A multiplex network approach to understanding extremist organizations: A case study of the Proud Boys

Abstract

Purpose

This paper explores the network dynamics of extremist organizations through a detailed case study of the Proud Boys. Using a multiplex network approach, informed by recent advances in research on gangs, we examine how various types of ties influence extremist behavior.

Method

We first describe three focal networks through which the Proud Boys operate – chapter affiliations, online connectivity through social media, and co-membership in other extremist groups – and the resultant multiplex network linking members across the organization. We then describe a fourth network of offline co-activism and use multiple regression with the quadratic assignment procedure (MRQAP) to assess how ties within different multiplex network layers are associated with co-activism.

Results

Findings indicate high variability in member connectivity across different types of ties, but certain metrics do reveal key figures within the organization. Each focal network is significantly associated with co-activism. Regional proximity and shared leadership roles also emerge as relevant factors, underscoring the potential influence of structural and organizational dynamics.

Conclusion

This study provides a nuanced understanding of the structure and linkages within an extremist organization, demonstrates the value of a gang-informed approach, and offers insight into the drivers of extremist mobilization.
