Since its inception, the concept of neurodiversity has been defined in a number of different ways, which can cause confusion among those hoping to educate themselves about the topic. Learning about neurodiversity can also be challenging because there is a lack of well-curated, appropriately contextualized information on the topic. To address such b...

In this commentary, we examine the implications of the failed replication reported by Vaidis et al., which represents the largest multilab attempt to replicate the induced-compliance paradigm in cognitive-dissonance theory. We respond to commentaries on this study and discuss potential explanations for the null findings, including issues with the p...

Public trust in scientists may be essential for widespread acceptance of science-based solutions to societal problems, including climate change. Across 68 countries (N = 69,534), individuals expressed less trust in climate scientists than scientists in general. In most countries and overall, conservative political orientation was more strongly asso...

We examined data from 59,508 participants across 63 countries to construct a measure of climate policy support and document associations with political orientation across the resulting scale. Preregistered analyses identified a three-factor model capturing support for tax-based, nature protection, and green transition policies. The scale demonstrat...

Ideal partner preferences (i.e., ratings of the desirability of attributes like attractiveness or intelligence) are the source of numerous foundational findings in the interdisciplinary literature on human mating. Recently, research on the predictive validity of ideal partner preference matching (i.e., Do people positively evaluate partners who mat...

According to the justified true belief (JTB) account of knowledge, people can truly know something only if they have a belief that is both justified and true (i.e., knowledge is JTB). This account was challenged by Gettier, who argued that JTB does not explain knowledge attributions in certain situations, later called “Gettier-type cases,” wherein...

Though people usually imagine the typical person as a man rather than a woman, the effect is mixed for racial groups and understudied among traditionally male social groups (e.g., police and criminals) and non-U.S. populations. Results from a survey (N > 5000) collected via a globally distributed laboratory network in over 40 regions demonstrated t...

The Reading the Mind in the Eyes Test (RMET) is widely used in clinical and non-clinical research. However, there is little research rigorously examining the structural properties of RMET scores. We analysed the structural properties of RMET scores in nine existing datasets comprising non-clinical samples ranging from 558 to 9,267 (median = 1,112)...

Cognitive dissonance, a fundamental psychological process involving inconsistent cognitions causing discomfort, may vary across cultures. These variations could be attributed to differences in the way people define themselves, known as “self-construal”. Previous cross-cultural studies on the role of self-construal in cognitive dissonance have mainl...

Cultural logic is a set of cultural scripts and patterns organized around a central theme. The cultural logics of dignity, honor, and face describe different ways of evaluating a person’s worth and maintaining cooperation. These cultural logics vary in prevalence across cultures. In this study, we collaboratively develop and validate a measure capt...

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 chan...

In psychological science, replicability—repeating a study with a new sample achieving consistent results (Parsons et al., 2022)—is critical for affirming the validity of scientific findings. Despite its importance, replication efforts are few and far between in psychological science with many attempts failing to corroborate past findings. This scar...

Since its inception, the concept of neurodiversity has been variably defined and widely discussed, which may cause confusion among those unfamiliar with the topic. Further, learning about neurodiversity is challenging given the lack of well-curated, appropriately contextualized information and the prevalence of misinformation on the topic. To addre...

Surveys are regularly used to estimate the prevalence of belief in conspiracy theories and test hypotheses about causes and consequences of these beliefs. In such research, it is typically assumed that belief reports are sincere. However, evidence for sincerity is rarely provided. In the present study we examine the issue of participant sincerity i...

Awards can propel academic careers. They also reflect the culture and values of the scientific community. But do awards incentivize greater transparency, inclusivity, and openness in science? Our cross-disciplinary survey of 222 awards for the “best” journal articles across all 27 SCImago subject areas revealed that journals and learned societies a...

Recently, research on the predictive validity of ideal partner preference-matching (i.e., do people positively evaluate partners who match...

Mindfulness witnessed a substantial popularity surge in the past decade, especially as digitally self-administered interventions became available at relatively low costs. Yet, it is uncertain whether they effectively help reduce stress. In a preregistered (OSF https://doi.org/10.17605/OSF.IO/UF4JZ; retrospective registration at ClinicalTrials.gov N...

Biases in favor of culturally prevalent social ingroups are ubiquitous, but random assignment to arbitrary experimentally created social groups is also sufficient to create ingroup biases (i.e., the minimal group effect; MGE). The extent to which ingroup bias arises from specific social contexts versus more general psychological tendencies remains...

We argue that proxy failure contributes to poor measurement practices in psychological science and that a tradeoff exists between the legibility and fidelity of proxies whereby increasing legibility can result in decreased fidelity.

