Decision guide
Start with the decision, not the label
A bias name is useful only when it helps you test an explanation. Choose the situation closest to yours, compare plausible patterns, and look for evidence that could change your mind.
Evidence feels one-sided

A forecast feels unusually certain
What base rate, outside view, or failure path is absent from the estimate?
Use the reflection engine carefully
Treat its first result as a hypothesis. Review the competing explanations, check the match strength, and refine the description when key context is missing.
