ABSTRACT
Within the broader discussion of US domestic terrorism, the impact of formal extremist groups on the behaviour of perpetrators of ideologically motivated crime stands as a key albeit under examined issue. Radicalization and terrorism have long been understood as group-driven processes, yet the degree and rate of group affiliation among US extremist offenders is highly variable, especially in the context of rising instances of lone actor attacks. This raises the question of the role that group affiliation plays in relation to perpetrators of extremist violence. For while discourse surrounding domestic terrorism has largely classified these organizations as facilitators or enablers of radicalization and extremist violence, patterns in recent years suggest these groups may in fact do the opposite and dampen the violent impulses of their members to preserve their organizational interests. This paper presents an analysis of data adapted from the Profiles of Individual Radicalization in the United States (PIRUS) dataset as well as original data and finds that membership in formal extremist groups does appear to create a moderating effect on perpetrators of ideologically motivated crime, reducing the probability of group members in engaging in violence.

Notes
1. Hypothesis 1: Among perpetrators of ideologically motivated crime, individuals who are members of formal extremist organizations or movements are less likely to commit acts of indiscriminate violence.
2. Hypothesis 2: Among perpetrators of ideologically motivated crime, individuals who are members of formal extremist organizations or movements are less likely to be involved in plots that would result in high levels of lethality.
