Although researchers know a great deal about persuasive messages that encourage terrorism, they know far less about persuasive messages that denounce terrorism and little about how these two sides come together. We propose a conceptualization that distinguishes a message’s support for an act from its support for the ideology underlying an act. Our prediction is ...

It is commonly recognized that social media presents vast new opportunities for terrorist groups seeking to radicalize audiences. However, few scholars have studied the actual mechanisms by which radicalizing messages are delivered to those audiences. Within this paper, the author explores one key aspect of the phenomenon of ‘jihadi cool’ – that is, the rendering ...

Recent terrorist attacks carried out on behalf of ISIS on American and European soil by lone wolf attackers or sleeper cells remind us of the importance of understanding the dynamics of radicalization mediated by social media communication channels. In this paper, we shed light on the social media activity of a group of twenty-five thousand ...

Widespread Internet use by terrorists had made the prevention of terror attacks increasingly difficult. This Article argues that social media companies, like other corporate entities, should be legally required to institute compliance programs that ferret out and report terrorist activity at the earliest possible opportunity. To this end, the Article proposes text for new legislation ...

Employing social network analysis, this article investigates  the  transnational communication network and discourse of political-Salafists on social media. It examines whether political-Salafists across the MENA region have a common sociopolitical and geopolitical agenda, and whether – given the recent shift of some political-Salafists towards violence – their discourse and communication network can still be distinguished ...

In the wake of devastating attacks by violent extremists around the world, policy makers have invested considerable effort into understanding terrorists’ use of the Internet as they radicalize and mobilize to violence. To that end, the article “Terrorist Use of the Internet by the Numbers: Quantifying Behaviors, Patterns, and Processes” by Paul Gill, Emily Corner, ...

Public interest and policy debates surrounding the role of the Internet in terrorist activities is increasing. Criminology has said very little on the matter. By using a unique data set of 223 convicted United Kingdom–based terrorists, this article focuses on how they used the Internet in the commission of their crimes. As most samples of ...

Weeks after its capture of Mosul in 2014, the Islamic State set about transforming its strategic trajectory. Through an avalanche of media products, it worked to aggressively insert itself into the global public discourse and, in turn, popularise its brand, polarise adversary populations and drive rivals into the ideological side-lines. This research paper presents new, empirical insight ...

Using a dataset of over 1.9 million messages posted on Twitter by about 25,000 ISIS members, we explore how ISIS makes use of social media to spread its propaganda and to recruit militants from the Arab world and across the globe. By distinguishing between violence-driven, theological, and sectarian content, we trace the connection between online ...

To date there have been almost no efforts to merge these frameworks, though terrorism shares common characteristics of deviant subcultures. Both are driven by ideologies that are in opposition to that of ...
