In this paper, we argue that boredom can be an important experience that contributes to personal autonomous agency by providing authentic motivation, and that strategies of social media providers to bind users’ attention to their platforms undermine this authenticity. As discussed in social epistemology and media ethics for a while now, such strategies can lead to so-called epistemic or filter bubbles. Our analysis of the relation between boredom and social media use focuses on a similarly impairing effect of social media (...) on users’ autonomy, which we call authenticity bubbles. (shrink)
