Self-esteem trajectories over three decades predict opposition to social equality in midlife.

Although life trajectories are frequently theorized to explain people's attitudes toward different social groups, few studies have been able to directly assess their importance with suitable data. Addressing this gap and focusing on the development of general and domain-specific self-esteem, we report results from a population-based sample of Norwegians (N = 2,215) followed over 28 years and five time points from adolescence to midlife. Growth curve models demonstrated that irrespective of self-esteem domain, low levels of self-esteem in adolescence as well as a depressed self-esteem development over the next three decades were related to more overall opposition to social equality as well as more opposition to gender equality and immigration in midlife. The results held when controlling for participants' baseline political orientations and other key covariates in adolescence. Our findings indicate that low self-esteem and a lack of positive self-esteem development can be detrimental to harmonious intergroup relations in ever-diversifying societies. We discuss how future psychological interventions aimed at enhancing self-esteem may promote support for a more inclusive society.

Cultural threat perceptions predict violent extremism via need for cognitive closure.

Understanding the psychological processes that drive violent extremism is a pressing global issue. Across six studies, we demonstrate that perceived cultural threats lead to violent extremism because they increase people's need for cognitive closure (NFC). In general population samples (from Denmark, Afghanistan, Pakistan, France, and an international sample) and a sample of former Mujahideen in Afghanistan, single-level and multilevel mediation analyses revealed that NFC mediated the association between perceived cultural threats and violent extremist outcomes. Further, in comparisons between the sample of former Afghan Mujahideen and the general population sample from Afghanistan following the known-group paradigm, the former Mujahideen scored significantly higher on cultural threat, NFC, and violent extremist outcomes. Moreover, the proposed model successfully differentiated former Afghan Mujahideen participants from the general Afghan participants. Next, two preregistered experiments provided causal support for the model. Experimentally manipulating the predictor (cultural threat) in Pakistan led to higher scores on the mediator (NFC) and dependent variables (violent extremist outcomes). Finally, an experiment conducted in France demonstrated the causal effect of the mediator (NFC) on violent extremist outcomes. Two internal meta-analyses using state-of-the-art methods (i.e., meta-analytic structural equation modeling and pooled indirect effects analyses) further demonstrated the robustness of our results across the different extremist outcomes, designs, populations, and settings. Cultural threat perceptions seem to drive violent extremism by eliciting a need for cognitive closure.

Revisiting the Integration Hypothesis: Correlational and Longitudinal Meta-Analyses Demonstrate the Limited Role of Acculturation for Cross-Cultural Adaptation.

When moving to a new country or living in that country as ethnic-minority-group members, individuals have to relate to different cultural spheres. Scholars and practitioners commonly agree that how people acculturate influences their psychological and sociocultural adaptation. Integration (or biculturalism), which involves engagement in both one's heritage culture and the dominant mainstream culture, is considered the most beneficial acculturation strategy. But how robust is the evidence for the role of acculturation in adaptation? Here, we present a reanalysis of a previous meta-analysis of mostly correlational studies (k = 83, N = 23,197) and a new meta-analysis of exclusively longitudinal studies (k = 19, N = 6,791). Results show that the correlational link between acculturation and adaptation is much weaker than previously assumed and that longitudinal evidence is minuscule at best. Our findings suggest that empirical support is still lacking for the most basic premises of acculturation theory.

Does Digital Intergroup Contact Reduce Prejudice? A Meta-Analysis.

With the ubiquity of technology in the modern life, contact between different social groups via different digital means is an everyday reality. Can such a digital intergroup contact reduce prejudice, or does it exacerbate it? In this study, we summarize the present evidence on the links between intergroup digital contact and prejudice in a variety of intergroup contexts. We meta-analyzed experimental and correlational evidence from 88 independent samples (n = 9,385). Digital intergroup contact showed a small but significant effect consistent with prejudice reduction (g = 0.25). Direct digital contact showed larger effect than indirect forms of contact, and contact via computer-mediated communication showed larger effects than contact achieved via other activities such as interacting with nonplayable characters or embodiment. The effects were similar regardless of the type of out-group targeted by prejudice. Overall, meta-analytical results suggest that digital intergroup contact may reduce prejudice.

