Right-Wing Twitter Users in France Exhibit Growing Homophily Compared With Left and Center Users

Abstract

The purpose of this research is to enhance our understanding of homophilic behaviors—where individuals prefer to associate with others like themselves—on Twitter, particularly focusing on how these behaviors vary across different political affiliations. While a general increase in homophily is a well-documented phenomenon in social networks, its expression within the diverse political contexts on Twitter remains underexplored. This study seeks to understand how political alignment influences homophily and its possible role in reinforcing extreme viewpoints. In particular, the research examines the patterns of interaction within political communities on French Twitter, delineating between right-wing, left-wing, and centrist groups. The findings reveal a significant pattern: right-wing groups demonstrate a marked increase in homophily over time, suggesting a stronger predilection for in-group interaction when compared with their centrist and left-wing counterparts. In addition, the study monitors the evolution of follower networks among these political clusters, providing insights into the shifting popularity of political parties within each group. By analyzing the social connections within these clusters, the study offers a detailed perspective on the dynamics of political homophily on Twitter and how it evolves, informing our understanding of political communication and group behavior in the digital age.
