This portal assembles recent research on violent extremism and social media. The relationship between violent extremism and social media is contested. When it comes to ‘cause-effect’ research, some argue that social media amplifies, extends and empowers violent extremism. Social media may lower the bar for participation, enable lone wolves to embrace transnational extremist movements, facilitate recruitment, enforce fear and control. Others are more skeptical of the power of social media, on its own. It is a fact, however, that extremist groups leave behind digital footprints – information about who they are, what they do, where they do it, and who is paying attention. Some of this data could have significant potential for the prevention of violent extremism. But research is in its infancy. Methodological challenges and ethical concerns loom large. This portal is to help CVE researchers to quickly find recent research on the threats and potential of social media in the fight against violent extremism. The portal’s creation was funded by a grant from Public Safety Canada’s Kanishka Project.
