Become a better critical thinker with these 7 critical thinking exercises

Critical thinking is a skill you can use in any situation. Whether you're a student, entrepreneur, or business executive, critical thinking can help you make better decisions and solve problems.

But learning critical thinking skills isn't always an easy task. Many tools, techniques, and strategies are available, and choosing the right one can be challenging. Vague suggestions on the internet like "read more" aren't very helpful, and elaborate business examples don’t apply to many of us.

As average problem-solvers, we need actionable thinking exercises to improve our critical thinking skills and enhance our thinking processes. Regularly performing exercises that specifically stretch our decision-making and reasoning skills is the most effective method of improving our thinking abilities.

This article will explore several exercises that will help you develop critical thinking skills. Whether you are preparing for an exam, making an influential decision for your business, or going about your daily life, these fun activities can build your reasoning skills and creative problem-solving abilities.

Boost your logical thinking skills and start practicing a critical mindset with these 10 critical thinking exercises.

A Quick Look at Critical Thinking

As a thoughtful learner, you likely already understand the basics of critical thinking, but here's a quick refresher.

Critical thinking involves analyzing problems or issues objectively and rationally. Critical thinkers are able to understand their own biases and assumptions, as well as those of others. They’re also able to see the world from a different point of view and understand how their experiences impact their thinking.

Developing critical thinking skills is essential because it allows us to see things from multiple perspectives, identify biases and errors in reasoning, and be open to possible solutions. Making informed decisions is easier when we have a better understanding of the world around us.

Why We Need to Practice Critical Thinking

We aren't born with critical thinking skills, and they don’t naturally develop beyond survival-level thinking. To master critical thinking, we must practice it and develop it over time.

However, learning to think critically isn't as easy as learning to ride a bicycle. There aren't any step-by-step procedures to follow or supportive guides to fall back on, and it is not taught in public schools consistently or reliably. To ensure students' success, teachers must know higher-order thinking skills (HOTS) and how to teach them, research says.

Unfortunately, although teachers understand the importance of HOTS and attempt to teach it, studies show that their capacity to measure students' HOTS is low. Educator and author Dr. Kulvarn Atwal says, "It seems that we are becoming successful at producing students who are able to jump through hoops and pass tests."

As critical thinking skills become more important in higher grades, some students find it challenging to understand the concept of critical thinking. To develop necessary thinking skills, we must set aside our assumptions and beliefs. This allows us to explore and question topics from a "blank page" point of view and distinguish fact from opinion.

7 Critical Thinking Exercises To Improve Your Critical Thinking Skills

The good news is that by assessing, analyzing, and evaluating our thought processes, we can improve our skills. Critical thinking exercises are key to this improvement. Our critical thinking builds and improves with regular practice, just like a muscle that gets stronger with use.

If you want to become a better critical thinker , here are some critical thinking exercises to try:

Exercise #1: The Ladder of Inference

You can exercise your critical thinking skills by using the Ladder of Inference model . This thinking model was developed by renowned organizational psychologist Chris Argyris. Each rung on the ladder of inference represents a step you take to arrive at your conclusions.

The decision-making process starts when we are faced with a problem or situation. As soon as we observe something problematic or important, we presume what is causing it, and then we use that assumption to draw conclusions. Based on those conclusions, we take action.

For example, say you're at a party and see a friend across the room. You catch their eye and wave, but they turn and walk away. Using the ladder, you might climb the rungs as follows:

• Observe that your friend walked away.
• Select a few details of the situation, including your wave and your assumption that they saw you.
• Meaning is attached based on the environment, making you think your friend must have other people to talk to at the party.
• Assumptions are made based on that meaning, assuming that means your friend doesn’t like you as much as them.
• Conclusions are drawn from the assumption, and you determine that your friend must be mad at you or doesn't want you to be at the party.
• Beliefs are formed, making you think you're not welcome.
• Action is taken, and you leave the party.

In this example, you started with a situation (someone walking away at a crowded party) and made a series of inferences to arrive at a conclusion (that the person is mad at you and doesn't want you there).

The Ladder of Inference can be a helpful tool to frame your thinking because it encourages you to examine each step of your thought process and avoid jumping to conclusions. It's easy to make assumptions without realizing it, as in this scene. Perhaps your friend never even saw you wave from across the crowded room.

Exercise #2: The Five Whys

The "Five Whys" technique is an analytical skill that can help you uncover the source of a problem. The activity was created by Sakichi Toyoda, the founder of Toyota, and consists of repeatedly asking “why?” when a problem is encountered to determine its root cause.

This exercise can be difficult because knowing if you've discovered the source of your problem is challenging. The "five" in "Five Whys" is just a guideline — you may need to ask more. When you can't ask anything else, and your response is related to the original issue, you've probably arrived at the end.

Even if you need several rounds of questioning, just keep going. The important part that helps you practice critical thinking is the process of asking "why?" and uncovering the deeper issues affecting the situation.

For instance, say you're trying to figure out why your computer keeps crashing.

• You ask " why ," and the answer is that there's a software problem.
• Why? Because the computer keeps running out of memory.
• Why? Because too many programs are running at the same time.
• Why? Because too many browser tabs are open .
• Why? Because multitasking is fragmenting your focus, you're doing too many things at once.

In this example, working through the "why's" revealed the underlying cause. As a result, you can find the best solution, which is concentrating on just one thing at a time.

Exercise #3: Inversion

Inversion is another critical thinking exercise that you can use in any situation. Inversion is sort of like taking on the role of the devil's advocate. In this exercise, adopt the opposite view of whatever issue you're exploring and consider the potential arguments for that side. This will help broaden your critical thinking skills and enable you to see other perspectives on a situation or topic more clearly.

For example, let's say you're thinking about starting your own business. Using inversion, you would explore all of the potential arguments for why starting your own business is bad. This might include concerns like:

• You could end up in debt.
• The business might fail.
• It's a lot of work.
• You might not have time for anything else.

By exploring these potentially adverse outcomes, you can identify the potential risks involved in starting your own business and make a more sound decision. You might realize that now is not the right time for you to become an entrepreneur. And if you do start the company, you'll be better prepared to deal with the issues you identified when they occur.

Exercise #4: Argument Mapping

Argument mapping can be a beneficial exercise for enhancing critical thinking skills. Like mind mapping, argument mapping is a method of visually representing an argument's structure. It helps analyze and evaluate ideas as well as develop new ones.

In critical thinking textbooks, argument diagramming is often presented to introduce students to argument constructions. It can be an effective way to build mental templates or schema for argument structures, which researchers think may make critical evaluation easier .

Argument maps typically include the following:

• Conclusion: What is being argued for or against
• Premises: The reasons given to support the conclusion
• Inferences: The connections made between the premises and conclusion

The argument map should be as clear and concise as possible, with a single word or phrase representing each element. This will help you make connections more easily. After the map is completed, you can use it to identify any weak points in the argument. If any areas aren't well-supported, additional premises can be added.

Argument mapping can be applied to any situation that requires critical thinking skills. The more time you take to map out an argument, the better you'll understand how the pieces fit together. Ultimately, this will help you think more creatively and critically, and make more informed decisions.

Exercise #5: Opinion vs. Fact

Critical thinking activities that focus on opinions and facts are particularly valuable and relevant new learning opportunities. Our constantly-connected world makes it easy to confuse opinions and facts , especially with sensationalist news articles and click-bait headlines.

How can you tell a fact from an opinion? Facts are generally objective and established, whereas opinions are subjective and unproven. For example, "the cloud is in the air" is a fact. "That dress looks good on you" is an opinion.

Practice your critical thinking skills by reading or listening to the news. See if you can identify when someone is stating an opinion rather than a fact. Ask yourself the following questions:

• Who is saying what? What reasons might be behind their statements?
• Does the claim make sense? Who would disagree with it and why?
• How can you tell if the data is reliable? Can it be fact-checked? Has it been shared by other credible publishers?
• How do you know whether or not the presenter is biased? What kind of language is being used?

This powerful exercise can train your mind to start asking questions whenever presented with a new claim. This will help you think critically about the information you're taking in and question what you're hearing before accepting it as truth.

Exercise #6: Autonomy of an Object

In her book " The Critical Thinking Tool Kit ," Dr. Marlene Caroselli describes a critical thinking exercise called "Living Problems, Lively Solutions." This exercise uses the autonomy of an object as a problem-solving tool to find a possible solution.

To do this, you'll personify your problem and place it in another context — a different time or place. This allows you to uncover unique solutions to the problem that might be tied to your mental associations with that setting.

For example, if your problem is poor time management , you might personify the issue as a thief of your time. The idea of a thief could make you think of jail, which might prompt thoughts of locking up specific distractions in your life. The idea of jail could also make you think of guards and lead you to the possible solution of checking in with an accountability buddy who can make sure you're sticking to your schedule.

The autonomy-of-object technique works because it stimulates thoughts you wouldn’t have considered without the particular context in which you place the problem.

Exercise #7: The Six Thinking Hats

Designed by Edward de Bono, the Six Thinking Hats is a critical thinking exercise that was created as a tool for groups to use when exploring different perspectives on an issue. When people use other thinking processes, meetings can become challenging rather than beneficial.

To help teams work more productively and mindfully, de Bono suggests dividing up different styles of thinking into six categories, represented as hats:

• The white hat is objective and focuses on facts and logic
• The red hat is intuitive, focusing on emotion and instinct
• The black hat is cautious and predicts negative outcomes
• The yellow hat is optimistic and encourages positive outcomes
• The green hat is creative, with numerous ideas and little criticism
• The blue hat is the control hat used for management and organization

With each team member wearing a different hat, a group can examine an issue or problem from many different angles, preventing one viewpoint (or individual) from dominating the meeting or discussion. This means that decisions and solutions reached using the Six Thinking Hats approach will likely be more robust and effective, and everyone’s creative thinking skills will benefit.

Critical thinking is a skill that students develop gradually as they progress in school. While the skill becomes more important in higher grades, some students find it difficult to understand the concept of critical thinking .

The reason critical thinking can be difficult to grasp is because it requires students to set aside assumptions and beliefs to learn to think without bias or judgment.

Critical thinking involves suspending your beliefs to explore and question topics from a "blank page" point of view. It also involves the ability to distinguish fact from opinion when exploring a topic.

These exercises are designed to help develop critical thinking skills.

Critical Thinking Exercise 1: Tour Guide for an Alien

This exercise provides an opportunity to think outside your normal way of thinking.

Pretend that you have been assigned the task of conducting a tour for aliens who are visiting the earth and observing human life. You're riding along in a blimp, viewing the landscape below, and you float over a professional baseball stadium. One of the aliens looks down and is very confused by what he sees. You explain that there is a game going on and he asks several important questions.

• What is a game? 
• Why are there no female players?
• Why do people get so excited about watching other people play games?
• What is a team?
• Why can't the people in the seats go down on the field and join in?

If you try to answer these questions fully, it will quickly become apparent that we carry around certain assumptions and values. We support a certain team, for instance, because it makes us feel like we're a part of a community. This sense of community is a value that matters to some people more than others.

Furthermore, when trying to explain team sports to an alien, you have to explain the value we place on winning and losing.

When you think like an alien tour guide, you are forced to take a deeper look at the things we do and things we value. Sometimes they don't sound logical from the outside looking in.

Critical Thinking Exercise 2: Fact or Opinion

Do you think you know the difference between fact and opinion? It's not always easy to discern. When you visit websites, do you believe everything you read? The abundance of available information makes it more important than ever for students to develop critical thinking skills. Additionally, it's an important reminder that you must use trustworthy sources in your school work.

If you don't learn the difference between fact and opinion, you may end up reading and watching things that continue to reinforce beliefs and assumptions you already own.

For this exercise, read each statement and try to determine whether it sounds like a fact or an opinion. This can be completed alone or with a study partner .

• My mom is the best mom on earth.
• My dad is taller than your dad.
• My telephone number is difficult to memorize.
• The deepest part of the ocean is 35,813 feet deep.
• Dogs make better pets than turtles.
• Smoking is bad for your health.
• Eighty-five percent of all cases of lung cancer in the U.S. are caused by smoking.
• If you flatten and stretch out a Slinky toy it will be 87 feet long.
• Slinky toys are fun.
• One out of every one hundred American citizens is color blind.
• Two out of ten American citizens are boring.

You will probably find some of the statements easy to judge but other statements difficult. If you can effectively debate the truthfulness of a statement with your partner, then it's most likely an opinion.

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.

What is Critical Thinking?

Critical thinking is the ability to think clearly and rationally, understanding the logical connection between ideas.  Critical thinking has been the subject of much debate and thought since the time of early Greek philosophers such as Plato and Socrates and has continued to be a subject of discussion into the modern age, for example the ability to recognise fake news .

Critical thinking might be described as the ability to engage in reflective and independent thinking.

In essence, critical thinking requires you to use your ability to reason. It is about being an active learner rather than a passive recipient of information.

