Mary McGrath

Assistant Professor of Political Science

PhD, Yale University, 2016

Political scientist Mary McGrath looks into the balance of reason and reflex underpinning our actions and beliefs: What commonalities are we able to uncover in how we evaluate and respond to the world around us? This has translated into a research agenda that covers American politics, political psychology and behavior, and political economy. She uses a range of quantitative methods to investigate processes of political and economic decision-making, opinion formation, and belief.

McGrath’s research has been published in The Annals of the American Academy of Political and Social Science, the Quarterly Journal of Political Science, and the Election Law Journal: Rules, Politics, and Policy. Her doctoral dissertation examined how collaboration shapes political behavior, looking at collaborative rhetoric and the relationship between perceptions of group identity and collaboration.

McGrath received her PhD in political science from Yale University, where she was a graduate fellow at the Institution for Social and Policy Studies.

Current Research

How Does Collaboration Affect Political Interactions? McGrath seeks to understand how collaboration shapes political interactions and engagement, asking the following key questions: Does collaboration increase tolerance toward the collaborator? Does it increase trust? Are collaborators more persuasive? In an on-going project, McGrath investigates these questions in the context of civic education, community-oriented policing, and climate change.

Demand-Side Contributions to the Partisan Gender-Gap in Office. Do voters exhibit biases based on candidate gender, and if so, could partisan differences in candidate-gender bias contribute to the partisan gender-gap in office-holding? What explains candidate-gender bias? Is candidate-gender used as a proxy for relevant information, or is this bias a manifestation of prejudice unrelated to political reasoning.
