By the author of Moneyball and The Big Short, this is the story of the lives of Amos Tversky and Daniel Kahneman, and their contributions to the psychology underlying how people make decisions. Tversky and Kahneman grew up in Israel, and started their work there before eventually migrating to the US. While so different in personality, initially they were able to overcome this and collaborated very productively, but eventually these differences took their toll and they parted ways. The book is an interesting biography, as well as capturing many of their key contributions to the science of decision-making.
