Description
Katy Chalmers and co-authors study how feedback shapes expert surveys in this 2026 methods paper. Core data sets, the agreed minimum every registry should collect, are built by Delphi surveys, where stakeholders score items over rounds and re-score after seeing group feedback.
Inside a real core set project, round-two participants were split by chance into standard feedback or an enhanced version adding the top five items from round one. Both groups prioritised more items in round two, and agreement between them rose. The extra top-five summary barely changed what got prioritised, though. The authors say feedback design still needs work, including talking with stakeholders about how they read it.
