Radicalized French citizens who adhere to Islamic State propaganda are less likely to disengage from their beliefs if they are married men with children, and from families with married parents. This is according to Nicolas Campelo of the Pitié-Salpêtrière Hospital in France, who led a study in the journal Palgrave Communications which is published by Springer Nature. The research identified important factors that were accountable for someone being radicalised, such as having an interest in violence, or experiencing feelings of depression, uncertainty or loneliness. The findings also show that these radicalized individuals most likely tried to influence other family members or friends, and often had a close friend or relative in prison.
