The gap between participation and violence: Why we need to disaggregate terrorist ‘profiles’

Abstract

For decades, practitioners and academics sought to identify a common terrorist “profile.” However, the consensus in both the policy realm and academia suggests that, so far, these efforts produced only modest insights. This research note identifies and addresses a major impediment to previous studies of terrorist profiles: conceptualization. We argue that ambiguities in the definition of the term terrorist lead to an inconsistent and aggregated operationalization in the existing literature. Previous studies attempt to identify the factors correlated with a willingness to commit violence rather than the factors that correlate with the willingness to join an organization that commits violence. We test our claim by disaggregating the roles and responsibilities of members of various Islamist terrorist networks. We provide initial evidence that disaggregation presents a promising first step toward identifying specific profiles for different types of terrorists.
