Thinking in Bets

A former World Series of Poker champion turned decision strategist shows how to make better decisions when you can never have complete information. Annie Duke brings together insights from cognitive psychology, her academic background, and years at the poker table to offer a practical framework for thinking under uncertainty.

Why Start Here

Strategy is ultimately about making decisions, and most of us are terrible at evaluating our own decisions. We confuse good outcomes with good decision-making, blame bad luck when our reasoning was flawed, and take credit for skill when we were simply fortunate. Duke calls this “resulting,” and it is the enemy of strategic improvement.

Her core insight is that life is more like poker than chess. In chess, all the information is visible. In poker, and in business, you make decisions with incomplete information, and the outcome always involves some element of luck. Once you accept this, you stop trying to be right all the time and start trying to be less wrong over time. You learn to think in probabilities rather than certainties, to separate the quality of your decisions from the quality of your outcomes.

The book gives you concrete tools: how to form a decision group that challenges your thinking, how to conduct a “premortem” before committing to a plan, and how to update your beliefs as new information arrives. These tools apply directly to strategic thinking in any context.

What to Expect
