Major events trigger waves of radicalization across different ideologies

Evidence

Additionally, several studies argue that radicalization in the United States generally occurs in waves that correspond with the rise of different ideologies (i.e., Islamist, far-right, and far-left ideologies). The attacks of 9/11, for instance, were a clear trigger for Islamic extremism becoming more widespread in the United States. This suggests a sort of group-think-driven momentum behind the prevalence and propagation of ideologies. — Ryan Andrew Brown, Todd C. Helmus, Rajeev Ramchand, Alina I.
