Ask yourself why it’s significant and whether or not you agree.
• What don’t I see?  Is there anything important missing?
• How do I know?  Ask yourself where the information came from and how it was constructed.
• Who is saying it?  What’s the position of the speaker and what is influencing them?
• What else?   What if?  What other ideas exist and are there other possibilities?

Problem-Solving with Critical Thinking

For most people, a typical day is filled with critical thinking and problem-solving challenges. In fact, critical thinking and problem-solving go hand-in-hand. They both refer to using knowledge, facts, and data to solve problems effectively. But with problem-solving, you are specifically identifying, selecting, and defending your solution. Below are some examples of using critical thinking to problem-solve:

• Your roommate was upset and said some unkind words to you, which put a crimp in the relationship. You try to see through the angry behaviors to determine how you might best support the roommate and help bring the relationship back to a comfortable spot.
• Your campus club has been languishing due to lack of participation and funds. The new club president, though, is a marketing major and has identified some strategies to interest students in joining and supporting the club. Implementation is forthcoming.
• Your final art class project challenges you to conceptualize form in new ways. On the last day of class when students present their projects, you describe the techniques you used to fulfill the assignment. You explain why and how you selected that approach.
• Your math teacher sees that the class is not quite grasping a concept. She uses clever questioning to dispel anxiety and guide you to a new understanding of the concept.
• You have a job interview for a position that you feel you are only partially qualified for, although you really want the job and you are excited about the prospects. You analyze how you will explain your skills and experiences in a way to show that you are a good match for the prospective employer.
• You are doing well in college, and most of your college and living expenses are covered. But there are some gaps between what you want and what you feel you can afford. You analyze your income, savings, and budget to better calculate what you will need to stay in college and maintain your desired level of spending.

Problem-Solving Action Checklist

Problem-solving can be an efficient and rewarding process, especially if you are organized and mindful of critical steps and strategies. Remember to assume the attributes of a good critical thinker: if you are curious, reflective, knowledge-seeking, open to change, probing, organized, and ethical, your challenge or problem will be less of a hurdle, and you’ll be in a good position to find intelligent solutions. The steps outlined in this checklist will help you adhere to these qualities in your approach to any problem:

Critical and Creative Thinking

Critical and creative thinking (described in more detail in Chapter 6: Theories of Learning) complement each other when it comes to problem-solving. The following words, by Dr. Andrew Robert Baker, are excerpted from his “Thinking Critically and Creatively” essay. Dr. Baker illuminates some of the many ways that college students will be exposed to critical and creative thinking and how it can enrich their learning experiences.

THINKING CRITICALLY AND CREATIVELY Critical thinking skills are perhaps the most fundamental skills involved in making judgments and solving problems. You use them every day, and you can continue improving them. The ability to think critically about a matter—to analyze a question, situation, or problem down to its most basic parts—is what helps us evaluate the accuracy and truthfulness of statements, claims, and information we read and hear. It is the sharp knife that, when honed, separates fact from fiction, honesty from lies, and the accurate from the misleading. We all use this skill to one degree or another almost every day. For example, we use critical thinking every day as we consider the latest consumer products and why one particular product is the best among its peers. Is it a quality product because a celebrity endorses it? Because a lot of other people may have used it? Because it is made by one company versus another? Or perhaps because it is made in one country or another? These are questions representative of critical thinking. The academic setting demands more of us in terms of critical thinking than everyday life. It demands that we evaluate information and analyze myriad issues. It is the environment where our critical thinking skills can be the difference between success and failure. In this environment we must consider information in an analytical, critical manner. We must ask questions—What is the source of this information? Is this source an expert one and what makes it so? Are there multiple perspectives to consider on an issue? Do multiple sources agree or disagree on an issue? Does quality research substantiate information or opinion? Do I have any personal biases that may affect my consideration of this information? It is only through purposeful, frequent, intentional questioning such as this that we can sharpen our critical thinking skills and improve as students, learners and researchers. While critical thinking analyzes information and roots out the true nature and facets of problems, it is creative thinking that drives progress forward when it comes to solving these problems. Exceptional creative thinkers are people that invent new solutions to existing problems that do not rely on past or current solutions. They are the ones who invent solution C when everyone else is still arguing between A and B. Creative thinking skills involve using strategies to clear the mind so that our thoughts and ideas can transcend the current limitations of a problem and allow us to see beyond barriers that prevent new solutions from being found. Brainstorming is the simplest example of intentional creative thinking that most people have tried at least once. With the quick generation of many ideas at once, we can block-out our brain’s natural tendency to limit our solution-generating abilities so we can access and combine many possible solutions/thoughts and invent new ones. It is sort of like sprinting through a race’s finish line only to find there is new track on the other side and we can keep going, if we choose. As with critical thinking, higher education both demands creative thinking from us and is the perfect place to practice and develop the skill. Everything from word problems in a math class, to opinion or persuasive speeches and papers, call upon our creative thinking skills to generate new solutions and perspectives in response to our professor’s demands. Creative thinking skills ask questions such as—What if? Why not? What else is out there? Can I combine perspectives/solutions? What is something no one else has brought-up? What is being forgotten/ignored? What about ______? It is the opening of doors and options that follows problem-identification. Consider an assignment that required you to compare two different authors on the topic of education and select and defend one as better. Now add to this scenario that your professor clearly prefers one author over the other. While critical thinking can get you as far as identifying the similarities and differences between these authors and evaluating their merits, it is creative thinking that you must use if you wish to challenge your professor’s opinion and invent new perspectives on the authors that have not previously been considered. So, what can we do to develop our critical and creative thinking skills? Although many students may dislike it, group work is an excellent way to develop our thinking skills. Many times I have heard from students their disdain for working in groups based on scheduling, varied levels of commitment to the group or project, and personality conflicts too, of course. True—it’s not always easy, but that is why it is so effective. When we work collaboratively on a project or problem we bring many brains to bear on a subject. These different brains will naturally develop varied ways of solving or explaining problems and examining information. To the observant individual we see that this places us in a constant state of back and forth critical/creative thinking modes. For example, in group work we are simultaneously analyzing information and generating solutions on our own, while challenging other’s analyses/ideas and responding to challenges to our own analyses/ideas. This is part of why students tend to avoid group work—it challenges us as thinkers and forces us to analyze others while defending ourselves, which is not something we are used to or comfortable with as most of our educational experiences involve solo work. Your professors know this—that’s why we assign it—to help you grow as students, learners, and thinkers! —Dr. Andrew Robert Baker,  Foundations of Academic Success: Words of Wisdom

Evaluating Information with Critical Thinking

Evaluating information can be one of the most complex tasks you will be faced with in college. But if you utilize the following four strategies, you will be well on your way to success:

• Read for understanding
• Examine arguments
• Clarify thinking
• Cultivate “habits of mind”

Read for Understanding

When you read, take notes or mark the text to track your thinking about what you are reading. As you make connections and ask questions in response to what you read,  you monitor your comprehension and enhance your long-term understanding of the material. You will want to mark important arguments and key facts. Indicate where you agree and disagree or have further questions. You don’t necessarily need to read every word, but make sure you understand the concepts or the intentions behind what is written. See the chapter on  Active Reading Strategies  for additional tips.

Examine Arguments

When you examine arguments or claims that an author, speaker, or other source is making, your goal is to identify and examine the hard facts. You can use the spectrum of authority strategy for this purpose. The spectrum of authority strategy assists you in identifying the “hot” end of an argument—feelings, beliefs, cultural influences, and societal influences—and the “cold” end of an argument—scientific influences. The most compelling arguments balance elements from both ends of the spectrum. The following video explains this strategy in further detail:

Clarify Thinking

When you use critical thinking to evaluate information, you need to clarify your thinking to yourself and likely to others. Doing this well is mainly a process of asking and answering probing questions, such as the logic questions discussed earlier. Design your questions to fit your needs, but be sure to cover adequate ground. What is the purpose? What question are we trying to answer? What point of view is being expressed? What assumptions are we or others making? What are the facts and data we know, and how do we know them? What are the concepts we’re working with? What are the conclusions, and do they make sense? What are the implications?

Cultivate “Habits of Mind”

“Habits of mind” are the personal commitments, values, and standards you have about the principle of good thinking. Consider your intellectual commitments, values, and standards. Do you approach problems with an open mind, a respect for truth, and an inquiring attitude? Some good habits to have when thinking critically are being receptive to having your opinions changed, having respect for others, being independent and not accepting something is true until you’ve had the time to examine the available evidence, being fair-minded, having respect for a reason, having an inquiring mind, not making assumptions, and always, especially, questioning your own conclusions—in other words, developing an intellectual work ethic. Try to work these qualities into your daily life.

