About the event
Radicalized groups used to be relatively clearly ideologically delineated: think of the belief-system of the Red Army Faction, ISIS, Al Quaeda, or various neo-Nazi groups. Nowadays, we witness how actors select from existing ideologies and eclectically compose their own belief-system. Moreover, we see various kinds of radical groups, such as Exctinction Rebellion, using extreme methods that are not violent but deeply disruptive. Finally, we note how various individuals and groups can blend conspiracist, fanaticist, extremist, and fundamentalist aspects of existing movements, making it hard to locate them on scales and measures of radicalization. All this raises the question: where to draw the line between extreme and extremist, between radical and radicalized? Is there a principled way to do so or is it simply a matter of perspective? In this lecture, I introduce the SAR (Subject-Axis-Result) Model of Radicalization and show how it helps us to distinguish radicalism from radicalization. I also lay out what this means for practitioners, in particular in preventing and countering radicalization.
