The U.S. Department of Justice (DOJ) has published a report that summarizes the findings of various DOJ projects on how individuals become radicalized to terrorism and their implications for community members performing prevention and intervention efforts. The projects studied for this summary report involve a wide range of groups and individuals who support and commit ideologically motivated violence to further political, social, or religious goals, including Islamist terrorists but also those associated with anti-government, anti-capitalist, nativist, and other political and social terrorist movements. In addition to identifying several common facilitators of radicalization to terrorism, the research conducted through these projects provides empirical evidence that individuals' processes of radicalization to terrorism may vary by the extremist ideologies and narratives they embrace, the time periods in which they radicalize, the groups or movements they join (or do not join, in the case of lone actors), and/or their individual characteristics and experiences.
