The Undoing Project is an astonishing exploration of the relationship between these two brilliant psychologists, who changed how we understand human behavior. In 1971, Daniel Kahneman and Amos Tversky wrote a series of breathtakingly original papers that invented the field of behavioral economics. One of the most significant partnerships in the history of science, their 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 Lewis’s work possible.

It was a partnership that revolutionized the study of the human mind: Amos Tversky and Daniel Kahneman, who worked at Hebrew University in Jerusalem during the seventies and eighties, pioneered the field of behavioral economics. They also made significant contributions to evidence-based medicine. Their friendship would forever shape their ideas about judgment, decision-making, belief perseverance, and having confidence in themselves when others doubt them.

The friendship of two Israeli psychologists helped transform how we understand the human mind. A true masterpiece of scientific and intellectual storytelling, The Undoing Project is a revelatory examination of the relationship between Daniel Kahneman and Amos Tversky — two academics whose groundbreaking collaboration on the science of making predictions led to a new understanding of how people make decisions.

About The Undoing Project Book

Forty 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 Tversky’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 Lewis’s own work possible. In The Undoing Project, Lewis shows how their Nobel Prize–winning theory of the mind altered our perception of reality.

The Undoing Project is a lucid, riveting, and often funny account of the friendship between the Israeli psychologists Amos Tversky and Danny Kahneman. It is also a story of friendship itself: how two young men with radically different personalities became an unbeatable team. This work of non-fiction would be gripping if it were fiction. It is hard to believe that a book can be so compelling and so careful simultaneously.”
