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.