In 2010, a textbook being used in fourth-grade classrooms in Virginia became big news for all the wrong reasons. The book,  Our Virginia  by Joy Masoff, had caught the attention of a parent who was helping her child do her homework, according to  an article in  The Washington Post . Carol Sheriff was a historian for the College of William and Mary and as she worked with her daughter, she began to notice some glaring historical errors, not the least of which was a passage which described how thousands of African Americans fought for the South during the Civil War.

Further investigation into the book revealed that, although the author had written textbooks on a variety of subjects, she was not a trained historian. The research she had done to write  Our Virginia,  and in particular the information she included about Black Confederate soldiers, was done through the Internet and included sources created by groups like the Sons of Confederate Veterans, an organization which promotes views of history that de-emphasize the role of slavery in the Civil War.

How did a book with errors like these come to be used as part of the curriculum and who was at fault? Was it Masoff for using untrustworthy sources for her research? Was it the editors who allowed the book to be published with these errors intact? Was it the school board for approving the book without more closely reviewing its accuracy?

There are a number of issues at play in the case of  Our Virginia , but there’s no question that evaluating sources is an important part of the research process and doesn’t just apply to Internet sources. Using inaccurate, irrelevant, or poorly researched sources can affect the quality of your own work. Being able to understand and apply the concepts that follow is crucial to becoming a more savvy user and creator of information.

When you begin evaluating sources, what should you consider? The  CRAAP test  is a series of common evaluative elements you can use to evaluate the  C urrency,  R elevance,  A uthority,  A ccuracy, and  P urpose of your sources. The CRAAP test was developed by librarians at California State University at Chico and it gives you a good, overall set of elements to look for when evaluating a resource. Let’s consider what each of these evaluative elements means. You can visit the ACC Library’s Web page for a tutorial on  Evaluating Information  using the CRAAP test.

One of the most important and interesting steps to take as you begin researching a subject is selecting the resources that will help you build your thesis and support your assertions. Certain topics require you to pay special attention to how current your resource is—because they are time sensitive, because they have evolved so much over the years, or because new research comes out on the topic so frequently. When evaluating the currency of an article, consider the following:

• When was the item written, and how frequently does the publication come out?
• Is there evidence of newly added or updated information in the item?
• If the information is dated, is it still suitable for your topic?
• How frequently does information change about your topic?

Understanding what resources are most applicable to your subject and why they are applicable can help you focus and refine your thesis. Many topics are broad and searching for information on them produces a wide range of resources. Narrowing your topic and focusing on resources specific to your needs can help reduce the piles of information and help you focus in on what is truly important to read and reference. When determining relevance consider the following:

• Does the item contain information relevant to your argument or thesis?
• Read the article’s introduction, thesis, and conclusion.
• Scan main headings and identify article keywords.
• For book resources, start with the index or table of contents—how wide a scope does the item have? Will you use part or all of this resource?
• Does the information presented support or refute your ideas?
• If the information refutes your ideas, how will this change your argument?
• Does the material provide you with current information?
• What is the material’s intended audience?

Understanding more about your information’s source helps you determine when, how, and where to use that information. Is your author an expert on the subject? Do they have some personal stake in the argument they are making? What is the author or information producer’s background? When determining the authority of your source, consider the following:

• What are the author’s credentials?
• What is the author’s level of education, experience, and/or occupation?
• What qualifies the author to write about this topic?
• What affiliations does the author have? Could these affiliations affect their position?
• What organization or body published the information? Is it authoritative? Does it have an explicit position or bias?

Determining where information comes from, if the evidence supports the information, and if the information has been reviewed or refereed can help you decide how and whether to use a source. When determining the accuracy of a source, consider the following:

• Is the source well-documented? Does it include footnotes, citations, or a bibliography?
• Is information in the source presented as fact, opinion, or propaganda? Are biases clear?
• Can you verify information from the references cited in the source?
• Is the information written clearly and free of typographical and grammatical mistakes? Does the source look to be edited before publication? A clean, well-presented paper does not always indicate accuracy, but usually at least means more eyes have been on the information.

Knowing why the information was created is a key to evaluation. Understanding the reason or purpose of the information, if the information has clear intentions, or if the information is fact, opinion, or propaganda will help you decide how and why to use information:

• Is the author’s purpose to inform, sell, persuade, or entertain?
• Does the source have an obvious bias or prejudice?
• Is the article presented from multiple points of view?
• Does the author omit important facts or data that might disprove their argument?
• Is the author’s language informal, joking, emotional, or impassioned?
• Is the information clearly supported by evidence?

When you feel overwhelmed by the information you are finding, the CRAAP test can help you determine which information is the most useful to your research topic. How you respond to what you find out using the CRAAP test will depend on your topic. Maybe you want to use two overtly biased resources to inform an overview of typical arguments in a particular field. Perhaps your topic is historical and currency means the past hundred years rather than the past one or two years. Use the CRAAP test, be knowledgeable about your topic, and you will be on your way to evaluating information efficiently and well!

Developing Yourself As a Critical Thinker

Critical thinking is a fundamental skill for college students, but it should also be a lifelong pursuit. Below are additional strategies to develop yourself as a critical thinker in college and in everyday life:

• Reflect and practice : Always reflect on what you’ve learned. Is it true all the time? How did you arrive at your conclusions?
• Use wasted time : It’s certainly important to make time for relaxing, but if you find you are indulging in too much of a good thing, think about using your time more constructively. Determine when you do your best thinking and try to learn something new during that part of the day.
• Redefine the way you see things : It can be very uninteresting to always think the same way. Challenge yourself to see familiar things in new ways. Put yourself in someone else’s shoes and consider things from a different angle or perspective.  If you’re trying to solve a problem, list all your concerns: what you need in order to solve it, who can help, what some possible barriers might be, etc. It’s often possible to reframe a problem as an opportunity. Try to find a solution where there seems to be none.
• Analyze the influences on your thinking and in your life : Why do you think or feel the way you do? Analyze your influences. Think about who in your life influences you. Do you feel or react a certain way because of social convention, or because you believe it is what is expected of you? Try to break out of any molds that may be constricting you.
• Express yourself : Critical thinking also involves being able to express yourself clearly. Most important in expressing yourself clearly is stating one point at a time. You might be inclined to argue every thought, but you might have greater impact if you focus just on your main arguments. This will help others to follow your thinking clearly. For more abstract ideas, assume that your audience may not understand. Provide examples, analogies, or metaphors where you can.
• Enhance your wellness : It’s easier to think critically when you take care of your mental and physical health. Try taking activity breaks throughout the day to reach 30 to 60 minutes of physical activity each day. Scheduling physical activity into your day can help lower stress and increase mental alertness. Also,  do your most difficult work when you have the most energy . Think about the time of day you are most effective and have the most energy. Plan to do your most difficult work during these times. And be sure to  reach out for help i f you feel you need assistance with your mental or physical health (see  Maintaining Your Mental and Physical Health  for more information).

Facts Are Absolute Truth

We define facts as “absolute truth” in critical thinking. With facts, there is no debate. You are reading this right now; that's a fact. Facts are facts; they aren't hearsay, opinions, or rumors.

However, when someone says, “Here are the facts,” that doesn't mean what follows is factual. Remember the most recent presidential (or really, any political) debate? Both candidates stood up and said, “Here are the facts,” yet they contradicted each other. Facts can't be contradictory if they are indeed the one and only truth. So the facts the candidates were throwing at us were not really facts . You could even read in the paper the next day how un factual their facts were.

When you hear something over and over and over again, you might mistakenly think it's a fact. When someone with great credibility says something, you might assume it's a fact. In either instance, it might be a fact—but unless you know the information to be true, it may not be.

Facts are a very important part of your premise. Because they are absolute truth, you can bank on, leverage, and state facts with confidence. It makes a premise strong. You can come to highly reliable conclusions if you base those conclusions on facts alone. Facts are often the basis for deductive reasoning. Although you don't get to use deductive reasoning often, when you do, it results in correct conclusions.

Mathematics is based on facts. Laws and rules are often used as facts. Science creates rules that, until ...

How to Practice and Use Critical Thinking

The critical thinking process incorporates various other logical soft skills that will help you analyze and interpret all the information to create an informed decision. These soft skills include observational skills, problem-solving, communication skills, and analytical thinking. If you sharpen all of these elements and characteristics you will inadvertently enhance your critical thinking.

