Although there is no direct link between autism and violent extremism in the general population, some autistic individuals become radicalised and engage in extremist activities. This research adopted a case study analysis approach, analysing a novel dataset of 18 closed-source international cases of individuals with extremism concerns who were diagnosed with, or undergoing diagnosis for, autism. The cases were synthesised and aggregated using the FARAS to identify common patterns (as well as any differences) across the cases.
