                                    Discourse patterns used by extremist Salafists on Facebook: identifying potential triggers to cognitive biases in radicalized content

                                                        Understanding how extremist Salafists communicate, and not only what, is key to gaining insights into the ways they construct their social order and use psychological forces to radicalize potential sympathizers on social media. With a view to contributing to the existing body of research which mainly focuses on terrorist organizations, we analyzed accounts that advocate violent jihad without supporting (at least publicly) any terrorist group and hence might be able to reach a large and not yet radicalized audience. We constructed a critical multimodal and multidisciplinary framework of discourse patterns that may work as potential triggers to a selection of key cognitive biases and we applied it to a corpus of Facebook posts published by seven extremist Salafists. Results reveal how these posts are either based on an intense crisis construct (through negative outgroup nomination, intensification and emotion) or on simplistic solutions composed of taken-for-granted statements. Devoid of any grey zone, these posts do not seek to convince the reader; polarization is framed as a presuppositional established reality. These observations reveal that extremist Salafist communication is constructed in a way that may trigger specific cognitive biases, which are discussed in the paper.

                                                        The perceived threat of extremist online propaganda has generated a need for countermeasures applicable to large audiences. The dissemination of videos designed to counter violent extremism (CVE videos) is widely discussed. These videos are often described as “counter-narratives,” implying that narrativity is a crucial factor for their effectiveness. Experimental research testing this assumption is rare and direct comparisons of narrativity effects between propaganda and CVE videos are lacking. To fill this gap, we conducted two experiments (one in a laboratory and one online) in which we confronted German participants with different religious affiliations and from various cultural backgrounds (NStudy 1 = 338 and NStudy 2 = 155) with Islamist extremist or right-wing extremist propaganda videos and with corresponding CVE videos. The results confirmed that narrativity (a) increases persuasive processing of propaganda and CVE videos, (b) fosters amplification intentions regarding these videos, and (c) increases attraction to extremists versus counter-activists. Thus, our studies highlight the crucial role of narrativity in both extremist propaganda and video-based CVE approaches.

                                                        The gaming ecosystem is increasingly observed with the concern that it could pose a threat to public safety, and research accumulates evidence for blatant extremism in the surrounding online space of games. Currently, a connection between gaming and extremism can be established through identity related processes, e.g., gaming-related radicalization elements, distal to gaming itself, such as gaming communities and culture. However, this also raises the question of what the precise function of proximal gaming factors, such as gameplay, mechanics, stories, or game-play motivations, is in the relationship between gaming and extremism. This article aims to shed light on the relation of gaming and extremism by identifying individual profiles of videogame playing based on gameplay motivations and linking them to indications of radical attitudes (here: xenophobia and violence acceptance) as well as conspiracy beliefs that can be associated with extremist beliefs. Further, we include marginalization and anomie as mediators to gain comparative and fine-grained information about the sole impact of gaming motives on radical attitudes. Our findings indicate that while few motivational profiles exhibit weak yet direct connections to radical attitudes, others display the opposite pattern, suggesting a more complex relationship. Marginalization and anomie strongly predict most radical outcome variables and mediate the relationship in most cases, however sometimes negatively. We only found one complex motivational profile that substantially leans toward late-stage radical attitudes, while for instance, dominant social motives clearly inhibit radical outcomes. The current study thus deflates any straightforward perspective on the becoming of a ‘radical gamer’.

                                    From solidarity to blame game: A computational approach to comparing far-right and general public Twitter discourse in the aftermath of the Hanau terror attack

                                                        Terror attacks are followed by public shock and disorientation. Previous research has found that people use social media to collectively negotiate responses, interpretations, and sense-making in the aftermath of terror attacks. However, the role of ideologically motivated discussions and their relevance to the overall discourse have not been studied. This paper ad-dresses this gap and focuses specifically on the far-right discourse, comparing it to the general public Twitter discourse following the terror attack in Hanau in 2020. A multi-method ap-proach combines network analysis and structural topic modelling to analyse 237,000 tweets. We find responsibility attribution to be one of the central themes: The general discourse pri-marily voiced sympathy with the victims and attributed responsibility for the attack to far-right terror or activism. In contrast, the far right – in an attempt to reshape the general narra-tive – raised a plethora of arguments to shift the attribution of responsibility from far-right activism towards the (political) elite and the personal circumstances of the shooter. In terms of information sharing and seeking, we demonstrate that new information was contextualised differentially depending on the ideological stance. The results are situated in the scientific dis-course concerning differences in social media communication ensuing terrorist attacks.

                                                        Confrontation with radical online content has been empirically linked to the facilitation of radicalization processes. Therefore, building a presence of information about potential prevention of radicalization through an online campaign may be particularly relevant to limit the activities and appeals of radical actors. In this study, we thus examine the effectiveness of campaign material focused on cognitive biases (i.e., when people’s cognitive processes of information are systematically distorted). We test the success of the campaign material with respect to three campaign objectives: Building (1) knowledge about biases, (2) confidence to recognize biases, and (3) awareness and relevance of the issue. We conducted an online-experiment with adolescents (N = 223) comparing a control group (no exposure to the campaign material) to (A) a group that watched the developed campaign videos and (B) a group that watched the videos and took a self-assessment quiz. This comparison aims at testing how different levels of interactivity affect the three campaign objectives. The results suggest that the campaign materials increased knowledge about cognitive biases, but did not affect adolescents’ confidence in recognizing biases and the perceived relevance of learning about biases.
