This systematic review seeks to position online radicalisation within whole system frameworks incorporating individual, family, community and wider structural influences, whilst reporting evidence of public mental health approaches for individuals engaging in radical online content. Methods: Authors searched Medline (via Ovid), PsycInfo (via Ebscohost) and Web of Science (Core Collection), with the use of Boolean operators across ‘extremism’, ‘online content’, and ‘intervention’. Results: Following assessment of full text, all retrieved papers had to be excluded. Results from six excluded articles which did not fit inclusion criteria but identified theoretical relationships between all three elements of online extremism, psychological outcomes, and intervention strategy, were discussed. Authors found no articles outlining public mental health approaches to specifically online radicalisation. Conclusions: There is an immediate need for further research in this field given the increase in different factions of radicalised beliefs resulting from online, particularly social media, usage.

This article assesses the cases that have come to light since 9/11 of Islamist extremist terrorism, whether based in the United States or abroad, in which the United States itself has been, or apparently has been, targeted. Information from them is used to evaluate how the Internet (including various forms of electronic communication) has affected several aspects of the terrorism enterprise in the United States: radicalization, communication, organization, and the gathering of information. In general, it is found that the Internet has not been particularly important. Although it has been facilitating in some respects, it has scarcely ever been necessary. In some respects, the Internet more fully aids efforts to police terrorism – although this is mainly due to the incompetence and amateurishness of would-be terrorists. In other respects, however, the Internet, and the big data compilations it makes possible, greatly increase the costs and complications of the counterterrorism quest.

John Mueller examines the degree to which the cybercoaching of terrorists should be cause for concern, arguing that in
many cases cybercoaches have little control over their amateurish charges.

How does the internet affect the radicalisation of extreme-right lone actor terrorists? In the absence of an established theoretical model, this article identifies six mechanisms seen as particularly relevant for explaining online radicalisation. Having first reviewed a larger set of relevant lone actor terrorists, the study traces these mechanisms in three selected cases where the internet was reportedly used extensively during radicalisation. The findings show that the internet primarily facilitated radicalisation through information provision, as well as amplifying group polarisation and legitimising extreme ideology and violence through echoing. In all three cases, radicalisation was also affected considerably by offline push-factors that through their presence made extreme online messages more impactful. The results challenge the view that offline interaction is necessary for radicalisation to occur but also the view that online influence itself is sufficient.
