Recognize → Test → Counter → Decide

Audit the decision, not your personality.

This worksheet does not detect a bias or score how rational you are. It helps you record what you believe, test alternatives, use one evidence-reviewed pattern as a lens, and write the next action explicitly.

Recognize

Write the decision before explaining it.

Decision, belief, or forecast under review

Current confidence 0–100%

Stakes

Choose a lens

Pick a reviewed pattern only if it helps test the decision.

Evidence-reviewed pattern

Selecting a pattern does not mean you have that bias. It only changes the countermeasure shown below.

Test

Make the decision falsifiable.

What evidence would meaningfully change your mind?What evidence currently points the other way?What is the strongest competing explanation or alternative hypothesis?What does the outside view or reference class suggest?

Counter

Pre-commit to a failure condition.

What would make continuing with the current plan a mistake?What important information is missing, expensive to obtain, or easy to ignore?How will you apply the countermeasure in this specific case?

Decide

Write the next move and the trigger to review it.

Next decision or action

Review date

Or review trigger

Confidence after the audit 0–100%

Boundary

This is a thinking aid, not a diagnosis.

The tool does not infer hidden motives, declare that a person “has” a cognitive bias, or tell you which decision is correct. Its job is smaller and more useful: preserve the reasoning trail, surface counterevidence, and make the next test explicit.
