what is radicalisation
Radicalization (or radicalisation) is a process by which an individual or group comes to adopt increasingly extreme political, social, or religious ideals and aspirations that (1) reject or undermine the status quo or (2) reject and/or undermine contemporary ideas and expressions of freedom of choice.li Berman 's 2009 book Radical, Religious, and Violent: the New Economics of Terrorism applies a rational choice model to the process of radicalization, demonstrating that the presence of mutual aid networks increase the resilience of radical groups.
