Social Media

A society-wide failure of algorithmic transparency is currently perpetuating innumerable social, economic and health related risks around the world. While algorithms play a role in the proliferation of extremism online — be it white nationalism or other toxic social phenomena — we know very little about how these algorithms operate and how their operation is affecting users; researchers have no robust way to probe how or why extremism emerges and the role that algorithms play in its development. Our team is working on causal investigations of algorithmic responses to user behavior and the evolving dialectic between user behavior and algorithmic recommendations.

Trajectories of YouTube consumption based on content exposure over time

What influence do YouTube algorithms have on political thought and radicalization? Researchers take a new approach, mapping content and users in a multi-dimensional space based on more granular information about their consumption than previous studies – in particular, the signals embedded in videos' scripts.