Critical thinkers rigorously question ideas and assumptions rather than accepting them at face value. They will always seek to determine whether the ideas, arguments and findings represent the entire picture and are open to finding that they do not.

Critical thinkers will identify, analyse and solve problems systematically rather than by intuition or instinct.

Someone with critical thinking skills can:

Understand the links between ideas.

Determine the importance and relevance of arguments and ideas.

Recognise, build and appraise arguments.

Identify inconsistencies and errors in reasoning.

Approach problems in a consistent and systematic way.

Reflect on the justification of their own assumptions, beliefs and values.

Critical thinking is thinking about things in certain ways so as to arrive at the best possible solution in the circumstances that the thinker is aware of. In more everyday language, it is a way of thinking about whatever is presently occupying your mind so that you come to the best possible conclusion.

Critical Thinking is:

A way of thinking about particular things at a particular time; it is not the accumulation of facts and knowledge or something that you can learn once and then use in that form forever, such as the nine times table you learn and use in school.

The Skills We Need for Critical Thinking

The skills that we need in order to be able to think critically are varied and include observation, analysis, interpretation, reflection, evaluation, inference, explanation, problem solving, and decision making.

Specifically we need to be able to:

Think about a topic or issue in an objective and critical way.

Identify the different arguments there are in relation to a particular issue.

Evaluate a point of view to determine how strong or valid it is.

Recognise any weaknesses or negative points that there are in the evidence or argument.

Notice what implications there might be behind a statement or argument.

Provide structured reasoning and support for an argument that we wish to make.

The Critical Thinking Process

You should be aware that none of us think critically all the time.

Sometimes we think in almost any way but critically, for example when our self-control is affected by anger, grief or joy or when we are feeling just plain ‘bloody minded’.

On the other hand, the good news is that, since our critical thinking ability varies according to our current mindset, most of the time we can learn to improve our critical thinking ability by developing certain routine activities and applying them to all problems that present themselves.

Once you understand the theory of critical thinking, improving your critical thinking skills takes persistence and practice.

Try this simple exercise to help you to start thinking critically.

Think of something that someone has recently told you. Then ask yourself the following questions:

Who said it?

Someone you know? Someone in a position of authority or power? Does it matter who told you this?

What did they say?

Did they give facts or opinions? Did they provide all the facts? Did they leave anything out?

Where did they say it?

Was it in public or in private? Did other people have a chance to respond an provide an alternative account?

When did they say it?

Was it before, during or after an important event? Is timing important?

Why did they say it?

Did they explain the reasoning behind their opinion? Were they trying to make someone look good or bad?

How did they say it?

Were they happy or sad, angry or indifferent? Did they write it or say it? Could you understand what was said?

What are you Aiming to Achieve?

One of the most important aspects of critical thinking is to decide what you are aiming to achieve and then make a decision based on a range of possibilities.

Once you have clarified that aim for yourself you should use it as the starting point in all future situations requiring thought and, possibly, further decision making. Where needed, make your workmates, family or those around you aware of your intention to pursue this goal. You must then discipline yourself to keep on track until changing circumstances mean you have to revisit the start of the decision making process.

However, there are things that get in the way of simple decision making. We all carry with us a range of likes and dislikes, learnt behaviours and personal preferences developed throughout our lives; they are the hallmarks of being human. A major contribution to ensuring we think critically is to be aware of these personal characteristics, preferences and biases and make allowance for them when considering possible next steps, whether they are at the pre-action consideration stage or as part of a rethink caused by unexpected or unforeseen impediments to continued progress.

The more clearly we are aware of ourselves, our strengths and weaknesses, the more likely our critical thinking will be productive.

The Benefit of Foresight

Perhaps the most important element of thinking critically is foresight.

Almost all decisions we make and implement don’t prove disastrous if we find reasons to abandon them. However, our decision making will be infinitely better and more likely to lead to success if, when we reach a tentative conclusion, we pause and consider the impact on the people and activities around us.

The elements needing consideration are generally numerous and varied. In many cases, consideration of one element from a different perspective will reveal potential dangers in pursuing our decision.

For instance, moving a business activity to a new location may improve potential output considerably but it may also lead to the loss of skilled workers if the distance moved is too great. Which of these is the more important consideration? Is there some way of lessening the conflict?

These are the sort of problems that may arise from incomplete critical thinking, a demonstration perhaps of the critical importance of good critical thinking.

In Summary:

Critical thinking is aimed at achieving the best possible outcomes in any situation. In order to achieve this it must involve gathering and evaluating information from as many different sources possible.

Critical thinking requires a clear, often uncomfortable, assessment of your personal strengths, weaknesses and preferences and their possible impact on decisions you may make.

Critical thinking requires the development and use of foresight as far as this is possible. As Doris Day sang, “the future’s not ours to see”.

Implementing the decisions made arising from critical thinking must take into account an assessment of possible outcomes and ways of avoiding potentially negative outcomes, or at least lessening their impact.

• Critical thinking involves reviewing the results of the application of decisions made and implementing change where possible.

It might be thought that we are overextending our demands on critical thinking in expecting that it can help to construct focused meaning rather than examining the information given and the knowledge we have acquired to see if we can, if necessary, construct a meaning that will be acceptable and useful.

After all, almost no information we have available to us, either externally or internally, carries any guarantee of its life or appropriateness.  Neat step-by-step instructions may provide some sort of trellis on which our basic understanding of critical thinking can blossom but it doesn’t and cannot provide any assurance of certainty, utility or longevity.

What Is Critical Thinking? | Definition & Examples

Published on May 30, 2022 by Eoghan Ryan . Revised on May 31, 2023.

Critical thinking is the ability to effectively analyze information and form a judgment .

To think critically, you must be aware of your own biases and assumptions when encountering information, and apply consistent standards when evaluating sources .

Critical thinking skills help you to:

• Identify credible sources
• Evaluate and respond to arguments
• Assess alternative viewpoints
• Test hypotheses against relevant criteria

Why is critical thinking important, critical thinking examples, how to think critically, other interesting articles, frequently asked questions about critical thinking.

Critical thinking is important for making judgments about sources of information and forming your own arguments. It emphasizes a rational, objective, and self-aware approach that can help you to identify credible sources and strengthen your conclusions.

Critical thinking is important in all disciplines and throughout all stages of the research process . The types of evidence used in the sciences and in the humanities may differ, but critical thinking skills are relevant to both.

In academic writing , critical thinking can help you to determine whether a source:

• Is free from research bias
• Provides evidence to support its research findings
• Considers alternative viewpoints

Outside of academia, critical thinking goes hand in hand with information literacy to help you form opinions rationally and engage independently and critically with popular media.

• Missing reference entries

Critical thinking can help you to identify reliable sources of information that you can cite in your research paper . It can also guide your own research methods and inform your own arguments.

Outside of academia, critical thinking can help you to be aware of both your own and others’ biases and assumptions.

Academic examples

However, when you compare the findings of the study with other current research, you determine that the results seem improbable. You analyze the paper again, consulting the sources it cites.

You notice that the research was funded by the pharmaceutical company that created the treatment. Because of this, you view its results skeptically and determine that more independent research is necessary to confirm or refute them. Example: Poor critical thinking in an academic context You’re researching a paper on the impact wireless technology has had on developing countries that previously did not have large-scale communications infrastructure. You read an article that seems to confirm your hypothesis: the impact is mainly positive. Rather than evaluating the research methodology, you accept the findings uncritically.

Nonacademic examples

However, you decide to compare this review article with consumer reviews on a different site. You find that these reviews are not as positive. Some customers have had problems installing the alarm, and some have noted that it activates for no apparent reason.

You revisit the original review article. You notice that the words “sponsored content” appear in small print under the article title. Based on this, you conclude that the review is advertising and is therefore not an unbiased source. Example: Poor critical thinking in a nonacademic context You support a candidate in an upcoming election. You visit an online news site affiliated with their political party and read an article that criticizes their opponent. The article claims that the opponent is inexperienced in politics. You accept this without evidence, because it fits your preconceptions about the opponent.

There is no single way to think critically. How you engage with information will depend on the type of source you’re using and the information you need.

However, you can engage with sources in a systematic and critical way by asking certain questions when you encounter information. Like the CRAAP test , these questions focus on the currency , relevance , authority , accuracy , and purpose of a source of information.

When encountering information, ask:

• Who is the author? Are they an expert in their field?
• What do they say? Is their argument clear? Can you summarize it?
• When did they say this? Is the source current?
• Where is the information published? Is it an academic article? Is it peer-reviewed ?
• Why did the author publish it? What is their motivation?
• How do they make their argument? Is it backed up by evidence? Does it rely on opinion, speculation, or appeals to emotion ? Do they address alternative arguments?

Critical thinking also involves being aware of your own biases, not only those of others. When you make an argument or draw your own conclusions, you can ask similar questions about your own writing:

• Am I only considering evidence that supports my preconceptions?
• Is my argument expressed clearly and backed up with credible sources?
• Would I be convinced by this argument coming from someone else?

Critical thinking refers to the ability to evaluate information and to be aware of biases or assumptions, including your own.

Like information literacy , it involves evaluating arguments, identifying and solving problems in an objective and systematic way, and clearly communicating your ideas.

Critical thinking skills include the ability to:

You can assess information and arguments critically by asking certain questions about the source. You can use the CRAAP test , focusing on the currency , relevance , authority , accuracy , and purpose of a source of information.

Ask questions such as:

• Who is the author? Are they an expert?
• How do they make their argument? Is it backed up by evidence?

A credible source should pass the CRAAP test  and follow these guidelines:

• The information should be up to date and current.
• The author and publication should be a trusted authority on the subject you are researching.
• The sources the author cited should be easy to find, clear, and unbiased.
• For a web source, the URL and layout should signify that it is trustworthy.

Information literacy refers to a broad range of skills, including the ability to find, evaluate, and use sources of information effectively.

Being information literate means that you:

• Know how to find credible sources
• Use relevant sources to inform your research
• Understand what constitutes plagiarism
• Know how to cite your sources correctly

Confirmation bias is the tendency to search, interpret, and recall information in a way that aligns with our pre-existing values, opinions, or beliefs. It refers to the ability to recollect information best when it amplifies what we already believe. Relatedly, we tend to forget information that contradicts our opinions.

Although selective recall is a component of confirmation bias, it should not be confused with recall bias.

On the other hand, recall bias refers to the differences in the ability between study participants to recall past events when self-reporting is used. This difference in accuracy or completeness of recollection is not related to beliefs or opinions. Rather, recall bias relates to other factors, such as the length of the recall period, age, and the characteristics of the disease under investigation.

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.

9 Critical Thinking Exercises That Actually Improve Your Mind

Anthony Metivier | August 25, 2023 | Thinking

After all, the Internet is loaded with generic exercises like “read books written by leaders.”

Sorry, but that’s not a specific exercise. That’s a generic activity.

On this page, we’ll dive into specific exercise for critical thinking targeted at specific outcomes. Each exercise is designed to help you boost precise aspects of thinking so you can feel improvement as you go.

First, however, it’s good to understand what makes an exercise worthwhile. And understand why critical thinking has gotten more and more important as time moves on.

Since that is kind of counterintuitive in the age of AI, let’s dive in with a critical thinking exercise of our own.

Why Critical Thinking Skills Are More Important Now Than Ever

As the author of this blog on memory and thinking for over a decade, people ask me often if any of these skills matter anymore.

I’ve gotten the question even more frequently since AI tools like chat-GPT and Midjourney have appeared.

“Do we really need memory techniques anymore, now that I can search the Internet for anything at any time?”

“Why should I improve my thinking skills when I can read a simple summary of any book just by asking an AI?”

First, it’s still the case that a vast percentage of information has never appeared online. It’s imperative that people understand this and do hands-on, practical research with a variety of sources offline.

That said, there are certain use cases where using an AI seems to make sense. I recently published a case study demonstrating the positive use of chat-GPT for language learning , for example. But there are a few reasons we don’t want to relegate our thinking and learning to machines.

The big one is that we don’t own the platform and we certainly don’t own the data. Nor do we have general access to the people who do.

That’s troublesome because I’ve noticed bias that makes the text generators much different than the kinds of bias produced by a standard search engine. For example, instead of just getting the results, you might get a mini-discussion that essentially assumes it knows the intent behind your question.

This happened to me while working on my “Memory Detective” series. I thought it would be fun to get some feedback and ideas from chat-GPT, but it was anything but amusing.

In fact, the software effectively accused me of being biased about the bad guy I was exploring – which of course I was, just not in the way the software assumed. It’s a bad guy I was developing, after all. And moreover, I was working on fiction and made this evident in my request, even though the AI seems to have ignored this crucial point.

Here’s the kicker and the reason I’m dwelling on this point: Discovering that chat-GPT is itself biased let me to the point of feeling, however briefly, offended by the people who designed such preachy features into the program.

It’s only because I’ve done some of the critical thinking exercises below that I’m aware of my own memory biases , and was able to continue using the software objectively. We are all going to need to be increasingly objective as “the powers that be” inject their agendas into the tools we use.

