About Book

This report by Scott Helfstein explores radicalization as both an ideological and social process, emphasizing its coevolutionary nature. It argues that violent extremism cannot be explained solely by ideology or social dynamics but through the interplay between the two. The study highlights how radical ideas resonate with aggrieved groups, how individuals adopt and spread those ideas through networks, and the influence of technology in accelerating radicalization. By examining these mechanisms, the report provides valuable insights for understanding the persistence of terrorist threats against the U.S. and globally.
