In fact, the number of far-right attacks continues to outpace all other types of terrorism and domestic violent extremism. This article discusses the findings of several NIJ-supported domestic radicalization studies that cover a range of individual and network-centered risk and protective factors that affect radicalization processes, including military involvement and online environments. The article also explores factors that shape the longevity of radicalization processes and their variation by group structure and crime type, and examines factors that affect pathways away from domestic extremism. It concludes with a discussion of how these findings can inform terrorism prevention strategies, criminal justice policy, and community-based prevention programming.
