Bio
Annie Duke's intellectual project is the systematic separation of decision quality from outcome quality. Drawing on 20 years of professional poker, where the best possible decision frequently produces a losing hand, Duke demonstrates that most people commit "resulting," the error of judging decisions by their outcomes rather than by the process used to make them. A good decision made with sound reasoning can still produce a bad outcome due to luck, incomplete information, or factors outside your control. Conversely, a terrible decision can produce a great outcome.
Operating themes
- Operating thesis: The quality of a decision and the quality of its outcome are fundamentally different things; learning to separate the two is the single most important skill for anyone who operates under uncertainty.
- Decision Quality Framework
- Cognitive Bias Management
Cards
- Pre-mortems only work if you commit kill criteria before starting — Pre-mortems become decision gates only with explicit kill thresholds [Tier A]
- Force intuitions into explicit predictions so you can find out where you are wrong — Force intuitions into falsifiable predictions to learn from them [Tier B]
- There is no such thing as a long feedback loop — find a correlated short signal — Replace the long signal with a correlated short one [Tier B]