Step 1: Practice One’s Observational and Perception Skills

We use our senses to perceive the world around us, whether it would be sight, smell, a, and sensations. One should practice utilizing these senses to create logical inferences and deductions that will help out brain unconsciously absorb and analyze these types of information. The more one practices their senses the better their thinking process will be.

Step 2: Enhance One’s Problem-Solving Skills

Logic and problem-solving allow the person to deduce and connect information that the environment or circumstance presents to the said person. You need to practice your problem-solving skills via puzzles, logical reasoning tests, and ethical dilemmas. Practicing one’s problem-solving skills will allow the person to efficiently establish cause-and-effect  reasoning or properly create logical decisions.

Step 3: Prepare and Practice One’s Communication Skills

Communication is a pivotal skill we often use when interacting with other people. This type of skill includes body language , assertive communication , concise language, and other communication skills. In critical thinking, a person must be able to properly communicate their thoughts and thinking process to other people, which will create a collaborative environment. Other times, the perfect solution might not be present without the need for communication.

Step 4: Practice Analysis of the Situation

One’s analytical thinking skills allow the person to take note of various elements and characteristics of the situation and analyze these elements’ contribution to the current situation or circumstance. You need to practice your analytical thinking to properly process the current situation or circumstance you find yourself in.

How to build your critical thinking skills in 7 steps (with examples)

Critical thinking is, well, critical. By building these skills, you improve your ability to analyze information and come to the best decision possible. In this article, we cover the basics of critical thinking, as well as the seven steps you can use to implement the full critical thinking process. 

Critical thinking comes from asking the right questions to come to the best conclusion possible. Strong critical thinkers analyze information from a variety of viewpoints in order to identify the best course of action.

Don’t worry if you don’t think you have strong critical thinking abilities. In this article, we’ll help you build a foundation for critical thinking so you can absorb, analyze, and make informed decisions. 

What is critical thinking? 

Critical thinking is the ability to collect and analyze information to come to a conclusion. Being able to think critically is important in virtually every industry and applicable across a wide range of positions. That’s because critical thinking isn’t subject-specific—rather, it’s your ability to parse through information, data, statistics, and other details in order to identify a satisfactory solution. 

Decision-making tools for agile businesses

In this ebook, learn how to equip employees to make better decisions—so your business can pivot, adapt, and tackle challenges more effectively than your competition.

Top 8 critical thinking skills

Like most soft skills, critical thinking isn’t something you can take a class to learn. Rather, this skill consists of a variety of interpersonal and analytical skills. Developing critical thinking is more about learning to embrace open-mindedness and bringing analytical thinking to your problem framing process. 

In no particular order, the eight most important critical thinking skills are:

Analytical thinking: Part of critical thinking is evaluating data from multiple sources in order to come to the best conclusions. Analytical thinking allows people to reject bias and strive to gather and consume information to come to the best conclusion. 

Open-mindedness: This critical thinking skill helps you analyze and process information to come to an unbiased conclusion. Part of the critical thinking process is letting your personal biases go and coming to a conclusion based on all of the information. 

Problem solving : Because critical thinking emphasizes coming to the best conclusion based on all of the available information, it’s a key part of problem solving. When used correctly, critical thinking helps you solve any problem—from a workplace challenge to difficulties in everyday life. 

Self-regulation: Self-regulation refers to the ability to regulate your thoughts and set aside any personal biases to come to the best conclusion. In order to be an effective critical thinker, you need to question the information you have and the decisions you favor—only then can you come to the best conclusion. 

Observation: Observation skills help critical thinkers look for things beyond face value. To be a critical thinker you need to embrace multiple points of view, and you can use observation skills to identify potential problems.

Interpretation: Not all data is made equal—and critical thinkers know this. In addition to gathering information, it’s important to evaluate which information is important and relevant to your situation. That way, you can draw the best conclusions from the data you’ve collected. 

Evaluation: When you attempt to answer a hard question, there is rarely an obvious answer. Even though critical thinking emphasizes putting your biases aside, you need to be able to confidently make a decision based on the data you have available. 

Communication: Once a decision has been made, you also need to share this decision with other stakeholders. Effective workplace communication includes presenting evidence and supporting your conclusion—especially if there are a variety of different possible solutions. 

7 steps to critical thinking

Critical thinking is a skill that you can build by following these seven steps. The seven steps to critical thinking help you ensure you’re approaching a problem from the right angle, considering every alternative, and coming to an unbiased conclusion.

 First things first: When to use the 7 step critical thinking process

There’s a lot that goes into the full critical thinking process, and not every decision needs to be this thought out. Sometimes, it’s enough to put aside bias and approach a process logically. In other, more complex cases, the best way to identify the ideal outcome is to go through the entire critical thinking process. 

The seven-step critical thinking process is useful for complex decisions in areas you are less familiar with. Alternatively, the seven critical thinking steps can help you look at a problem you’re familiar with from a different angle, without any bias. 

If you need to make a less complex decision, consider another problem solving strategy instead. Decision matrices are a great way to identify the best option between different choices. Check out our article on 7 steps to creating a decision matrix .

1. Identify the problem

Before you put those critical thinking skills to work, you first need to identify the problem you’re solving. This step includes taking a look at the problem from a few different perspectives and asking questions like: 

What’s happening? 

Why is this happening? 

What assumptions am I making? 

At first glance, how do I think we can solve this problem? 

A big part of developing your critical thinking skills is learning how to come to unbiased conclusions. In order to do that, you first need to acknowledge the biases that you currently have. Does someone on your team think they know the answer? Are you making assumptions that aren’t necessarily true? Identifying these details helps you later on in the process. 

2. Research

At this point, you likely have a general idea of the problem—but in order to come up with the best solution, you need to dig deeper. 

During the research process, collect information relating to the problem, including data, statistics, historical project information, team input, and more. Make sure you gather information from a variety of sources, especially if those sources go against your personal ideas about what the problem is or how to solve it.

Gathering varied information is essential for your ability to apply the critical thinking process. If you don’t get enough information, your ability to make a final decision will be skewed. Remember that critical thinking is about helping you identify the objective best conclusion. You aren’t going with your gut—you’re doing research to find the best option

3. Determine data relevance

Just as it’s important to gather a variety of information, it is also important to determine how relevant the different information sources are. After all, just because there is data doesn’t mean it’s relevant. 

Once you’ve gathered all of the information, sift through the noise and identify what information is relevant and what information isn’t. Synthesizing all of this information and establishing significance helps you weigh different data sources and come to the best conclusion later on in the critical thinking process. 

To determine data relevance, ask yourself:

How reliable is this information? 

How significant is this information? 

Is this information outdated? Is it specialized in a specific field? 

4. Ask questions

One of the most useful parts of the critical thinking process is coming to a decision without bias. In order to do so, you need to take a step back from the process and challenge the assumptions you’re making. 

We all have bias—and that isn’t necessarily a bad thing. Unconscious biases (also known as cognitive biases) often serve as mental shortcuts to simplify problem solving and aid decision making. But even when biases aren’t inherently bad, you must be aware of your biases in order to put them aside when necessary. 

Before coming to a solution, ask yourself:

Am I making any assumptions about this information? 

Are there additional variables I haven’t considered? 

Have I evaluated the information from every perspective? 

Are there any viewpoints I missed? 

5. Identify the best solution

Finally, you’re ready to come to a conclusion. To identify the best solution, draw connections between causes and effects. Use the facts you’ve gathered to evaluate the most objective conclusion. 

Keep in mind that there may be more than one solution. Often, the problems you’re facing are complex and intricate. The critical thinking process doesn’t necessarily lead to a cut-and-dry solution—instead, the process helps you understand the different variables at play so you can make an informed decision. 

6. Present your solution

Communication is a key skill for critical thinkers. It isn’t enough to think for yourself—you also need to share your conclusion with other project stakeholders. If there are multiple solutions, present them all. There may be a case where you implement one solution, then test to see if it works before implementing another solution. 

7. Analyze your decision

The seven-step critical thinking process yields a result—and you then need to put that solution into place. After you’ve implemented your decision, evaluate whether or not it was effective. Did it solve the initial problem? What lessons—whether positive or negative—can you learn from this experience to improve your critical thinking for next time? 

Depending on how your team shares information, consider documenting lessons learned in a central source of truth. That way, team members that are making similar or related decisions in the future can understand why you made the decision you made and what the outcome was. 

