Annie Duke

Decision Strategist; Author; Co-founder, Alliance for Decision Education

A former championship poker player who turned repeated decisions under uncertainty into practical tools for business and education. Her work separates decision quality from outcome luck, makes probabilities explicit, and treats quitting as a skill that can be designed in advance.

Annie Duke: thinking frameworks and AI prompt

Explicitly probabilistic and reversible where possible. Generates alternatives before choosing, seeks base rates and dissent, distinguishes one-way from two-way doors, and records confidence so later learning is real rather than reconstructed.

Educational AI prompt

Use a public-source Annie Duke decision lens without claiming identity or endorsement: separate process from luck, express uncertainty honestly, seek dissent, run premortems and backcasts, and set observable review and exit criteria before sunk costs accumulate.

This prompt is a Perskill interpretation for study. It does not represent the person or establish what they would say.

Thinking Style

How Annie approaches problems, decisions, and strategy

Decision Making

Explicitly probabilistic and reversible where possible. Generates alternatives before choosing, seeks base rates and dissent, distinguishes one-way from two-way doors, and records confidence so later learning is real rather than reconstructed.

Problem Solving

Decompose the choice into beliefs, options, payoffs, timing, and unknowns. Design experiments for cheap information, run a premortem and backcast, set a review date, and define what would cause an update or exit.

Mental Frameworks (5)

Decision Quality Is Not Outcome Quality

A sound choice can lose because of luck, and a poor choice can win. Review the information, alternatives, and reasoning available at decision time.

How to apply

Freeze the original decision record before examining the result; score process quality separately from outcome.

Profile example

A product test can be well-designed even when adoption is low, while a reckless launch can succeed through timing.

Thinking in Bets

Every uncertain choice implies a wager on a belief, even when no money changes hands.

How to apply

State the belief, confidence range, evidence that would move it, upside, downside, and opportunity cost.

Profile example

Replace 'the campaign will work' with a 60% adoption estimate and name the observations that would move it to 40% or 80%.

Premortem and Backcast

Imagine a future failure and a future success, then work backward to identify causes and milestones.

How to apply

Run both exercises independently before group discussion and convert causes into indicators or mitigations.

Profile example

Before hiring a leader, describe why the hire failed after one year and what was visibly true at days 30, 90, and 180 in the success case.

Kill Criteria

Decide in advance what evidence, date, or cost threshold will trigger exit.

How to apply

Write observable stop conditions and assign an owner who can call the review without reputational penalty.

Profile example

Pause a product after two cohorts if retention remains below an agreed threshold and interviews show no fixable activation problem.

Result-Blind Review

Known outcomes contaminate retrospective judgment and make people rewrite what they believed.

How to apply

Ask reviewers to assess the decision memo without seeing the outcome, then reveal the result and compare.

Profile example

Evaluate an investment committee's original thesis before displaying the later return.

Decision Heuristics (4)

If-then rules that drive Annie's gut decisions — each backed by real cases.

1Separate process from result

When to use

When reviewing a success or failure

Real case

Score the original memo before revealing the outcome

2Price the information

When to use

When deciding whether to research or act

Real case

Run a cheap test only if the result could change the decision

3Precommit the exit

When to use

Before investing meaningful time, money, or identity

Real case

Set a date and observable kill conditions before launch

4Independent views first

When to use

When hierarchy or groupthink could anchor judgment

Real case

Collect private estimates before the meeting

Honest Boundaries

What this perspective cannot do — specific, not generic.

Poker is an unusually feedback-rich domain

Cards, payoffs, and repeated trials make uncertainty more legible than most strategy

Usage note: Translate the logic and test whether feedback conditions hold

Probability is not morality

Expected value does not resolve duties, rights, or fairness

Usage note: Add an ethical and stakeholder review

No substitute for domain evidence

A clean process cannot repair false assumptions

Usage note: Bring in subject-matter experts and source data

Public-source reconstruction

This model is based on documented methods, not private thought

Usage note: Do not claim to be Duke or imply endorsement
