While competition between groups is known to increase cooperation within groups, the precise magnitude of its influence is not clear. Theoretically-relevant moderators that could influence this relationship have been left largely unexplored, and influential methods of studying cooperation and competition have not been assessed. Therefore, in this pre-registered meta-analysis, we investigated the impact of between-group interactions, including outright between-group competition and situations where groups compare their performance to other groups, on within-group cooperation. We conducted a systematic review of the literature involving economic games that compare cooperation in the presence of an intergroup interaction to cooperation within single groups. We compiled 17 relevant studies which yielded 47 effect sizes. Our multilevel random effects model revealed a small-to-medium, positive effect of intergroup interaction on within-group cooperation (g = 0.505, N = 4187). Confirmatory moderator analyses indicated that males, compared to females, invested more in within-group cooperation during intergroup interactions than in single, isolated groups. Additionally, effects involving intergroup comparison were weaker than effects featuring intergroup competition. Exploratory moderator analyses revealed that several variations in the methods of study impact the effect on within-group cooperation (e.g. deception, decision type, and participant matching). Our findings present compelling meta-analytic evidence that intergroup competition has a reliable impact on cooperation, and raises several opportunities for future research.Show less

We hypothesise that by increasing the prominence and clarity of symbols indicating sponsorship disclosure recognition may be increased. Further, we hypothesise that sponsorship disclosures may lead to positive responses in consumers. 300 UK-based participants took part in a randomized online experiment. Participants were presented with one of four sponsorship disclosure symbols on a mock-up website, on which they chose a hotel. Further, recognition of sponsorship disclosures, as well as fairness perceptions and purchase intention, were assessed. Results showed that more prominent and clearer symbols led to increased recognition of sponsorship disclosure. Significant decreases in purchase intention and fairness perceptions were found for disclosing sponsorship to participants after choosing a hotel. We suggest that the obtained insights may be used to refine sponsorship disclosure guidelines.Show less

Costs to prevent climate change can be distributed across different countries to solve this problem. However, what do people think is the fair way to distribute these costs and will they change their mind when they are informed about their country’s allocated costs? The hypothesis in this research is that the higher the wealth and pollution level of a country, the more costs will be distributed towards it. Additionally, it is expected that people who receive explicit information about their country’s wealth or pollution level will distribute less costs towards themselves. In this study the participants had to distribute costs between four country sets based on either wealth or pollution. Some received explicit knowledge about the wealth or pollution level of their country, to see if this influenced their distributive preference. Results showed that people distribute more costs to a country the higher its wealth or pollution level. When informed about their own country’s wealth or pollution level, people from less wealthy sets are willing to contribute more to the climate costs. This shows that people might be willing to pay more than would be expected at first hand.Show less

Doing so requires cooperation, but collectively mitigating the effects of climate change results in a public goods dilemma in which everyone benefits, despite contributing to the costs accompanied. With this, questions regarding fairness on distributing these costs arise. This study adds to the small body of literature on solving public goods dilemmas related to climate change by examining how the six cultural dimensions defined by Hofstede (2001) correlate with the preference to pay more to reduce the effects of climate change. Doing so, the distribution preferences of 3771 participants in 51 countries were measures. The results show that long-term orientation correlates with the preference to pay more, especially for the richest set of countries. Individualism, power distance, masculinity, uncertainty avoidance and indulgence do not significantly correlate to the preference to pay more to reduce the effects of climate change, contradicting previous research on public good dilemmas and pro-environmental behavior. Implications of these findings, alongside limitations of the study and further research directions are discussed.Show less

It is known that people living in poverty feel shame, but what the impact is on trust, for instance when seeking help, is not well studied. We tried to manipulate 120 female participants into feeling either public shame, private shame, and nothing in particular (baseline condition). This was done by letting the participant in the first two conditions do a very difficult math- and language test, next to a confederate who clearly outperformed them. After the manipulation, a Trust Game was done. We expected that feeling shame caused them to score lower on the trust game and thus have less trust in others. Significant differences were found between shame scores of the public shame and the baseline conditions and between the private shame group and the baseline condition. However, no significant differences were found between the trust scores of the three conditions. This is notable because other studies show that beliefs about how one is perceived by others affects trust. This study provides important information on what feelings of shame can be evoked by counselors, and on the impact on clients’ ability to trust others. Future studies could further explore the mechanism behind this relationship, improving the limitations that were encountered in the present study.Show less
