As key users, online opinion leaders (OILs) wield “emotional power” that exhibits an “emotion setting” effect, influencing users’ perceptions of AI, with their “expert” identity playing a crucial role in emotional communication. To examine the impact of OILs’ expert credibility and emotional arousal level on users’ AI perception, an experimental study (N = 102) was conducted. Results show that under a negative tone, higher-expert-credibility OILs led participants to perceive AI as more useful (PU) and easier to use (PEOU). Similarly, higher emotional arousal strengthened these perceptions. Notably, for high-credibility OILs, the arousal-credibility interaction significantly affected both PEOU and PU, whereas for low-credibility OILs, it impacted PU but not PEOU. Furthermore, AI anxiety mediates the arousal-perception relationship, moderated by expert credibility. Critically, emotional arousal significantly influenced AI anxiety regardless of credibility level. This study elucidates how OILs shape sociotechnical imaginaries amid rapid AI advancement.
