The Art of Thinking Clearly

Rolf Dobelli identifies ninety-nine common cognitive biases that distort human judgment and decision-making. The book classifies irrational behaviors like the sunk cost fallacy, where individuals persist in failing ventures because they have already invested resources, and the confirmation bias, which leads people to ignore evidence that contradicts their existing beliefs. Dobelli uses psychological frameworks such as social proof and the scarcity error to explain why brains developed these shortcuts for survival and why they frequently fail in modern, complex environments.

This guide targets professionals and practitioners looking to refine their logic and productivity.
