Critical thinking
Critical thinking is the disciplined process of analysing and evaluating information, arguments and evidence in order to form a well-reasoned, justified judgement.
The step most authors miss
Doing CRediT right? Don’t stop at the statement.
A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.
Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.
The core skills
Critical thinking draws on a recognisable set of intellectual skills: interpreting what a claim actually means, analysing how an argument is structured, evaluating the quality of evidence and inferences, drawing reasonable conclusions, and explaining one’s reasoning clearly. A central component is the ability to distinguish sound reasoning from fallacious reasoning — spotting ad hominems, false dichotomies, hasty generalisations and the like. These skills apply across disciplines, which is why critical thinking is treated as a general educational goal rather than the property of any single subject.
Dispositions, not just techniques
Beyond technique, critical thinking depends on dispositions — habits of mind such as intellectual humility, open-mindedness, fair-mindedness and a willingness to question one’s own assumptions. A skilled reasoner who only ever uses those skills to defend a predetermined conclusion is engaged in rationalisation, not critical thinking. The genuine article requires being prepared to revise or abandon a belief when the evidence warrants it. This combination of capability and character is what educational frameworks mean when they describe the "critical spirit".
Why it matters
Critical thinking underpins sound decision-making, research integrity and informed citizenship. It allows a person to assess the reliability of sources, recognise manipulation and rhetoric, and reason from evidence rather than from impulse or authority. In academic work it supports evaluating studies, detecting weak arguments and constructing defensible claims of one’s own. Because misinformation and persuasive but flawed reasoning are pervasive, the ability to think critically is widely regarded as one of the most transferable and durable skills a person can develop.

Common misconceptions
What people often get wrong
Often heard: Critical thinking means criticising and finding fault with everything.
Actually: Critical thinking is not mere negativity. The word "critical" derives from evaluating and judging carefully, which includes recognising strong arguments as well as weak ones. A critical thinker gives credit to good reasoning and evidence, not only objections.
Often heard: Critical thinking is an innate talent you either have or do not.
Actually: Critical thinking is a learnable, trainable set of skills and habits. Like any skill it improves with deliberate practice — analysing arguments, studying fallacies and seeking feedback. It is widely taught precisely because it can be developed rather than being fixed at birth.
Often heard: Being intelligent automatically makes someone a good critical thinker.
Actually: Intelligence and critical thinking are related but distinct. Highly intelligent people can still reason carelessly, fall for fallacies or defend conclusions they have not examined. Critical thinking requires the disposition to question one’s own views, which intelligence alone does not guarantee.