Finding your roots: Do DNA ancestry tests increase racial (in)tolerance?

While it is often assumed that Deoxyribonucleic acid (DNA) ancestry results illuminate one's true racial or ethnic lineage, the consequence of this inference remains largely unknown. This leaves two conflictual hypotheses largely untested: Do DNA ancestry tests increase racial tolerance or, alternatively, racial intolerance? Two multiwave experiments aimed to test these hypotheses using either real or bogus DNA ancestry results in combination with random assignment and a tightly controlled repeated-measurements experimental design. Bayesian and inferential analyses on both general and student populations of majority-group members in the United States (i.e., White/European Americans) indicated no support for either hypothesis on measures including multiculturalism, essentialism, and outgroup bias, even when moderating factors such as the degree of unexpected ancestry and genetic knowledge were considered. Despite wide societal optimism as well as concern, receiving DNA ancestry results appears not to impact feelings and attitudes about other racial and ethnic groups. Implications for prospective test-takers and education are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Loneliness trajectories over three decades are associated with conspiracist worldviews in midlife.

In the age of misinformation, conspiracy theories can have far-reaching consequences for individuals and society. Social and emotional experiences throughout the life course, such as loneliness, may be associated with a tendency to hold conspiracist worldviews. Here, we present results from a population-based sample of Norwegians followed for almost three decades, from adolescence into midlife (N = 2215). We examine participants' life trajectories of loneliness using latent growth curve modeling. We show that people reporting high levels of loneliness in adolescence, and those who experience increasing loneliness over the life course, are more likely to endorse conspiracy worldviews in midlife.

Selective cultural adoption: The roles of warmth, competence, morality and perceived indispensability in majority-group acculturation.

Psychological research has begun considering the dynamics involved in majority-group acculturation, which is the extent to which cultural majority groups adopt the culture of immigrants and minority groups. However, previous research has predominantly concentrated on reactions to 'immigrants' or 'minority groups' as a homogenous entity, overlooking the nuanced perceptions and varied valuations attributed to different groups. Recognizing the heterogeneity among immigrant and minority groups, the present work investigated the influence of several perceived characteristics of immigrant and minority groups on majority-group members' adoption of their cultures. Specifically, in three pre-registered studies-one correlational (Nparticipants = 201, Ntrials = 2814) and two within-subjects experimental (Nparticipants = 144 and 146, Ntrials = 720 and 730) designs with close to politically representative samples from the U.K. and U.S.  -majority-group members were more willing to adopt immigrant and minority-group cultures that they perceived as warm, competent and moral because these perceptions made immigrants and minority groups seem indispensable to the identity and economy of the mainstream society. Our studies highlight the importance of considering the differentiated acculturation that majority-group members have to various groups within the same national context. We discuss the societal and cultural repercussions of this selective uptake of other cultures.

Individual, intergroup and nation-level influences on belief in conspiracy theories.

Conspiracy theories are part of mainstream public life, with the potential to undermine governments, promote racism, ignite extremism and threaten public health efforts. Psychological research on conspiracy theories is booming, with more than half of the academic articles on the topic published since 2019. In this Review, we synthesize the literature with an eye to understanding the psychological factors that shape willingness to believe conspiracy theories. We begin at the individual level, examining the cognitive, clinical, motivational, personality and developmental factors that predispose people to believe conspiracy theories. Drawing on insights from social and evolutionary psychology, we then review research examining conspiracy theories as an intergroup phenomenon that reflects and reinforces societal fault lines. Finally, we examine how conspiracy theories are shaped by the economic, political, cultural and socio-historical contexts at the national level. This multilevel approach offers a deep and broad insight into conspiracist thinking that increases understanding of the problem and offers potential solutions.