In sum, even if each and everyone one of us ultimately winds up owning and designing our own personal Artificial Intelligences, we’re still going to need to think critically about both inputs, outputs and our interpretations of them. And in order to keep our critical thinking skills mobile, we’re going to need ongoing mental training .

9 Critical Thinking Exercises That Create Laser Sharp Intelligence

Authentic critical thinking exercises must always involve:

• New learning by working with information you have not encountered before
• Variety so that you experience growth in multiple areas and don’t “burn out” on just one area
• Varying levels of complexity so you experience different challenges
• Consistent practice over time

Follow those guidelines and you will succeed.

Critical Thinking Exercises For Students

Students have many needs. Above all, they need to be able to understand how people make arguments and substantiate their claims with evidence. 

One: The News Exercise

One great source for practice is the news. 

For this exercise, head over to any news website. Look for an article that includes graphs, numbers, or any representation involving numerical data.

Here’s the kind of news representation I’m talking about:

As you examine the news, ask the following questions:

• How is the news trying to help you understand the data? 
• Does the representation of the data make sense? 
• How can you determine whether or not the graph is reliable?
• How can you determine whether or not the presenter is reliable and free from bias?
• Who gets any kind of special benefit if the interpretation of the data falls in their favor?

Asking questions like these provides a powerful exercise that will sharpen your mind whenever you are presented with scientific data. 

Two: The Abilities Exercise

Do you know anyone living with a disability?

I do and you can learn more about my mentor Jon Morrow in his article 7 Life Lessons from a Guy Who Can’t Move Anything but His Face .

After reading his post, imagine what it would be like if you could only move one part of your body. Write an essay that describes how exactly your life would change from the way it is.

Another version of this exercise is to think of ways you can use your mind to box with one hand tied behind your back.

For example, you can practice debating with a timer on and give yourself increasingly smaller amounts of time to make your case. There are many lists of debate topics online to choose from, and you can sharpen your skills anytime by going through the Rhetorica ad Herennium .

Three: The Research Response Exercise

Take the following argument:

Pesticides harm the environment more than they’re worth. 

As you think through this statement, answer the following questions:

• What kind of research do you need to conduct in order to answer both for or against this statement?
• How would you outline your responses? Use a structure like this: “if A then B, and if B then C, and if C then D, and in conclusion, if A then D.”

Critical Thinking Exercises For Business

People in business need to successfully navigate sales meetings and negotiate multiple levels of management in their careers. Here are some critical thinking exercises that will help you develop skills in these areas.

Four: The Prison Exercise

Pretend that you’ve been hired to sell a neighborhood council on building a new maximum security prison. This particular neighborhood is upper-class and filled with mansions. 

What benefits can you bring together to explain why it would be a great thing for this neighborhood to house prisoners in this area?

What incentives can you include in the full package? As you consider both the benefits and the incentives, reign yourself in.

You want to think logically in order to make this a critical thinking exercise. If you indulge in flights of fancy, then it will be creative thinking exercise instead. 

Anytime you get off track, these critical thinking examples will help you get back on this path.

Five: The Facial Expression Exercise

One way to improve business success is to develop your empathy. 

For this exercise, gather a number of photographs from the newspaper or some magazines. 

As you look through the photographs, practice identifying the emotions. If you feel like you’re lacking in vocabulary for the task, consider reading The Dictionary of Emotions . You can also use an online dictionary or thesaurus to come up with words. 

Next, do some role playing. Pick one person from the photographs and imagine meeting them in real life. 

List all the questions you would ask them in order to connect with them better based on the emotion you listed when you first saw the photograph. 

Six: The Competitor Exercise

Think about your competitors in business. 

As you go through each, list their purpose for being in business. What is it that they are trying to accomplish?

Be non judgemental, realistic and focus on the most significant aspects of their purpose. 

Then, think about how you can contribute to the growth of their success without damaging your own. 

Obviously, this is a very tricky critical thinking exercise, but I’m confident you’ll find it beneficial. If you’re into sports or any other realm where competition plays a role, this exercise is also helpful. 

And if you really want to learn about critical thinking so you’re a master, check out these critical thinking books .

Critical Thinking Exercises For Adults

As mentioned, exercises that stimulate our thinking abilities are best if they are targeted at a particular outcome. 

However, there is some room for general exercises that are good for everyone. Let’s have a look at some of my favorites.

Seven: The Stakes Exercise

Many times when you’re listening to an argument, it’s easy to get hung up on the details.

A great exercise is to simply ask: What’s at stake? 

This means, what’s the real core issue? And who benefits the most if they get to be right on the issue? 

As you complete this exercise, but sure to go through both the objective and subjective reasoning of both sides. 

Also, you’ll benefit if you continually focus on how many possible answers might exist. It’s not always the case that there’s one and only one correct answer, even if situations require us to pick just one.

You’ll want to also spend time interpreting the information on both sides of the argument, and possibly doing follow-up research. In fact, if you don’t, it’s unlikely that you’ll improve your reasoning skills as much as you’d like.

Eight: Make An “Argument Map”

I’ve talked a lot about mind mapping on this blog. But there’s another powerful process called argument mapping .

This technique goes back to Plato. If you’ve read the Meno , you might remember how Socrates draws a set of figures in the dirt to display the concepts that come up during the discussion.

These days, we can use pen and paper or software to create an argument map. Here’s one from Evan Rodriguez .

To create one yourself, pick an argument where multiple reasons are involved and break things down. 

In this example, Rodriquez has separated the “because” reasons and then used the graph to help him sort through the truth by visualizing a set of if/then parameters.

Creating such argument maps provide tremendous exercise. They’re also relatively quick to produce.

You might also enjoy learning more about the history of what is sometimes called “graphicacy.” Look up people and processes like:

• Ars combinatoria
• Giordano Bruno
• Petrus Ramus
• John Venn (who introduced Venn diagrams)
• Peirce’s Existential Graphs

Nine: Memorize the Fallacies

One of the best critical thinking exercises is to learn the fallacies so well you know them when you see them or hear them in a conversation . 

There are at least two kinds of fallacies: Formal and informal. This list of fallacies is very thorough.

To commit as many of these as possible to memory, you’ll want to learn a technique called the Memory Palace . I’m happy to help you learn it here:

Let’s say you want to memorize argumentum ad lapidem or the “ appeal to the stone ” fallacy. 

You can memorize the Latin and English along with the meaning by thinking about a chair in your home and imagining yourself having an argument with a stone. In this image, you’re calling the stone’s arguments absurd without providing any evidence for why you believe this to be the case.

It’s a powerful technique and will help you spot fallacies in everyday life. Commit as many to memory as you can. 

The Ultimate Critical Thinking Exercise to Reach Peak Critical Thinking

For thousands of years, people have asked “Who am I?” 

You might not think about this as an exercise that relates to critical thinking strategies at large, but if you really submit to the question as a practice, it helps your thinking across the board.

When you take away your name, your title, the roles you play in your profession and all the games of life, who are you really? Is there a “true self” in the mix that you can always trust to be the same? 

To practice this exercise with more structure, get 15-20 index cards and write down personal qualities on each. They can be qualities like:

• Versatility

Sit down, take a deep breath and mix the cards.

Then, pick one of the cards and reflect on how that quality is perceived by others in your life:

Family, friends, co-workers. You might want to learn about how to think about yourself through the perspective of authors through my autobiographical memory post first. Or just dive in. 

Next, imagine what it would be like if that quality was completely gone from your life. Who would you be without it? Can you glimpse your true self without this label? 

Then pick up another card and repeat the process, linking each with a deep breath. Then follow-up by journaling on your experiences. Making sure to write after completing each of the exercises on this page is key to benefiting from the reflective thinking skills you’ll also want to grow.

Thank you for reading this article, and if you enjoyed these exercises, please consider going through these powerful brain exercises next.

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.

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.

3 Activities to Enhance Your Analysis in Critical Thinking

Here is a second set of exercises to help enhance critical thinking..

Posted April 16, 2021 | Reviewed by Davia Sills

At the beginning of the calendar year, I posted a piece on this blog asking if any readers wanted to develop their critical thinking as a kind of New Year’s Resolution. Over the past few months, I’ve received some positive feedback about the post and decided that continuing with the proposed series of exercises seems warranted!

So, if you’re interested in enhancing your critical thinking skills, please start with the first set of exercises in that previous post . If you have already completed those, please find the second set below. Remember, when we are given opportunities to think about our thinking , we are engaging our metacognitive processes, and that’s a foundational part of critical thinking !

We are almost always sure to come across a topic that requires critical thinking within newspapers, magazines, social media posts, and web articles. For these exercises, find such an article and analyze the structure of the argument presented within the article. Please note, almost any long text reflects an argument in the sense that it is trying to convey a point in light of either reasons or objections. An easy way of identifying whether or not an argument is present is by seeing if the piece includes words like: because, but, however, yet, therefore, or thus.

Identify the role that each statement, or proposition, plays in the piece—for example, the central claim, core reasons and core objections (for the central claim), as well as supporting reasons (i.e., reasons for reasons or reasons for objections), rebuttals (i.e., objections to objections).

Re-construct the argument using only propositions that are appropriately signaled within the article through relational cues—words like because, but, however, yet, therefore, and/or thus.

Following this re-construction, ask yourself:

1. What kind of argument structure do these propositions create?

2. What is the central claim in the argument?

3. What are the primary supports and objections?

Finish your analysis by asking yourself:

1. Was the author of the original article, for the most part, being subjective or objective?

2. If any objective propositions were presented, what evidence is provided to support them?

3. If there was subjectivity, how was the author biased?

4. Can you offer any credible reasons to dispute the author’s judgments or claims?

5. Can you offer any credible reasons to further support the author’s judgments or claims?

These activities are a great way to start working on the critical thinking skill of analysis, as they help you to identify the structure of an argument and, subsequently, construct or deconstruct arguments for the purpose of developing your own lines of reasoning. They also usher in the concept of evaluating arguments, particularly with respect to bias , which we discussed in the first post . In the following post, we will delve further into the skill of evaluation.

How to Solve the Biggest Problems With Critical Thinking Exercises

• February 10, 2018

Have you ever wanted to evaluate situations like Sherlock Holmes, or present arguments like an undefeated lawyer? Sick of being the confused and out-of-place individual in any intellectual scrum?

Critical thinking is the art, skill, and practice of getting to the crux of any subject. It allows you to see the big picture and challenge what comes between you and the truth.

This doesn’t come easy; it requires a certain amount of practice before you can become the master of all that matters . It will require the use of critical thinking exercises and practice thereof.

Critical Thinking Exercise Types

Critical thinking starts with the three powerful skills of linking ideas, structuring arguments, and recognizing incongruences. Each area needs to be practiced and applied in order for you to become the best critical thinker you can be.

Below are the three major skills of critical thinking:

• Linking ideas
• Structuring argument s
• Recognizing incongruences

1. Linking ideas

This has to do with finding connections between the seemly unrelatable or irrelevant.

Exercise: Newspaper link up

Take today’s newspaper. Brush through all articles in each section (news, sports, business, etc.). Make a list of the articles as a basic concept.

Now find ways in which each article is linked to each other, in each section of the newspaper. Find the overall theme of each section and if you can, try to link the sections of the newspaper to each other.

Once you have done all of this, try to surmise the agenda or aim of this publication.

2. Structuring arguments

Structuring arguments are elements that are involved in creating a practical, relevant, and sound argument. Before doing this exercise you will have to know what a premise and conclusion of an argument are:

Premise:  A previous statement or proposition from which another is inferred or follows as a conclusion. It is the base of an argument, theory, or undertaking.

Conclusion: The end of an argument, theory, or undertaking. A judgment or decision is reached by reasoning.

Exercise: Recognising the premise and conclusion

Look on YouTube or just on Google for some of the best theories, arguments, or speeches ever given or done.  Take the piece that you have chosen and determine what the premise of the topic is, and what the conclusion is. There can be several premises but they have to support the conclusion.

3. Recognizing incongruences

Recognizing incongruences is the ability to find holes in a theory or argument in order to find the real truth.

Exercise: Challenging the premise

Take the same information from the Recognising premise and conclusion exercise you have done above, and see if you can figure out if any of the premises do not support or link to the conclusion.

If all premises link with the conclusions, then look into the premises themselves. See if there are any false assumptions ( or fallacies ) in the premises and research their validity.

Analyze the premises to see that there has not been a statement that is assumed true but is actually false.

Critical Thinking Exercises for Adults

Too often as adults, we are steadfast and strong in our already formed, accepted, and practiced beliefs.

We often do not challenge what is just accepted as truth or “the way it is.” We could learn a thing or two from the younger side of humanity, especially the way that they question everything, even that which is considered logical.

Exercise: Tell a space alien

You can apply this to any information or theory, but in the interest of practice, you can look for the 10 most interesting theories on the internet.

You will play both the inquisitive space alien and yourself trying to answer and explain the topic.

