Thinking in Bets

Summary

A professional poker player’s case for separating decision quality from outcome quality — good decisions can lose, bad decisions can win, and conflating the two is why most people never actually improve.

Key ideas

• “Resulting” — judging a decision by its outcome instead of the information available when it was made — is the single biggest bias standing between people and better decisions.
• Think in probabilities, not certainties. “I’m 70% sure” is a more honest and more useful statement than “I’m sure.”
• Build a “truth-seeking pod” — people who will disagree with you honestly, before the decision, not after it fails.

Favorite quote

“Wanna bet?” is a demand for intellectual honesty.

Personal reflection

I’ve started literally asking myself “what odds would I put on this?” before big calls. It’s uncomfortable and it’s exactly the discomfort that’s useful — vague confidence hides bad reasoning.

Practical application

Added a “confidence %” field to my own decision log template, next to the decision and the reasoning, so I can check calibration in hindsight without resulting on myself.
