  • Biography


    Brian Guay is an incoming Assistant Professor of Political Science at Stony Brook University (beginning in September 2023).

  • Research


    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 ScienceProceedings of the National Academy of Sciences, and Public Opinion Quarterly.
