A bias derived from the Scientific Slippery Slope, focusing on the perceived inevitability of a severe “reaction” to any tolerance of non‑scientific ideas. The bias holds that if society does not actively oppose even harmless spiritual or alternative practices, a reactionary backlash will install dangerous forms of irrationalism in their place. It treats the public as a pendulum that will swing violently from the first small concession to total unreason unless held in check. Reaction Bias is often used to justify aggressive, confrontational advocacy for scientific orthodoxy.
