Critical thinking

Monkey contemplating the pseudoscientific nature of homeopathy

Having the skills to think critically about new information is a vital skill in the modern era. Without it, people are subject to grift, pseudoscience, conspiracy, and misinformation.

Critical thinking is often confused with being contrarian. These are not the same thing. A contrarian may offer some valid criticisms of an out-group, but will not concede any valid points they make.

The meaning of critical thinking and skepticism has been muddied in recent years by conspiracy theorists, racists and misogynists, and other misinformation peddlers who employ the language of critical thinking to what is actually institutional contrarianism.

True critical thinking is open to the evaluation of new evidence and willing to change positions if that evidence warrants it, regardless of in-group affiliation.

See Critical Thinking and Reason on Wikipedia. Also related is Logic.

Communicative Rationality is the theory that rationality is the inevitable outcome of successful communication, and that rationality is a built-in property of language. Yuval Noah Harari's book Nexus suggests otherwise, pointing to many cases throughout history where technologies that improve our ability to communicate have led to the spread of misinformation and authoritarian abuses of power. One could argue that these simply represent unsuccessful attempts at communication. In any case, regardless of whether progress trends toward reason because it is inevitable, or because we choose reason over misinformation, or because we inevitably choose reason due to determinism, we should still make that choice.

Thinking is Power has great free courses that teach critical thinking skills.
