Why it’s on the shelf

A field guide to the 99 mental potholes your brain hits daily, because in a world of noise, avoiding stupidity beats chasing brilliance.

Two of the ideas you’ll keep

The Clif summary of The Art of Thinking Clearly pulls out 7 insights. Here are the first two.

  1. Survivorship bias inflates our sense of the odds because we only ever see the winners. For every celebrated founder or hit musician, a silent graveyard of identical-looking failures goes unreported, so Dobelli advises deliberately visiting the 'cemetery' of dead projects before betting on your own.
  2. The swimmer's body illusion confuses a selection factor with a result. Elite swimmers aren't lean because they train; they were pre-selected for the sport because they were already lean. Universities, diets, and MBAs sell you the illusion, so always ask what was being screened for.

The other 5 — and the full 11-minute summary — are in the app.
