A sophisticated rhetorical tactic where one demands proof not to find truth, but to exhaust opponents and avoid engagement. Proof Sophism begins with reasonable requests—"source?" "evidence?"—but then relentlessly moves the goalposts. When a source is provided, it's dismissed as biased, outdated, or insufficient. When stronger evidence appears, the demand shifts to impossible standards: double-blind RCTs for historical claims, video evidence for events before cameras, personal testimony for statistical phenomena. The goal is not evidence but exhaustion—making the opponent chase an ever-receding horizon of proof until they give up. Proof Sophism weaponizes the very idea of proof, using the appearance of rigor to destroy the possibility of dialogue.
"She provided a study. 'That journal is biased,' he said. She found a meta-analysis. 'Too old.' She found a recent review. 'Not specific enough.' She found exactly what he asked for—and he demanded video evidence. Of a historical event. Proof Sophism: proof as infinite regress, evidence as exhaustion. He never wanted to know; he wanted her to quit."