Example of critical thinking in the workplace

Imagine you work in user experience design (UX). Your team is focused on pricing and packaging and ensuring customers have a clear understanding of the different services your company offers. Here’s how to apply the critical thinking process in the workplace in seven steps: 

Start by identifying the problem

Your current pricing page isn’t performing as well as you want. You’ve heard from customers that your services aren’t clear, and that the page doesn’t answer the questions they have. This page is really important for your company, since it’s where your customers sign up for your service. You and your team have a few theories about why your current page isn’t performing well, but you decide to apply the critical thinking process to ensure you come to the best decision for the page. 

Gather information about how the problem started

Part of identifying the problem includes understanding how the problem started. The pricing and packaging page is important—so when your team initially designed the page, they certainly put a lot of thought into it. Before you begin researching how to improve the page, ask yourself: 

Why did you design the pricing page the way you did? 

Which stakeholders need to be involved in the decision making process? 

Where are users getting stuck on the page?

Are any features currently working?

Then, you research

In addition to understanding the history of the pricing and packaging page, it’s important to understand what works well. Part of this research means taking a look at what your competitor’s pricing pages look like. 

Ask yourself: 

How have our competitors set up their pricing pages?

Are there any pricing page best practices? 

How does color, positioning, and animation impact navigation? 

Are there any standard page layouts customers expect to see? 

Organize and analyze information

You’ve gathered all of the information you need—now you need to organize and analyze it. What trends, if any, are you noticing? Is there any particularly relevant or important information that you have to consider? 

Ask open-ended questions to reduce bias

In the case of critical thinking, it’s important to address and set bias aside as much as possible. Ask yourself: 

Is there anything I’m missing? 

Have I connected with the right stakeholders? 

Are there any other viewpoints I should consider? 

Determine the best solution for your team

You now have all of the information you need to design the best pricing page. Depending on the complexity of the design, you may want to design a few options to present to a small group of customers or A/B test on the live website.

Present your solution to stakeholders

Critical thinking can help you in every element of your life, but in the workplace, you must also involve key project stakeholders . Stakeholders help you determine next steps, like whether you’ll A/B test the page first. Depending on the complexity of the issue, consider hosting a meeting or sharing a status report to get everyone on the same page. 

Analyze the results

No process is complete without evaluating the results. Once the new page has been live for some time, evaluate whether it did better than the previous page. What worked? What didn’t? This also helps you make better critical decisions later on.

Critically successful 

Critical thinking takes time to build, but with effort and patience you can apply an unbiased, analytical mind to any situation. Critical thinking makes up one of many soft skills that makes you an effective team member, manager, and worker.

Published: April 2, 2020

Why is critical thinking important? The decisions that you make affect your quality of life. And if you want to ensure that you live your best, most successful and happy life, you’re going to want to make conscious choices. That can be done with a simple thing known as critical thinking. Here’s how to improve your critical thinking skills and make decisions that you won’t regret.

What Is Critical Thinking?

You’ve surely heard of critical thinking, but you might not be entirely sure what it really means, and that’s because there are many definitions. For the most part, however, we think of critical thinking as the process of analyzing facts in order to form a judgment. Basically, it’s thinking about thinking.

How Has The Definition Evolved Over Time?

The first time critical thinking was documented is believed to be in the teachings of Socrates , recorded by Plato. But throughout history, the definition has changed.

Today it is best understood by philosophers and psychologists and it’s believed to be a highly complex concept. Some insightful modern-day critical thinking definitions include :

• “Reasonable, reflective thinking that is focused on deciding what to believe or do.”
• “Deciding what’s true and what you should do.”

The Importance Of Critical Thinking

Why is critical thinking important? Good question! Here are a few undeniable reasons why it’s crucial to have these skills.

1. Critical Thinking Is Universal

Critical thinking is a domain-general thinking skill. What does this mean? It means that no matter what path or profession you pursue, these skills will always be relevant and will always be beneficial to your success. They are not specific to any field.

6. The Basis Of Science & Democracy

In order to have a democracy and to prove scientific facts, we need critical thinking in the world. Theories must be backed up with knowledge. In order for a society to effectively function, its citizens need to establish opinions about what’s right and wrong (by using critical thinking!).

Benefits Of Critical Thinking

We know that critical thinking is good for society as a whole, but what are some benefits of critical thinking on an individual level? Why is critical thinking important for us?

1. Key For Career Success

Critical thinking is crucial for many career paths. Not just for scientists, but lawyers , doctors, reporters, engineers , accountants, and analysts (among many others) all have to use critical thinking in their positions. In fact, according to the World Economic Forum, critical thinking is one of the most desirable skills to have in the workforce, as it helps analyze information, think outside the box, solve problems with innovative solutions, and plan systematically.

2. Better Decision Making

There’s no doubt about it — critical thinkers make the best choices. Critical thinking helps us deal with everyday problems as they come our way, and very often this thought process is even done subconsciously. It helps us think independently and trust our gut feeling.

3. Can Make You Happier!

While this often goes unnoticed, being in touch with yourself and having a deep understanding of why you think the way you think can really make you happier. Critical thinking can help you better understand yourself, and in turn, help you avoid any kind of negative or limiting beliefs, and focus more on your strengths. Being able to share your thoughts can increase your quality of life.

4. Form Well-Informed Opinions

There is no shortage of information coming at us from all angles. And that’s exactly why we need to use our critical thinking skills and decide for ourselves what to believe. Critical thinking allows us to ensure that our opinions are based on the facts, and help us sort through all that extra noise.

5. Better Citizens

One of the most inspiring critical thinking quotes is by former US president Thomas Jefferson: “An educated citizenry is a vital requisite for our survival as a free people.” What Jefferson is stressing to us here is that critical thinkers make better citizens, as they are able to see the entire picture without getting sucked into biases and propaganda.

6. Improves Relationships

While you may be convinced that being a critical thinker is bound to cause you problems in relationships, this really couldn’t be less true! Being a critical thinker can allow you to better understand the perspective of others, and can help you become more open-minded towards different views.

7. Promotes Curiosity

Critical thinkers are constantly curious about all kinds of things in life, and tend to have a wide range of interests. Critical thinking means constantly asking questions and wanting to know more, about why, what, who, where, when, and everything else that can help them make sense of a situation or concept, never taking anything at face value.

8. Allows For Creativity

Critical thinkers are also highly creative thinkers, and see themselves as limitless when it comes to possibilities. They are constantly looking to take things further, which is crucial in the workforce.

9. Enhances Problem Solving Skills

Those with critical thinking skills tend to solve problems as part of their natural instinct. Critical thinkers are patient and committed to solving the problem, similar to Albert Einstein, one of the best critical thinking examples, who said “It’s not that I’m so smart; it’s just that I stay with problems longer.” Critical thinkers’ enhanced problem-solving skills makes them better at their jobs and better at solving the world’s biggest problems. Like Einstein, they have the potential to literally change the world.

10. An Activity For The Mind

Just like our muscles, in order for them to be strong, our mind also needs to be exercised and challenged. It’s safe to say that critical thinking is almost like an activity for the mind — and it needs to be practiced. Critical thinking encourages the development of many crucial skills such as logical thinking, decision making, and open-mindness.

11. Creates Independence

When we think critically, we think on our own as we trust ourselves more. Critical thinking is key to creating independence, and encouraging students to make their own decisions and form their own opinions.

12. Crucial Life Skill

Critical thinking is crucial not just for learning, but for life overall! Education isn’t just a way to prepare ourselves for life, but it’s pretty much life itself. Learning is a lifelong process that we go through each and every day.

How to Think Critically

Now that you know the benefits of thinking critically, how do you actually do it?

How To Improve Your Critical Thinking

• Define Your Question: When it comes to critical thinking, it’s important to always keep your goal in mind. Know what you’re trying to achieve, and then figure out how to best get there.
• Gather Reliable Information: Make sure that you’re using sources you can trust — biases aside. That’s how a real critical thinker operates!
• Ask The Right Questions: We all know the importance of questions, but be sure that you’re asking the right questions that are going to get you to your answer.
• Look Short & Long Term: When coming up with solutions, think about both the short- and long-term consequences. Both of them are significant in the equation.
• Explore All Sides: There is never just one simple answer, and nothing is black or white. Explore all options and think outside of the box before you come to any conclusions.

How Is Critical Thinking Developed At School?

Critical thinking is developed in nearly everything we do. However, much of this important skill is encouraged to be practiced at school, and rightfully so! Critical thinking goes beyond just thinking clearly — it’s also about thinking for yourself.

When a teacher asks a question in class, students are given the chance to answer for themselves and think critically about what they learned and what they believe to be accurate. When students work in groups and are forced to engage in discussion, this is also a great chance to expand their thinking and use their critical thinking skills.

