In this study, and with a view to extending upon existing findings on the effects of general violent media on violent cognitions, we experimentally measured the relationship between exposure to extremist propaganda and violent cognitions. Our results countered our hypotheses and the wider findings of violent media and aggression that exposure to violent stimuli increases violent thoughts and that this effect is moderated by trait aggression. Specifically, this study found that participants with low and medium trait aggression became more pro-social after being exposed to extremist propaganda. We discuss these results with reference to theories of terror management and mortality salience, as well as the implications of these results for wider theories of the role of online extremist material in the wider “radicalization” process.

The development of the Internet and social media has exploded in the last couple of years. Digital environments such as social media and discussion forums provide an effective method of communication and are used by various groups in our societies.  For example, violent extremist groups use social media platforms for recruiting, training, and communicating with their followers, supporters, and donors. Analyzing social media is an important task for law enforcement agencies in order to detect activity and individuals that might pose a threat towards the security of the society.

In this thesis, a set of different technologies that can be used to analyze digital environments from a security perspective are presented. Due to the nature of the problems that are studied, the research is interdisciplinary, and knowledge from terrorism research, psychology, and computer science are required. The research is divided into three different themes. Each theme summarizes the research that has been done in a specific area. The first theme focuses on analyzing digital environments and phenomena. The theme consists of three different studies. The first study is about the possibilities to detect propaganda from the Islamic State on Twitter.  The second study focuses on identifying references to a narrative containing xenophobic and conspiratorial stereotypes in alternative immigration critic media. In the third study, we have defined a set of linguistic features that we view as markers of a radicalization.

This article is concerned with the distinction between acceptable race talk in social media and organised, extreme or ‘frozen’ racism which is considered hate speech and removed. While in the literature this distinction is used to point to different variants, styles and mutations of racism, in social media platforms and in European regulatory frameworks it becomes policy. The empirical part of the article considers this distinction drawing upon a series of posts following a stabbing incident in a small Irish town, which organised Twitter accounts sought to connect to terrorism. The empirical analysis examines the tweets of those accounts and the comments left on the Facebook page and website of one of the main Irish online news outlets. The analysis shows few if any differences between the two, concluding that there is a blending of supremacist and everyday, ambient racist discourses. This blending indicates the operation of a transnational contagion, given the shared vocabularies and discourses. It further problematises the distinction between ‘illegal hate speech’ and ‘acceptable race talk’, and throws into question the principle underlying both the policies of social media as well as the European efforts to de-toxify the digital public sphere.

This article is concerned with identifying the ideological and techno-material parameters that inform Facebook’s approach to racism and racist contents. The analysis aims to contribute to studies of digital racism by showing Facebook’s ideological position on racism and identifying its implications. To understand Facebook’s approach to racism, the article deconstructs its governance structures, locating racism as a sub-category of hate speech. The key findings show that Facebook adopts a post-racial, race-blind approach that does not consider history and material differences, while its main focus is on enforcement, data, and efficiency. In making sense of these findings, we argue that Facebook’s content governance turns hate speech from a question of ethics, politics, and justice into a technical and logistical problem. Secondly, it socializes users into developing behaviors/contents that adapt to race-blindness, leading to the circulation of a kind of flexible racism. Finally, it spreads this approach from Silicon Valley to the rest of the world.

Amid mounting death tolls in Iraq, Syria, and Yemen, sectarian discourse is
on the rise across the Arab world—particularly in the online sphere, where
extremist voices are amplified and violent imagery and rhetoric spreads rapidly.
Despite this, social media also provides a space for cross-sectarian discourse
and activism. Analysis of over 7 million Arabic tweets from February to August
2015 suggests that violent events and social network structures play key roles
in the transmission of this sectarian and countersectarian rhetoric on Twitter.