Start by explaining the topic as if it were to a space alien who has no prior knowledge of Earth and it’s ways, but somehow the alien can speak English. Then become the alien (dress up if you wish) and ask questions about the topic from a completely uninformed perspective.

For example, you would explain a game of tennis, as two people who use a tool called a racquet to hit a ball over a net and into a certain square. The one who does not return the ball loses that round and the other gets a point, until the one has enough points to win.

You as the alien when then ask things such as: Why are there only two people playing? Why does the crowd get so excited? Why does the crowd not jump on the court and get involved? Why do they use racquets and not something else? Etcetera…

Critical Thinking Exercises for College Students

Due to the amount of information absorbed in a term or semester of college, college students don’t get much of a chance to look back on what they have learned. The river of information keeps flowing and the students keep swimming on.

It often happens that a year or two down the line, you will be looking up something that you did in the first year of college. It is thus very important to take at least one day once you are done with the term, to revise and clarify what you have achieved? What could you have done better? And how you could improve on the strategies you applied?

Exercise: Revising the term or semester

At the end of a term or semester of college, take each area of knowledge you have gone through in that time. You can divide this by subject, yet if you feel that certain subjects can be merged into one area of knowledge then do so.

Answer these questions about the college term and the knowledge you gain in that time:

• In your own perception (not the reports’) what was your performance like this term?
• How effective were your strategies in getting through the work? (Time management, studying strategies etc.)
• What would you like to get out of the next term that you didn’t get in this term?
• How could you improve on these strategies?
• What are the major practical skills you acquired from this term and how could they be put to use in future?

Don’t limit the answers to the study work only, but expand into what you learned from the environment or something you inadvertently learned.

For example you learned, useful social and networking skills by being a part of many events and social groups, or you learned how to respond to people of authority effectively when dealing with a difficult lecturer.

Critical Thinking Exercises for Children

Critical thinking Exercises work well for kids as they develop the application of critical thinking. Children are mostly really good at critical thinking questioning; asking why? Why? Why….

Where children usually fall short is self-evaluation and seeing other perspectives.

It is also important to note that there will be different exercises for different age groups. Smaller children do not have the capacity to think in a certain way, just by the way the human brain naturally develops.

Exercise for younger children: Interactive questioning

When children are very young, they won’t have the patience or concentration to stay engaged in a certain activity for too long. The best thing to do for these children is actively use critical thinking exercises in their daily lives.

Ask questions that will actively engage the children in critical thinking such as:

• Open-ended questions – Instead of the regular yes and no answers, inspire your children to elaborate on their answers to create understanding and validation to what they say.
• Encourage Explanations – Ask your child to explain a topic or something they saw with a bit more detail than they would usually give. Make sure they feel as if the question does not have a right or wrong answer, so they have the freedom to express themselves.
• Multiple Answers – This works especially well in situations that are challenging to them. Ask your child what they should do in a certain situation and ask them to come up with at least three different answers or responses.
• Evaluate Decisions – Once something has happened to the child, ask the child what they thought about the situation and how they would handle it differently.

On top of all of this, inspire your kids to question everything. It is absolutely crucial. Here is an inspiring video to help you with this action:

Exercise for older children: Image description Exercises

Older children are a little less inquisitive than the younger children and often get caught up on the right or wrong answer. This makes them less inclined to come up with multiple solutions and usually only give one answer at a time until they get validation that they are correct.

With the image description exercise you take any image (make sure it’s age appropriate) and make them describe what they see and elaborate about the subjects in the picture and the situation of the picture. Push them to give multiple answers and scenarios.

Exercise Your Critical Thought

Critical thinking is an art and a skill and can thus be honed and improved by constant practice and application. The best way to do this is through critical thinking exercises .

Take ten to twenty minutes a day to sharpen your critical thinking and you will soon notice that the rest of your life will be full of inspiration and better understanding.

Try These Strategies for Building Critical-Thinking Skills

We hear all too often that critical-thinking skills are essential for students. But what, specifically, are critical-thinking skills, and how can instructors better help students build them? We’re breaking down what exactly critical-thinking skills are, and offering a few critical-thinking activities to add to your course.

What is critical thinking?

According to the Paul-Elder Framework , critical thinking is “that mode of thinking—about any subject, content, or problem—in which the thinker improves the quality of [their] thinking by skillfully taking charge of the structures inherent in thinking and imposing intellectual standards upon them.” Translation: It’s about analyzing the facts from as objective as a viewpoint as possible, while minimizing personal biases.

With 69.6% of employers claiming these skills are indicative of employee success, educators need to make sure their lessons help students build critical-thinking skills.

Assessing your students’ critical-thinking skills

Assessing your students’ critical-thinking skills is just as important as fostering them. According to the Paul-Elder Critical Thinking Framework , a “well-cultivated critical thinker” can:

• Raise vital questions and problems, formulating them clearly and precisely
• Gather and assess relevant information, using abstract ideas to interpret it effectively
• Come to well-reasoned conclusions and solutions, testing them against relevant criteria and standards
• Think open-mindedly within alternative systems of thought, recognizing and assessing, as need be, their assumptions, implications, and practical consequences
• Communicate effectively with others in figuring out solutions to complex problems

Think about if your syllabus checks these boxes. If not, try incorporating some of these strategies in your course.

Strategy 1: Use reflective thinking questions

Reflective thinking involves “consideration of the larger context, the meaning, and the implications of an experience or action.” In other words, reflection doesn’t just mean jotting down what you did or plan to do. It means considering why what you did or plan to do matters. It means writing to help you better understand something. It means exploring emotions, feelings, reactions and knowledges. And, it can even mean catharsis. Think of reflection as exploring the “so what” instead of just the “what.”

Check out this resource from the Colorado Department of Education for reflective thinking questions you can include in your course.

Strategy 2: Structure class discussions thoughtfully

Building critical-thinking skills is less about finding the right answer and more about the quest to get there. That quest is the thoughtful consideration and discussion that occurs amongst the students in your course. Try not to start with just one right answer in your head when you pose a question to your class, and instead think about the questions, comments and lines of thinking that your question — and potential answers for it — will spur.

For questions you can use to get your students thinking critically, check out these Universal Intellectual Standards .

Strategy 3: Use exercises to demonstrate biases

Here’s a $5 word to pull out at pub trivia night: Pareidolia . It’s the tendency to “perceive a specific, often meaningful image in a random or ambiguous visual pattern.” In practice, it could mean something as innocuous as seeing a human face in the whorls of a tree trunk or in a grilled cheese. Or, it might mean seeing a pattern that fits within your own biases without consideration for alternative meanings.

This exercise has your students analyze videos of animals communicating to analyze how their existing biases affect their views on a topic. Or, websites like School of Thought , a nonprofit organization dedicated to “promoting critical thinking, reason and understanding,” offer recourses surrounding logical fallacies and cognitive biases. Using hands-on activities helps students bridge the gap between learning about critical thinking in the abstract and applying it through tactile experiences.

A Short Guide to Building Your Team’s Critical Thinking Skills

• Matt Plummer

Critical thinking isn’t an innate skill. It can be learned.

Most employers lack an effective way to objectively assess critical thinking skills and most managers don’t know how to provide specific instruction to team members in need of becoming better thinkers. Instead, most managers employ a sink-or-swim approach, ultimately creating work-arounds to keep those who can’t figure out how to “swim” from making important decisions. But it doesn’t have to be this way. To demystify what critical thinking is and how it is developed, the author’s team turned to three research-backed models: The Halpern Critical Thinking Assessment, Pearson’s RED Critical Thinking Model, and Bloom’s Taxonomy. Using these models, they developed the Critical Thinking Roadmap, a framework that breaks critical thinking down into four measurable phases: the ability to execute, synthesize, recommend, and generate.

With critical thinking ranking among the most in-demand skills for job candidates , you would think that educational institutions would prepare candidates well to be exceptional thinkers, and employers would be adept at developing such skills in existing employees. Unfortunately, both are largely untrue.

Critical Thinking

Critical thinking is a widely accepted educational goal. Its definition is contested, but the competing definitions can be understood as differing conceptions of the same basic concept: careful thinking directed to a goal. Conceptions differ with respect to the scope of such thinking, the type of goal, the criteria and norms for thinking carefully, and the thinking components on which they focus. Its adoption as an educational goal has been recommended on the basis of respect for students’ autonomy and preparing students for success in life and for democratic citizenship. “Critical thinkers” have the dispositions and abilities that lead them to think critically when appropriate. The abilities can be identified directly; the dispositions indirectly, by considering what factors contribute to or impede exercise of the abilities. Standardized tests have been developed to assess the degree to which a person possesses such dispositions and abilities. Educational intervention has been shown experimentally to improve them, particularly when it includes dialogue, anchored instruction, and mentoring. Controversies have arisen over the generalizability of critical thinking across domains, over alleged bias in critical thinking theories and instruction, and over the relationship of critical thinking to other types of thinking.

Use of the term ‘critical thinking’ to describe an educational goal goes back to the American philosopher John Dewey (1910), who more commonly called it ‘reflective thinking’. He defined it as

active, persistent and careful consideration of any belief or supposed form of knowledge in the light of the grounds that support it, and the further conclusions to which it tends. (Dewey 1910: 6; 1933: 9)

and identified a habit of such consideration with a scientific attitude of mind. His lengthy quotations of Francis Bacon, John Locke, and John Stuart Mill indicate that he was not the first person to propose development of a scientific attitude of mind as an educational goal.

In the 1930s, many of the schools that participated in the Eight-Year Study of the Progressive Education Association (Aikin 1942) adopted critical thinking as an educational goal, for whose achievement the study’s Evaluation Staff developed tests (Smith, Tyler, & Evaluation Staff 1942). Glaser (1941) showed experimentally that it was possible to improve the critical thinking of high school students. Bloom’s influential taxonomy of cognitive educational objectives (Bloom et al. 1956) incorporated critical thinking abilities. Ennis (1962) proposed 12 aspects of critical thinking as a basis for research on the teaching and evaluation of critical thinking ability.

Since 1980, an annual international conference in California on critical thinking and educational reform has attracted tens of thousands of educators from all levels of education and from many parts of the world. Also since 1980, the state university system in California has required all undergraduate students to take a critical thinking course. Since 1983, the Association for Informal Logic and Critical Thinking has sponsored sessions in conjunction with the divisional meetings of the American Philosophical Association (APA). In 1987, the APA’s Committee on Pre-College Philosophy commissioned a consensus statement on critical thinking for purposes of educational assessment and instruction (Facione 1990a). Researchers have developed standardized tests of critical thinking abilities and dispositions; for details, see the Supplement on Assessment . Educational jurisdictions around the world now include critical thinking in guidelines for curriculum and assessment. Political and business leaders endorse its importance.

For details on this history, see the Supplement on History .

2. Examples and Non-Examples

Before considering the definition of critical thinking, it will be helpful to have in mind some examples of critical thinking, as well as some examples of kinds of thinking that would apparently not count as critical thinking.

Dewey (1910: 68–71; 1933: 91–94) takes as paradigms of reflective thinking three class papers of students in which they describe their thinking. The examples range from the everyday to the scientific.

Transit : “The other day, when I was down town on 16th Street, a clock caught my eye. I saw that the hands pointed to 12:20. This suggested that I had an engagement at 124th Street, at one o'clock. I reasoned that as it had taken me an hour to come down on a surface car, I should probably be twenty minutes late if I returned the same way. I might save twenty minutes by a subway express. But was there a station near? If not, I might lose more than twenty minutes in looking for one. Then I thought of the elevated, and I saw there was such a line within two blocks. But where was the station? If it were several blocks above or below the street I was on, I should lose time instead of gaining it. My mind went back to the subway express as quicker than the elevated; furthermore, I remembered that it went nearer than the elevated to the part of 124th Street I wished to reach, so that time would be saved at the end of the journey. I concluded in favor of the subway, and reached my destination by one o’clock.” (Dewey 1910: 68-69; 1933: 91-92)

Ferryboat : “Projecting nearly horizontally from the upper deck of the ferryboat on which I daily cross the river is a long white pole, having a gilded ball at its tip. It suggested a flagpole when I first saw it; its color, shape, and gilded ball agreed with this idea, and these reasons seemed to justify me in this belief. But soon difficulties presented themselves. The pole was nearly horizontal, an unusual position for a flagpole; in the next place, there was no pulley, ring, or cord by which to attach a flag; finally, there were elsewhere on the boat two vertical staffs from which flags were occasionally flown. It seemed probable that the pole was not there for flag-flying.

“I then tried to imagine all possible purposes of the pole, and to consider for which of these it was best suited: (a) Possibly it was an ornament. But as all the ferryboats and even the tugboats carried poles, this hypothesis was rejected. (b) Possibly it was the terminal of a wireless telegraph. But the same considerations made this improbable. Besides, the more natural place for such a terminal would be the highest part of the boat, on top of the pilot house. (c) Its purpose might be to point out the direction in which the boat is moving.

