How the Anthropomorphism of an Artificial Intelligence Agent Affects the Correction of Misinformation: A Focus on Authenticity and Behavioral-Response System Level

AI agents are increasingly leveraged to counter misinformation. This study probes their impact on correction, focusing on user interaction authenticity. Examining anthropomorphism and behavioral response, it seeks to discern how perceived authenticity shapes AI agents' persuasive impact in misinformation correction. In a 2x2 experiment with 320 participants correcting misinformation about the HPV vaccine, high anthropomorphism induces greater authenticity in source, message, and interaction compared to low anthropomorphism. Additionally, perceived interaction authenticity mediates the relationship between anthropomorphism and attitudinal change, moderated by the behavioral response system level. These findings provide vital evidence underlining the importance of anthropomorphism and behavioral response in fostering authentic interactions, with practical implications.
