Are the mechanisms and processes that lead to radicalization different for Muslim converts and non-converts in the United States? While many scholars attempt to explain why people violently radicalize, the theories are diverse and most treat converts and non-converts the same. This
study answers this question by categorizing the many radicalization theories into three levels of analysis so that cases of radicalization can be analyzed across and within disciplines. Out of 83 cases studies, individual-level factors are more prevalent among converts than non-converts. Group-level
processes similarly affect both groups. Mass-level mechanisms are not significant factors in radicalization.