“In support of this conclusion, I discovered that the pole was lower than the pilot house, so that the steersman could easily see it. Moreover, the tip was enough higher than the base, so that, from the pilot's position, it must appear to project far out in front of the boat. Morevoer, the pilot being near the front of the boat, he would need some such guide as to its direction. Tugboats would also need poles for such a purpose. This hypothesis was so much more probable than the others that I accepted it. I formed the conclusion that the pole was set up for the purpose of showing the pilot the direction in which the boat pointed, to enable him to steer correctly.” (Dewey 1910: 69-70; 1933: 92-93)

Bubbles : “In washing tumblers in hot soapsuds and placing them mouth downward on a plate, bubbles appeared on the outside of the mouth of the tumblers and then went inside. Why? The presence of bubbles suggests air, which I note must come from inside the tumbler. I see that the soapy water on the plate prevents escape of the air save as it may be caught in bubbles. But why should air leave the tumbler? There was no substance entering to force it out. It must have expanded. It expands by increase of heat, or by decrease of pressure, or both. Could the air have become heated after the tumbler was taken from the hot suds? Clearly not the air that was already entangled in the water. If heated air was the cause, cold air must have entered in transferring the tumblers from the suds to the plate. I test to see if this supposition is true by taking several more tumblers out. Some I shake so as to make sure of entrapping cold air in them. Some I take out holding mouth downward in order to prevent cold air from entering. Bubbles appear on the outside of every one of the former and on none of the latter. I must be right in my inference. Air from the outside must have been expanded by the heat of the tumbler, which explains the appearance of the bubbles on the outside. But why do they then go inside? Cold contracts. The tumbler cooled and also the air inside it. Tension was removed, and hence bubbles appeared inside. To be sure of this, I test by placing a cup of ice on the tumbler while the bubbles are still forming outside. They soon reverse” (Dewey 1910: 70–71; 1933: 93–94).

Dewey (1910, 1933) sprinkles his book with other examples of critical thinking. We will refer to the following.

Weather : A man on a walk notices that it has suddenly become cool, thinks that it is probably going to rain, looks up and sees a dark cloud obscuring the sun, and quickens his steps (1910: 6–10; 1933: 9–13).

Disorder : A man finds his rooms on his return to them in disorder with his belongings thrown about, thinks at first of burglary as an explanation, then thinks of mischievous children as being an alternative explanation, then looks to see whether valuables are missing, and discovers that they are (1910: 82–83; 1933: 166–168).

Typhoid : A physician diagnosing a patient whose conspicuous symptoms suggest typhoid avoids drawing a conclusion until more data are gathered by questioning the patient and by making tests (1910: 85–86; 1933: 170).

Blur : A moving blur catches our eye in the distance, we ask ourselves whether it is a cloud of whirling dust or a tree moving its branches or a man signaling to us, we think of other traits that should be found on each of those possibilities, and we look and see if those traits are found (1910: 102, 108; 1933: 121, 133).

Suction pump : In thinking about the suction pump, the scientist first notes that it will draw water only to a maximum height of 33 feet at sea level and to a lesser maximum height at higher elevations, selects for attention the differing atmospheric pressure at these elevations, sets up experiments in which the air is removed from a vessel containing water (when suction no longer works) and in which the weight of air at various levels is calculated, compares the results of reasoning about the height to which a given weight of air will allow a suction pump to raise water with the observed maximum height at different elevations, and finally assimilates the suction pump to such apparently different phenomena as the siphon and the rising of a balloon (1910: 150–153; 1933: 195–198).

Diamond : A passenger in a car driving in a diamond lane reserved for vehicles with at least one passenger notices that the diamond marks on the pavement are far apart in some places and close together in others. Why? The driver suggests that the reason may be that the diamond marks are not needed where there is a solid double line separating the diamond line from the adjoining lane, but are needed when there is a dotted single line permitting crossing into the diamond lane. Further observation confirms that the diamonds are close together when a dotted line separates the diamond lane from its neighbour, but otherwise far apart.

Rash : A woman suddenly develops a very itchy red rash on her throat and upper chest. She recently noticed a mark on the back of her right hand, but was not sure whether the mark was a rash or a scrape. She lies down in bed and thinks about what might be causing the rash and what to do about it. About two weeks before, she began taking blood pressure medication that contained a sulfa drug, and the pharmacist had warned her, in view of a previous allergic reaction to a medication containing a sulfa drug, to be on the alert for an allergic reaction; however, she had been taking the medication for two weeks with no such effect. The day before, she began using a new cream on her neck and upper chest; against the new cream as the cause was mark on the back of her hand, which had not been exposed to the cream. She began taking probiotics about a month before. She also recently started new eye drops, but she supposed that manufacturers of eye drops would be careful not to include allergy-causing components in the medication. The rash might be a heat rash, since she recently was sweating profusely from her upper body. Since she is about to go away on a short vacation, where she would not have access to her usual physician, she decides to keep taking the probiotics and using the new eye drops but to discontinue the blood pressure medication and to switch back to the old cream for her neck and upper chest. She forms a plan to consult her regular physician on her return about the blood pressure medication.

Candidate : Although Dewey included no examples of thinking directed at appraising the arguments of others, such thinking has come to be considered a kind of critical thinking. We find an example of such thinking in the performance task on the Collegiate Learning Assessment (CLA+), which its sponsoring organization describes as

a performance-based assessment that provides a measure of an institution’s contribution to the development of critical-thinking and written communication skills of its students. (Council for Aid to Education 2017)

A sample task posted on its website requires the test-taker to write a report for public distribution evaluating a fictional candidate’s policy proposals and their supporting arguments, using supplied background documents, with a recommendation on whether to endorse the candidate.

Immediate acceptance of an idea that suggests itself as a solution to a problem (e.g., a possible explanation of an event or phenomenon, an action that seems likely to produce a desired result) is “uncritical thinking, the minimum of reflection” (Dewey 1910: 13). On-going suspension of judgment in the light of doubt about a possible solution is not critical thinking (Dewey 1910: 108). Critique driven by a dogmatically held political or religious ideology is not critical thinking; thus Paulo Freire (1968 [1970]) is using the term (e.g., at 1970: 71, 81, 100, 146) in a more politically freighted sense that includes not only reflection but also revolutionary action against oppression. Derivation of a conclusion from given data using an algorithm is not critical thinking.

What is critical thinking? There are many definitions. Ennis (2016) lists 14 philosophically oriented scholarly definitions and three dictionary definitions. Following Rawls (1971), who distinguished his conception of justice from a utilitarian conception but regarded them as rival conceptions of the same concept, Ennis maintains that the 17 definitions are different conceptions of the same concept. Rawls articulated the shared concept of justice as

a characteristic set of principles for assigning basic rights and duties and for determining… the proper distribution of the benefits and burdens of social cooperation. (Rawls 1971: 5)

Bailin et al. (1999b) claim that, if one considers what sorts of thinking an educator would take not to be critical thinking and what sorts to be critical thinking, one can conclude that educators typically understand critical thinking to have at least three features.

• It is done for the purpose of making up one’s mind about what to believe or do.
• The person engaging in the thinking is trying to fulfill standards of adequacy and accuracy appropriate to the thinking.
• The thinking fulfills the relevant standards to some threshold level.

One could sum up the core concept that involves these three features by saying that critical thinking is careful goal-directed thinking. This core concept seems to apply to all the examples of critical thinking described in the previous section. As for the non-examples, their exclusion depends on construing careful thinking as excluding jumping immediately to conclusions, suspending judgment no matter how strong the evidence, reasoning from an unquestioned ideological or religious perspective, and routinely using an algorithm to answer a question.

If the core of critical thinking is careful goal-directed thinking, conceptions of it can vary according to its presumed scope, its presumed goal, one’s criteria and threshold for being careful, and the thinking component on which one focuses As to its scope, some conceptions (e.g., Dewey 1910, 1933) restrict it to constructive thinking on the basis of one’s own observations and experiments, others (e.g., Ennis 1962; Fisher & Scriven 1997; Johnson 1992) to appraisal of the products of such thinking. Ennis (1991) and Bailin et al. (1999b) take it to cover both construction and appraisal. As to its goal, some conceptions restrict it to forming a judgment (Dewey 1910, 1933; Lipman 1987; Facione 1990a). Others allow for actions as well as beliefs as the end point of a process of critical thinking (Ennis 1991; Bailin et al. 1999b). As to the criteria and threshold for being careful, definitions vary in the term used to indicate that critical thinking satisfies certain norms: “intellectually disciplined” (Scriven & Paul 1987), “reasonable” (Ennis 1991), “skillful” (Lipman 1987), “skilled” (Fisher & Scriven 1997), “careful” (Bailin & Battersby 2009). Some definitions specify these norms, referring variously to “consideration of any belief or supposed form of knowledge in the light of the grounds that support it and the further conclusions to which it tends” (Dewey 1910, 1933); “the methods of logical inquiry and reasoning” (Glaser 1941); “conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication” (Scriven & Paul 1987); the requirement that “it is sensitive to context, relies on criteria, and is self-correcting” (Lipman 1987); “evidential, conceptual, methodological, criteriological, or contextual considerations” (Facione 1990a); and “plus-minus considerations of the product in terms of appropriate standards (or criteria)” (Johnson 1992). Stanovich and Stanovich (2010) propose to ground the concept of critical thinking in the concept of rationality, which they understand as combining epistemic rationality (fitting one’s beliefs to the world) and instrumental rationality (optimizing goal fulfillment); a critical thinker, in their view, is someone with “a propensity to override suboptimal responses from the autonomous mind” (2010: 227). These variant specifications of norms for critical thinking are not necessarily incompatible with one another, and in any case presuppose the core notion of thinking carefully. As to the thinking component singled out, some definitions focus on suspension of judgment during the thinking (Dewey 1910; McPeck 1981), others on inquiry while judgment is suspended (Bailin & Battersby 2009), others on the resulting judgment (Facione 1990a), and still others on the subsequent emotive response (Siegel 1988).

In educational contexts, a definition of critical thinking is a “programmatic definition” (Scheffler 1960: 19). It expresses a practical program for achieving an educational goal. For this purpose, a one-sentence formulaic definition is much less useful than articulation of a critical thinking process, with criteria and standards for the kinds of thinking that the process may involve. The real educational goal is recognition, adoption and implementation by students of those criteria and standards. That adoption and implementation in turn consists in acquiring the knowledge, abilities and dispositions of a critical thinker.

Conceptions of critical thinking generally do not include moral integrity as part of the concept. Dewey, for example, took critical thinking to be the ultimate intellectual goal of education, but distinguished it from the development of social cooperation among school children, which he took to be the central moral goal. Ennis (1996, 2011) added to his previous list of critical thinking dispositions a group of dispositions to care about the dignity and worth of every person, which he described as a “correlative” (1996) disposition without which critical thinking would be less valuable and perhaps harmful. An educational program that aimed at developing critical thinking but not the correlative disposition to care about the dignity and worth of every person, he asserted, “would be deficient and perhaps dangerous” (Ennis 1996: 172).

Dewey thought that education for reflective thinking would be of value to both the individual and society; recognition in educational practice of the kinship to the scientific attitude of children’s native curiosity, fertile imagination and love of experimental inquiry “would make for individual happiness and the reduction of social waste” (Dewey 1910: iii). Schools participating in the Eight-Year Study took development of the habit of reflective thinking and skill in solving problems as a means to leading young people to understand, appreciate and live the democratic way of life characteristic of the United States (Aikin 1942: 17–18, 81). Harvey Siegel (1988: 55–61) has offered four considerations in support of adopting critical thinking as an educational ideal. (1) Respect for persons requires that schools and teachers honour students’ demands for reasons and explanations, deal with students honestly, and recognize the need to confront students’ independent judgment; these requirements concern the manner in which teachers treat students. (2) Education has the task of preparing children to be successful adults, a task that requires development of their self-sufficiency. (3) Education should initiate children into the rational traditions in such fields as history, science and mathematics. (4) Education should prepare children to become democratic citizens, which requires reasoned procedures and critical talents and attitudes. To supplement these considerations, Siegel (1988: 62–90) responds to two objections: the ideology objection that adoption of any educational ideal requires a prior ideological commitment and the indoctrination objection that cultivation of critical thinking cannot escape being a form of indoctrination.

Despite the diversity of our 11 examples, one can recognize a common pattern. Dewey analyzed it as consisting of five phases:

• suggestions , in which the mind leaps forward to a possible solution;
• an intellectualization of the difficulty or perplexity into a problem to be solved, a question for which the answer must be sought;
• the use of one suggestion after another as a leading idea, or hypothesis , to initiate and guide observation and other operations in collection of factual material;
• the mental elaboration of the idea or supposition as an idea or supposition ( reasoning , in the sense on which reasoning is a part, not the whole, of inference); and
• testing the hypothesis by overt or imaginative action. (Dewey 1933: 106–107; italics in original)

The process of reflective thinking consisting of these phases would be preceded by a perplexed, troubled or confused situation and followed by a cleared-up, unified, resolved situation (Dewey 1933: 106). The term ‘phases’ replaced the term ‘steps’ (Dewey 1910: 72), thus removing the earlier suggestion of an invariant sequence. Variants of the above analysis appeared in (Dewey 1916: 177) and (Dewey 1938: 101–119).

