The Cowpox of Doubt

A named-concept epistemics classic. Scott argues that harping on easy targets (creationism, homeopathy, moon-hoaxers) is counterproductive: it 'Others' irrationality (training people to think all false beliefs are obvious and that they personally are immune) when rationality should be about 'Self-ing' it. Worse, via the inoculation effect (weak arguments build immunity to strong ones -- the cowpox/smallpox metaphor), constantly debunking dumb beliefs 'vaccinates people against doubt' -- against reading the research themselves, against seeing truth on both sides, against the rare crisis-of-faith skill needed to escape the wrong ideology one was born into. The homeopathy mock-dialogue (some studies, even a Lancet meta-analysis, survive the lazy objections) shows how sloppy debunking breeds sloppiness everywhere.

Quality 80 · Excellent. A genuine SSC classic -- original, important, counterintuitive, and economical, with a memorable coinage ('cowpox of doubt') that has real staying power. The inoculation-against-real-doubt insight is deep and frequently cited. Sits squarely with the other named-concept Excellent essays (Rule Thinkers 80, Preschool-MMTYWTK 80); scored on merit, not popularity.

Claude’s paradigm shift 68 · Notable shift. Naming and dramatizing the inoculation-against-doubt dynamic (and the Othering-vs-Selfing frame) was a genuinely fresh, memorable contribution at the time. High Notable.

Real-world impact 3 · Moderate. 'The cowpox of doubt' became genuinely adopted vocabulary within the rationalist subculture, recurring as a reference; influential within a niche, no material change. Moderate.
