Thinking in Bets: Making Smarter Decisions When You Don’t Have All the Facts is Annie Duke’s first book, drawing on her years as a professional poker player to reframe how we judge decisions. Its central argument is that life resembles poker more than chess: outcomes are a mix of skill and luck under hidden information, so a good decision can produce a bad result and vice versa.

The book attacks resulting — the habit of judging a decision’s quality by how it turned out — and proposes that we treat beliefs and choices as bets: probabilistic commitments held with calibrated confidence rather than binary certainty. Asking ‘wanna bet?’ exposes how sure we really are. Duke argues for separating decision quality from outcome quality, seeking truth-tracking groups that reward accuracy over agreement, and using techniques such as mental time travel and pre-commitment to counter in-the-moment bias.

The work is heavily indebted to the behavioural-economics tradition, especially Daniel Kahneman, with whom Duke later became close.

In the wiki

Annie Duke draws on the book throughout Annie Duke on Better Decisions, Kill Criteria, and When to Quit. The episode’s master move — making the implicit explicit so intuition can be checked against outcomes — is the operational core of the book, applied to meetings via the Nominal Group Technique and to investing via First Round Capital’s structured rubrics. Resulting surfaces in her parenting examples (feeling like a great parent off one well-behaved child, then learning it was temperament).
