The main finding of this report is that social science research reveals that social media platforms can be—and often are—exploited to facilitate political intimidation and violence. Certain features of social media platforms make them susceptible to such exploitation, and some of these features should be changed to reduce the danger. “ The main finding of this report is that social science research reveals that social media platforms can be—and often are— exploited to facilitate political intimidation and violence. ” Based on a review of more than 400 studies published by peer-reviewed journals and think tanks, the report provides a platform-by-platform survey focusing on the particular features of each site that make it susceptible to exploitation by extremists promoting intimidation and violence and/or seeking recruits for their various causes. The report emphasizes that neither subjective observation nor social science research indicates that social media platforms are the sole or even primary cause of political intimidation and violence. Other media and irresponsible political leaders play crucial roles. However, the use of social media can enable or facilitate violence in a fashion that deserves attention and mitigation. Most of this problem—extremism and occasional use of force for political ends—occurs on the political right. But the left is not immune to these pathologies. The platforms discussed in the following pages range from some of the best known, like Facebook and YouTube, to the more recently ascendant TikTok to those on the right-wing fringe, such as Gab, Parler, and 4chan. Among the features, we examine are: • Facebook’s Groups, which helped the sometimes-violent QAnon to grow into a full-blown movement devoted to the delusion that former President Donald Trump has secretly battled “deep state” bureaucrats and Satanic pedophiles.1 • Instagram’s comments function, which has allowed the Iranian government to threaten dissidents with sexual assault and death as a way of silencing them.2 • TikTok’s powerful recommendation algorithm, which in one experiment promoted violent videos, including incitement of students to launch attacks at school.3 After a case study of January 6 by our collaborators at Tech Policy Press, the report concludes with recommendations for industry and government.
