Most people think they think critically — and mostly run on autopilot. This module defines what critical thinking actually is, the two systems your brain reasons with, why intellectual humility beats raw intelligence, and the dispositions that separate clear thinkers from clever ones.

Not all evidence is equal, and not all sources deserve your trust. This module covers how to weigh evidence by quality rather than quantity, judge a source's credibility, tell correlation from causation, and use base rates so a single vivid story doesn't override the numbers.

The biggest threat to your reasoning is your own brain, working exactly as designed. This module covers confirmation bias and motivated reasoning, the logical fallacies that wreck arguments, the heuristics that mislead, and the practical defences against being manipulated.

Hard problems feel overwhelming because they're unstructured. This module gives you the tools to impose structure: reasoning from first principles, breaking problems into MECE issue trees, mapping arguments to find the real disagreement, and steelmanning the other side.

Clear thinking in a quiet room is one thing; thinking clearly under deadline, in a heated meeting, or in a biased group is another. This final module covers fast-but-sound reasoning under pressure, thinking well in groups, and building a critical-thinking practice that lasts.
