Process Matters more than Output for Distinguishing Humans from Machines
Researchers introduce CogCAPTCHA30, a cognitive task battery that distinguishes humans from AI systems by analyzing the process of decision-making rather than just output quality. The study shows process-level features achieve 0.88 AUC in human-machine discrimination even when task performance is matched, revealing that fine-tuning AI on human cognitive processes improves mimicry but struggles with cross-task generalization.
