摘要：What lessons can the study of fundamentalism and the psychology of religion teach the newer field ofRadicalization and Involvement in Violent Extremism (RIVE). Four lessons and an intervention areoffered in this article: (1) Religion is a robust human experience and cultural product that adopts adefensive shape when its worldview is threatened. (2) This does not mean that all "fundamentalisms"or radical versions of religion are somehow linked or perform similar functions; rather, they reflectthe limited human repertoire to threat, yet within different cultural and historical contexts. (3) Causalexplanations on the level of the individual are insufficient to understand these movements. (4) Thereis a modernist trend to elevate word-based, rational knowing over more implicit, symbolic knowing inboth fundamentalism and radical discourses. Fundamentalism and radicalized religion seem to be theleft brain's attempt to"do" religion. And, it does this now even more separately from the right braincompared to previous eras.1 (5) An intervention addressing violent extremisms through valuecomplexity draws the above lessons together in an emergentist model that has an empirical trackrecord of success
