Rating rounds with the reasoning behind each rating
Run an expert panel or a pilot study in rounds. Each person sees their earlier answer, changes it only if they want to, and says why.

Rounds that keep history
Every round has its own wording and dates. Earlier answers are never overwritten.
Who moved, and why
Compare the people who answered both rounds, with the reason they gave for changing.
Fair comparison
Round comparisons use only the people who answered both rounds.
Numbers you can cite
Sample size, dates and wording are on every results page.

Questions about this use.
Can participants see their earlier answer?
Yes. When a new round opens, each person sees what they answered last time and can keep or change it.
Is the data kept per version?
Yes. Question versions and answers are append-only, so a change creates a new version and nothing is overwritten.
