In "The Undoing Project," Michael Lewis explores the deep friendship between psychologists Daniel Kahneman and Amos Tversky, which revolutionized the understanding of human decision-making. Their collaboration led to significant insights into how people assess risks and make choices, challenging traditional economic theories that assumed rational behavior. Through their research, they elucidated the cognitive biases that often lead to irrational decisions.

Morey emphasizes that knowledge fundamentally enhances our ability to anticipate outcomes. By framing knowledge as a tool for better predictions, it becomes clear that the essence of understanding lies in improving our foresight. This perspective highlights the importance of psychological research in equipping individuals and societies to navigate uncertainties effectively.