The variant formulations indicate the difficulty of giving a single logical analysis of such a varied process. The process of critical thinking may have a spiral pattern, with the problem being redefined in the light of obstacles to solving it as originally formulated. For example, the person in Transit might have concluded that getting to the appointment at the scheduled time was impossible and have reformulated the problem as that of rescheduling the appointment for a mutually convenient time. Further, defining a problem does not always follow after or lead immediately to an idea of a suggested solution. Nor should it do so, as Dewey himself recognized in describing the physician in Typhoid as avoiding any strong preference for this or that conclusion before getting further information (Dewey 1910: 85; 1933: 170). People with a hypothesis in mind, even one to which they have a very weak commitment, have a so-called “confirmation bias” (Nickerson 1998): they are likely to pay attention to evidence that confirms the hypothesis and to ignore evidence that counts against it or for some competing hypothesis. Detectives, intelligence agencies, and investigators of airplane accidents are well advised to gather relevant evidence systematically and to postpone even tentative adoption of an explanatory hypothesis until the collected evidence rules out with the appropriate degree of certainty all but one explanation. Dewey’s analysis of the critical thinking process can be faulted as well for requiring acceptance or rejection of a possible solution to a defined problem, with no allowance for deciding in the light of the available evidence to suspend judgment. Further, given the great variety of kinds of problems for which reflection is appropriate, there is likely to be variation in its component events. Perhaps the best way to conceptualize the critical thinking process is as a checklist whose component events can occur in a variety of orders, selectively, and more than once. These component events might include (1) noticing a difficulty, (2) defining the problem, (3) dividing the problem into manageable sub-problems, (4) formulating a variety of possible solutions to the problem or sub-problem, (5) determining what evidence is relevant to deciding among possible solutions to the problem or sub-problem, (6) devising a plan of systematic observation or experiment that will uncover the relevant evidence, (7) carrying out the plan of systematic observation or experimentation, (8) noting the results of the systematic observation or experiment, (9) gathering relevant testimony and information from others, (10) judging the credibility of testimony and information gathered from others, (11) drawing conclusions from gathered evidence and accepted testimony, and (12) accepting a solution that the evidence adequately supports (cf. Hitchcock 2017: 485).

Checklist conceptions of the process of critical thinking are open to the objection that they are too mechanical and procedural to fit the multi-dimensional and emotionally charged issues for which critical thinking is urgently needed (Paul 1984). For such issues, a more dialectical process is advocated, in which competing relevant world views are identified, their implications explored, and some sort of creative synthesis attempted.

If one considers the critical thinking process illustrated by the 11 examples, one can identify distinct kinds of mental acts and mental states that form part of it. To distinguish, label and briefly characterize these components is a useful preliminary to identifying abilities, skills, dispositions, attitudes, habits and the like that contribute causally to thinking critically. Identifying such abilities and habits is in turn a useful preliminary to setting educational goals. Setting the goals is in its turn a useful preliminary to designing strategies for helping learners to achieve the goals and to designing ways of measuring the extent to which learners have done so. Such measures provide both feedback to learners on their achievement and a basis for experimental research on the effectiveness of various strategies for educating people to think critically. Let us begin, then, by distinguishing the kinds of mental acts and mental events that can occur in a critical thinking process.

• Observing : One notices something in one’s immediate environment (sudden cooling of temperature in Weather , bubbles forming outside a glass and then going inside in Bubbles , a moving blur in the distance in Blur , a rash in Rash ). Or one notes the results of an experiment or systematic observation (valuables missing in Disorder , no suction without air pressure in Suction pump )
• Feeling : One feels puzzled or uncertain about something (how to get to an appointment on time in Transit , why the diamonds vary in frequency in Diamond ). One wants to resolve this perplexity. One feels satisfaction once one has worked out an answer (to take the subway express in Transit , diamonds closer when needed as a warning in Diamond ).
• Wondering : One formulates a question to be addressed (why bubbles form outside a tumbler taken from hot water in Bubbles , how suction pumps work in Suction pump , what caused the rash in Rash ).
• Imagining : One thinks of possible answers (bus or subway or elevated in Transit , flagpole or ornament or wireless communication aid or direction indicator in Ferryboat , allergic reaction or heat rash in Rash ).
• Inferring : One works out what would be the case if a possible answer were assumed (valuables missing if there has been a burglary in Disorder , earlier start to the rash if it is an allergic reaction to a sulfa drug in Rash ). Or one draws a conclusion once sufficient relevant evidence is gathered (take the subway in Transit , burglary in Disorder , discontinue blood pressure medication and new cream in Rash ).
• Knowledge : One uses stored knowledge of the subject-matter to generate possible answers or to infer what would be expected on the assumption of a particular answer (knowledge of a city’s public transit system in Transit , of the requirements for a flagpole in Ferryboat , of Boyle’s law in Bubbles , of allergic reactions in Rash ).
• Experimenting : One designs and carries out an experiment or a systematic observation to find out whether the results deduced from a possible answer will occur (looking at the location of the flagpole in relation to the pilot’s position in Ferryboat , putting an ice cube on top of a tumbler taken from hot water in Bubbles , measuring the height to which a suction pump will draw water at different elevations in Suction pump , noticing the frequency of diamonds when movement to or from a diamond lane is allowed in Diamond ).
• Consulting : One finds a source of information, gets the information from the source, and makes a judgment on whether to accept it. None of our 11 examples include searching for sources of information. In this respect they are unrepresentative, since most people nowadays have almost instant access to information relevant to answering any question, including many of those illustrated by the examples. However, Candidate includes the activities of extracting information from sources and evaluating its credibility.
• Identifying and analyzing arguments : One notices an argument and works out its structure and content as a preliminary to evaluating its strength. This activity is central to Candidate . It is an important part of a critical thinking process in which one surveys arguments for various positions on an issue.
• Judging : One makes a judgment on the basis of accumulated evidence and reasoning, such as the judgment in Ferryboat that the purpose of the pole is to provide direction to the pilot.
• Deciding : One makes a decision on what to do or on what policy to adopt, as in the decision in Transit to take the subway.

By definition, a person who does something voluntarily is both willing and able to do that thing at that time. Both the willingness and the ability contribute causally to the person’s action, in the sense that the voluntary action would not occur if either (or both) of these were lacking. For example, suppose that one is standing with one’s arms at one’s sides and one voluntarily lifts one’s right arm to an extended horizontal position. One would not do so if one were unable to lift one’s arm, if for example one’s right side was paralyzed as the result of a stroke. Nor would one do so if one were unwilling to lift one’s arm, if for example one were participating in a street demonstration at which a white supremacist was urging the crowd to lift their right arm in a Nazi salute and one were unwilling to express support in this way for the racist Nazi ideology. The same analysis applies to a voluntary mental process of thinking critically. It requires both willingness and ability to think critically, including willingness and ability to perform each of the mental acts that compose the process and to coordinate those acts in a sequence that is directed at resolving the initiating perplexity.

Consider willingness first. We can identify causal contributors to willingness to think critically by considering factors that would cause a person who was able to think critically about an issue nevertheless not to do so (Hamby 2014). For each factor, the opposite condition thus contributes causally to willingness to think critically on a particular occasion. For example, people who habitually jump to conclusions without considering alternatives will not think critically about issues that arise, even if they have the required abilities. The contrary condition of willingness to suspend judgment is thus a causal contributor to thinking critically.

Now consider ability. In contrast to the ability to move one’s arm, which can be completely absent because a stroke has left the arm paralyzed, the ability to think critically is a developed ability, whose absence is not a complete absence of ability to think but absence of ability to think well. We can identify the ability to think well directly, in terms of the norms and standards for good thinking. In general, to be able do well the thinking activities that can be components of a critical thinking process, one needs to know the concepts and principles that characterize their good performance, to recognize in particular cases that the concepts and principles apply, and to apply them. The knowledge, recognition and application may be procedural rather than declarative. It may be domain-specific rather than widely applicable, and in either case may need subject-matter knowledge, sometimes of a deep kind.

Reflections of the sort illustrated by the previous two paragraphs have led scholars to identify the knowledge, abilities and dispositions of a “critical thinker”, i.e., someone who thinks critically whenever it is appropriate to do so. We turn now to these three types of causal contributors to thinking critically. We start with dispositions, since arguably these are the most powerful contributors to being a critical thinker, can be fostered at an early stage of a child’s development, and are susceptible to general improvement (Glaser 1941: 175)

8. Critical Thinking Dispositions

Educational researchers use the term ‘dispositions’ broadly for the habits of mind and attitudes that contribute causally to being a critical thinker. Some writers (e.g., Paul & Elder 2006; Hamby 2014; Bailin & Battersby 2016) propose to use the term ‘virtues’ for this dimension of a critical thinker. The virtues in question, although they are virtues of character, concern the person’s ways of thinking rather than the person’s ways of behaving towards others. They are not moral virtues but intellectual virtues, of the sort articulated by Zagzebski (1996) and discussed by Turri, Alfano, and Greco (2017).

On a realistic conception, thinking dispositions or intellectual virtues are real properties of thinkers. They are general tendencies, propensities, or inclinations to think in particular ways in particular circumstances, and can be genuinely explanatory (Siegel 1999). Sceptics argue that there is no evidence for a specific mental basis for the habits of mind that contribute to thinking critically, and that it is pedagogically misleading to posit such a basis (Bailin et al. 1999a). Whatever their status, critical thinking dispositions need motivation for their initial formation in a child—motivation that may be external or internal. As children develop, the force of habit will gradually become important in sustaining the disposition (Nieto & Valenzuela 2012). Mere force of habit, however, is unlikely to sustain critical thinking dispositions. Critical thinkers must value and enjoy using their knowledge and abilities to think things through for themselves. They must be committed to, and lovers of, inquiry.

A person may have a critical thinking disposition with respect to only some kinds of issues. For example, one could be open-minded about scientific issues but not about religious issues. Similarly, one could be confident in one’s ability to reason about the theological implications of the existence of evil in the world but not in one’s ability to reason about the best design for a guided ballistic missile.

Critical thinking dispositions can usefully be divided into initiating dispositions (those that contribute causally to starting to think critically about an issue) and internal dispositions (those that contribute causally to doing a good job of thinking critically once one has started) (Facione 1990a: 25). The two categories are not mutually exclusive. For example, open-mindedness, in the sense of willingness to consider alternative points of view to one’s own, is both an initiating and an internal disposition.

Using the strategy of considering factors that would block people with the ability to think critically from doing so, we can identify as initiating dispositions for thinking critically attentiveness, a habit of inquiry, self-confidence, courage, open-mindedness, willingness to suspend judgment, trust in reason, wanting evidence for one’s beliefs, and seeking the truth. We consider briefly what each of these dispositions amounts to, in each case citing sources that acknowledge them.

• Attentiveness : One will not think critically if one fails to recognize an issue that needs to be thought through. For example, the pedestrian in Weather would not have looked up if he had not noticed that the air was suddenly cooler. To be a critical thinker, then, one needs to be habitually attentive to one’s surroundings, noticing not only what one senses but also sources of perplexity in messages received and in one’s own beliefs and attitudes (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Habit of inquiry : Inquiry is effortful, and one needs an internal push to engage in it. For example, the student in Bubbles could easily have stopped at idle wondering about the cause of the bubbles rather than reasoning to a hypothesis, then designing and executing an experiment to test it. Thus willingness to think critically needs mental energy and initiative. What can supply that energy? Love of inquiry, or perhaps just a habit of inquiry. Hamby (2015) has argued that willingness to inquire is the central critical thinking virtue, one that encompasses all the others. It is recognized as a critical thinking disposition by Dewey (1910: 29; 1933: 35), Glaser (1941: 5), Ennis (1987: 12; 1991: 8), Facione (1990a: 25), Bailin et al. (1999b: 294), Halpern (1998: 452), and Facione, Facione, & Giancarlo (2001).
• Self-confidence : Lack of confidence in one’s abilities can block critical thinking. For example, if the woman in Rash lacked confidence in her ability to figure things out for herself, she might just have assumed that the rash on her chest was the allergic reaction to her medication against which the pharmacist had warned her. Thus willingness to think critically requires confidence in one’s ability to inquire (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Courage : Fear of thinking for oneself can stop one from doing it. Thus willingness to think critically requires intellectual courage (Paul & Elder 2006: 16).
• Open-mindedness : A dogmatic attitude will impede thinking critically. For example, a person who adheres rigidly to a “pro-choice” position on the issue of the legal status of induced abortion is likely to be unwilling to consider seriously the issue of when in its development an unborn child acquires a moral right to life. Thus willingness to think critically requires open-mindedness, in the sense of a willingness to examine questions to which one already accepts an answer but which further evidence or reasoning might cause one to answer differently (Dewey 1933; Facione 1990a; Ennis 1991; Bailin et al. 1999b; Halpern 1998, Facione, Facione, & Giancarlo 2001). Paul (1981) emphasizes open-mindedness about alternative world-views, and recommends a dialectical approach to integrating such views as central to what he calls “strong sense” critical thinking.
• Willingness to suspend judgment : Premature closure on an initial solution will block critical thinking. Thus willingness to think critically requires a willingness to suspend judgment while alternatives are explored (Facione 1990a; Ennis 1991; Halpern 1998).
• Trust in reason : Since distrust in the processes of reasoned inquiry will dissuade one from engaging in it, trust in them is an initiating critical thinking disposition (Facione 1990a, 25; Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001; Paul & Elder 2006). In reaction to an allegedly exclusive emphasis on reason in critical thinking theory and pedagogy, Thayer-Bacon (2000) argues that intuition, imagination, and emotion have important roles to play in an adequate conception of critical thinking that she calls “constructive thinking”. From her point of view, critical thinking requires trust not only in reason but also in intuition, imagination, and emotion.
• Seeking the truth : If one does not care about the truth but is content to stick with one’s initial bias on an issue, then one will not think critically about it. Seeking the truth is thus an initiating critical thinking disposition (Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001). A disposition to seek the truth is implicit in more specific critical thinking dispositions, such as trying to be well-informed, considering seriously points of view other than one’s own, looking for alternatives, suspending judgment when the evidence is insufficient, and adopting a position when the evidence supporting it is sufficient.

