Psychological interventions against misinformation and ideological bias
Full text linkAs the world faces crises such as the Russian war against Ukraine, climate change, and COVID-19, evidence-based responses are crucial. Yet, the widespread dissemination of false, biased, and manipulative information threatens informed decision-making. This dissertation explores how psychological interventions can counter misinformation and ideological bias. It aims to (1) systematically review existing interventions, (2) highlight the roles of social identity and ideology in motivated reasoning, and (3) test selected interventions in real-world contexts. Study 1 presents a systematic review of 176 research articles on psychological interventions against misinformation. Most studies focused on fact-checking, lacked theoretical integration, and rarely addressed motivated reasoning. Study 2 tested a strategic, text-based inoculation against Russian disinformation. Social identity emerged as a key susceptibility factor in motivated reasoning. The inoculation reduced the perceived credibility of Russian disinformation and even shifted attitudes on the Russian war against Ukraine—regardless of identification strength. Study 3 examined a feedback intervention to reduce ideological bias in interpreting scientific evidence. Feedback significantly reduced ideological bias among both liberals and conservatives. However, adding a social norm nudge had no additional benefit. This dissertation deepens the understanding of the emerging, interdisciplinary research field of interventions against misinformation and ideological bias. It theoretically advances the field by introducing novel concepts and illuminating the roles of social identity and ideology in information processing. Moreover, it emphasizes the need for scalable solutions to strengthen resilience against misinformation and ideological bias at both individual and societal levels
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

No full textJoin me in Death: Managing Mortality Salience via Mediated Social Encounters
No full textThe synopsis of this cumulative dissertation reports the theoretical background, methodology and main results of five studies addressing the role of intergroup versus interpersonal similarities for mediated social encounters under conditions of mortality salience (MS). Drawing upon terror management theory (TMT, Greenberg, Pyszczynski, & Solomon, 1986) individuals were expected to prefer similar over dissimilar others under conditions of MS. In theory, similarity can take place on the intergroup level (i.e. by belonging to the same in-group) as well as on the interpersonal level (e.g., by holding the same attitudes). So far, the relative relevance of intergroup versus interpersonal similarity has not been studied systematically. Particularly in mediated social encounters, intergroup and interpersonal similarity can be independent from each other and might have different effects.
The results of five studies in different contexts confirmed intergroup and interpersonal similarities to have different effects in mediated encounters under conditions of MS. In an online dating context, a similarity-attraction effect emerged only among in-group but not out-group members (Study 1), and intergroup but not interpersonal dissimilarity threatened the individuals’ defense against MS (Study 2). In a gaming context, individuals preferred an interpersonally similar in-group (versus out-group) avatar (Study 4) but showed no in-group bias when the avatar was interpersonally dissimilar (Study 3). Further, the valence of the in-group played a role under conditions of interpersonal dissimilarity (Study 3), but not under conditions of interpersonal similarity (Study 4). Finally, Study 5 found an increased interest in media content by in-group but not out-group members under conditions of MS even when the content (extremist propaganda) was negatively valenced and did not match the recipients’ political attitude. The results are discussed regarding their implications
"Resistance!": Collective Action Cues in Conspiracy Theory-Endorsing Facebook Groups
Full text linkConspiracy theories on social media have been suspected of contributing to mobilization and radicalization. Yet, few studies have examined the prevalence of psychological variables that may serve to motivate normative and non-normative collective action in this material. Drawing from the "social identity model of collective action", the current study uses a mixed-methods approach to examine the prevalence of collective action cues in conspiracy theory-endorsing social media spaces. Towards this end, I examined four German Facebook groups (Covid-19-Skeptic, Far-Right, Chemtrail, and Political Affairs) during the first months of the Covid-19 pandemic. The results of qualitative content analysis (N = 828 posts), a hierarchical cluster analysis, and the examination of popularity cues showed that: (a) collective action cues were frequent; (b) most posts transmitted alternative views (Cluster 1) or absolutist ideologies (Cluster 2) with few collective action cues - yet, more than one-third of the posts were either mobilizing (Cluster 3) or wrathful (Cluster 4), entailing multiple collective action cues including cues theoretically linked to non-normative action; (c) mobilizing and wrathful posts were more engaging than alternative views and absolutist ideologies; (d) the types of posts and levels of engagement varied between the examined groups such that the Chemtrail and the Far-Right group disseminated more content with a higher mobilizing potential. The Far-Right group was also the most active in responding to its members. The results of this study are novel in that they demonstrate the prevalence of cues that have been linked to non-normative collective action in psychological research within conspiracy theory-endorsing Facebook groups
Hate and harm
Full text linkFrom a psychological point of view, hate speech can be conceptualized as harmful intergroup communication. In contrast to other forms of incivility, hate speech is directed toward individuals because of their (perceived) social identity. This explains why the harm of hate speech can extend to entire social groups and societies. Hate speech therefore cannot be separated from pre-existing power structures and resource inequalities, as its harm is particularly severe when coping resources are already deprived. Psychological research on the perpetrators of hate speech links hate speech to a lack of empathy and the acceptance of, or even desire for social inequalities. In summary, hate speech jars the norms of democratic discourses by denying fellow humans basic respect and violating the democratic minimal consent of human equality. Overall, the chapter demonstrates the usefulness of a (social) psychological perspective on the harms of hate speech for both researchers and practitioners
