October 24, 2026 · Annie Duke, Thinking in Bets: Making Smarter Decisions When You Don't Have All the Facts · Nonfiction · About 4 minutes
Twenty-six seconds remain in Super Bowl XLIX. Seattle trails New England by four points and has the ball at the one-yard line. Coach Pete Carroll calls a pass rather than handing it to his star running back. The pass is intercepted; Seattle loses. The play becomes, for many observers, proof that Carroll made a terrible decision. Annie Duke begins Thinking in Bets with this moment because it is so tempting to work backward from the final score to the quality of the choice.[1]
Now set that play beside another: three Super Bowls later, Philadelphia coach Doug Pederson goes for it on fourth down near the goal line and calls the trick play known as the Philly Special. Quarterback Nick Foles catches a touchdown pass. Pederson is celebrated for boldness. Duke argues that the two receptions—one by the defense, one by the intended receiver—colored how people judged the coaches' thinking. She calls that habit resulting: using the outcome as the verdict on the decision.[2]
An outcome is evidence, but it is not a full account of the decision that produced it. The useful question is not, “Did it work?” alone. It is: Given what was knowable at the time, what alternatives were available, what did each risk, and why was this one chosen? Duke's book asks us to make room for both luck and missing information rather than granting the eventual winner automatic wisdom.[1]
This is not a license to excuse every failed choice as bad luck. Perhaps a warning was ignored or the downside was too costly even if success was likely. Nor does a lucky success cleanse a reckless process. Results deserve inspection, but a single result rarely tells you enough to grade the process. Repeated outcomes can reveal patterns; one dramatic outcome may mostly reveal how dramatic it felt.
Duke's football comparison also needs a limit. A coach has access to information, constraints, and people that a spectator does not. We need not declare Carroll's specific call correct to see the broader error in declaring it wrong solely because the pass was intercepted. The book is more useful as a discipline for inquiry than as a machine for proving any controversial choice was secretly brilliant.[1][2]
Imagine spending two weekends building a prototype for a possible customer. Nobody signs up. It is easy to say, “I knew this was a bad idea.” But suppose five people had described the problem, you had set a strict time budget, and your aim was to test whether they would actually try a solution. The experiment may have worked: it cheaply exposed a mismatch between words and behavior. You can still ask whether the audience and test were well designed. This example is mine, not Duke's.
Reverse the story. Suppose three people sign up. That is encouraging, but it does not prove you identified a large market or chose the best possible use of those weekends. Maybe they are unusually close friends; maybe their enthusiasm disappears when money is involved. Celebration and scrutiny can coexist. Record what happened, then compare it with the expectation you wrote down before seeing the result.
The same practice applies elsewhere. A declined dinner invitation does not prove that reaching out was foolish. An impulsive purchase that rises in value does not prove that the risk was wise. A reversible test warrants less analysis than a choice that could damage your finances or another person's trust. The point is not to turn every moment into a spreadsheet. It is to prevent hindsight from rewriting your reasons.
A two-minute exercise: Pick one decision you expect to make this week. Before acting, write three lines: “I choose ___ because ___.” “The most plausible way this goes wrong is ___.” “Even if the result is good, I should reconsider my method if ___.” Revisit those lines afterward. Ask what you learned about your reasoning, not just whether you won.
The intercepted pass was real; so was the decision before it. Keeping both in view makes it possible to learn without treating every loss as a confession or every win as a certificate of wisdom.[1][2]
