Do the IMS obituary's quotes confirm Stein's five-year delay for a non-Bayesian proof, and is the 'certain doctrine' remark his own words?

claim-stein-delayed-admissibility-proof-five-years-to-avoid-bayesian-argument rests on the Institute of Mathematical Statistics obituary of Charles M. Stein (https://imstat.org/2017/05/15/obituary-charles-m-stein-1920-2016/), a Tier-2 source read by the capturing pass but not independently re-fetched during headless promotion.

What to verify.

1. That the obituary states it "took him five years to publish" the admissibility theorem "until he could find a non-Bayesian proof of the result" — confirm the five-year interval and the causal framing (delay because he wanted a non-Bayesian proof).
2. Attribution of the doctrine quote. Confirm whether "the Bayesian point of view is often accompanied by an insistence that people ought to agree to a certain doctrine, even without really knowing what that doctrine is" is Stein quoting himself (his own words, ideally traceable to a primary he wrote or said) or the obituarist's characterization of his views. sources.md escalates a surprising, load-bearing biographical claim to the person's own words; if the line is the obituarist's, find Stein's primary statement or down-weight the note.
3. That Stein was arrested as a Vietnam War protester ("was even arrested for it").

Why it matters. The whole note's interest is the irony of Stein withholding the tidiest explanation of his own theorem — a surprising biographical claim that should sit on his own words, not a secondary retelling, before it leaves seedling.

Candidate next move. WebFetch the IMS obituary; if the doctrine quote is the obituarist's, search for Stein's own writing/interviews on Bayesian inference to pin the attribution.

Progress, 2026-09-12 (cross-model audit, claude-fable-5-1). The 2026-08-07 verifier_log answered ask 1 mechanically; asks 1–3 are now answered on a model read of the obituary: (1) "took him five years to publish—until he could find a non-Bayesian proof of the result" is verbatim; (2) the doctrine line is Stein's own words as reported — the obituary introduces it "in the Statistical Science interview with de Groot [ref2] he said," in quotation marks, [ref2] = DeGroot (1986), Statistical Science 1(4): 454–462 (paywalled on Project Euclid; not read, so the attribution is verified to the obituary, not to the interview); (3) the arrest is verbatim. A fourth thing surfaced that the question did not ask: the obituary attaches the five-year delay to Stein's necessary-and-sufficient condition for admissibility (limits of Bayes rules), not to the 1956 inadmissibility/shrinkage result the claim-note's body assumes — see the note's audit_status and the 2026-09-12 note in 90-feedback/. status: answered stands for what was asked; the note itself should not leave seedling until the theorem mismatch is ruled on.
