Title: How Do Social Media Algorithms Affect Platform Use, Attitudes and Behavior?
Policymakers and the public are increasingly interested in the effects of social media algorithms on society. In this talk, I outline some of the challenges this topic poses to researchers. I then introduce an approach to studying these systems’ effects on individuals: a large-scale collaboration with Meta during the 2020 U.S. presidential campaign. Focusing on experiments designed to change how posts were ranked in users’ feeds, I explore how our treatments altered the types of content users saw. Among the categories we analyze are political news, posts from like-minded (vs. cross-cutting) sources, and posts from sources deemed untrustworthy. Finally, I discuss the effects of our treatments on individuals’ political behavior, knowledge, and attitudes.
