Article
Full-text available
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, w...

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...
Article
Full-text available
Impersonal cooperation among strangers enables societies to create valuable public goods, such as infrastructure, public services, and democracy. Several factors have been proposed to explain variation in impersonal cooperation across societies, referring to institutions (e.g., rule of law), religion (e.g., belief in God as a third-party punisher),...
Article
Full-text available
Corruption is a pervasive phenomenon that affects the quality of institutions, undermines economic growth and exacerbates inequalities around the globe. Here we tested whether perceiving representatives of institutions as corrupt undermines trust and subsequent prosocial behaviour among strangers. We developed an experimental game paradigm modellin...
Article
Full-text available
Cooperation among strangers has been hypothesized to have declined in the United 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 experimenta...
Article
Full-text available
Cooperation underlies the ability of groups to realize collective benefits (e.g., creation of public goods). Yet, cooperation can be difficult to achieve when people face situations with conflicting interests between what is best for individuals versus the collective (i.e., social dilemmas). To address this challenge, groups can implement rules abo...

Article
Full-text available
Natural disasters have threatened human societies throughout history, however, their psychological effects on people are not fully understood. We hypothesized that natural disaster risk and lack of coping capacity are positively related to conspiracy beliefs and tested these relationships across three studies. Study 1 analyzed a global dataset (47,...
Preprint
Research in the social and behavioral sciences is accumulating at an exponential rate. A challenge facing scientists is to use the accumulative research to quantitatively determine which predictors contribute the most to explaining variation in a specific phenomenon. Here, we provide a novel application of machine learning to meta-analyze an entire...
Article
Full-text available
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 in...
Article
Full-text available
Past research hypothesized that men and women differ in their tendency to cooperate with strangers in situations that involve a conflict of interests. However, recent empirical research has provided converging evidence that men and women cooperate to a similar extent, and that differences in cooperation can emerge in response to specific situationa...

Article
Full-text available
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, a...
Article
Full-text available
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 pr...
Article
Full-text available
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 cooper...

The COVID-19 pandemic presents threats, such as severe disease and economic hardship, to people of different ages. These threats can also be experienced asymmetrically across age groups, which could lead to generational differences in behavioral responses to reduce the spread of the disease. We report a survey conducted across 56 societies (N = 58,...

Article
Full-text available
Interpersonal trust is an important source of social and economic development. Over decades, researchers debated the question whether and how public institutions influence interpersonal trust, making this relationship a much-discussed issue for scientific debate. However, experimental and behavioral data and insights on this relationship and the un...
Article
Full-text available
We effortlessly sort people into different racial groups from their visual appearance and implicitly generate racial bias affecting cognition and behaviour. As these mental activities provide the proximate mechanisms for social behaviours, it becomes essential to understand the neural activity underlying differences between own-race and other-race...
Article
Full-text available
Despite menstruation being a physiological phenomenon in women’s life, social research has highlighted that there are still many taboos, also conveyed by advertising, which prevent an open discourse on the topic and can have negative impacts on women’s well-being. The present study examined the influence of the exposure to existing TV advertisement...
Article
Objectives: Interpersonal relationships contribute to the psychological adjustments to chronic disease, directly affecting health and, more generally, life satisfaction of patients. Those factors are often threatened by the fear of becoming target of prejudices and discrimination from those who share their daily life with. Thus, this study propose...
Article
Reconciling individual choices with public interest is central to human society: from market competition to environmental protection, there are many situations that can be modelled by means of social dilemmas. This paper reviews the psychological literature contributions investigating the specific impact of group size on cooperation in social dilem...
Article
Full-text available
Years of research on bystander apathy have demonstrated that the physical presence of others can reduce the tendency to help individuals needing assistance. Recent research on the implicit bystander effect has suggested that simply imagining the presence of others can lead to less helping behavior on a subsequent unrelated task. The present study w...
