This article examines conspiracy beliefs in education using a mixed-methods design that combines international comparisons, verbal evocations, and interviews. The quantitative survey includes 1,118 preservice teachers in England, Greece, and France. Results show higher levels in Greece, intermediate levels in England, and lower levels in France, alongside stronger perceived rationality in France. Part 2 focuses on French participants and examines social representations of the “conspiracist student” through a free-evocation task. Correspondence analysis reveals two major axes (critical rationality vs disqualification/ignorance and institutional trust vs suspicion/manipulation). Part 3 draws on 19 interviews with in-service teachers in France. Teachers report infrequent yet destabilizing episodes, distrust toward institutions, and tensions with the classroom framework. They mobilize media and information literacy practices but note constraints related to time, training, and legitimacy. We discuss implications for initial and continuing teacher education to prevent the spread of conspiracy beliefs in schools.

In an increasingly globalized world challenged by multiple social problems, global social identifications (GSIs, e.g., with all humanity) are concepts of growing interest. Although such identifications can be affected by the cultural contexts in which they are manifested, research on them remains largely confined to Western, Educated, Industrialized, Rich, Democratic (WEIRD) societies. Using data collected in 45 countries (N = 9807, preregistered), we compared the strength of three types of GSIs between countries and cultural clusters, and explored the possible role of five cultural dimensions. The results revealed relatively small cross-national differences in GSIs overall, but African and South-East Asian cultural clusters reported significantly stronger identifications than those from other regions, with India, South Africa, and Ghana scoring the highest. Contrary to our hypotheses, GSIs were positively associated with in-group collectivism, survival values, and traditional values, while institutional collectivism was unrelated. As expected, humane orientation was positively related to most GSIs. Additional exploratory analyses showed higher GSIs in countries with a lower quality of life (broadly understood). GSIs were also more pronounced in less globalized, younger societies, with a higher proportion of men, fewer immigrants, and stronger diversity. Our study highlights the need to broaden research on GSIs beyond WEIRD contexts.

Science is integral to society because it can inform individual, government, corporate, and civil society decision-making on issues such as public health, new technologies or climate change. Yet, public distrust and populist sentiment challenge the relationship between science and society. To help researchers analyse the science-society nexus across different geographical and cultural contexts, we undertook a cross-sectional population survey resulting in a dataset of 71,922 participants in 68 countries. The data were collected between November 2022 and August 2023 as part of the global Many Labs study “Trust in Science and Science-Related Populism” (TISP). The questionnaire contained comprehensive measures for individuals’ trust in scientists, science-related populist attitudes, perceptions of the role of science in society, science media use and communication behaviour, attitudes to climate change and support for environmental policies, personality traits, political and religious views and demographic characteristics. Here, we describe the dataset, survey materials and psychometric properties of key variables. We encourage researchers to use this unique dataset for global comparative analyses on public perceptions of science and its role in society and policy-making.

Wind turbines are a focal point of contemporary environmental debates, symbolizing progress in renewable energy but also generating significant social tension. This study introduces FactoShinySR, a web-based application designed to facilitate correspondence factor analysis (Corr.F.A.) for studying social representations, making complex analyses accessible to researchers without advanced programming skills. Using data from 323 participants who completed free association tasks and Likert-scale questionnaires, the tool was applied to examine social representations, attitudes toward wind turbines, and trust in authorities. Corr.F.A. revealed two primary dimensions: ecological versus critical attitudes and systemic optimism versus concrete opposition. Positive representations highlighted environmental benefits, while negative perceptions focused on local impacts, such as noise, visual disruption, and ecological harm. Trust in authorities emerged as a critical factor shaping attitudes. FactoShinySR proved instrumental in visualizing the complex socio-representational structures surrounding wind turbines, offering a platform for analyzing environmental perceptions. By bridging methodological complexity and practical application, this tool enables researchers and practitioners to better understand and address public social representations.

This 68-country survey (n = 71,922) examines science information diets and communication behavior, identifies cross-country differences, and tests how such differences are associated with sociopolitical and economic conditions. We find that social media are the most used sources of science information in most countries, except those with democratic-corporatist media systems where news media tend to be used more widely. People in collectivist societies are less outspoken about science in daily life, whereas lower education is associated with higher outspokenness. Limited access to digital media is correlated with participation in public protests on science matters. We discuss implications for future research, policy, and practice.

Science is crucial for evidence-based decision-making. Public trust in scientists can help decision makers act on the basis of the best available evidence, especially during crises. However, in recent years the epistemic authority of science has been challenged, causing concerns about low public trust in scientists. We interrogated these concerns with a preregistered 68-country survey of 71,922 respondents and found that in most countries, most people trust scientists and agree that scientists should engage more in society and policymaking. We found variations between and within countries, which we explain with individual- and country-level variables, including political orientation. While there is no widespread lack of trust in scientists, we cannot discount the concern that lack of trust in scientists by even a small minority may affect considerations of scientific evidence in policymaking. These findings have implications for scientists and policymakers seeking to maintain and increase trust in scientists.

Conspiracy beliefs have been linked to perceptions of collective victimhood. We adopt an individual perspective on victimhood by investigating the relationship between conspiracy beliefs and the individual disposition to perceive and react to injustice as a victim, i.e., victim justice sensitivity (VJS). Data from two German samples (Ns = 370, 373) indicated a positive association between VJS and conspiracy mentality beyond conceptually related covariates (e.g., mistrust). In a multinational sample from 15 countries (N = 14,978), VJS was positively associated with both general and specific conspiracy beliefs (about vaccines and climate change) within countries, though these associations varied across countries. However, economic, sociopolitical and cultural country-level factors that might explain the cross-country variability (e.g., GDP, Human Freedom Index, individualism-collectivism), including indices of collective exposure to direct violence, did not moderate the studied associations. Future research should investigate the relationship between victimhood and conspiracy beliefs, considering both intraindividual and intergroup perspectives.

