What a reference does—and does not—prove

A citation is useful only when you can see how it supports the claim beside it.

Match source to claim

Detector documentation can describe a model’s outputs. It does not validate an aesthetic recommendation. A preference-based suggestion should be presented as a preference-based suggestion.

Look for limitations

Population, study design, image conditions, and the actual measured outcome can all limit applicability. Correlation does not show that purchasing an assessment causes a better outcome.

Ask for a clearer explanation

Your report should connect the observation, action, reasoning, reference, and uncertainty. If that chain is unclear, ask for a correction before acting.
