Terrorism

Terrorism encompasses the deliberate use or threat of violence by non-state actors to instil fear, influence broader audiences and compel governments or societies towards political, ideological or religious ends. Modern research highlights its transnational reach, the role of social media in recruitment and propaganda, and the interplay between online radicalisation and offline mobilisation. Extremist groups exploit algorithmic curation on digital platforms, creating echo chambers that reinforce grievance narratives and dehumanise targets. They weave diagnostic frames (identifying problems), prognostic frames (advocating solutions) and motivational frames (calling to action) into coherent discourses that can rapidly spread across mainstream and alternative venues. At the same time, shifts in organisational structure—from centralised hierarchies to networked cells—have made detection and disruption more complex. Counter-terrorism efforts now combine hard measures (intelligence-led operations, asset freezes, no-fly zones) with soft measures (community engagement, counter-messaging, de-radicalisation programmes), balancing security needs with human rights and free-expression concerns. The challenge remains to design interventions that pre-empt violent acts without amplifying extremist worldviews, while fostering resilience in pluralistic societies.

Research from Nature Portfolio

Recent studies have examined the emergence of hybrid self-improvement rhetoric on anonymous image-boards, showing how far-right posts on fitness, discipline and personal betterment co-opt fascist iconography to groom recruits into survivalist cells. This “iron-pill” genre draws on fascist history and self-help tropes, transforming idle agitators into committed activists by framing personal transformation as resistance against imagined tyranny. Analyses reveal that these threads not only disseminate conspiratorial worldviews but foster embodied practices—diet, exercise, martial arts—that cement group identity and lower psychological barriers to violence. The work calls for nuanced monitoring of ideological frictions on fringe platforms and for tailored counter-narratives that decouple personal empowerment from extremist political agendas.

Technical terms

Algorithmic curation: the process by which platform algorithms select and prioritise content, sometimes amplifying extreme material unintentionally.

Echo chamber: a self-reinforcing online environment where users encounter only like-minded views, solidifying pre-existing beliefs.

Self-improvement radicalisation: the fusion of personal betterment advice (diet, fitness, productivity) with extremist ideology to spur commitment.

Alt-tech platform: a social network that positions itself as resistant to mainstream moderation and often attracts more extreme voices.

Violence cues: linguistic or symbolic triggers in messaging that explicitly call for or celebrate violent action.
