Radicalization is a global event affecting different countries and present in different historical contexts. Psychiatrists can help in the analysis of radicalization in individuals who operate autonomously from more radicalized groups. These lone actors or lone wolves are more difficult to spot as there is no unique identification because they operate as self-determined women or men. A focus of the current study is on the radicalization of children and women. The use of ethnographic research also using Internet sources has provided satisfactory results in the analysis of radicalization while reducing the risk and difficulties of approaching a sample population (terrorists, lone wolves, and radical groups) that, most of the time, is remote, dangerous and concealed to public scrutiny. Emphasis is also provided to the stages of development of radicalized thought and how radicalization can be understood in terms of cognitive and social development of the lone-wolf terrorist. The authors also explore how a radicalized leader can lever on the vulnerability of some individuals to radicalize them. Besides, the authors approach radicalized thought also as a logical fallacy and as a sign of dualistic thinking. Hence, a mix of cognitive, logical, and psychiatric triggers is analyzed in their potential to radicalize.
