Why more social interactions lead to greater polarization in societies

Posted on November 3rd, 2025 News

Over the last two decades, the number of close social connections has increased significantly—at least by a factor of two. During the same period, societal opinions in many Western countries have become increasingly polarized.
A new study, co-authored by REMASS PI Stefan Thurner, employs a computational model to investigate this connection.
The research demonstrates that above a critical level of social connectivity, societies experience a phase transition leading to explosive polarization. The model accounts for homophily, social balance, and the influence of synchronized influencers, offering a deeper understanding of how modern social dynamics drive polarization.

These findings provide valuable insights into the mechanisms behind growing societal divisions.
