This article identifies themes and issues that seem to cause doubt, leading to exit. It then provides an overview of the literature on disengagement, which has increased in recent times, identifying research findings into voluntary exit from violent extremism: losing faith in the militant ideology, group and leadership failure, and personal practical circumstances. Social psychology and research into persuasion and attitude are used to provide a perspective on how these natural sources of doubt might best be brought to bear in connection with an exit program. The article concludes that an external intervention should stay close to the potential exiter’s own doubt, make the influence attempt as subtle as possible, use narratives and self-affirmatory strategies to reduce resistance to persuasion, and consider the possibility to promote attitudinal change via behavioral change as an alternative to seek to influence beliefs directly.
