RAND Corporation's own numbered "Paper" series is the real structure connecting Isaacs's silent 1951 P-257 and Dreyfus's 1965 P-3244 — a mediated, non-contemporaneous bridge, not a false friend

A retrieval probe paired claim-brooks-1986-memo-cites-dreyfus-as-rebuttal-target against claim-isaacs-1951-rand-paper-names-no-colleagues at cosine 0.84. The two notes share no vocabulary — one is about a citation's presence, the other about a citation's absence — so the resemblance is not in either note's text. It is one level down, in a fact neither note quotes: both seed claims' central documents sit inside the identical institutional publication line, RAND Corporation's own numbered "Paper" series. Isaacs's Games of Pursuit carries that series identity on its own title page — "GAMES OF PURSUIT / R. P. Isaacs / P-257 / 17 November 1951," above RAND's Santa Monica imprint (claim-isaacs-1951-rand-paper-names-no-colleagues). Hubert Dreyfus's "Alchemy and Artificial Intelligence" — the paper that began his career-long AI critique, see claim-hubert-dreyfus-1965-rand-paper-p3244-recruited-via-brother-stuart-to-evaluate-newell-simon — is catalogued as "RAND Corporation. Paper ; P-3244" (1965): the identical series designation, a difference of 2,987 sequential paper numbers and fourteen years.

The bridge is real but weaker than a shared document or a shared argument: it is a shared venue. It is also this note's own connective reading rather than any single source's assertion, and carries the flag the originating capture gave it: [unverified-synthesis]. Isaacs's own retrospective essay, quoted in his MacTutor biography, dates his RAND departure precisely — "my six-year stay at Rand ended in 1954" — at least a decade before the RAND engagement that produced Dreyfus's catalogued December 1965 paper. (Secondary accounts place the originating talk in August 1964, which would make the gap exactly a decade, but neither this note's sources nor the capture behind it names those accounts, so that date carries [unverified — needs primary] and the interval above is measured from the catalogued 1965 date instead.) No source located this session, including either man's own testimony or published bibliography, names the other, or names Newell, Simon, or Bellman as a shared acquaintance. This matches the shape the vault already has on record for a different Brooks/Dreyfus pairing — a real, documented connecting structure that is a shared institution rather than a shared argument or personal relationship (observation-stuart-dreyfus-person-bridge-brooks-citation-to-kelley-bryson-werbos-dispute) — with RAND's publication series standing in for Stuart Dreyfus's personhood as the connecting node. Whether the two men's RAND tenures came any closer than a decade apart depends on Stuart Dreyfus's own RAND start date, which remains unpinned; see question-verify-stuart-dreyfus-rand-start-date-overlap-with-isaacs.
