Abstract for: The dynamic radicalization process and violent behaviour of Incels

Involuntarily Celibates (Incels) are part of an online community, often associated with sexist and misogynistic beliefs. Recent years have shown a rise in members and, more generally, in men identifying with these ideas. As a previously mostly non-violent group, the rise in members who support and encourage violence has raised concerns about public safety. The question is: how do different factors contribute to the radicalization process of Incels? And which factors aid the shift towards violence. In order to better understand these questions, and considering the complex and dynamic nature of the radicalization process, the System Dynamics method was chosen. An explanatory simulation model was developed to represent the real-world process of coming into contact with Incel related content, radicalizing into an Incel, and committing violence. The process of deradicalization, of leaving the Incel community behind, was also represented. In order to reduce and prevent a further increase in Incel members and violence, several interventions have been tested. These interventions supported the deradicalization process and aimed to limit the number of men radicalizing into Incels, by introducing mental health services and banning Incel posts on websites. Based on the findings of the model, supporting the deradicalization process and offering mental health services offer the most promising results in reducing the amount of Incels and the violent attacks.
