The winner’s curse describes a paradox that shows up everywhere in modern life. The moment we win an auction, land the deal, or beat the competition is often the moment we unknowingly overpaid, overcommitted, or misunderstood the true value of what we gained.
In this episode of Passion Struck, Alex Imas joins John R. Miles to unpack why winning so often leads to regret, how behavioral economics explains this pattern, and what it reveals about the way humans make decisions under uncertainty. Drawing on decades of research and real-world examples, this conversation explores how our mental shortcuts, overconfidence, and distorted perceptions quietly shape outcomes in markets, careers, and everyday choices.
The Curse Explained
This phenomenon occurs when the person who “wins” is actually the one who made the most optimistic error. Because everyone is working with imperfect information, the highest bid or strongest conviction often reflects the biggest overestimation rather than superior insight.
Originally observed in competitive auctions and natural resource markets, the winner’s curse now appears across investing, hiring, negotiations, and even personal life decisions. Winning feels good in the moment, but it can signal that we misunderstood the situation more than anyone else.
This episode explains why success itself can be a warning sign.
Behavioral Economics and Why Rational Models Fail
Traditional economics assumes people evaluate choices calmly and logically. Behavioral economics tells a different story.
Humans rely on shortcuts when facing complexity. We simplify uncertainty, anchor on incomplete information, and confuse confidence with accuracy. Behavioral economics shows that these patterns persist even among experts, professionals, and decision makers with experience. This is not a failure of intelligence. It is a predictable outcome of how the human mind processes uncertainty.

Why This Conversation Matters Today
Alex’s work helps explain why smart people make decisions they later regret. It reveals that confidence, speed, and victory are not reliable indicators of good judgment.
Understanding this concept changes how we interpret success. It encourages better skepticism of easy wins, deeper evaluation of tradeoffs, and more humility in uncertain environments.
In a world shaped by competition, algorithms, and rapid feedback, learning how and why this anomaly operates is essential for making clearer decisions with lasting consequences.
The Winner’s Curse Then and Now
This conversation also draws from The Winner’s Curse: Behavioral Economics Anomalies, Then and Now, co-authored with Richard Thaler.
The book revisits foundational insights in behavioral economics and shows how they continue to shape modern markets, technology-driven decision making, and digital environments where coordination and speed magnify human bias.
The core lesson remains unchanged. The original findings not only hold up, but they also appear almost everywhere.
Risk changes behavior in ways we rarely anticipate.
People plan to cut losses and stay disciplined, yet when outcomes shift, emotions take over. Gains trigger premature exits while losses encourage doubling down. This gap between intention and action explains why portfolios drift, strategies collapse, and regret sets in after the fact.
This anomaly thrives in environments where uncertainty, competition, and emotion collide.
Mental Representation and Decision Making
Mental representation refers to how we frame and imagine the choices in front of us.
When people make decisions, they do not evaluate everything that matters. They focus on what is most vivid or easiest to picture and leave out friction, tradeoffs, and long-term consequences. If something is missing from the mental picture, it cannot influence the decision.
This is why people misjudge happiness, underestimate costs, and make confident predictions that later feel confusing or disappointing. The problem is not the choice itself. It is what never made it into the representation.
Guest Bio – Alex Imas
Alex Imas is a professor of Behavioral Science, Economics, and Applied AI at the University of Chicago Booth School of Business. His research explores how people make decisions under risk and uncertainty, why smart individuals make predictable mistakes, and how technology and AI amplify human biases.
He is the co-author of The Winner’s Curse: Behavioral Economics Anomalies, Then and Now with Nobel Prize winner Richard Thaler, and his work has been recognized with major honors, including the Alfred P. Sloan Research Fellowship. Alex’s insights bridge rigorous behavioral science with real-world decisions in markets, technology, and everyday life.
