In this five-minute exploration, we unpack the key lessons from The Undoing Project: A Friendship That Changed Our Minds by Michael Lewis—a fascinating narrative of how two psychologists, Daniel Kahneman and Amos Tversky, uncovered the quirks of the human mind and transformed how we think about decisions, risk and behaviour. Whether you’re curious about psychology, decision-making or human nature—this episode gives you a powerful lens to understand yourself and others better.
We begin by laying out the pair’s partnership and pioneering work in behavioural economics—how they challenged the assumption that humans are rational actors and revealed systematic patterns in how we err.
Then we explore heuristics and anomalies—the mental shortcuts we use and the errors they create. Kahneman and Tversky identified how our minds deceive us, consistently. The story brings those ideas to life.
Next, we examine the intersection of friendship, research and impact—how their collaboration produced insights that changed fields ranging from economics to medicine to public policy. The human story behind the science makes it compelling and accessible.
Fourth, we draw practical lessons: how you can apply their insights to your daily choices—whether deciding on investments, relationships, habits or leadership. Understanding how your mind works gives you a competitive edge.
If you’re intrigued by human behaviour, decision science or improving your judgement—this summary invites you into that world in just five minutes.
