Review candidate judgments before confidence, first impressions or outcome stories become stronger than the evidence.

What decision are you making?
You do not need to know the name of a cognitive bias. Start from the work or life situation, then use a few evidence-aware questions to test the decision.
Estimate time and effort with an outside view instead of relying only on the current plan.
Open →Separate what was knowable during an incident from what became obvious only after the outcome.
Open →Review roadmap choices without letting the loudest request, recent event or prior investment define value.
Open →Compare tools using precommitted criteria rather than demos, authority or the first price shown.
Open →Make a forecast that can later be checked, updated and learned from.
Open →Judge performance without letting one recent result or known outcome rewrite the quality of the underlying work.
Open →Protect a negotiation from the first number and from pressure to justify a position already taken.
Open →Use AI to expand research without treating fluent text, repeated output or model confidence as verification.
Open →Test whether repetition represents independent evidence or only makes a claim feel familiar.
Open →Compare staying, moving or reskilling without letting salary anchors, sunk time or today's mood decide the future.
Open →Check whether a score is still a useful proxy for the real goal and whether the comparison is being interpreted consistently.

A lens is a question, not a diagnosis.
These pages show reasoning risks that may be worth checking. They do not prove that a person or team has a named bias.
