The Art of Thinking Clearly — the big ideas

Ninety-nine short chapters, each on one recurring reasoning error.

Free — no account needed to read

The big ideas

Survivorship bias gets the clearest treatment: you see the successes because the failures are not around to be counted, which distorts almost every lesson drawn from examples.

The sunk cost trap — continuing because of what has already been spent — is treated as the single most expensive everyday error, and the only relevant question is always what happens from here.

Its format is the point: short, self-contained, designed to be recognised in the moment rather than understood in theory.

Practise it — no need to have read it

Find a success story that has influenced a decision of yours. Ask how many people tried the same thing, and where they are now.

A hint: If you cannot find out, that is itself the answer about how much the story should weigh.

Where it shows up in real life

  • Investment decisions
  • Career advice from successful people
  • Continuing a project

Described in our own words with the source named — never quoted, and not a substitute for reading the book.
