# UX evidence synthesis

## Procedure

1. Convert the decision into claims that could be supported or contradicted.
2. Gather direct product evidence, primary research, standards, expert inspection, and anecdotes separately.
3. For each source record population, method, setting, date, outcome, limitations, and relevance.
4. Grade each claim E1 through E5 using the bundle evidence ladder.
5. Identify convergence, contradiction, segmentation, measurement gaps, and alternative explanations.
6. State what decision the evidence supports now and the smallest study needed for unresolved claims.

Never calculate prevalence from social posts or combine incompatible measures into a synthetic score.
