Summary
The Undoing Project tells the story of the extraordinary collaboration between psychologists Daniel Kahneman and Amos Tversky, whose pioneering work on cognitive biases and heuristics transformed economics, medicine, and public policy. Lewis traces their unlikely friendship — the cautious, self-doubting Kahneman and the brash, confident Tversky — and shows how their intellectual chemistry produced breakthrough discoveries about how humans actually make decisions. Their work on prospect theory, anchoring, availability bias, and the representativeness heuristic challenged the rational actor model that dominated economics for centuries. The book explores how their findings influenced everything from medical diagnostics to NBA draft strategies, while also chronicling the personal tensions that eventually strained their partnership. Lewis reveals how two outsiders from Israel reshaped our understanding of the human mind.
Key takeaways
- Human judgment is systematically biased in predictable ways
- Prospect theory shows people fear losses more than they value equivalent gains
- Intellectual collaboration can produce insights neither partner could achieve alone
- Cognitive biases affect decisions in medicine, law, business, and everyday life
- The rational actor model in economics fundamentally misunderstands human behavior
