How do status cues of AI agents alter human users’ interpretations and evaluations of these agents during human-AI interactions? Drawing upon social status theories and the CASA paradigm, this study explores the influences of status cues in AI-powered healthcare chatbots on AI credibility assessment via perceived AI agency and AI anxiety. The moderation effects of message contingency are also examined. A 2 (status cues: high-status vs. low-status) × 2 (message contingency: high vs. low) between-subjects experiment was conducted online (N = 209). Results revealed that healthcare chatbots with high-status (vs. low-status) cues were perceived as having more AI agency, which was further associated with higher perceived AI credibility. Perceived AI agency and AI anxiety sequentially mediated the effect of social status cues on perceived AI credibility. Results also showed that high (vs. low) message contingency significantly ameliorated users’ AI anxiety for high-status healthcare chatbots. Theoretical and practical implications are discussed.
