Understanding and preventing internet-facilitated radicalisation

This paper reviews available research on how the internet facilitates radicalisation and measures to prevent it. It briefly canvasses evidence on the extent to which the internet contributes to radicalisation broadly, and who is most susceptible to its influence, before delving further into the mechanisms underpinning the relationship between the internet and violent extremism. High-level approaches to combating internet-facilitated radicalisation, including content removal, account suspensions, reducing anonymity, and counternarrative and education campaigns, are mapped against these mechanisms. This illustrates how these approaches can disrupt radicalisation and assists researchers, policymakers and practitioners to identify potential gaps in existing counterterrorism and countering violent extremism regimes. Research on the implementation and outcomes of these approaches is also summarised.
