Appeal to the stone (argumentum ad lapidem)

Biological Parallel

Crows encountering a novel food source often ignore it entirely—neophobia protects against poisoning, and the cost of investigation (wasted energy, potential toxicity) can exceed the benefit of a new resource. Dismissing claims as 'obviously false' without examination exploits this same metabolic calculus: our brains evolved to conserve cognitive energy by rejecting improbable claims immediately. In ancestral environments where most novel claims were indeed false or irrelevant, reflexive dismissal was adaptive. Modern information complexity hasn't updated this Bayesian prior.
