Annie Duke on Thinking in Bets - And Why Winners Can Be Wrong

Legendary poker champion, decision scientist, and author of "Thinking in Bets," Annie Duke deconstructs the mechanics of decision-making under uncertainty, shifting the focus from high-variance outcomes to the rigor of positive expectancy and robust process. Leveraging her background in professional poker and cognitive psychology, Duke explores how loss aversion and resulting—the cognitive trap of equating outcome quality with decision quality—can degrade a trader's edge and lead to suboptimal portfolio construction. The conversation moves beyond theory into the practical application of base rates, reference classes, and mental time travel to combat temporal discounting, providing a masterclass for quants, PMs, and analysts on how to refine their probabilistic worldview and neutralize the noise of short-term volatility.00:00 Intro01:12 Defining bets as resource allocation under uncertainty04:52 Positive expectancy vs. outcome-based evaluation06:11 Resulting: Why outcomes are not proxies for decision quality15:19 Calculating expected value in high-variance career paths18:55 Moving from implicit intuition to explicit decision modeling24:27 Using base rates and reference classes for startups30:26 Psychological traits of elite risk takers and traders31:33 How prospect theory and loss aversion distort risk45:12 Deconstructing gut feel and the role of intuition49:36 Evaluating optionality and impact in fast-moving environments57:13 Mental time travel: Tools for managing temporal discounting01:01:31 Quantifying the intersection of luck and hard work01:04:43 Internalizing a probabilistic worldview for long-term edge
