Lilliana Mason

Lilliana Mason is a political scientist and associate professor at Johns Hopkins University's SNF Agora Institute and Department of Political Science. She specializes in studying political psychology, identity politics, and partisan polarization in American politics. Mason's most prominent work is her 2018 book "Uncivil Agreement: How Politics Became Our Identity," which examines how social identities have become increasingly aligned with political parties in the United States. Her research demonstrates how this "social sorting" has led to heightened emotional reactions to politics and increased hostility between Democrats and Republicans. Her academic contributions include influential studies on political identity, group dynamics, and the emotional aspects of partisan conflict. Mason's work has appeared in leading academic journals including American Political Science Review and American Journal of Political Science. Mason regularly provides expert commentary on political polarization for major media outlets and has received recognition for making complex political science concepts accessible to general audiences. Her research continues to focus on understanding the psychological and social dynamics that drive political divisions in contemporary American society.

Katherine Cramer focuses on rural-urban divides in American political identity and how place-based resentments shape partisan attitudes. Her field research methods and examination of social identity in politics parallel Mason's work on partisan polarization.

Diana Mutz studies how cross-cutting political exposure and social networks influence political behavior and attitudes. Her research on affective polarization and political communication provides complementary insights to Mason's work on partisan identity.

Alan Abramowitz analyzes the causes and consequences of ideological polarization in American politics through quantitative research. His examination of how social sorting drives political division builds on similar themes in Mason's research.

Marc Hetherington examines how personality traits and authoritarianism relate to political preferences and partisan identity. His research on the psychological foundations of political behavior connects with Mason's work on identity-based polarization.

Samara Klar investigates how social identity and group dynamics shape political behavior and partisan attachments. Her research on independent political identities and social pressure in politics addresses similar questions about identity and polarization that Mason explores.
