The Undoing Project: A Friendship That Changed Our Minds

Michael Lewis chronicles the unlikely and transformative partnership between psychologists Daniel Kahneman and Amos Tversky, two men whose personalities and backgrounds could not have been more different. Through their collaboration, they dismantled the prevailing economic assumption that humans are rational actors, revealing instead that our decision-making is riddled with systematic biases and cognitive errors. The book traces their journey from initial skepticism to a shared obsession with understanding the flaws in human judgment, a pursuit that ultimately reshaped fields ranging from economics to public policy.

Lewis writes with his characteristic narrative flair, blending biographical detail with accessible explanations of complex psychological concepts. The prose is engaging and conversational, making dense ideas about probability and risk intuitive for a general audience. By focusing on the human dynamic between the two protagonists, the book serves as both a history of behavioral economics and a study in the power of intellectual friendship.
