What is the best approach for preventing recruitment to terrorism? Findings from ABM experiments in social and situational prevention

Abstract

This study uses agent-based models (ABMs) to compare the impacts of three different types of interventions targeting recruitment to terrorism - community workers at community centers; community-oriented policing; and an employment program for high-risk agents. The first two programs are social interventions that focus on de-radicalization and changing the dispositions of agents in the model, whereas the employment program focuses on "deflection" and represents a situational/opportunity reducing approach to prevention. The results show significant impacts of the community worker and community policing interventions on radicalization but no significant impact on recruitment. In contrast, the employment intervention had a strong and significant impact on recruitment, but little impact on radicalization.
