Despite theory treating radicalization as a process, most quantitative studies are cross-sectional

Evidence

Apart from providing an inventory of identity concepts as predictors of extremist radicalization, this review demonstrates that, although radicalization is commonly referred to as a process, most quantitative studies on the putative effect of identity employed a cross-sectional research design and only collected data at one point in time. As a result, most studies in this review cannot draw any conclusions regarding the role the various identity concepts play at the different stages of radicalization, including whether they are a cause or part of it. — Lea Echelmeyer, Anne-Marie Slotboom, and Frank Weerman, The Putative Effect of Identity on…, 256
