â€śBrilliant. . . . Lewis has given us a spectacular account of two great men who faced up to uncertainty and the limits of human reason.â€ť â€•William Easterly, Wall Street JournalForty years ago, Israeli psychologists Daniel Kahneman and Amos Tversky wrote a series of breathtakingly original papers that invented the field of behavioral economics. One of the greatest partnerships in the history of science, Kahneman and Tverskyâ€™s extraordinary friendship incited a revolution in Big Data studies, advanced evidence-based medicine, led to a new approach to government regulation, and made much of Michael Lewisâ€™s own work possible. In The Undoing Project, Lewis shows how their Nobel Prizeâ€“winning theory of the mind altered our perception of reality.
