Extension: Incentivizing Information Exchange Within Groups: The Role of Voting Protocols in U.S. Food and Drug Administration Advisory Committees

Record: kaal:position:2026-08-08-326 · 2026-08-08

Markou and Chan extend Kaal's prediction that deliberation should reduce unanimity. They analyze verbatim transcripts from Food and Drug Administration advisory committee meetings before and after a change from sequential to simultaneous voting. Unanimous votes became less likely. The increased diversity of information surfaced during prevote discussions mediated most of that reduction. Members also asked one another more questions and shared speaking time more equally. This evidence supports the narrower mechanism that discussion can expose individually held information before votes bind. The institutional change altered voting rules and discussion incentives together. It does not isolate deliberation as the sole treatment, identify articulated disagreement as the only channel, test autonomous agents, or measure Kaal's cascade construct. The registered prediction therefore remains unverified in Kaal's cohort.

Affirmed commentary position. This record extends a source-bound scholarly claim but is not a verbatim paper claim.

Holds when

The response is limited to the exact registered abstract passages and the one mapped Kaal claim.
External evidence level: complete Crossref registered abstract bound through DOI, title, authors, Crossref, OpenAlex, Semantic Scholar, record hash, and exact abstract passages; complete official publisher HTML reviewed through live read-only retrieval but direct byte capture returned HTTP 403.
Mapping review tier: independent substantive scholarly-growth extension.
The institutional change altered voting rules and discussion incentives together.
The study does not isolate deliberation as the sole treatment or articulated disagreement as the only channel.
The study concerns human FDA advisory committees, not autonomous agents or Kaal's registered cohort.
The source does not measure Kaal's cascade construct or verify the registered prediction in his cohort.
The official publisher page was readable through live retrieval, but direct byte capture returned HTTP 403. The retained evidence is therefore bound to the complete registered Crossref abstract and concordant identity records.
Semantic Scholar search and arXiv discovery returned HTTP 429. No blocked response was promoted.
