What this book is about
Daniel Kahneman and Amos Tversky were Israeli psychologists who spent twenty years together mapping the systematic errors in human judgment — the cognitive biases that affect doctors, generals, economists, and everyone else. Their friendship was intense and strange, and it produced Thinking, Fast and Slow and the entire field of behavioral economics. Michael Lewis tells the story of their collaboration, their bond, and the rivalry that eventually pulled them apart. Intellectual history that reads like a thriller.
