Brian’s research is at the intersection of political psychology, public opinion, and
methodology, with a specific focus on political misinformation, polarization, and
social media. His research agenda centers on questions related to the origins and consequences of misinformation:
what are the cognitive foundations of misinformation, what are its implications for
an increasingly polarized political environment, and how can we slow its spread? In addressing these questions, he draws from theories of social and cognitive psychology
and uses a wide range of methods, including surveys, field experiments, and natural
language processing. His work has been published in the American Journal of Political Science, Proceedings of the National Academy of Sciences, and Public Opinion Quarterly.