Some of the initiating dispositions, such as open-mindedness and willingness to suspend judgment, are also internal critical thinking dispositions, in the sense of mental habits or attitudes that contribute causally to doing a good job of critical thinking once one starts the process. But there are many other internal critical thinking dispositions. Some of them are parasitic on one’s conception of good thinking. For example, it is constitutive of good thinking about an issue to formulate the issue clearly and to maintain focus on it. For this purpose, one needs not only the corresponding ability but also the corresponding disposition. Ennis (1991: 8) describes it as the disposition “to determine and maintain focus on the conclusion or question”, Facione (1990a: 25) as “clarity in stating the question or concern”. Other internal dispositions are motivators to continue or adjust the critical thinking process, such as willingness to persist in a complex task and willingness to abandon nonproductive strategies in an attempt to self-correct (Halpern 1998: 452). For a list of identified internal critical thinking dispositions, see the Supplement on Internal Critical Thinking Dispositions .

Some theorists postulate skills, i.e., acquired abilities, as operative in critical thinking. It is not obvious, however, that a good mental act is the exercise of a generic acquired skill. Inferring an expected time of arrival, as in Transit , has some generic components but also uses non-generic subject-matter knowledge. Bailin et al. (1999a) argue against viewing critical thinking skills as generic and discrete, on the ground that skilled performance at a critical thinking task cannot be separated from knowledge of concepts and from domain-specific principles of good thinking. Talk of skills, they concede, is unproblematic if it means merely that a person with critical thinking skills is capable of intelligent performance.

Despite such scepticism, theorists of critical thinking have listed as general contributors to critical thinking what they variously call abilities (Glaser 1941; Ennis 1962, 1991), skills (Facione 1990a; Halpern 1998) or competencies (Fisher & Scriven 1997). Amalgamating these lists would produce a confusing and chaotic cornucopia of more than 50 possible educational objectives, with only partial overlap among them. It makes sense instead to try to understand the reasons for the multiplicity and diversity, and to make a selection according to one’s own reasons for singling out abilities to be developed in a critical thinking curriculum. Two reasons for diversity among lists of critical thinking abilities are the underlying conception of critical thinking and the envisaged educational level. Appraisal-only conceptions, for example, involve a different suite of abilities than constructive-only conceptions. Some lists, such as those in (Glaser 1941), are put forward as educational objectives for secondary school students, whereas others are proposed as objectives for college students (e.g., Facione 1990a).

The abilities described in the remaining paragraphs of this section emerge from reflection on the general abilities needed to do well the thinking activities identified in section 6 as components of the critical thinking process described in section 5 . The derivation of each collection of abilities is accompanied by citation of sources that list such abilities and of standardized tests that claim to test them.

Observational abilities : Careful and accurate observation sometimes requires specialist expertise and practice, as in the case of observing birds and observing accident scenes. However, there are general abilities of noticing what one’s senses are picking up from one’s environment and of being able to articulate clearly and accurately to oneself and others what one has observed. It helps in exercising them to be able to recognize and take into account factors that make one’s observation less trustworthy, such as prior framing of the situation, inadequate time, deficient senses, poor observation conditions, and the like. It helps as well to be skilled at taking steps to make one’s observation more trustworthy, such as moving closer to get a better look, measuring something three times and taking the average, and checking what one thinks one is observing with someone else who is in a good position to observe it. It also helps to be skilled at recognizing respects in which one’s report of one’s observation involves inference rather than direct observation, so that one can then consider whether the inference is justified. These abilities come into play as well when one thinks about whether and with what degree of confidence to accept an observation report, for example in the study of history or in a criminal investigation or in assessing news reports. Observational abilities show up in some lists of critical thinking abilities (Ennis 1962: 90; Facione 1990a: 16; Ennis 1991: 9). There are items testing a person’s ability to judge the credibility of observation reports in the Cornell Critical Thinking Tests, Levels X and Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). Norris and King (1983, 1985, 1990a, 1990b) is a test of ability to appraise observation reports.

Emotional abilities : The emotions that drive a critical thinking process are perplexity or puzzlement, a wish to resolve it, and satisfaction at achieving the desired resolution. Children experience these emotions at an early age, without being trained to do so. Education that takes critical thinking as a goal needs only to channel these emotions and to make sure not to stifle them. Collaborative critical thinking benefits from ability to recognize one’s own and others’ emotional commitments and reactions.

Questioning abilities : A critical thinking process needs transformation of an inchoate sense of perplexity into a clear question. Formulating a question well requires not building in questionable assumptions, not prejudging the issue, and using language that in context is unambiguous and precise enough (Ennis 1962: 97; 1991: 9).

Imaginative abilities : Thinking directed at finding the correct causal explanation of a general phenomenon or particular event requires an ability to imagine possible explanations. Thinking about what policy or plan of action to adopt requires generation of options and consideration of possible consequences of each option. Domain knowledge is required for such creative activity, but a general ability to imagine alternatives is helpful and can be nurtured so as to become easier, quicker, more extensive, and deeper (Dewey 1910: 34–39; 1933: 40–47). Facione (1990a) and Halpern (1998) include the ability to imagine alternatives as a critical thinking ability.

Inferential abilities : The ability to draw conclusions from given information, and to recognize with what degree of certainty one’s own or others’ conclusions follow, is universally recognized as a general critical thinking ability. All 11 examples in section 2 of this article include inferences, some from hypotheses or options (as in Transit , Ferryboat and Disorder ), others from something observed (as in Weather and Rash ). None of these inferences is formally valid. Rather, they are licensed by general, sometimes qualified substantive rules of inference (Toulmin 1958) that rest on domain knowledge—that a bus trip takes about the same time in each direction, that the terminal of a wireless telegraph would be located on the highest possible place, that sudden cooling is often followed by rain, that an allergic reaction to a sulfa drug generally shows up soon after one starts taking it. It is a matter of controversy to what extent the specialized ability to deduce conclusions from premisses using formal rules of inference is needed for critical thinking. Dewey (1933) locates logical forms in setting out the products of reflection rather than in the process of reflection. Ennis (1981a), on the other hand, maintains that a liberally-educated person should have the following abilities: to translate natural-language statements into statements using the standard logical operators, to use appropriately the language of necessary and sufficient conditions, to deal with argument forms and arguments containing symbols, to determine whether in virtue of an argument’s form its conclusion follows necessarily from its premisses, to reason with logically complex propositions, and to apply the rules and procedures of deductive logic. Inferential abilities are recognized as critical thinking abilities by Glaser (1941: 6), Facione (1990a: 9), Ennis (1991: 9), Fisher & Scriven (1997: 99, 111), and Halpern (1998: 452). Items testing inferential abilities constitute two of the five subtests of the Watson Glaser Critical Thinking Appraisal (Watson & Glaser 1980a, 1980b, 1994), two of the four sections in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), three of the seven sections in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), 11 of the 34 items on Forms A and B of the California Critical Thinking Skills Test (Facione 1990b, 1992), and a high but variable proportion of the 25 selected-response questions in the Collegiate Learning Assessment (Council for Aid to Education 2017).

Experimenting abilities : Knowing how to design and execute an experiment is important not just in scientific research but also in everyday life, as in Rash . Dewey devoted a whole chapter of his How We Think (1910: 145–156; 1933: 190–202) to the superiority of experimentation over observation in advancing knowledge. Experimenting abilities come into play at one remove in appraising reports of scientific studies. Skill in designing and executing experiments includes the acknowledged abilities to appraise evidence (Glaser 1941: 6), to carry out experiments and to apply appropriate statistical inference techniques (Facione 1990a: 9), to judge inductions to an explanatory hypothesis (Ennis 1991: 9), and to recognize the need for an adequately large sample size (Halpern 1998). The Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) includes four items (out of 52) on experimental design. The Collegiate Learning Assessment (Council for Aid to Education 2017) makes room for appraisal of study design in both its performance task and its selected-response questions.

Consulting abilities : Skill at consulting sources of information comes into play when one seeks information to help resolve a problem, as in Candidate . Ability to find and appraise information includes ability to gather and marshal pertinent information (Glaser 1941: 6), to judge whether a statement made by an alleged authority is acceptable (Ennis 1962: 84), to plan a search for desired information (Facione 1990a: 9), and to judge the credibility of a source (Ennis 1991: 9). Ability to judge the credibility of statements is tested by 24 items (out of 76) in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) and by four items (out of 52) in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). The College Learning Assessment’s performance task requires evaluation of whether information in documents is credible or unreliable (Council for Aid to Education 2017).

Argument analysis abilities : The ability to identify and analyze arguments contributes to the process of surveying arguments on an issue in order to form one’s own reasoned judgment, as in Candidate . The ability to detect and analyze arguments is recognized as a critical thinking skill by Facione (1990a: 7–8), Ennis (1991: 9) and Halpern (1998). Five items (out of 34) on the California Critical Thinking Skills Test (Facione 1990b, 1992) test skill at argument analysis. The College Learning Assessment (Council for Aid to Education 2017) incorporates argument analysis in its selected-response tests of critical reading and evaluation and of critiquing an argument.

Judging skills and deciding skills : Skill at judging and deciding is skill at recognizing what judgment or decision the available evidence and argument supports, and with what degree of confidence. It is thus a component of the inferential skills already discussed.

Lists and tests of critical thinking abilities often include two more abilities: identifying assumptions and constructing and evaluating definitions.

In addition to dispositions and abilities, critical thinking needs knowledge: of critical thinking concepts, of critical thinking principles, and of the subject-matter of the thinking.

We can derive a short list of concepts whose understanding contributes to critical thinking from the critical thinking abilities described in the preceding section. Observational abilities require an understanding of the difference between observation and inference. Questioning abilities require an understanding of the concepts of ambiguity and vagueness. Inferential abilities require an understanding of the difference between conclusive and defeasible inference (traditionally, between deduction and induction), as well as of the difference between necessary and sufficient conditions. Experimenting abilities require an understanding of the concepts of hypothesis, null hypothesis, assumption and prediction, as well as of the concept of statistical significance and of its difference from importance. They also require an understanding of the difference between an experiment and an observational study, and in particular of the difference between a randomized controlled trial, a prospective correlational study and a retrospective (case-control) study. Argument analysis abilities require an understanding of the concepts of argument, premiss, assumption, conclusion and counter-consideration. Additional critical thinking concepts are proposed by Bailin et al. (1999b: 293), Fisher & Scriven (1997: 105–106), and Black (2012).

According to Glaser (1941: 25), ability to think critically requires knowledge of the methods of logical inquiry and reasoning. If we review the list of abilities in the preceding section, however, we can see that some of them can be acquired and exercised merely through practice, possibly guided in an educational setting, followed by feedback. Searching intelligently for a causal explanation of some phenomenon or event requires that one consider a full range of possible causal contributors, but it seems more important that one implements this principle in one’s practice than that one is able to articulate it. What is important is “operational knowledge” of the standards and principles of good thinking (Bailin et al. 1999b: 291–293). But the development of such critical thinking abilities as designing an experiment or constructing an operational definition can benefit from learning their underlying theory. Further, explicit knowledge of quirks of human thinking seems useful as a cautionary guide. Human memory is not just fallible about details, as people learn from their own experiences of misremembering, but is so malleable that a detailed, clear and vivid recollection of an event can be a total fabrication (Loftus 2017). People seek or interpret evidence in ways that are partial to their existing beliefs and expectations, often unconscious of their “confirmation bias” (Nickerson 1998). Not only are people subject to this and other cognitive biases (Kahneman 2011), of which they are typically unaware, but it may be counter-productive for one to make oneself aware of them and try consciously to counteract them or to counteract social biases such as racial or sexual stereotypes (Kenyon & Beaulac 2014). It is helpful to be aware of these facts and of the superior effectiveness of blocking the operation of biases—for example, by making an immediate record of one’s observations, refraining from forming a preliminary explanatory hypothesis, blind refereeing, double-blind randomized trials, and blind grading of students’ work.