In psychological science, replicability—repeating a study with a new sampleachieving consistent results (Parsons et al., 2022)—is critical for affirming the validity of scientific findings. Despite its importance, replication efforts are few and far between in psychological science with many attempts failing to corroborate past findings. This scarc...

There is considerable uncertainty about how thinking style relates to religious belief. In the present study, we tested three hypotheses about relationships between reflective thinking, intuitive thinking (both measured using the Cognitive Reflection Test; CRT) and belief in God or gods (BiG) across 19 culturally and geographically diverse countrie...

Scientific information is crucial for evidence-based decision-making. Public trust in science can help decision-makers act based on the best available evidence, especially during crises such as climate change or the COVID-19 pandemic 1,2. However, in recent years the epistemic authority of science has been challenged, causing concerns about low pub...

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 a...

Religion is a cross-cultural human universal, yet explicit markers of religiosity have rapidly waned in large parts of the world in recent decades. In this paper, we explore whether intuitive religious influence lingers, even among nonbelievers in largely secular societies. We adapted a classic experimental philosophy task to test for lingering pro...

Almaatouq et al. propose a novel integrative approach to experiments. We provide three examples of how unaddressed measurement issues threaten the feasibility of the approach and its promise of promoting commensurability and knowledge integration.

Science is integral to society because it can inform individual, government, corporate, and civil society decision-making on issues such as climate change. Yet, public distrust and populist sentiment may challenge the relationship between science and society. To help researchers analyse the science society nexus across different cultural contexts,...

According to cognitive-dissonance theory, performing counterattitudinal behavior produces a state of dissonance that people are motivated to resolve, usually by changing their attitude to be in line with their behavior. One of the most popular experimental paradigms used to produce such attitude change is the induced-compliance paradigm. Despite it...

Do people in different societies experience morality differently in everyday life? Using experience sampling methods, we investigate everyday moral experiences in a sample from 20 countries across 6 continents, thereby replicating and extending a large-scale study originally conducted in the United States and Canada. We aim to replicate key finding...

Awards can propel academic careers. They also reflect the culture and values of the scientific community. But, do awards incentivise greater transparency, diversity, and openness in science? Our cross-disciplinary survey of 222 awards for the "best" journal articles across all 27 SCImago subject areas revealed that journals and learned societies ad...

Effectively reducing climate change requires dramatic, global behavior change. Yet 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 e...

Report on Australian Cooperative Election Survey 2022 data from the Religion Module.

The spread of misinformation online is a global problem that requires global solutions. To that end, we conducted an experiment in 16 countries across 6 continents (N = 34,286; 676,605 observations) to investigate predictors of susceptibility to misinformation about COVID-19, and interventions to combat the spread of this misinformation. In every c...

There is widespread agreement that delusions in clinical populations and delusion-like beliefs in the general population are, in part, caused by cognitive biases. Much of the evidence comes from two influential tasks: the Beads Task and the Bias Against Disconfirmatory Evidence Task. However, research using these tasks has been hampered by conceptu...

Mental simulation theories of language comprehension propose that people automatically create mental representations of objects mentioned in sentences. Mental representation is often measured with the sentence-picture verification task, wherein participants first read a sentence that implies the object property (i.e., shape and orientation). Partic...

This large, international dataset contains survey responses from N = 12,570 students from 100 universities in 35 countries, collected in 21 languages. We measured anxieties (statistics, mathematics, test, trait, social interaction, performance, creativity, intolerance of uncertainty, and fear of negative evaluation), self-efficacy, persistence, and...

For a single species, human kinship organization is both remarkably diverse and strikingly organized. Kinship terminology is the structured vocabulary used to classify, refer to, and address relatives and family. Diversity in kinship terminology has been analyzed by anthropologists for over 150 years, although recurrent patterning across cultures r...

In recent years, the scientific community has called for improvements in the credibility, robustness and reproducibility of research, characterized by increased interest and promotion of open and transparent research practices. While progress has been positive, there is a lack of consideration about how this approach can be embedded into undergradu...

The COVID-19 pandemic has affected all domains of human life, including the economic and social fabric of societies. One of the central strategies for managing public health throughout the pandemic has been through persuasive messaging and collective behaviour change. To help scholars better understand the social and moral psychology behind public...

Over the past decade, self-administered mindfulness interventions, such as those administered via phone apps, have become increasingly popular. However, their effectiveness for regulating stress is unclear. In a multi-site study (Nsites = 37, Nparticipants = 2,239; all fluent English speakers) we experimentally investigated the efficacy of four sin...

