Do social media users read, comment, and share false news more than real news? Does it matter if the story is written by a bot and whether it is endorsed by many others? We conducted a selective-exposure experiment ( N = 171) to answer these questions. Results showed that real articles were more likely to receive “likes” whereas false articles were more likely to receive comments. Users commented more on a bot-written article when it received fewer likes. We explored the psychological mechanisms underlying these findings in Study 2 ( N = 284). Data indicate that users’ engagement with online news is largely driven by emotions elicited by news content and heuristics triggered by interface cues, such that curiosity increases consumption of real news, whereas uneasiness triggered by a high number of “likes” encourages comments on fake news.
In this study, the constructive communication process of anti-vaccination advocates is explored to provide insight into the challenges of communicating with an engaged, educated public that is distrustful of mainstream medical and governmental organizations. Using the circuit of culture as a theoretical and methodological model, this article examines how anti-vaccination advocates use social media to construct and reinforce a belief system that counters dominate understandings of health. Findings show that, through online communication, anti-vaccination advocates create shared cultural constructs embracing the identity of health information crusader, critic, and expert. This community consumes, produces, and distributes information that reframes mainstream health information and reinforces shared values. The purposes of this study are to better understand the culture of anti-vaccination advocates, identify communication barriers, and offer practical implications for health care professionals.