Critical thinking about an issue requires substantive knowledge of the domain to which the issue belongs. Critical thinking abilities are not a magic elixir that can be applied to any issue whatever by somebody who has no knowledge of the facts relevant to exploring that issue. For example, the student in Bubbles needed to know that gases do not penetrate solid objects like a glass, that air expands when heated, that the volume of an enclosed gas varies directly with its temperature and inversely with its pressure, and that hot objects will spontaneously cool down to the ambient temperature of their surroundings unless kept hot by insulation or a source of heat. Critical thinkers thus need a rich fund of subject-matter knowledge relevant to the variety of situations they encounter. This fact is recognized in the inclusion among critical thinking dispositions of a concern to become and remain generally well informed.

Experimental educational interventions, with control groups, have shown that education can improve critical thinking skills and dispositions, as measured by standardized tests. For information about these tests, see the Supplement on Assessment .

What educational methods are most effective at developing the dispositions, abilities and knowledge of a critical thinker? Abrami et al. (2015) found that in the experimental and quasi-experimental studies that they analyzed dialogue, anchored instruction, and mentoring each increased the effectiveness of the educational intervention, and that they were most effective when combined. They also found that in these studies a combination of separate instruction in critical thinking with subject-matter instruction in which students are encouraged to think critically was more effective than either by itself. However, the difference was not statistically significant; that is, it might have arisen by chance.

Most of these studies lack the longitudinal follow-up required to determine whether the observed differential improvements in critical thinking abilities or dispositions continue over time, for example until high school or college graduation. For details on studies of methods of developing critical thinking skills and dispositions, see the Supplement on Educational Methods .

12. Controversies

Scholars have denied the generalizability of critical thinking abilities across subject domains, have alleged bias in critical thinking theory and pedagogy, and have investigated the relationship of critical thinking to other kinds of thinking.

McPeck (1981) attacked the thinking skills movement of the 1970s, including the critical thinking movement. He argued that there are no general thinking skills, since thinking is always thinking about some subject-matter. It is futile, he claimed, for schools and colleges to teach thinking as if it were a separate subject. Rather, teachers should lead their pupils to become autonomous thinkers by teaching school subjects in a way that brings out their cognitive structure and that encourages and rewards discussion and argument. As some of his critics (e.g., Paul 1985; Siegel 1985) pointed out, McPeck’s central argument needs elaboration, since it has obvious counter-examples in writing and speaking, for which (up to a certain level of complexity) there are teachable general abilities even though they are always about some subject-matter. To make his argument convincing, McPeck needs to explain how thinking differs from writing and speaking in a way that does not permit useful abstraction of its components from the subject-matters with which it deals. He has not done so. Nevertheless, his position that the dispositions and abilities of a critical thinker are best developed in the context of subject-matter instruction is shared by many theorists of critical thinking, including Dewey (1910, 1933), Glaser (1941), Passmore (1980), Weinstein (1990), and Bailin et al. (1999b).

McPeck’s challenge prompted reflection on the extent to which critical thinking is subject-specific. McPeck argued for a strong subject-specificity thesis, according to which it is a conceptual truth that all critical thinking abilities are specific to a subject. (He did not however extend his subject-specificity thesis to critical thinking dispositions. In particular, he took the disposition to suspend judgment in situations of cognitive dissonance to be a general disposition.) Conceptual subject-specificity is subject to obvious counter-examples, such as the general ability to recognize confusion of necessary and sufficient conditions. A more modest thesis, also endorsed by McPeck, is epistemological subject-specificity, according to which the norms of good thinking vary from one field to another. Epistemological subject-specificity clearly holds to a certain extent; for example, the principles in accordance with which one solves a differential equation are quite different from the principles in accordance with which one determines whether a painting is a genuine Picasso. But the thesis suffers, as Ennis (1989) points out, from vagueness of the concept of a field or subject and from the obvious existence of inter-field principles, however broadly the concept of a field is construed. For example, the principles of hypothetico-deductive reasoning hold for all the varied fields in which such reasoning occurs. A third kind of subject-specificity is empirical subject-specificity, according to which as a matter of empirically observable fact a person with the abilities and dispositions of a critical thinker in one area of investigation will not necessarily have them in another area of investigation.

The thesis of empirical subject-specificity raises the general problem of transfer. If critical thinking abilities and dispositions have to be developed independently in each school subject, how are they of any use in dealing with the problems of everyday life and the political and social issues of contemporary society, most of which do not fit into the framework of a traditional school subject? Proponents of empirical subject-specificity tend to argue that transfer is more likely to occur if there is critical thinking instruction in a variety of domains, with explicit attention to dispositions and abilities that cut across domains. But evidence for this claim is scanty. There is a need for well-designed empirical studies that investigate the conditions that make transfer more likely.

It is common ground in debates about the generality or subject-specificity of critical thinking dispositions and abilities that critical thinking about any topic requires background knowledge about the topic. For example, the most sophisticated understanding of the principles of hypothetico-deductive reasoning is of no help unless accompanied by some knowledge of what might be plausible explanations of some phenomenon under investigation.

Critics have objected to bias in the theory, pedagogy and practice of critical thinking. Commentators (e.g., Alston 1995; Ennis 1998) have noted that anyone who takes a position has a bias in the neutral sense of being inclined in one direction rather than others. The critics, however, are objecting to bias in the pejorative sense of an unjustified favoring of certain ways of knowing over others, frequently alleging that the unjustly favoured ways are those of a dominant sex or culture (Bailin 1995). These ways favour:

• reinforcement of egocentric and sociocentric biases over dialectical engagement with opposing world-views (Paul 1981, 1984; Warren 1998)
• distancing from the object of inquiry over closeness to it (Martin 1992; Thayer-Bacon 1992)
• indifference to the situation of others over care for them (Martin 1992)
• orientation to thought over orientation to action (Martin 1992)
• being reasonable over caring to understand people’s ideas (Thayer-Bacon 1993)
• being neutral and objective over being embodied and situated (Thayer-Bacon 1995a)
• doubting over believing (Thayer-Bacon 1995b)
• reason over emotion, imagination and intuition (Thayer-Bacon 2000)
• solitary thinking over collaborative thinking (Thayer-Bacon 2000)
• written and spoken assignments over other forms of expression (Alston 2001)
• attention to written and spoken communications over attention to human problems (Alston 2001)
• winning debates in the public sphere over making and understanding meaning (Alston 2001)

A common thread in this smorgasbord of accusations is dissatisfaction with focusing on the logical analysis and evaluation of reasoning and arguments. While these authors acknowledge that such analysis and evaluation is part of critical thinking and should be part of its conceptualization and pedagogy, they insist that it is only a part. Paul (1981), for example, bemoans the tendency of atomistic teaching of methods of analyzing and evaluating arguments to turn students into more able sophists, adept at finding fault with positions and arguments with which they disagree but even more entrenched in the egocentric and sociocentric biases with which they began. Martin (1992) and Thayer-Bacon (1992) cite with approval the self-reported intimacy with their subject-matter of leading researchers in biology and medicine, an intimacy that conflicts with the distancing allegedly recommended in standard conceptions and pedagogy of critical thinking. Thayer-Bacon (2000) contrasts the embodied and socially embedded learning of her elementary school students in a Montessori school, who used their imagination, intuition and emotions as well as their reason, with conceptions of critical thinking as

thinking that is used to critique arguments, offer justifications, and make judgments about what are the good reasons, or the right answers. (Thayer-Bacon 2000: 127–128)

Alston (2001) reports that her students in a women’s studies class were able to see the flaws in the Cinderella myth that pervades much romantic fiction but in their own romantic relationships still acted as if all failures were the woman’s fault and still accepted the notions of love at first sight and living happily ever after. Students, she writes, should

be able to connect their intellectual critique to a more affective, somatic, and ethical account of making risky choices that have sexist, racist, classist, familial, sexual, or other consequences for themselves and those both near and far… critical thinking that reads arguments, texts, or practices merely on the surface without connections to feeling/desiring/doing or action lacks an ethical depth that should infuse the difference between mere cognitive activity and something we want to call critical thinking. (Alston 2001: 34)

Some critics portray such biases as unfair to women. Thayer-Bacon (1992), for example, has charged modern critical thinking theory with being sexist, on the ground that it separates the self from the object and causes one to lose touch with one’s inner voice, and thus stigmatizes women, who (she asserts) link self to object and listen to their inner voice. Her charge does not imply that women as a group are on average less able than men to analyze and evaluate arguments. Facione (1990c) found no difference by sex in performance on his California Critical Thinking Skills Test. Kuhn (1991: 280–281) found no difference by sex in either the disposition or the competence to engage in argumentative thinking.

The critics propose a variety of remedies for the biases that they allege. In general, they do not propose to eliminate or downplay critical thinking as an educational goal. Rather, they propose to conceptualize critical thinking differently and to change its pedagogy accordingly. Their pedagogical proposals arise logically from their objections. They can be summarized as follows:

• Focus on argument networks with dialectical exchanges reflecting contesting points of view rather than on atomic arguments, so as to develop “strong sense” critical thinking that transcends egocentric and sociocentric biases (Paul 1981, 1984).
• Foster closeness to the subject-matter and feeling connected to others in order to inform a humane democracy (Martin 1992).
• Develop “constructive thinking” as a social activity in a community of physically embodied and socially embedded inquirers with personal voices who value not only reason but also imagination, intuition and emotion (Thayer-Bacon 2000).
• In developing critical thinking in school subjects, treat as important neither skills nor dispositions but opening worlds of meaning (Alston 2001).
• Attend to the development of critical thinking dispositions as well as skills, and adopt the “critical pedagogy” practised and advocated by Freire (1968 [1970]) and hooks (1994) (Dalgleish, Girard, & Davies 2017).

A common thread in these proposals is treatment of critical thinking as a social, interactive, personally engaged activity like that of a quilting bee or a barn-raising (Thayer-Bacon 2000) rather than as an individual, solitary, distanced activity symbolized by Rodin’s The Thinker . One can get a vivid description of education with the former type of goal from the writings of bell hooks (1994, 2010). Critical thinking for her is open-minded dialectical exchange across opposing standpoints and from multiple perspectives, a conception similar to Paul’s “strong sense” critical thinking (Paul 1981). She abandons the structure of domination in the traditional classroom. In an introductory course on black women writers, for example, she assigns students to write an autobiographical paragraph about an early racial memory, then to read it aloud as the others listen, thus affirming the uniqueness and value of each voice and creating a communal awareness of the diversity of the group’s experiences (hooks 1994: 84). Her “engaged pedagogy” is thus similar to the “freedom under guidance” implemented in John Dewey’s Laboratory School of Chicago in the late 1890s and early 1900s. It incorporates the dialogue, anchored instruction, and mentoring that Abrami (2015) found to be most effective in improving critical thinking skills and dispositions.

What is the relationship of critical thinking to problem solving, decision-making, higher-order thinking, creative thinking, and other recognized types of thinking? One’s answer to this question obviously depends on how one defines the terms used in the question. If critical thinking is conceived broadly to cover any careful thinking about any topic for any purpose, then problem solving and decision making will be kinds of critical thinking, if they are done carefully. Historically, ‘critical thinking’ and ‘problem solving’ were two names for the same thing. If critical thinking is conceived more narrowly as consisting solely of appraisal of intellectual products, then it will be disjoint with problem solving and decision making, which are constructive.

Bloom’s taxonomy of educational objectives used the phrase “intellectual abilities and skills” for what had been labeled “critical thinking” by some, “reflective thinking” by Dewey and others, and “problem solving” by still others (Bloom et al. 1956: 38). Thus, the so-called “higher-order thinking skills” at the taxonomy’s top levels of analysis, synthesis and evaluation are just critical thinking skills, although they do not come with general criteria for their assessment (Ennis 1981b). The revised version of Bloom’s taxonomy (Anderson et al. 2001) likewise treats critical thinking as cutting across those types of cognitive process that involve more than remembering (Anderson et al. 2001: 269–270). For details, see the Supplement on History .

As to creative thinking, it overlaps with critical thinking (Bailin 1987, 1988). Thinking about the explanation of some phenomenon or event, as in Ferryboat , requires creative imagination in constructing plausible explanatory hypotheses. Likewise, thinking about a policy question, as in Candidate , requires creativity in coming up with options. Conversely, creativity in any field needs to be balanced by critical appraisal of the draft painting or novel or mathematical theory.