How Does Critical Thinking Apply To Your Career?

Once you’ve finished school and entered the workforce, your critical thinking journey only expands and grows from here!

Impress Your Employer

Employers value employees who are critical thinkers, ask questions, offer creative ideas, and are always ready to offer innovation against the competition. No matter what your position or role in a company may be, critical thinking will always give you the power to stand out and make a difference.

Careers That Require Critical Thinking

Some of many examples of careers that require critical thinking include:

• Human resources specialist
• Marketing associate

How to Evaluate Sources Using Critical Thinking: A Concise Guide to Informed Research

In today’s world, the internet provides us with a wealth of information , but not all of it is trustworthy. Knowing how to evaluate sources is an essential skill, especially when conducting research or seeking reliable information. Critical thinking plays a vital role in this process, as it allows individuals to assess the credibility, relevance, and quality of sources.

When evaluating sources, it is crucial to identify the purpose and audience of the content, as well as the objectivity and potential biases that may be present. In addition, it is important to assess the relevance and value of the information provided, and consider its currency and accuracy. Recognizing any potential errors or limitations in the sources can help eliminate unreliable information from your research or decision-making process.

Key Takeaways

• Critical thinking is essential for evaluating the credibility, relevance, and quality of sources.
• Consideration of purpose, audience, and objectivity helps in assessing the reliability of information.
• Evaluating currency, accuracy, and potential limitations leads to well-informed decision making.

Identifying Reliable Sources

When conducting research, it is essential to use credible sources to ensure the accuracy and validity of your work. To identify reliable sources, it’s crucial to employ critical thinking skills and assess each source’s authority, publisher, credentials, and affiliations.

A credible source is typically authored by a person with relevant expertise in the field. Assessing the author’s credentials, such as their degrees, certifications, or professional experience, can provide insight into their authority on the subject. Additionally, considering the author’s affiliations and potential biases can help determine the reliability of the information presented.

Publisher reputation is another important factor when evaluating sources. Reputable publishers, such as peer-reviewed journals, academic institutions, or respected news organizations, undergo rigorous editorial processes to ensure the accuracy of their content. Checking the publisher’s guidelines and standards can provide further assurance of a source’s reliability.

When analyzing the content itself, the presence of citations and references adds credibility, as it demonstrates that the author’s claims are based on existing research. Well-reasoned and balanced arguments, supported by evidence, are also indicators of a reputable source.

In some cases, it may be useful to compare multiple sources to validate the information and identify potential discrepancies. This is particularly helpful in situations where not all sources may be equally trustworthy.

Applying these critical thinking skills can help ensure that the sources you choose for your research are reliable and contribute to a well-founded and accurate final product.

Assessing Source Credibility

Evaluating sources using critical thinking is essential for determining their credibility. Assessing source credibility involves examining various aspects of the information and the source itself to ensure its accuracy, relevance, and trustworthiness.

The first step in assessing credibility is to examine the relevance of the source to the research topic. The information provided should directly contribute to understanding, answering, or supporting the subject in question. Irrelevant sources can lead to inaccurate conclusions and detract from the validity of the research.

Credibility is another important factor to consider. This involves evaluating whether the source is authored by experts in the field, affiliated with a reputable institution, or published in a well-known and respected journal or platform. A credible source will have expertise or qualifications that lend authority to the presented information.

Determining the trustworthiness of a source can be achieved by considering the accuracy of the information and data provided. Cross-referencing the mentioned facts with other reputable sources may reveal inconsistencies that suggest unreliable information. Trustworthy sources often cite their sources and provide enough detail to verify their claims.

Bias and potential biases also play a role in assessing source credibility. This involves identifying any underlying perspectives, personal or institutional, that may affect the reliability of the information. A biased source may present skewed data or manipulate the facts to support a specific agenda. To avoid falling for biased information, consider searching for opposing views and alternate explanations that challenge the original source’s claims.

In summary, evaluating source credibility requires critical thinking applied to various aspects of the information and its source. Considering factors such as relevance, credibility, trustworthiness, and potential biases enables researchers to confidently select sources that contribute to the accuracy and validity of their work.

The Role of Critical Thinking Skills

Critical thinking skills play a crucial role in evaluating sources for their credibility, relevance, and accuracy. These skills involve the use of logic, analysis, and reflection to ensure that the information gathered from various sources is trustworthy and reliable. By applying critical thinking, individuals can make informed decisions and develop well-founded arguments, both in academic and professional settings.

One aspect of critical thinking involves questioning the information presented by a source. This includes assessing the author’s credentials, the publication date, and the source’s purpose. By considering these factors, individuals can determine if the source is biased, outdated, or unreliable. For example, examining the author’s expertise in the subject matter helps to establish whether the information provided can be trusted.

In addition to questioning the source, critical thinking skills also involve analyzing the evidence and arguments presented. This process requires a careful examination of the logic, consistency, and coherence of the information. By looking for gaps in reasoning or identifying unsupported claims, individuals can assess the strength of the source’s argument and its relevance to their own research or project.

Experience also plays a significant role in developing and applying critical thinking skills. As individuals encounter various sources and engage in different research projects, they can become more adept at identifying trustworthy information. Experience helps refine their ability to discern between credible and unreliable sources, ensuring that the evidence used in their work is accurate and well-founded.

In conclusion, critical thinking skills are vital for evaluating sources and determining their credibility, relevance, and accuracy. By utilizing logic, analysis, questioning, and experience, individuals can ensure that the information they gather is reliable, unbiased, and valuable for their purposes.

Understanding the Purpose and Audience

Evaluating sources using critical thinking involves understanding the purpose and audience of a piece of information. This allows readers to assess the credibility and relevance of a source more effectively.

One of the first steps in evaluating a source is to identify its purpose. The purpose may be to inform, persuade, entertain, or express an opinion. Knowing the purpose behind the content helps readers determine whether the information provided aligns with their own goals and research interests. For example, an academic article seeking to inform would differ in tone and depth from a blog post expressing a personal opinion.

Considering the audience also plays a significant role in critically evaluating sources. Different sources might be aimed at different audiences, such as experts, general readers, or specific demographic groups. Assessing the intended audience assists in determining the suitability of a source for one’s research. A source intended for experts might be more in-depth and technical, while a general audience source could provide a broader overview.

The scope and depth of a source should also be analyzed during the evaluation process. Scope refers to the range of topics covered, whereas depth refers to the level of detail provided. Readers should ensure that the source adequately covers the subject matter they are researching. A source with greater depth and a narrow focus might be more suitable for specialized research, while a broader source could be useful for general understanding.

Tone is an important aspect of a source that can reveal the author’s perspective and potential biases. A neutral tone indicates an objective approach, while passionate or persuasive tones could indicate bias or an attempt to sway readers’ opinions. Recognizing the tone helps readers better understand the author’s intent and the reliability of the information provided.

By confidently assessing the purpose, audience, scope, depth, and tone of a source, readers can better evaluate the credibility and relevance of the information provided. This critical thinking approach supports well-informed research and decision-making.

Evaluating the Quality of Information

Evaluating the quality of information is an essential aspect of critical thinking and information literacy. As researchers, we must be able to determine the credibility and relevance of the sources we use for valid and accurate decision-making. To achieve this, apply consistent standards when evaluating sources, and be aware of your own biases and assumptions when encountering information.

The first step in evaluating the quality of information is to examine its source. Consider factors such as the author’s qualifications, the publication date, and the publisher’s reputation. Sources should be both recent and reputable to ensure that the data and facts presented are accurate and up-to-date.

In addition to the source, the content of the information itself should be scrutinized. Look for well-structured arguments, reliable evidence, and comprehensive data. Information should be easily verifiable, and any claims made by the author should be supported by appropriate facts or data. It’s also crucial to identify any limitations or potential biases present in the information.

Compare the information you’ve found with other sources, looking for consistency and agreement among multiple sources. This process not only helps to corroborate the credibility of the information but also highlights areas where further research may be needed.

Another useful approach to evaluating information quality is the application of information literacy. This involves understanding the purpose of the information, its intended audience, and any potential consequences of using the information. By keeping these factors in mind, you can better assess the suitability of the information for your specific research needs.

In summary, when evaluating the quality of information, be sure to consider factors such as the source’s credibility, the content’s relevance and accuracy, and the application of information literacy. By maintaining a confident, knowledgeable, and neutral approach in your assessment, you can ensure the information you use is of high quality and supports your research effectively.

