Jonne Kamphorst | Separation by Degrees: How the Lack of Contact Between the Higher and Lower Educated Causes Political Divides

What explains education-based political divides? Jonne Kamphorst discusses how decreased interactions between higher and lower-educated citizens has widened the political divide between them

Across advanced democracies, education levels are predictive of immigration attitudes and voting for new left or far right parties. What explains education-based political divides? Existing scholarship holds that education causes progressive attitudes, or proposes that being higher educated and holding progressive attitudes can both be explained by socialization during someone’s childhood. This article puts forward an additional explanation. 

We argue that decreased interactions and relationship formation between higher and lower-educated citizens has widened the political divide between them. Using panel and survey data of strong ties, we demonstrate that higher (lower) educated ties make individuals more progressive (conservative). Education divides citizens by providing a distinct worldview for the higher-educated, which is reinforced in increasingly homogeneous education-based networks. Our findings suggest the further crystallization of a cleavage based on education, and highlight the importance of studying networks to understand political behavior.

Jonne Kamphorst is a Postdoctoral Scholar in Political Science at the European University Institute in Florence and a Senior Research Fellow at the Polarization and Social Change Lab at Stanford University. He completed his Ph.D. in Political Science at the EUI in 2023. Before starting his Doctoral Degree, Jonne was a Master’s student in Politics and Sociology at the University of Oxford and the London School of Economics and obtained his Bachelor’s in Political Science from the University of Amsterdam. 

His research, positioned at the intersection between comparative politics and political behavior, explores the roots of political divides in advanced democracies and proposes strategies to bridge them. Two questions define his research agenda: 1) What are the origins of political divisions? And 2) how can democracy be strengthened by re-engaging citizens and building new coalitions of voters that bridge political divides? Jonne answers these questions leveraging quantitative scientific methods. His methodological expertise is in the design, conduct, and analysis of randomized field and survey experiments which he often employs in collaboration with political candidates and parties. He also uses quasi-experimental methods for causal inference. Jonne’s research has been accepted at or been revised and resubmitted to the Journal of Politics, American Political Science Review, and Comparative Political Studies, among other outlets.
