This is a broad and demanding book on judgment, heuristics, bias, and decision-making. It is not a startup manual, and some of the research discussed has been debated or refined, but it remains highly valuable for understanding overconfidence, anchoring, loss aversion, availability, and narrative bias.
Readers learn why coherent stories feel more certain than the evidence warrants, why founders overweight recent or memorable information, and why mentors should actively seek disconfirming evidence.
