Misinformation remains pervasive in digital platforms, shaping how individuals receive news online. Prior work suggests that credibility perceptions of misinformation can differ based on the modality of the misinformation message. Informed by the MAIN model, this quantitative study conducted two separate 2 (Modality: video or text) x 2 (Social endorsement cues: high vs. low) between-subject experiments to assess the influence of message modality and social endorsement cues on misinformation credibility judgments. The experiments reviewed two different topics of misinformation: artificial intelligence technology malfunction (N = 296) and a cure for cancer (N = 306). Results for Study 1 on artificial intelligent technology malfunction misinformation indicated that participants who viewed the video modality judged a higher perception of source expertise and message credibility. The results of Study 2 suggested that the text presentation of health misinformation prompted higher message elaboration relative to the video conditions. Findings suggest that modality does influence how people judge misinformation messages depending on the subject matter. In addition, source credibility influences how people judge message credibility. The paper concludes with a discussion of theoretical implications and practical applications.
