Annie Duke on How to Make Smart Decisions Under Uncertainty
Treating decisions as bets forces you to focus on accuracy rather than ego.
30-second summary
Former poker champion Annie Duke explains why judging decisions solely by their outcomes is a mistake—a trap known as 'resulting.' Because the future is shaped by both hidden information and luck, high-quality decisions are probabilistic bets rather than guarantees. To improve decision quality, Duke outlines strategies like forming truth-seeking groups, evaluating choices before outcomes are known, and using Ulysses contracts to guard against future emotional bias.
Core concepts
Avoid 'Resulting' by Separating Outcome from Process
People naturally judge the quality of a decision based on whether the result was good or bad, a cognitive bias Duke calls 'resulting.' In a noisy environment controlled by hidden information and luck, a good decision can lead to a bad outcome, and a bad decision can yield a good outcome. Evaluating choices based on decision quality rather than results prevents overreacting to short-term luck.
Pete Carroll's Super Bowl Pass Call
In the final seconds of the 2015 Super Bowl, Seattle Seahawks coach Pete Carroll called a pass play on the one-yard line instead of running the ball. The pass was intercepted, costing Seattle the game, and commentators universally condemned the call as a disaster. However, pass plays from the one-yard line historically resulted in interceptions only 1% to 2% of the time. Had the pass been caught, the decision would have been praised as genius. The extreme public backlash illustrated 'resulting'—confusing a low-probability bad outcome with a flawed decision process.
Ask 'Do You Want to Bet?' to Prompt Probabilistic Thinking
Explicitly framing opinions as bets shifts thinking away from rigid certainty toward probability. Asking 'do you want to bet?' forces a person to consider why they hold a belief, what information they might be missing, and what alternative outcomes could occur. This simple reframe encourages information-gathering and open-mindedness before risking resources.
John Hennegan's Des Moines Bet
When poker player John Hennegan announced at a table that he could easily move to Des Moines for a month, the other players challenged him to a $30,000 bet with strict isolation conditions. Hennegan accepted and moved immediately, but within two days called to negotiate a settlement, eventually paying $15,000 to return to Las Vegas. Hennegan had formed a rigid belief about his adaptability without weighing how much he valued Las Vegas nightlife. The explicit bet forced him to confront the real probabilities and costs of his choice.
Form Truth-Seeking Groups with a Charter for Accuracy
It is extremely difficult to spot one's own cognitive biases, but external observers can identify them easily. Duke recommends creating 'decision groups' or truth-seeking groups that hold members accountable to three core values: a primary commitment to accuracy over being right, mutual accountability, and openness to diverse or dissenting viewpoints.
Use Ulysses Contracts to Guard Against Future Bias
A Ulysses contract is an advance commitment made by a rational present self to restrict the actions of a potentially irrational future self. By anticipating moments of high emotion or cognitive bias, individuals can pre-set rules, deadlines, or barriers that prevent impulsive choices.
5-minute action
Audit a Recent Decision for 'Resulting' Bias
- Select a recent choice you made that led to an undesirable result.
- List only the information and probabilities that were available to you at the exact moment you made the decision, ignoring what happened afterward.
- Determine whether the bad outcome was caused by a flawed choice process or by a low-probability event (luck).
ExampleIf a project missed its deadline due to a sudden, unforeseen vendor outage, review whether your initial timeline assumptions and contingency plans were reasonable given the data you held before the outage occurred.
