Annie Duke

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.