Determining the Relevance and Value of Sources

Evaluating sources using critical thinking involves assessing their relevance and value to your research topic. Relevance refers to how closely the source’s information aligns with your research question, while value indicates the contribution it makes to your understanding of the topic.

To determine the relevance of a source, first consider whether its content directly addresses your research question or provides information that is applicable to your topic. Analyze the main arguments and conclusions of the source to see if they align with your research goals. Also, take note of any biases or opinions the author may have that could affect the source’s relevance.

In addition, it is essential to assess the value of a source by carefully examining its arguments and the evidence supporting them. A valuable source will present well-reasoned, logical arguments backed by appropriate evidence. Check for any claims that appear to be exaggerated, misleading, or false as these can harm the credibility of the source.

When evaluating the value of sources, it is useful to consider the following factors:

• Authority : Assess the author’s credentials and expertise to determine if they hold the necessary qualifications to speak on the subject matter. Experts in a particular field are likely to provide more valuable and reliable information.
• Accuracy : Ensuring the source contains accurate information is crucial. Verify that the data and facts presented in the source are accurate and compare them with other credible sources, if necessary.
• Timeliness : The currency of the information is another essential factor to consider. In some fields, especially rapidly changing ones, older information may be outdated, and newer sources are more valuable.
• Objectivity : A valuable source should present a balanced perspective on the topic. Be cautious of sources that promote a single viewpoint or are heavily influenced by the author’s personal opinions. Objective sources are more likely to provide value to your research.

By considering these factors while evaluating sources using critical thinking, you can effectively determine their relevance and value, ensuring the quality and credibility of your research.

Investigating the Currency and Timing of Sources

When evaluating sources, it is crucial to investigate the currency and timing of the information presented. This involves assessing whether the content is up-to-date, relevant, and appropriate for the topic being researched. Evaluating the currency of a source helps to determine its overall reliability and credibility for the research.

Firstly, consider the publication or posting date of the information. Determine if it’s recent and whether the content has been revised or updated since it was initially published. A source that is current and up-to-date indicates that the author is actively maintaining the information, which could lead to more reliable conclusions in the research. Keep in mind that the importance of currency may vary depending on the topic and the discipline. In some fields, like technology and medicine, current sources are crucial, while in others, like history or literature, older sources may still be relevant.

To further assess the currency of a source, examine its references and citations. Do they include recent research and publications? Are there any discrepancies between the cited sources and the content of the material being assessed? If the references consist mainly of older publications, consider whether the author has overlooked recent or updated research that could impact their conclusions. In addition, take note of any data or statistics used, ensuring that they come from reputable sources and maintain relevance to the topic at hand.

Another aspect to consider is the agreement among experts in the field. If the majority of experts in the area of research concur on the information presented by the source, this could be an indicator of the source’s currency and reliability. On the other hand, if there seems to be significant disagreement about the content, it might be worth exploring more current sources to see if any new data, research or updates have emerged that could impact the credibility of the information.

In sum, investigating the currency and timing of sources is an essential step in evaluating their validity for a research project. By examining factors such as publication dates, revisions, references, and expert agreement, researchers can ensure that the sources they use contribute to a well-informed, relevant, and current understanding of their topic.

Recognizing Bias and Objectivity

When evaluating sources for credibility, it is essential to recognize bias and objectivity. Bias refers to an inclination or perspective that affects a person’s judgment or evaluation, often leading to distorted or one-sided opinions. On the other hand, objectivity is presenting information in a fair and balanced manner, acknowledging counterarguments and alternative perspectives.

To recognize bias in a source, one must pay close attention to the tone, language, and style of the writing. Biased sources often exhibit strong emotional language, subjective terms, and a lack of evidence to support their claims. Additionally, biased authors may disregard counterarguments or dismiss them without proper consideration.

Objectivity in a source can be identified by the presence of a balanced presentation of information, which acknowledges various perspectives and counterarguments. Objective sources will provide evidence and cite credible sources to support their claims. They maintain a neutral tone and avoid using emotionally charged language.

In order to evaluate sources effectively, one should remain aware of their own biases and assumptions. This can be achieved by considering alternative viewpoints and testing hypotheses against relevant criteria. Applying consistent standards when evaluating sources helps to ensure a fair assessment of the information.

Ultimately, evaluating sources using critical thinking involves recognizing bias and objectivity, while also considering one’s own perspective. By doing so, one can make well-informed decisions based on credible, balanced, and reliable information.

Identifying Potential Errors and Limitations

When evaluating sources using critical thinking, it is crucial to identify potential errors and limitations present in the information provided. This helps ensure the accuracy and reliability of the data. Errors can occur at any point in the research process, while limitations are inherent weaknesses or constraints that affect the findings’ overall validity.

One common error in research is sampling bias, which occurs when the sample is not representative of the whole population. This can lead to skewed conclusions and weaken the overall strength of the research. To avoid this, carefully consider the data collection methods, sample size, and sampling techniques involved in the research.

Another factor to consider is the presence of any logical fallacies or cognitive biases. Errors in reasoning can seriously undermine the credibility of a source. Examples include the ad hominem fallacy, where the focus is on attacking the person rather than the argument, and confirmation bias, where people tend to favor information that confirms their pre-existing beliefs. Be aware of these common fallacies and biases when evaluating arguments.

Furthermore, take note of the methodology used in the research. A study with rigorous methodology, which meticulously controls various factors and variables, has a higher degree of reliability. Conversely, poor methodology can introduce errors and weaken the research’s reliability. When examining the methodology, look for a clear statement of the research question, an explanation of the research design and data collection procedures, and a transparent presentation of results.

Limitations in research are often unavoidable and may affect the study’s generalizability, validity, or reliability. When examining sources, discern the limitations acknowledged by the authors themselves. These may include a small sample size, lack of control over external variables, or potential issues with the data collection method. Identifying these limitations allows for a better understanding of the study’s weaknesses and context.

Lastly, evaluate the relevance of the source to your particular research question or problem. A source may have strong methodology, robust findings, and few errors, but if it does not address the issue you are investigating, it might not contribute meaningfully to your research.

In summary, when using critical thinking to evaluate sources, it is essential to identify potential errors and limitations. This will enable you to assess the credibility, reliability, and overall quality of the information, ensuring that you base your conclusions on sound evidence.

The CRAAP Test for Source Evaluation

The CRAAP Test is a method designed to evaluate sources using critical thinking skills, specifically focusing on five criteria: Currency, Relevance, Authority, Accuracy, and Purpose. By applying these criteria, researchers and readers can determine the credibility of a source and its suitability for their particular needs.

Currency refers to the timeliness of the information. This criterion demands attention to the publication date, any revisions or updates, and whether the source has current or outdated information. Currency is crucial because it ensures that the information used in the research is up-to-date and accurate at the time of use.

Relevance is the degree to which the information relates to the topic being researched. To assess relevance, consider the scope, depth, and target audience of the source. A relevant source should be in alignment with the research question and offer insight or evidence to support the argument being made.

Authority concerns the credibility of the author, organization, or publication responsible for the source. The assessment of authority includes reviewing the author’s credentials, expertise, and affiliation, as well as verifying the reputation of the organization or publication. Established and reputable sources are more likely to produce reliable information.

Accuracy evaluates the validity and reliability of the information in the source. Accuracy can be verified by checking for factual errors, examining the methodology used to collect data, and assessing whether the information is supported by evidence. A source should be free from significant errors and demonstrate that proper research methods were employed.

Purpose is the goal or objective behind the information in the source. Analyzing the purpose helps to identify any potential biases or underlying motives. To evaluate purpose, consider the author’s intent, the target audience, and whether the information is presented objectively or with an ulterior agenda.

Implementing the CRAAP Test as a guideline for source evaluation ensures that the information used in research is credible, relevant, authoritative, accurate, and purposeful. Applying these criteria will strengthen arguments and improve the overall quality of research.

Applying Source Evaluation in Different Contexts

Evaluating sources using critical thinking is not limited to academic research; it plays a vital role in various contexts, such as personal life, college, humanities, and organizations. By applying source evaluation, individuals gain the ability to assess the credibility and relevance of information, leading to informed decisions and well-constructed arguments.

In personal life , individuals often encounter various sources of information, such as news articles, social media, and online resources. Evaluating these sources helps in distinguishing reliable information from misinformation or biased perspectives. For instance, when making major life decisions, such as choosing a career or purchasing a house, individuals must critically assess the credibility of financial advice, job market trends, and real estate listings to make informed choices.

