Nationality dominates gender in decision-making in the Dictator and Prisoner's Dilemma Games

Children cooperate more with in-group members than with out-group members in an iterated face-to-face Prisoner's Dilemma Game

Adults are more likely to cooperate with in-group members than with out-group members in the context of social dilemmas, situations in which self-interest is in conflict with collective interest. This bias has the potential to profoundly shape human cooperation, and therefore it is important to understand when it emerges in development. Here we asked whether 6- to 9-year-old children (N = 146) preferentially cooperate with in-group members in the context of a well-studied social dilemma, the iterated Prisoner's Dilemma Game. We assigned children to minimal groups and paired them with unfamiliar same-age and same-gender peers. Consistent with our predictions, children were more likely to cooperate with in-group members than with out-group members in this minimal group context. This finding adds to the current literature on group bias in children's prosocial behavior by showing that it affects decision making in a context that calls on strategic cooperation. In addition, our analyses revealed an effect of gender, with girls more likely to cooperate than boys regardless of the group membership of their partner. Exploring this gender effect further, we found an interaction between gender and age across condition, with older girls showing less sensitivity to the group membership of their partner than younger girls and with older boys showing more sensitivity to the group membership of the partner than younger boys. Our findings suggest that risky cooperation in the face of social dilemmas is shaped by group bias during childhood, highlighting the potentially deeply rooted ties between cooperation and parochialism in humans.

Think of What Really Matters: Structured Analysis of Personal Criteria can Save Lives

Helping decisions are susceptible to many biases—partly due to the helpers’ spontaneous emotional reactions to the appeal diverting their attention from the need to maximize the impact of their help. Attempts to overcome these biases by prompting deliberative thinking—namely, by asking participants to think deeply—have often been unsuccessful. Here, we propose a way of directing people’s attention to the most important aspects of their decisions, by asking them to rate the extent to which such attributes should be considered. In two experiments involving real-world crises, participants who underwent such structured analysis of their personal criteria were more likely to make decisions that maximized the number of lives saved. Moreover, their decisions were more in line with their personal values. We conclude that this method is a simple, efficient way of improving the quality of helping decisions in life-and-death situations.

Emerging challenges to prisoners vaccination of covid-19: Historical, legal and humanitarian view

This research aims to present a legal history of the prisoners’ treatment in global crises along with presenting an overview of prisoners’ treatment during Covid-19 in view of International Humanitarian Laws. Using the formative research method with a conceptual approach and statute approach, data was gathered from various legal documents related to prisoners’ health laws linked to legal purpose theories. This study further explains the need to treat old age prisoners on a priority basis and to what extent international health organizations are making efforts to establish criteria to vaccinate this societal segment. The international regulatory framework was deeply analyzed to draw conclusions and recommendations along with WHO efforts. It was revealed that there exist adequate laws regarding priority health treatment of the prisoners in crises times but existed an enormous need to highlight and address the sensitive humanitarian issue. Additionally, WHO and other international organizations have also revised the international laws during Covid-19 to treat the prisoners. However, there is an immense need to devise explicit regulations regarding the accessibility of the vaccine to all the groups of society, including prisoners. The provision of a detailed overview of international laws and treaties regarding prisoners’ priority health treatment is a major advance of this research. Further recommendations for the developed and developing nations and future research directions are suggested.
