Thinking in Bets
by Annie Duke
Every decision is a bet on an uncertain future, so judge choices by the quality of your reasoning at the time, not by how they happened to turn out.
What it teaches
Drawing on her years as a professional poker player, Duke reframes decision-making as wagering under incomplete information. Her central target is 'resulting': the habit of grading a decision by its outcome, which conflates skill with luck and teaches the wrong lessons. A sound call can lose and a reckless one can win, because chance intervenes between decision and result. Her remedy is to think probabilistically, replacing false certainty with calibrated confidence, and to reason in terms of expected value across the range of possible futures. She adds practical tools: cultivating truth-telling peer groups, mentally time-traveling to pre-mortem failures before they happen, and separating the bettor from the ego. The tone is brisk and conversational. It rewards managers, investors, and anyone who wants to learn faster by separating the decision from the dice.
