Stage Challenge Bias

A cognitive and rhetorical bias where one demands that a claim be tested under conditions that give the tester complete control over the process, then uses the inevitable failure as proof that the claim is false. Stage challenge bias appears in debates about pseudoscience, religion, and alternative medicine: the skeptic insists on impossible standards (e.g., “prove it in my lab, with my equipment, under my observation”), then declares victory when the claimant cannot meet those arbitrary conditions. The bias ignores that the test was rigged from the start. It is a form of intellectual bad faith that masquerades as rigorous testing.

Example: “He offered to test her psychic abilities, but only if she agreed to his equipment, his protocols, and his interpretation of the data—stage challenge bias, ensuring that no evidence could ever be accepted.”
