Not a real meritocracy? How conspiracy beliefs reduce perceived distributive justice
The meritocracy principle, along with other distributive justice principles such as equality and need, is fundamental to the healthy functioning of modern societies. However, our understanding of the factors that shape citizens' perceptions of these principles remains limited. We proposed that conspiracy beliefs are negatively related to distributive perceptions and tested these relationships in four studies. Study 1 analyzed a global dataset (90…
Institutions and cooperation: A meta-analysis of structural features in social dilemmas
Identity and Institutions as Foundations of Ingroup Favoritism: An Investigation Across 17 Countries
Ingroup favoritism can represent a challenge for establishing cooperation beyond group boundaries. In a behavioral experiment conducted across 17 societies ( N = 3,236), we tested pre-registered hypotheses forwarded by social identity and material security frameworks to account for ingroup favoritism in trust toward national ingroups. We related individual-level measures of national identification and perception of institutions to trust, trustwor…
Suspicion of institutions: How distrust and conspiracy theories deteriorate social relationships
Many citizens distrust powerful societal institutions, and hold conspiracy theories about them. What are the implications of this suspicion of institutions for people's social relationships? The current paper proposes that institutions have at least two functions to regulate citizens' social relationships: providing people with a sense of safety, and providing models for group norms and values. Suspicion of institutions undermines both of these f…
The Cooperation Databank: Machine-Readable Science Accelerates Research Synthesis
Publishing studies using standardized, machine-readable formats will enable machines to perform meta-analyses on demand. To build a semantically enhanced technology that embodies these functions, we developed the Cooperation Databank (CoDa)—a databank that contains 2,636 studies on human cooperation (1958–2017) conducted in 78 societies involving 356,283 participants. Experts annotated these studies along 312 variables, including the quantitative…
Cross-cultural variation in cooperation: A meta-analysis
783). Thus, we observed that impersonal cooperation occurred in all societies-and to a similar degree across societies-suggesting that prior research may have overemphasized the magnitude of differences between modern societies in impersonal cooperation. We discuss the discrepancy between theory, past empirical research and the meta-analysis, address a limitation of experimental research on cooperation to study culture, and raise possible directi…
Did cooperation among strangers decline in the United States? A cross-temporal meta-analysis of social dilemmas (1956-2017)
Cooperation among strangers has been hypothesized to have declined in theUnited States over the past several decades, an alarming trend that has potential far-reaching societal consequences. To date, most research that supports a decline in cooperation has relied on self-report measures or archival data. Here, we utilize the history of experimental research on cooperation in situations involving conflicting interests (i.e., social dilemmas). We m…
Corrupt third parties undermine trust and prosocial behaviour between people
Cooperation and Trust Across Societies During the Covid-19 Pandemic
Cross-societal differences in cooperation and trust among strangers in the provision of public goods may be key to understanding how societies are managing the COVID-19 pandemic. We report a survey conducted across 41 societies between March and May 2020 ( N = 34,526), and test pre-registered hypotheses about how cross-societal differences in cooperation and trust relate to prosocial COVID-19 responses (e.g., social distancing), stringency of pol…
Self-Interest Bias in the Covid-19 Pandemic: A Cross-Cultural Comparison between the United States and China
In the global crisis of the COVID-19 pandemic, many countries attempt to enforce new social norms to prevent the further spread of the coronavirus. A key to the success of these measures is the individual adherence to norms that are collectively beneficial to contain the spread of the pandemic. However, individuals’ self-interest bias (i.e., the prevalent tendency to license own but not others’ self-serving acts or norm violations) can pose a cha…
Personality and prosocial behavior: A theoretical framework and meta-analysis
Decades of research document individual differences in prosocial behavior using controlled experiments that model social interactions in situations of interdependence.However, theoretical and empirical integration of the vast literature on the predictive validity of personality traits to account for these individual differences is missing.Here, we present a theoretical framework that identifies 4 broad situational affordances across interdependen…
