An epistemic break from “expertise”: Misunderstanding Terrorism by Marc Sageman

Professor Marc Sageman’s latest contribution to terrorism “studies” builds on an ever-increasing critique of a field in which “expertise” is something that is largely taken for granted, rather than empirically “known”. His book Misunderstanding Terrorism seeks to refocus our attention towards what is knowable through a Bayesian analysis based on his unique access to acts of terrorism within the Western world. Key, however, is his framing of what terrorism “is”, and to that effect, this review article first assesses the work of two individuals writing on terrorism, Rafaello Pantucci and Shiraz Maher, to place Sageman’s significant book within a wider context of terrorism literature.
