Radicalization factors are non-deterministic and heterogeneous across individuals

Evidence

Existing work highlights individual, familial, and community, social, and cultural factors that have been hypothesized to be associated with radicalization. However, caution should be raised when attributing any of these factors with radicalization, as many of the factors are common in the population (and therefore not deterministic) and may influence different parts of a person’s journey into extremism or may be indirectly associated with extremism. The literature also indicates heterogeneity in pathways to radicalization and, for those who leave extremist groups, heterogeneity in deradicalization. — Ryan Andrew Brown, Todd C.
