“…A total of 4011 French individuals were registered for radicalization, including 1017 minors (25%), 1434 females (35%), and 1672 (42%) convert Muslims (Ciotti and Menucci, 2015). To tackle the phenomenon of radicalization among young Europeans, authors have suggested individual risk factors such as personal vulnerabilities (e.g., early experiences of abandonment, perceived injustice, personal uncertainty and perceived group threat) and psychiatric disorders (Bazex et al 2017;Doosje et al 2013); micro-environmental risk factors such as family dysfunction and friendships with radicalized individuals (Bazex et al 2017;MIVILUDES, 2015;Schuurman and Horgan, 2016;Van San et al 2013); societal risk factors such as geopolitical events, societal polarization and societal changes (Benslama, 2016;Coid et al 2016;O'Duffy, 2008;Wiktorowicz, 2005); and systemic factors such as an encounter between an individual who is a candidate for becoming radicalized and a recruiter who uses sectarian techniques to isolate and dehumanize the candidate (Bouzar, 2014;MIVILUDES, 2015). However, recent reviews have highlighted that studies with empirical data are limited; they are mainly based on either small samples of males involved in terror attacks or projects (Bazex et al 2017), i.e., a retrospective design (Veldhuis and Staun, 2009), or Muslim by birth individuals (Kundnani, 2015), making it impossible to generalize the results or to establish causal relations.…”
