The Advantage of Big Team Science
The credibility revolution in psychology and related sciences contributed to the adoption of large-scale research initiatives known as Big Team Science (BTS). BTS has made significant advances in addressing issues of replication, statistical power, and diversity through the use of larger samples and more representative cross-cultural data. However, while these collaborations hold great potential, they also introduce unique challenges related to t…
A megastudy of behavioral interventions to catalyze public, political, and financial climate advocacy
Addressing climate change depends on large-scale system changes, which require public advocacy. Here, we identified and tested 17 expert-crowdsourced theory-informed behavioral interventions designed to promote public, political, and financial advocacy in a large quota-matched sample of US residents (n = 31,324). The most consistently effective intervention emphasized both the collective efficacy and emotional benefits of climate action, increasi…
Invariance
Measurement involves numerous theoretical and empirical steps—ensuring our measures are operating the same in different groups is one step. Measurement invariance occurs when the factor loadings and item intercepts or thresholds of a scale operate similarly for people at the same level of the latent variable in different groups. This is commonly assumed to mean the scale is measuring the same thing in those groups. Here we test the assumption of …

A many-analysts approach to the relation between religiosity and well-being
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). We recruited 120 analysis teams to investigate (1) whether religious people self-report higher well-…
How to understand a research question—a challenging first step in setting up a statistical model
Harnessing dehumanization theory, modern media, and an intervention tournament to reduce support for retributive war crimes
We demonstrate how psychological scientists can curate rich-yet-accessible media to intervene on conflict-escalating attitudes during the earliest stages of violent conflicts. Although wartime atrocities all-too-often ignite destructive cycles of tit-for-tat war crimes, powerful third parties can de-escalate the bloodshed. Therefore, following Russia's illegal invasion of Ukraine, we aimed to reduce Americans' support for committing retributive w…
Retracted Article
Failures to replicate evidence of new discoveries have forced scientists to ask whether this unreliability is due to suboptimal implementation of methods or whether presumptively optimal methods are not, in fact, optimal. This paper reports an investigation by four coordinated laboratories of the prospective replicability of 16 novel experimental findings using rigour-enhancing practices: confirmatory tests, large sample sizes, preregistration an…
Insights into the accuracy of social scientists' forecasts of societal change
Situational factors shape moral judgements in the trolley dilemma in Eastern, Southern and Western countries in a culturally diverse sample
What types of daydreaming predict creativity? Laboratory and experience sampling evidence
Lay Theories of the Wandering Mind
People often fail to keep their mind from wandering. Here, we examine how the tendency to mind wander is affected by people’s beliefs, or lay theories. Building on research on lay theories and self-regulation, we test whether differences in people’s beliefs about the extent to which mind wandering is controllable affect thought control strategies and mind-wandering rates in daily life and the laboratory. We develop a new scale to assess control-r…
Essentially subhuman
Investigates the relationship between psychological essentialism and the tendency to dehumanize members of other social groups
To which world regions does the valence-dominance model of social perception apply
Over the past 10 years, Oosterhof and Todorov’s valence–dominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgements of faces. Because this model has primarily been developed and tested in Western regions, it is unclear whether these findings apply to other regions. We addressed this question by replicating Oosterhof an…
The Psychological Science Accelerator
Concerns about the veracity of psychological research have been growing. Many findings in psychological science are based on studies with insufficient statistical power and nonrepresentative samples, or may otherwise be limited to specific, ungeneralizable settings or populations. Crowdsourced research, a type of large-scale collaboration in which one or more research projects are conducted across multiple lab sites, offers a pragmatic solution t…
Raising IQ among school-aged children
Context Moderates Affirmation Effects on the Ethnic Achievement Gap
We attempted to replicate a self-affirmation intervention that produced a 40% reduction in the academic achievement gap among at-risk students. The intervention was designed as a protection against stereotype threat—, which creates stress and suppresses the performance, engagement, and learning of students stereotyped as intellectually inferior. In previous research, Black and Hispanic students who engaged in a values-affirmation exercise signifi…
