Should Critical Thinking be a Require Course? 10 Reasons

The Short Answer

Critical thinking should be a required course because the ability to analyze information, evaluate evidence, recognize logical fallacies, and reason through complex problems is foundational to every academic discipline, every professional field, and informed civic life. It is one of the most consistently cited skills in employer research, and yet most educational curricula treat it as something students absorb by osmosis rather than something that can and should be directly taught.

Teaching critical thinking explicitly produces better reasoners than hoping students absorb it while studying other things.

Here are ten reasons it belongs in the required curriculum.

1. It Teaches Students to Evaluate Evidence Rather Than Accept Claims

The ability to assess the quality of evidence behind a claim — to distinguish between strong evidence and weak evidence, between correlation and causation, between a credible source and a misleading one — is not intuitive. It is a skill that must be learned and practiced.

A required critical thinking course teaches students the difference between anecdotal and statistical evidence, how to assess the credibility and methodology of sources, how to identify when a study’s conclusions extend beyond what the data actually shows, and how to recognize the difference between a reasoned argument and an appeal to emotion. These skills change how students engage with every other subject.

2. It Reduces Susceptibility to Misinformation

Misinformation spreads efficiently in high-volume information environments because most people are not trained to evaluate the source, logic, or evidence quality of what they encounter. Critical thinking education directly addresses this by teaching students to ask the right questions before accepting and repeating claims.

Students who understand logical fallacies, propaganda techniques, confirmation bias, and motivated reasoning are better equipped to recognize when they are being manipulated — whether by social media, advertising, political communication, or poor-quality journalism. This is not a minor skill in an environment where false information travels faster than corrections.

3. It Improves Decision-Making in Every Area of Life

The techniques of critical thinking — clarifying the actual question being asked, identifying relevant evidence, considering alternative explanations, evaluating consequences — are applicable to every domain of human decision-making: career choices, financial decisions, relationship evaluations, health decisions, and civic choices.

People who have been explicitly trained in structured reasoning make measurably better decisions in domains with complex trade-offs and incomplete information. This is not surprising: decision-making is a skill, and like all skills, it improves with appropriate instruction and practice.

4. Employers Consistently Rank It Among the Most Valued Skills

Surveys of employers across industries consistently place critical thinking, problem-solving, and analytical reasoning at the top of the skills they want in employees — above most specific technical skills. The reason is straightforward: technical skills become outdated; the ability to think clearly about new problems does not.

A required critical thinking course directly addresses one of the most consistent gaps between what employers want from graduates and what educational systems typically produce.

5. It Supports Success Across All Academic Disciplines

Critical thinking is not a standalone subject that exists separately from other disciplines — it is the cognitive foundation on which all disciplines rest. A student who can reason clearly about evidence and argument will write better essays, conduct better science experiments, analyze historical sources more accurately, and engage with mathematical proofs more effectively.

Explicitly teaching the structure of an argument, how to evaluate a source, and how to identify a logical error benefits students in every course they take afterward. It is one of the highest-leverage courses a curriculum can include precisely because its benefits compound across every other subject.

6. It Teaches Students to Recognize Their Own Cognitive Biases

Human cognition is subject to systematic biases — confirmation bias, availability bias, anchoring, the sunk cost fallacy, and many others — that affect reasoning in predictable ways. Most people are unaware of these biases and therefore cannot compensate for them.

Critical thinking courses explicitly teach the most common cognitive biases and the conditions under which they operate. This awareness does not eliminate bias — nothing does entirely — but it gives students the tools to catch themselves when a bias is likely affecting their thinking and to take deliberate corrective steps.

7. It Is a Foundation for Ethical Reasoning

Ethical reasoning — working through the competing values, consequences, and principles that bear on a difficult moral decision — is itself a form of critical thinking applied to questions of right and wrong. A critical thinking course that includes formal ethics topics helps students develop a framework for thinking through ethical problems they will encounter in professional and personal life.

Many professions involve regular ethical decisions: healthcare, law, business, engineering, education, and public service all include situations where clear reasoning about competing values matters enormously. Training students in structured ethical reasoning prepares them to navigate those situations more thoughtfully.

8. It Prepares Students for Civic and Democratic Participation

Healthy democracy depends on an informed citizenry that can evaluate the claims of politicians, assess policy proposals, recognize propaganda, and make reasoned judgments about who should govern and why. These are all applications of critical thinking.

A required course in critical thinking is, in part, civic education — preparation for participation in democratic processes that require evaluating competing claims, assessing credibility, and reasoning through complex policy trade-offs.

9. It Cannot Be Effectively Replaced by Other Courses Alone

The standard argument against a required critical thinking course is that students develop these skills through other disciplines — science teaches empirical reasoning, English teaches argumentation, history teaches source analysis. This is partly true, but it overlooks a fundamental limitation: skills taught within disciplines are often not recognized as transferable by students.

A student who learns to evaluate historical sources in a history class may not spontaneously apply that same critical lens to a news article, a political claim, or a medical recommendation. Explicit instruction in the general principles of critical reasoning — taught as its own subject, applied across multiple domains — produces more transferable skill development than hoping students abstract these principles from discipline-specific instruction.

10. It Has Demonstrable Positive Effects on Academic Performance

Students who take formal critical thinking instruction demonstrate measurable improvements in academic performance across other courses, including writing quality, scientific reasoning, mathematical problem-solving, and reading comprehension. The skills of critical thinking are broadly enabling — they improve performance in other subjects because they improve the quality of the thinking applied to those subjects.

The evidence for including critical thinking as a required course — in terms of both the skills it develops and the outcomes it produces — is strong enough that the question is less “should it be required” and more “why hasn’t it been yet.” For related discussions on what should be in school curricula, why cooking should be taught in schools and why school itself is important explore adjacent questions about what education should accomplish.
