This paper uses automated text analysis – the process by which unstructured text is extracted, organised and processed into a meaningful format – to develop tools capable of analysing
Islamic State (IS) propaganda at scale. Although we have used a static archive of IS material, the underlying principle is that these techniques can be deployed against content produced by any number of violent extremist movements in real‑time. This study therefore aims to complement work that looks at technology‑driven strategies employed by social media, video‑hosting and file‑sharing platforms to tackle violent extremist content disseminators.

Right-wing extremists and Islamist extremists try to recruit new followers by addressing their national (for instance, German) or religious (Muslim) social identity via online propaganda videos. Two studies examined whether capitalizing on a shared group-membership affects the emotional and cognitive response towards extremist propaganda. In both studies, Germans/non-migrants, Muslim migrants and control participants (N = 235) were confronted with right-wing extremist and Islamist extremist videos. Emotional and cognitive effects of students (Study 1) and apprentices (Study 2) were assessed. Results showed a general negative evaluation of extremist videos. More relevant, in-group propaganda led to more emotional costs in both studies. Yet, the responses varied depending on educational level: students reported more negative emotions and cognitions after in-group directed videos, while apprentices reported more positive emotions and cognitions after in-group directed propaganda. Results are discussed considering negative social identities.

Viral online disinformation is misleading content that is generated to manipulate public opinion and to circulate rapidly in the digital space. Although viral disinformation has become an instrument for radicalization, the specific psychological mechanisms by which disinformation can be weaponized––wielded as mobilizing and radicalizing political tools––are not yet well-understood.

In this paper, we establish the potential of concerted disinformation efforts to impact mass radicalization and political violence, first through historical precedents of deadly disinformation campaigns, then in modern-day examples from the USA and Russia. Comparing and contrasting political effects of two recent disinformation campaigns, QAnon’s #SaveTheChildren campaign in the USA, and anti-LGBTQ disinformation campaign in Russia, this paper highlights the significance of LGBTQ contagion threat—a notion that people can be “turned” into LGBTQ through deliberate outside influence. The psychological and political consequences of such messaging, its main target audience, and vulnerability factors rendering individuals especially susceptible to its radicalizing effects are discussed.
