Abstract: Drawing on theories of social media engagement, privacy calculus, and dual information processing, this study examines the relationship between users’ awareness of algorithmic influence on social media content and their behavioral engagement on these platforms. Utilizing a survey of U.S. adult social media users (N = 990), we investigate how self-reported internet literacy and awareness of algorithmically curated media content are associated with social media self-disclosure, as well as passive and active behavioral engagement. Structural equation modeling analysis reveals a positive association between internet literacy and algorithmic media content awareness. Furthermore, both algorithmic media content awareness and self-disclosure significantly predict passive engagement, while self-disclosure and passive engagement, in turn, positively influence active engagement.
