What is the primary-source wording and framing of McGuire's 1961 origin of inoculation theory ("a vaccine for brainwash")?

The capture 10-inbox/raw/2026-07-11-hop-ai-debunks-conspiracy-dual-use anchors an 80-year prevention→cure→dual-use arc on William McGuire's 1961 coinage of inoculation theory — the "vaccine for brainwash" metaphor, said to react to Korean-War POWs who defected. That framing is currently sourced only at Tier 4–5 (Wikipedia and tertiary explainers). Historical claims are Tier 3–4-acceptable when uncontested, but this one is both surprising and load-bearing to the arc, which escalates the sourcing floor to Tier 1–2 (per 00-meta/specs/sources.md). It was therefore not minted as a claim-note during the 2026-07-11 promotion — it was routed here.

Why it matters

If the arc is ever drafted, McGuire's own words are the opening beat: does he actually use the vaccine/brainwash framing, and is the Korean-War-POW motivation his or a later retrofit? A colorful origin quote that turns out to be a secondary embellishment would undercut the through-line.

What would answer it

• Locate McGuire's primary 1961 publication(s) on resistance to persuasion — most likely McGuire & Papageorgis (1961), Journal of Abnormal and Social Psychology, "The relative efficacy of various types of prior belief-defense in producing immunity against persuasion," and/or McGuire's 1961 "Resistance to persuasion conferred by active and passive prior refutation."
• Confirm (or refute) that the biological-inoculation metaphor is McGuire's own language in the primary text, with an exact quoted phrase.
• Establish whether the Korean-War-POW / "brainwashing" motivation appears in the primary source or is a later narrative overlay.