Despite the proven effectiveness of COVID-19 preventive measures (social distancing, frequent hand washing, vaccination, etc.), these remain inoperative if individuals do not adopt them. In this research, we sought to investigate the effectiveness of a novel type of intervention to foster compliance with COVID-19 preventive measures. Drawing upon the model of action phases and recent evidence linking social motives to compliance with recommendations from health authorities, we extended implementation intentions to the realm of social goals (Social Goals Implementation Intentions, or SGII). In a first study in France (N = 161), we show that a brief writing task requiring participants to implement a future hypothetical encounter with a close one at risk for severe symptoms of COVID-19 increased compliance intentions by 6.38% 95%CI[1.56, 11.24], d = .42, relative to a deliberation-only control condition. No moderating role of conspiracy beliefs and mentality was found in exploratory analyses. These results were exactly replicated in a pre-registered study conducted among US participants (N = 223), where the increase caused by SGII was 7.18% 95%CI[2.10, 12.27], d = .40. Vaccine intentions were not affected in both countries. Taken together, our results suggest that SGII is a viable theoretical mechanism to design and implement health behavior change interventions. Generating a sense of ‘skin in the game’ may be more effective to bypass irrational beliefs and foster greater adherence to evidence-based health recommendations.

Climate change is currently one of humanity’s greatest threats. To help scholars understand the psychology of climate change, we conducted an online quasi-experimental survey on 59,508 participants from 63 countries (collected between July 2022 and July 2023). In a between-subjects design, we tested 11 interventions designed to promote climate change mitigation across four outcomes: climate change belief, support for climate policies, willingness to share information on social media, and performance on an effortful pro-environmental behavioural task. Participants also reported their demographic information (e.g., age, gender) and several other independent variables (e.g., political orientation, perceptions about the scientific consensus). In the no-intervention control group, we also measured important additional variables, such as environmentalist identity and trust in climate science. We report the collaboration procedure, study design, raw and cleaned data, all survey materials, relevant analysis scripts, and data visualisations. This dataset can be used to further the understanding of psychological, demographic, and national-level factors related to individual-level climate action and how these differ across countries.

Research over the past decade has shown that endorsement of conspiracy theories (CTs) is shaped by motivated cognition processes. Accordingly, CTs are theorized to stem from compensatory processes, as individuals attempt to cope with existential threats (i.e., uncertainty, loss of control). Based on the meaning maintenance model, we investigated whether this compensatory effect could follow from epistemic threats in domains unrelated to CTs in the form of uncanniness. Feelings of uncanniness were experimentally manipulated through exposure to absurdist art and literature in a set of five studies, followed by a mini meta-analysis (Ntotal  = 1,041). We conducted a final, preregistered sixth study (N = 266) manipulating uncanniness through autobiographical recall. No robust evidence for a compensatory effect was found. We discussed methodological and conceptual limitations of the meaning maintenance model, as well as boundary conditions under which conspiracy theories could have a compensatory function to deal with threats.

Effectively reducing climate change requires marked, global behavior change. However, it is unclear which strategies are most likely to motivate people to change their climate beliefs and behaviors. Here, we tested 11 expert-crowdsourced interventions on four climate mitigation outcomes: beliefs, policy support, information sharing intention, and an effortful tree-planting behavioral task. Across 59,440 participants from 63 countries, the interventions' effectiveness was small, largely limited to nonclimate skeptics, and differed across outcomes: Beliefs were strengthened mostly by decreasing psychological distance (by 2.3%), policy support by writing a letter to a future-generation member (2.6%), information sharing by negative emotion induction (12.1%), and no intervention increased the more effortful behavior-several interventions even reduced tree planting. Last, the effects of each intervention differed depending on people's initial climate beliefs. These findings suggest that the impact of behavioral climate interventions varies across audiences and target behaviors.

Conspiracy beliefs are prevalent among members of disadvantaged groups. Adopting a social identity perspective, we hypothesized that these beliefs would reduce the endorsement of internal attributions for inequalities that could negatively affect the image of disadvantaged ingroups. In Study 1 ( n = 1,104), conspiracy mentality was negatively associated with meritocracy beliefs, which attribute success and failure to internal factors. In Studies 2 to 5 ( ns = 179, 251, 221, 248), taking the perspective of a person exhibiting a high (vs. low) conspiracy mentality in a fictitious context reduced participants’ meritocracy beliefs, internal attributions for a privileged outgroup’s situation, and fostered negative attitudes toward the outgroup. However, it did not reduce internal attributions for the situation of a disadvantaged ingroup, nor did it improve attitudes toward the ingroup. Regarding intergroup comparison, conspiracy mentality seems to primarily deteriorate the perception of privileged outgroups rather than improve the perception of disadvantaged ingroups.

(1) Background: This study investigates the influence of social networks on young adults, focusing on both positive and negative impacts. It considers problematic social networking site use (PSNSU), emotional intelligence, empathy, and the phenomenon of Fear of Missing Out (FoMO). (2) Methods: A comprehensive online survey was conducted with 442 participants aged 18 to 30 years that used various psychometric tools to assess emotional intelligence, empathy, internet and social media use, and FoMO. (3) Results: The study revealed that young adults display low competencies in emotional intelligence and empathy, with a tendency towards problematic internet and social media use. High FoMO scores were observed, correlating with negative internet use outcomes. Gender differences in these aspects were also explored. (4) Conclusions: The findings suggest a complex interaction between social network use, emotional skills, and FoMO that impacts young adults’ mental health and social behaviors. This study highlights the need for a nuanced understanding of these relationships and their implications for well-being and social interaction in the digital age.
