Collective Identity Radicalization and the Transition to Violent Action

Collective action, radical belief, and preparation for violence are different phenomena. Their conflation can weaken research and encourage disproportionate responses to lawful participation. This conceptual article develops Chapter 9 of the source manuscript through a focused narrative review of social identity, radicalization mechanisms, and conspiracy belief. It asks how changes in group norms and personal participation can be examined without constructing an ideological profile of dangerousness. The analysis proposes separate dimensions for belief, belonging, intention, capability, and action. An original behavioral transition framework is developed, followed by a prospective mixed-method research design using voluntary participation and non-operational scenarios. No extremist groups, private communications, or individual threat cases were investigated. The article argues that research should test specific transitions and opportunities for disengagement rather than assume a universal radicalization sequence. Its central conclusion is that behavioral specificity and protection of lawful dissent are necessary for both explanatory validity and legitimate prevention.
