Thinking in Bets
A probabilistic approach to decisions that separates the quality of a choice from the luck of one outcome.
Why it matters
Good decisions can lose and bad decisions can win; judging only by results teaches the wrong lesson.

Core ideas
What is worth remembering after you close the page
01
Outcome is not decision quality
Luck can hide a poor process or punish a sound one.
02
Use confidence levels
Probabilistic language makes uncertainty explicit and easier to update.
03
Create truth-seeking groups
Good feedback environments reward accuracy more than defending a previous position.
03
Turn it into action
Three things to test today
- 1
Assign a confidence percentage to one important belief.
- 2
Write what evidence would move that number.
- 3
Review a past decision by process before looking at the outcome.
