Original：🇺🇸 English

Not Translated

Use when asked to "thinking in bets", "make decisions under uncertainty", "think probabilistically", "avoid resulting", "separate decision quality from outcomes", or "reduce bias in decisions". Helps make explicit bets and evaluate decisions on process, not results. The Thinking in Bets framework (from Annie Duke) applies poker strategy to business and life decisions.

Thinking in Bets

What It Is

Thinking in Bets is a framework for improving decision quality by separating decisions from outcomes. The core insight: a good decision can have a bad outcome, and a bad decision can have a good outcome—luck is always involved.

Most people judge decisions by their outcomes (called "resulting"). This is backwards. You can only control the quality of your decision, not the outcome. Annie Duke, a professional poker player turned decision strategist, built this framework from poker, where you're forced to make decisions with incomplete information under uncertainty—exactly like business.

The key shifts:

Move from "Was I right?" to "Was my thinking process good?"
Move from "What happened?" to "What did I know at the time?"
Move from implicit assumptions to explicit, testable beliefs

When to Use It

Use Thinking in Bets when you need to:

Evaluate past decisions without outcome bias clouding judgment
Make decisions under uncertainty where luck will influence results
Improve team decision-making in meetings and planning
Set up pre-mortems and kill criteria for projects
Shorten feedback loops on decisions with delayed outcomes
Reduce cognitive biases like overconfidence, hindsight bias, and sunk cost
Run better meetings that surface true opinions, not groupthink

When Not to Use It

The decision is trivial with low stakes
You have perfect information (rare)
You're looking for permission to take a risk you've already decided on

Patterns

Detailed examples showing how to apply Thinking in Bets correctly. Each pattern shows a common mistake and the correct approach.

Critical (get these wrong and you've wasted your time)

Pattern	What It Teaches
resulting	Don't judge decisions by outcomes—judge by the process
implicit-vs-explicit	Make intuitions explicit so you can test and improve them
discover-discuss-decide	Separate discovery (async), discussion (meetings), and decisions
premortems-without-kill-criteria	Pre-mortems are useless without committed actions

High Impact

Pattern	What It Teaches
overconfidence	Use ranges, not point estimates—you know less than you think
hindsight-bias	What seems obvious now wasn't obvious then
sunk-cost	Past investment is irrelevant to future decisions
anchoring-in-groups	First opinions contaminate everyone else's judgment
long-feedback-loops	No feedback loop is actually long—find intermediate signals
seeking-alignment	Stop seeking agreement—it's coercive and unrealistic

Medium Impact

Pattern	What It Teaches
confirmation-bias	Seek out information that proves you wrong
mental-time-travel	Ask: "How will I feel about this in 10 years?"
forecasting-ranges	Replace certainty with calibrated probability ranges
nevertheless-leadership	Hear everyone, then decide—"nevertheless" is your friend