Within the college setting, students must develop essential critical thinking skills to evaluate sources for their academic assignments and research projects. Evaluating sources can significantly impact their grades, as well as their ability to develop strong arguments and contribute to scholarly discussions. Students need to employ research methods that prioritize reliability and relevance when selecting sources, such as peer-reviewed articles, authoritative reports, and primary materials related to their areas of study.

In humanities disciplines, scholars often analyze historical documents, pieces of literature, and other cultural artifacts. These fields require nuanced evaluation methods due to the subjective and interpretive nature of the subjects. Critical thinking enables scholars to consider the context in which a source was produced, assess the intentions and biases of the author, and compare sources with different perspectives to form a comprehensive understanding of the subject matter.

Research methods play a crucial role in evaluating sources, especially in academic and professional settings. A systematic approach to source evaluation, such as following established criteria like the CRAAP test (Currency, Relevance, Authority, Accuracy, and Purpose), ensures that the chosen sources align with research objectives and contribute to robust arguments. Additionally, researchers must evaluate the methodologies used in the sources to determine the quality and reliability of the research findings.

In an organization , source evaluation holds significance for decision-making processes, innovation, and strategic planning. Organizations rely on accurate and reliable data to make well-informed decisions that can impact their growth and success. Business professionals must critically analyze sources like industry reports, market trends, financial data, and other relevant materials to develop effective strategies grounded in verifiable information.

In summary, applying source evaluation using critical thinking is crucial in various contexts for making informed decisions, engaging in scholarly discussions, and developing well-grounded arguments. By employing appropriate research methods, evaluating sources based on their credibility and relevance, and considering context-specific nuances, individuals can effectively assess and utilize information in their personal lives, academia, and professional settings.

Consequences of Misleading Information

Misleading information can have significant consequences in various aspects of society. When people encounter false information or propaganda, they may unknowingly make decisions based on inaccurate or incomplete data.

One consequence of misleading information is that it can perpetuate false beliefs and can reinforce an individual’s existing views. As a result, people might take actions based on these beliefs, which could lead to unintended and potentially harmful outcomes. For example, misinformation regarding medical treatments might cause people to ignore scientific advice, leading to negative health consequences.

Misleading information can also distort public discourse and hinder society’s ability to address pressing issues effectively. When misinformation is used to promote a hidden agenda, people may be swayed by emotional appeals or other non-rational factors, which can exacerbate existing divisions and generate conflicts.

In some cases, misleading information can serve as a tool for political manipulation. When political actors use false or distorted information to shape public opinion, they can gain power or maintain control. This can threaten democratic processes, making it more challenging for citizens to hold their representatives accountable.

To mitigate the consequences of misleading information, it is essential to apply critical thinking skills when evaluating sources. By considering factors such as credibility, accuracy, and potential biases, individuals can distinguish between reliable and untrustworthy information, reducing the impact of hidden agendas or false claims.

Evaluating sources is an essential aspect of critical thinking that helps to ensure the secure foundation of knowledge. Through a rigorous evaluation process, the value of information can be assessed accurately, leading to better decision making and a higher quality of work. By applying the principles of critical thinking, individuals can gain a deeper understanding of the subject matter and develop a well-rounded perspective based on reliable sources.

Various methods can assist in evaluating the credibility of sources, such as the CRAAP test . This acronym represents Currency, Relevance, Authority, Accuracy, and Purpose as discussed here . By considering each of these factors, individuals can effectively distinguish between trustworthy and unreliable sources, thereby improving their overall knowledge and experience when conducting research.

The importance of consistent evaluation standards cannot be overstated. Recognizing personal biases and assumptions during the process bolsters the value of critical thinking and ensures a more balanced perspective, leading to stronger, more robust arguments. By remaining vigilant and applying these principles consistently, the quality of the information consumed is significantly enhanced.

In conclusion, honing one’s critical thinking skills and evaluating sources rigorously enables individuals to achieve a heightened sense of knowledge and understanding. By carefully considering the quality, relevance, and authority of each source encountered, a more reliable foundation of information is established, leading to better decision making and ultimately enhancing the overall quality of work and personal experience.

Critical thinking skills are crucial for AI.

AI, particularly generative AI, is having an immediate and dramatic impact on our lives, both personally and professionally. AI enables everyone to become better writers, content creators, coders, and artists. Interestingly, to derive effective value from AI systems, we must also develop our "soft skills”, of which critical thinking becomes one of the most important.

Just a few years ago, to get real benefit from AI, you needed to build and train AI systems which required “hard” skills such as math, programming, or data engineering skills. Now, because of generative AI, you no longer need to be an expert in statistics & probability, calculus, or linear algebra to get value from using Generative AI. You also don’t need knowledge of different algorithms & modeling skills. Instead, you need to use soft skills such as communication, curiosity, problem solving, adaptability, and critical thinking.

Why Critical Thinking is Crucial for AI

There’s no doubt that in today's fast-paced business environment, workers will need to use AI tools to stay ahead in the market. While AI systems will let anyone get a basic grasp of hard skills, the soft skills are proving to be the most important to get value from AI systems. In particular, the soft skill of critical thinking is proving indispensable. Put simply, critical thinking is the ability to get a solid, reliable, and as truthful as possible understanding of information, and then use that understanding to make sound decisions based on that knowledge. This means scrutinizing information, questioning assumptions, and ensuring that conclusions are supported by solid evidence.

When it comes to using generative AI systems, being able to observe, analyze, discern, and ask the right questions is what not only allows you to get the required results from the AI, but also to determine if the outputs are credible, lack bias, and truthful. Critical thinking approaches provide the necessary mental tools to iteratively refine prompts and hone in to get more effective results. Trying different approaches using thinking skills leads to clearer, more accurate results. The ability to analyze complex requirements helps in designing effective prompts and assessing the quality of AI-generated responses.

How To Develop Critical Thinking Skills

Critical thinking skills will only become more important in our AI-driven organizations. This means that people of all ages will need to make sure to develop and use critical thinking skills to be able to stay ahead of the pack. A key approach to develop and refine critical thinking skills is to always approach interactions with AI systems with a healthy dose of skepticism, and question assumptions, especially your own. Ask yourself whether the information going into and out of AI systems make sense and what assumptions are being made. Look for evidence to support or refute these assumptions.

Additionally, you’ll want to seek evidence. It goes without saying that especially in an AI-generated world, you can’t take what you see, hear, or read at face value. Large language models are known to hallucinate, or confidently provide you with the wrong information. Verify the sources of your information and ensure that your conclusions are backed by solid proof, research, or findings, and dive deeper to find supporting evidence.

Critical thinking also requires you to be aware of potential informational and data biases. Those biases could be represented in your thinking, data, analyses, outputs of LLM systems, or the way in which you utilize or scrutinize AI outputs. Work to observe and identify patterns and trends in data. This involves not just looking at the data, but understanding the context and relationships between different variables.

Key Benefits Of Critical Thinking in an AI-Centric World

As you continue to work on your critical thinking skills, you’ll see many key benefits, especially as more people make use of AI to augment or assist their work. Professionals are often required to make decisions based on various data points and pieces of information. Critical thinking enables you to sift through the mountains of AI-generated information, identify what is relevant, and then make decisions based on accurate interpretations. This is especially the case with generative AI. Without critical thinking, there is a risk of making decisions based on incomplete or incorrect information, which can lead to erroneous, suboptimal, or misleading results.

A key to critical thinking is problem solving skills. Critical thinking helps professionals approach problems systematically, considering all possible solutions and their implications before making decisions. This thorough approach reduces the likelihood of overlooking important factors and increases the chances of finding effective solutions. It also helps you become a better prompt engineer as you’ll not stop until you get a satisfactory response. You are able to evaluate complex situations to make informed decisions. This analytical ability helps in designing effective prompts and assessing the quality of AI-generated responses.

Setting Yourself Apart With Critical Thinking

Individuals who excel in critical thinking will stand out when it comes to the use of AI. These individuals can navigate complex information landscapes, create better results and responses from LLMs, make better informed decisions, iterate more effectively to get desired outcomes, and be more effective when it comes to communicating and sharing results.

The ability to critically evaluate and interpret information is a strategic advantage for those who are working with AI systems. As AI becomes an increasing part of our every day business processes, tools, and interactions, those with strong critical thinking abilities will be better equipped to harness AI’s full potential, driving innovation, better insights, and answers.

Whether you drive an electric car or are considering making the switch, you've probably been drawn into a discussion about whether they are really better for the climate.

Electric cars are key to the world reducing emissions, with transport accounting for almost 20 per cent and rising, so you probably haven't had that debate for the last time.

