In 2012, the National Institute of Justice’s (NIJ) Domestic Radicalization to Terrorism program began funding research on issues related to domestic radicalization and terrorism in the United States. NIJ-sponsored research has addressed a variety of factors that can play a role in both facilitating and preventing domestic radicalization, including social networks. This report synthesizes findings from that research, focusing on the role that peer relationships and social dynamics can play as either a gateway to or a gatekeeper preventing radicalization in the United States.

Many researchers, practitioners, and policy-makers continue to raise questions about the role of the Internet in facilitating violent extremism and terrorism. A surge in research on this issue notwithstanding, relatively few empirically grounded analyses are yet available. This chapter provides researchers with five key suggestions for progressing knowledge on the role of the Internet in facilitating violent extremism and terrorism so that we may be better placed to determine the significance of online content and activity in the latter going forward. These five suggestions relate to (1) collecting primary data across multiple types of populations; (2) making archives of violent extremist online content accessible for use by researchers and on user-friendly platforms; (3) outreaching beyond terrorism studies to become acquainted with, for example, the Internet studies literature and engaging in interdisciplinary research with, for example, computer scientists; (4) including former extremists in research projects, either as study participants or project collaborators; and (5) drawing connections between the on- and offline worlds of violent extremists.

While a growing body of evidence suggests that the Internet is a key facilitator of violent extremism, research in this area has rarely incorporated former extremists’ experiences with the Internet when they were involved in violent extremism. To address this gap, in-depth interviews were conducted with ten Canadian former right-wing extremists who were involved in violent racist skinhead groups, with interview questions provided by thirty Canadian law enforcement officials and ten community activists. Participants were asked about their use of the Internet and the connection between their on- and offline worlds during their involvement in the violent right-wing extremist movement. Overall, our study findings highlight the interplay between the Internet and violent extremism as well as the interactions between the on- and offline worlds of violent extremists. We conclude with a discussion of study limitations and avenues for future research.

This chapter critically examines the role that the Internet and the Internet of Things (IoT) play in violent extremism. The chapter specifically focuses on arguments surrounding radicalisation as a pathway to terrorism and how individuals become radicalised due to different radicalisation processes and theories. Based on this critical analysis, the chapter argues that the Internet plays a key role in radicalisation to violent extremism due to several approaches. Issues highlighted in this chapter mainly focusses on the struggles of social media (SM) moderation and regulations. Furthermore, the chapter discusses how the IoT can aid SM regulation to reduce online radicalisation to violent extremism through artificial intelligence (AI) and machine learning (ML) technology. It will be argued how AI and ML could be deployed to reduce terrorist content online, making social media platforms (SMPs) a safer cyber space for individuals to operate within.
