The Internet is often singled out as the key means through which extremists and terrorists are radicalised. Yet, argue Charlie Edwards and Luke Gribbon, research thus far has fallen short of unearthing the actual mechanisms through which this radicalisation takes place. Using examples from a wider study, they explore different ways in which individuals have used the Internet in their processes of radicalisation and point out that policy-makers and researchers need to focus their efforts on understanding not merely the content that is available online, but the ways in which this content is used in the process of radicalisation.
