Dawid & Skene (1979) reportedly proposed weighting each observer's vote by past performance — RA-RAG's mechanism, 46 years earlier — but the exact wording is not yet quote-verified

Beyond the confusion-matrix/EM estimation method itself, Dawid & Skene (1979) reportedly proposes, in its own introduction, a reliability-weighted consensus scheme: each observer's vote weighted by "his previous performance" at the rating task. If accurate, this is functionally the same idea RA-RAG implements in 2025 — weight a source's contribution by a separately-estimated measure of that source's own reliability — proposed 46 years earlier, inside a paper about reconciling disagreeing anaesthetists.

This claim is flagged, not confirmed. The hop-bee read the PDF directly at capture time — this is not a search-summary or fetch-and-summarize artifact — but the extracted text's OCR mangles the relevant sentence's spacing badly enough that no clean, defensible verbatim phrase could be captured. Per the vault's sourcing floor, a specific technical-mechanism claim requires a Tier 1–2 source with the exact quoted phrase; a garbled OCR extraction does not clear that bar even though the underlying document does. The claim is recorded as a lead, kept at seedling, and routed to question-verify-dawid-skene-1979-reliability-weighted-voting-quote rather than promoted to evergreen on a reconstructed paraphrase.

If confirmed, this is the specific sentence that upgrades the citation lineage from "Dawid & Skene originated the estimation method RA-RAG's weighting rests on" to "Dawid & Skene originated the weighting idea itself."
