Bestselling writer Michael Lewis examines how a Nobel Prize-winning theory of the mind altered our perception of reality.

Forty years back, Israeli psychologists Daniel Kahneman and Amos Tversky wrote some breathtakingly original studies undoing our assumptions on the subject of the decision-making process. Their documents showed the ways in which the human mind erred, systematically, when pressured to create judgments about uncertain situations. Their work developed the field of behavioral economics, about The Undoing Project: A Friendship that Changed Our Thoughts revolutionized Big Data research, advanced evidence-based medication, led to a new approach to federal government regulation, and produced a lot of Michael Lewis’s personal work possible. Kahneman and Tversky are even more accountable than anybody for the effective trend to mistrust individual intuition and defer to algorithms.

The Undoing Task is approximately the fascinating collaboration between two men who have the dimensions of great literary figures. They truly became heroes in the university and on the battlefield―both experienced important careers in the Israeli armed service―and their study was deeply associated with their extraordinary life experiences. Along the way they may well have changed, for good, mankind’s view of its mind.
