A fallacy where someone argues that because a claim cannot be proven false, it must therefore be false. This inverts the proper use of falsifiability, which is a criterion for scientific status, not a test for falsehood. The fallacy typically appears in debates about religion, spirituality, or metaphysics: "You can't prove God doesn't exist, so God must not exist." But the same logic would prove anything unfalsifiable false—a absurd consequence. The fallacy confuses burden of proof (claims need evidence) with falsifiability as a truth test. Unfalsifiable claims aren't automatically false—they're just not empirically testable. Their truth or falsehood must be evaluated by other standards.