To save you from your next barbecue encounter, we have turned to the EV Council, which has crunched the numbers for you.

We're comparing an electric car and a traditional petrol one and looking at the life-cycle emissions — that is, all the emissions produced from cradle to grave.

For both types of car, these are the key stages where emissions are produced:

• manufacturing of the car,
• production of the battery, especially for electric cars
• running the cars over their life-cycle, either on petrol or electricity
• disposal and recycling of the vehicle at the end of its life, including batteries

We'll also compare electric cars in different states because each state uses different amounts of fossil fuels for electricity, which affects how "clean" the car is.

To compare cars, we've chosen an average medium SUV, the sort of car you commonly see on Australian roads.

Some examples of a medium SUV are the electric Tesla Model Y, Toyota's RAV4 and the Mazda CX-5 on the petrol side.

So, buckle up and let's go.

Let's start at when the car is made

Manufacturing covers the production of the raw materials in the car's metal body, interiors, tyres, seating, the whole bundle. At this first stage, all these cars come out with similar emissions profiles.

… adding batteries for EVs

Battery production is the stage where we start to see a split between petrol and electric cars.

Electric vehicles (EV) are powered by batteries, so their batteries are significantly larger and heavier, and use more critical minerals. Our electric SUV also needs a bigger battery than a small hatchback.

It's important to note that this is about life-cycle emissions, so we aren't evaluating other environmental or human rights impacts from battery production for EVs, and we're also not critiquing the oil industry in those areas for petrol cars. That barbecue debate is for another day.

Batteries produced in China have higher emissions than those produced in Europe, and as most Australian electric cars currently have Chinese-made batteries, that's what's used here.

Climate experts and even the latest Intergovernmental Panel on Climate Change expect these figures to drop as more renewable energy is used in the coming years to make the batteries.

"So the energy needed to produce batteries is decarbonised, and therefore has lower emissions," according to University of Technology Sydney transport researcher, Robin Smit.

So at this point, before the cars hit the road, electric cars have more embedded emissions.

But that all changes when you start driving …

Taking our cars on the road

It won't shock you to find out that most of a car's lifetime emissions come from powering it to drive.

"The fuel energy cycle is normally the most important part of the life-cycle assessment [and] that includes on-road driving, the maintenance, and of course, the production of the energy," Professor Smit said.

The Australian Bureau of Statistics (ABS) estimates the average Australian car drives about 12,600 kilometres a year, or 189,000 over its lifetime, so that is what's used in this modelling.

Petrol cars are dirty. That's a fact. Combustion cars are powered by burning petrol, which releases emissions into the atmosphere and is — pardon the pun — a major climate change driver. These are referred to as "tailpipe emissions".

The petrol SUV here is up against an electric SUV charged on the national grid, which has a mix of fossil fuels and renewables.

Our petrol SUV produces almost 46 tonnes of carbon over its lifetime on the road.

These figures also factor in the emissions coming from refining and transporting the fuel.

"When you look at fossil fuels, they need to be extracted, processed, and then transported to service stations, for example, to make them available. So there's a greenhouse gas emission costs associated with that," Professor Smit said.

The estimated petrol used here is 8.3 litres for 100km and comes from the Worldwide Harmonised Light Vehicle Test Procedure (WLTP). These figures are almost always lower than real-world petrol use.

So, a lot of energy is burnt to move petrol cars, but most of it is wasted.

"They are not efficient, about 70 to 80 per cent of the energy is wasted in heat. So you only use 20 to 30 per cent of the energy into fuels for actually driving around," Professor Smit said.

What's more, Australians typically drive heavier cars than other countries, especially in Europe. Heavier cars require more fuel to move them, resulting in higher emissions.

This all means that petrol cars start producing significantly more emissions during their use, leaving electric cars in the dust.

Let's look at a different view of our two cars as we drive them for 15 years or 189,000km. Petrol cars are displayed in the blue line, and electric cars in red .

Electric cars are powered by electricity (obviously!) but how that electricity is created makes a huge difference to the overall emissions profile of EVs.

You can see emissions for the petrol car   rise while the electric car's life-cycle emissions curve is flattening. That's because the composition of our electricity grid is rapidly changing and more renewables are coming online.

To account for that, this modelling from the EV Council uses the scenario mapped out by the Australian Energy Market Operator (AEMO) which predicts the rate of new renewables coming into the grid and fossil fuel plants being decommissioned. That is, by 2030, the same electric car will be producing lower emissions because it will be charged with more renewable power.

So this is for Australia as a whole, but where you live can also have a big impact on how much cleaner an EV is.

Some Australian states already have mostly renewable energy powering their grids, while others still have lots of fossil fuels.

A car that's charged off a grid with lots of fossil fuels produces much higher emissions than a car charged somewhere with mostly renewable energy.

Let's look at our electric SUV in Western Australia, where in 2022 more than 83 per cent of electricity came from fossil fuels, mostly gas.

Now this is what our SUV's emissions look like in Tasmania (shown in the green line) , which powers almost its entire electricity network on hydro.

It's the same in South Australia, which has lots of wind and solar energy in the grid. You can see here that no matter where the EV is, it saves tonnes of emissions overall compared to a petrol SUV.

This highlights the huge opportunity to reduce transport emissions with electric cars.

The cleaner the grid, the cleaner the electric car.

What about cars charged on rooftop solar?

More than 3 million Australian homes have rooftop solar and, according to a 2021 survey, most EV owners plug into their own set-up.

A car that's charged with rooftop solar produces even lower emissions over its lifetime.

"When you use solar panels, they basically have very small-to-negligible emissions," Professor Smit noted.

Less than a tonne of carbon over all those kilometres!

Now, it's time to say goodbye to our cars and send them to the car afterlife …

Getting rid of our cars

According to Professor Smit, the greenhouse gas emissions from taking cars off the road are small compared to the overall driving life of a car.

What's more, most of the materials in a car can be recycled, so this offsets some of the emissions from the production of the car at the start of the cycle.

To complete our emission profile, let's add the emissions for the disposal of our cars.

There's a lot of potential for improvements here too.

It takes a lot of grunt to power a car, and when a battery can no longer do that and comes out of an electric car, it still holds a lot of value and charging potential.

It can be used as a backup household battery, for example. Some car companies like Tesla are already using old car batteries to power their factories.

It's estimated this second life for EV batteries could cut the carbon footprint of battery production by half.

At the finish line

Overall, every electric car will produce fewer emissions than its petrol equivalent, no matter where they are charged.

Even with an electricity grid that still uses some fossil fuels, electric cars have much lower overall carbon emissions, and that will continue to drop as the electricity gets greener.

And remember, this example uses SUVs, so lighter electric cars like hatchbacks have even lower emissions.

Hang on, what about hybrids?

Put simply, hybrids are complicated.

Plug-in hybrids can be run off either petrol or from a battery that's plugged in and charged. Therefore, the life-cycle emissions from a plug-in hybrid depend on the region where it gets charged but also on how diligent the driver is with charging. Remember, it can also run on petrol.

The European Union's Environment Agency recently found that emissions from plug-in hybrids were 3.5 times higher than reported.

It concluded that hybrids "are charged and driven in electric mode much less than how they were expected to be used".

Where we get our figures from

These figures come from the Electric Vehicle Council, which based its life-cycle emissions calculator on modelling from the European organisation Transport & Environment .

We got Professor Smit to look over the EV Council's modelling and he said while it was generous to petrol cars, it provided a good way to compare life-cycle emissions.

The inputs for petrol use are based on the WLTP . As mentioned in the story, this is likely to underestimate real-world petrol usage.

The modelling uses data for a Nickel-Mangenese-Cobalt NMC li-ion battery produced in China, as that's the most common type of battery in the Australian EV market.

It calculates 105kg CO2/KWh  for the carbon produced from battery production .

This same study found that "producing batteries with photovoltaic electricity instead of Chinese coal-based electricity decreases climate impacts of battery production by 69 per cent". Considering this estimate would reduce the emissions calculation in the point we make about battery production.

For a medium electric SUV, the energy used is 17.3 KWh/100km and a battery size of 70.2 KWh average for cars available in that category.

The emissions factors for energy sources are based on data from the Intergovernmental Panel for Climate Change  here. 

To model the rate of renewables coming into the grid, the EV Council used the step-change scenario from the AEMO .

Statements about the composition of the electricity grids in different states come from 2022 numbers from the Department of Climate Change, Energy, the Environment and Water.

The estimate of recycling emissions comes from a study by Transport & Environment .
