Irrespective of discipline, the publication of null or non-significant findings is rare in the social sciences. For burgeoning fields like terrorism research, this is particularly problematic. As well as increasing the likelihood of Type II errors, the selective reporting of significant findings ultimately impedes progression, hindering comprehensive syntheses of evidence…

This pilot study examines the correlation of online and on-the-ground behaviours of three lone-actor terrorists prior to their intended and planned attacks on soft targets in North America and Europe: the Pittsburgh synagogue shooter, the Buffalo supermarket shooter and the Bratislava bar shooter.

The majority of European citizens – often referred to as ‘foreign fighters’ – that have returned to European soil have predominantly been prosecuted for terrorist offences. In recent years several European countries have been prosecuting alleged terrorists cumulatively for both terrorist offences and core international crimes. This paper explores which…

This study explores the motivational drivers of violent extremism by examining references to motivational goals—values—in texts written by lone offenders. We present a new database of manifestos written by lone offenders (N = 103), the Extremist Manifesto Database (EMD). We apply a dictionary approach to examine references to values in this…

This article explores what it is to explain extremism. Rather than providing yet another explanation of extremism, it takes a bird’s eye point of view at existing explanations of extremism. What is it that scholars are doing in seeking explanations of extremism? This article answers this question by considering four issues. First, exactly what is the…

Digital media platforms have been implicated in the recent rise of far-right extremism. This study proposes that these platforms afford emotional processes that lie at the core of far-right movements. Drawing on Randall Collins’ interactional framework and the literature on cultural trauma, we investigate the emotional processes triggered by traumatic…

In recent years, the prevalence of hate speech has become an increasing concern across European societies because of its damaging effect on the very foundation of society and trust between communities. Experts and practitioners have offered a variety of hate speech definitions. For the purpose of this paper, we will…
