The obsessive enforcement of ideological conformity within communities that claim to champion "science and reason." It involves purging members, silencing discussions, or ostracizing individuals who engage with ideas labeled "pseudoscientific," even tangentially or critically. This purity spiral values rhetorical and tribal cleanliness over genuine intellectual rigor. It creates echo chambers where the primary activity is not exploring truth, but performing one's allegiance by correctly identifying and shunning the "contaminated" other. Debate is replaced by excommunication.
Example: "The skeptic forum descended into anti-pseudoscience purity. A moderator was doxxed and expelled for the crime of attending a public lecture on the history of alchemy—not to believe it, but to understand its historical context. The ruling clique declared, 'Engagement with the topic is contamination. True skeptics must maintain purity of contact.' Their community became a sterile lab where no actual thinking, only ritualized disdain, was allowed."