In response to the COVID-19 pandemic, the Psychological Science Accelerator coordinated three large-scale psychological studies to examine the effects of loss-gain framing, cognitive reappraisals, and autonomy framing manipulations on behavioral intentions and affective measures. The data collected (April to October 2020) included specific measures...

How well can social scientists predict societal change, and what processes underlie their predictions? To answer these questions, we ran two forecasting tournaments testing the accuracy of predictions of societal change in domains commonly studied in the social sciences: ideological preferences, political polarization, life satisfaction, sentiment...

All over the world, people reason dualistically. We consider it more probable that mental states, such as love, continue after biological death than we think bodily states, such as hunger, will continue. However the extent to which culture affects mind-body dualism remains unclear. Here, we draw on a large and diverse cross-cultural sample (24 coun...

Ideal partner preferences (i.e., ratings of the desirability of attributes like attractiveness or intelligence) are the source of numerous foundational findings in the interdisciplinary literature on human mating. Recently, research on the predictive validity of ideal partner preference-matching (i.e., do people positively evaluate partners who mat...

There is considerable debate about whether survey respondents regularly engage in “expressive responding” – professing to believe something that they do not sincerely believe to show support for their in-group or hostility to an out-group. Nonetheless, there is widespread agreement that one study provides compelling evidence for a consequential lev...

The Uto-Aztecan language family is one of the largest language families in the Americas. However, there has been considerable debate about its origin and how it spread. Here we use Bayesian phylogenetic methods to analyze lexical data from 34 Uto-Aztecan varieties and 2 Kiowa-Tanoan languages. We infer the age of Proto-Uto-Aztecan to be around 4,10...

The COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively to the global public. Given that subtle differences in information framing can have meaningful effects on behavior, behavioral science research highlights a pressing question: Is it more effective to frame COVID-19 health messages in t...

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about...

There is considerable debate about how often survey respondents engage in “expressive responding”: professing to believe something that they do not sincerely believe to show support for their in-group. Nonetheless, there is widespread agreement that one particular study provides particularly compelling evidence for expressive responding. In the imm...

The COVID-19 pandemic has illustrated the importance of public support for non-pharmaceutical public health interventions and the perils of rampant spread of misinformed or conspiratorial beliefs. Open-minded epistemic attitudes may be associated with adherence to public health recommendations and protect against holding false beliefs. In a large (...

This initiative examined systematically the extent to which a large set of archival research findings generalizes across contexts. We repeated the key analyses for 29 original strategic management effects in the same context (direct reproduction) as well as in 52 novel time periods and geographies; 45% of the reproductions returned results matching...

The relation between religiosity and well-being is one of the most researched topics in the psychology of religion, yet the directionality and robustness of the effect remains debated. Here, we adopted a many-analysts approach to assess the robustness of this relation based on a new cross-cultural dataset (N = 10, 535 participants from 24 countries...

At the beginning of 2020, COVID-19 became a global problem. Despite all the efforts to emphasize the relevance of preventive measures, not everyone adhered to them. Thus, learning more about the characteristics determining attitudinal and behavioral responses to the pandemic is crucial to improving future interventions. In this study, we applied ma...

The study of moral judgements often centres on moral dilemmas in which options consistent with deontological perspectives (that is, emphasizing rules, individual rights and duties) are in conflict with options consistent with utilitarian judgements (that is, following the greater good based on consequences). Greene et al. (2009) showed that psychol...

Semantic priming has been studied for nearly 50 years across various experimental manipulations and theoretical frameworks. These studies provide insight into the cognitive underpinnings of semantic representations in both healthy and clinical populations; however, they have suffered from several issues including generally low sample sizes and a la...

Significance Communicating in ways that motivate engagement in social distancing remains a critical global public health priority during the COVID-19 pandemic. This study tested motivational qualities of messages about social distancing (those that promoted choice and agency vs. those that were forceful and shaming) in 25,718 people in 89 countries...

The COVID-19 pandemic has affected all domains of human life, including the economic and social fabric of societies. One of the central strategies for managing public health throughout the pandemic has been through persuasive messaging and collective behavior change. To help scholars better understand the social and moral psychology behind public h...

The Many Analysts Religion Project (MARP) follows in a tradition of many analysts projects that have examined how variations in analytic choices can affect results (Silberzahn & Uhlmann, 2015). One of the core strengths of the many analysts approach is that there are no direct incentives for analysis teams to attempt to achieve statistical signific...

In recent years, the scientific community has called for improvements in the credibility, robustness, and reproducibility of research, characterized by higher standards of scientific evidence, increased interest in open practices, and promotion of transparency.
