Neurodiversity and Radicalisation – Resilience in Unity (Online)

Exploited Vulnerabilities

The intersection of neurodiversity and radicalisation has gained prominence due to a surge in online extremism post-2020. Social media algorithms amplify exposure to hateful content, particularly for isolated individuals. Neurodivergent traits, such as intense focus or difficulty in social discernment, can be manipulated by extremists offering a false sense of belonging. This trend accelerated during lockdowns, when online engagement spiked.

In the UK, the Prevent programme's 2025 statistics highlight the scale: of 8,778 referrals, 1,226 involved Autistic Spectrum Disorder. This over-representation stems from misinterpreting autistic behaviours—like special interests in historical events—as signs of radicalisation. Affected groups include young males, often from marginalised communities, facing real-world harms like school referrals or police scrutiny. Globally, similar patterns emerge in Australia and the US, where neurodivergent youth feature in rising extremism cases.

Stakes are high with concrete risks. Inaction could lead to incidents like the 2021 Plymouth shooting, linked to incel ideology and undiagnosed neurodivergence. Costs mount through expanded counter-terrorism budgets—UK's Prevent funding exceeded £40 million in 2025—plus long-term mental health support needs. Deadlines loom with ongoing reviews, such as the Home Office's 2025 autism audit in Prevent, set for completion by mid-2026. Consequences of mishandling include deepened isolation for neurodivergent people, eroding trust in authorities.

Non-obvious tensions arise between safeguarding and stigmatisation. Critics argue Prevent pathologises autism, with 2025 reports showing disproportionate referrals of autistic children, sometimes for benign interests like researching historical figures. Trade-offs include balancing algorithmic regulation—EU's Digital Services Act fines platforms up to 6% of global turnover for failing to curb extremism—against free speech concerns. Counterarguments note that while vulnerabilities exist, most neurodivergent individuals reject extremism, with resilience factors like structured support underrepresented in discourse.

Surprising data from 2026 reviews indicate ADHD alongside autism as key factors, with combined neurodivergence in one-third of cases. This underscores broader systemic issues: underfunded services leave gaps extremists exploit. In Australia, 2025 cases revealed authorities sometimes exacerbating risks through mishandled interventions, highlighting the need for neurodiversity-aware training.
