Thinking in Bets
Annie Duke · 2018
PsychologyMaking Smarter Decisions When You Don't Have All the Facts
Former World Series of Poker champion Annie Duke shows that the quality of our lives is the sum of decision quality plus luck. By thinking in bets — explicitly acknowledging uncertainty and assigning probabilities — we make better decisions, learn faster from outcomes, and avoid the traps of hindsight bias and resulting.
Context & Background
Duke bridges the worlds of poker and cognitive science to show that most decisions aren't like chess (where the right move exists) but like poker (where you're making the best bet with incomplete information). The key insight: you can make a good decision and still get a bad outcome, and vice versa. Separating decision quality from outcome quality is essential for learning.
Resulting — the tendency to judge decision quality by outcomes rather than process. Thinking in bets — reframing decisions as bets forces us to consider probabilities, acknowledge uncertainty, and be more open-minded. Decision groups — surrounding yourself with people who challenge your thinking rather than confirm it. Duke shows how these practices compound over time to produce dramatically better results.
The book was endorsed by leaders across industries and adopted by decision-making training programs. Its framework for separating luck from skill in evaluating outcomes has influenced how organizations conduct post-mortems and strategic reviews.