Social media use, social identification and cross-cultural adaptation of international students: A longitudinal examination.

The mobility experience is an important life event for international students, and achieving successful psychological and sociocultural adaptation is crucial for this experience to be positive. Through a three-wave longitudinal study among international students enrolled at universities in Spain, Portugal, and Poland (n = 233), we examined the relationships between social media use, social identification, and (sociocultural and psychological) adaptation across time. Results of cross lagged panel modeling (CLPM) showed that social media contact with home nationals predicted greater identification with this group. Social media contact with host country nationals predicted poorer adaptation. Social media contact with other international students did not show any effects, while identification with this group predicted better adaptation. Our results point to the dynamic nature of the adaptation process, showing that the role of social media use and identification targeted at different social groups may play different roles than was previously found in cross-sectional research.

An interpretation of meta-analytical evidence for the link between collective narcissism and conspiracy theories.

Meta-analytical evidence indicates the robust association between collective narcissism and conspiracy theories is moderated by the content of conspiracy theories. Belief in conspiracies of specific outgroups fits collective narcissistic posture of intergroup hostility but collective narcissism is also bound to other conspiracy theories because it simultaneously comprises a committed belief (that the ingroup is great) and a threatening belief (that the ingroup is unrecognized). This creates compensatory motivations to believe in conspiracy theories that protect the committed belief and to seize on any conspiracy theory as a meaning-making activity. Collective narcissism and conspiracy theories may also co-occur because they serve to coordinate undemocratic leaders and their constituencies. They produce threatening environments that justify coercion, violence and undemocratic governance.

The role of conspiracy beliefs for COVID-19 health responses: A meta-analysis.

While conspiracy theories about COVID-19 are proliferating, their impact on health-related responses during the present pandemic is not yet fully understood. We meta-analyzed correlational and longitudinal evidence from 53 studies (N = 78,625) conducted in 2020 and 2021. Conspiracy beliefs were weakly associated with more reluctance toward prevention measures both cross-sectionally and over time. They explained lower vaccination and social distancing responses but were unrelated to mask wearing and hygiene responses. Conspiracy beliefs showed an increasing association with prevention responses as the pandemic progressed and explained support for alternative treatments lacking scientific bases (e.g., chloroquine treatment, complementary medicine). Despite small and heterogenous effects, at a large scale, conspiracy beliefs are a non-negligible threat to public health.

The Neglected C of Intercultural Relations. Cross-Cultural Adaptation Shapes Sojourner Representations of Locals.

We investigated, by means of the Reverse Correlation Task (RCT), visual representations of the culturally dominating group of local people held by sojourners as a function of their degree of cross-cultural adaptation. In three studies, using three different methods (reduced RCT, full RCT, conceptual replication) with three independent samples of sojourners and seven independent samples of Portuguese and US-American raters, we gathered clear evidence that poor adaptation goes along with more negative representations of locals. This indicates that sojourner adaptation is reflected, at a social-cognitive level, in the valence of outgroup representations.

Belief in COVID-19 Conspiracy Theories Reduces Social Distancing over Time.

BACKGROUND: Conspiracy theories about the origins of COVID-19 are widespread and have even been propagated by highly ranked state officials and politicians in the US. Health authorities have cautioned that such theories, although not questioning the existence of the pandemic, may increase the spread of the virus by reducing people's efforts to socially distance. METHODS: We test this proposition empirically using longitudinal survey data collected at five timepoints during the early outbreak of the virus in the US (N = 403). RESULTS: Multivariate growth curve analyses showed that, although conspiracy beliefs decreased and social distancing increased over time, people holding more conspiracy beliefs at the beginning of the pandemic showed the lowest increase in social distancing. Moreover, cross-lagged analyses demonstrated that people who reported more conspiracy beliefs at any wave tended to report less social distancing at the following wave. CONCLUSIONS: Our findings show that COVID-19 conspiracy theories pose a significant threat to public health as they may reduce adherence to social distancing measures.
