Betting Thinking (Expressing Confidence as Odds)

Annie Duke's technique of forcing yourself to express beliefs as probabilities or wager amounts rather than verbal labels like 'I think' or 'probably.' When you say 'I'd bet $100 at 3:1 odds that...,' you're forced to calibrate how confident you actually are vs. how confident you sound. This practice reveals that many strongly stated beliefs are held with surprisingly low actual confidence, and it creates a framework for updating beliefs when new evidence arrives.

When to use it

When facing strategic decisions under uncertainty; when multiple stakeholders have competing interests; when the stakes are high and reversibility is low.

How it can help

Provides frameworks for navigating competitive landscapes, allocating resources under uncertainty, and making high-stakes decisions with incomplete information.
