Neural responses to ingroup and outgroup members' suffering predict individual differences in costly helping

Little is known about the neurobiological mechanisms underlying prosocial decisions and how they are modulated by social factors such as perceived group membership. The present study investigates the neural processes preceding the willingness to engage in costly helping toward ingroup and outgroup members. Soccer fans witnessed a fan of their favorite team (ingroup member) or of a rival team (outgroup member) experience pain. They were subsequently able to choose to help the other by enduring physical pain themselves to reduce the other's pain. Helping the ingroup member was best predicted by anterior insula activation when seeing him suffer and by associated self-reports of empathic concern. In contrast, not helping the outgroup member was best predicted by nucleus accumbens activation and the degree of negative evaluation of the other. We conclude that empathy-related insula activation can motivate costly helping, whereas an antagonistic signal in nucleus accumbens reduces the propensity to help

Belief in a Just World: Consumer Intentions and Behaviors Toward Ethical Products

Although consumers report positive attitudes toward ethical goods, their intentions and behaviors often do not follow suit. Just-world theory highlights the conditions under which consumers are most likely to prefer fair-trade products. This theory proposes that people are motivated to construe the world as a just place where people get what they deserve. In the current research, when people are confronted with high levels of injustice (communicated need is high) and avenues for justice restoration seem uncertain or unavailable, assisting others by supporting fair trade decreases. However, highlighting how injustice can be redressed through purchases enhances fair-trade support under conditions of high need. The effects are moderated by justice sensitivity factors, such as just-world beliefs and whether the product type (indulgence vs. necessity) makes the injustice of consumer privilege salient. The results suggest that communicating high need when requesting consumer prosocial actions can sometimes backfire. Marketers employing high need appeals should heighten perceptions of justice restoration potential and activate fairness-related thoughts through product positioning to encourage fair-trade purchases

Traditional and Health-Related Philanthropy: The Role of Resources and Personality

I study the relationships of resources and personality characteristics to charitable giving, postmortem organ donation, and blood donation in a nationwide sample of persons in households in the Netherlands. I find that specific personality characteristics are related to specific types of giving: agreeableness to blood donation, empathic concern to charitable giving, and prosocial value orientation to postmortem organ donation. I find that giving has a consistently stronger relation to human and social capital than to personality. Human capital increases giving; social capital increases giving only when it is approved by others. Effects of prosocial personality characteristics decline at higher levels of these characteristics. Effects of empathic concern, helpfulness, and social value orientations on generosity are mediated by verbal proficiency and church attendance.

Intermediated Social Preferences: Altruism in an Algorithmic Era

What are the consequences of intermediating moral responsibility through complex organizations or transactions? This paper examines individual decision-making when choices are known to be obfuscated under randomization. It reports the results of a data entry experiment in an online labor market. Individuals enter data, grade another individual’s work, and decide to split a bonus. However, before they report their decision, they are randomized into settings with different degrees of intermediation. The key finding is that less generosity results when graders are told the split might be implemented by a new procurement algorithm. Those whose decisions are averaged or randomly selected among a set of graders are more generous relative to the asocial treatment. These findings relate to “the great transformation” whereby moral mentalities are shaped by modes of (a)social interaction

Justice from an interdisciplinary perspective: the impact of the revolution in Human Sciences on Peace Research and International Relations

Peace and justice have been a preferred couple in theoretical writings - but what do we know about their empirical relationship? Insights from other disciplines suggest that humans are highly sensitive to violations of justice and that justice concerns permeate social relations. Neuroscientists have located the parts of the brain responsible for negative reactions to violation of claims for justice. Evolutionary biologists have identified rules of distribution and retribution not only in early human societies but among other socially living species as well. Psychologists have observed the emergence of a sense of justice in very early childhood, while behavioral economists have identified behavior of average persons in experiments that deviated significantly from the model of the "economic man" and could only be explained by a sense of justice. The chapter summarizes these findings and outlines their implications for peace research. It highlights the ambivalent nature of justice for social relations. Justice concerns can exacerbate conflicts between individuals and groups but justice can also provide standards for arriving at durable peaceful solutions to conflicts. Understanding these ambivalences and their repercussions for international and intrastate relations provides a promising path towards understanding conflict dynamics

THE NAKED EMPEROR: SEEKING A MORE PLAUSIBLE GENETIC BASIS FOR PSYCHOLOGICAL ALTRUISM

The adequacy of currently popular accounts of the genetic basis for psychological altruism, including inclusive fitness (kin selection), reciprocal altruism, sociality, and group selection, is questioned. Problems exist both with the evidence cited as supporting these accounts and with the relevance of the accounts to what is being explained. Based on the empathy-altruism hypothesis, a more plausible account is proposed: generalized parental nurturance. It is suggested that four evolutionary developments combined to provide a genetic basis for psychological altruism. First is the evolution in mammals of parental nurturance. Second is the evolution in humans (and possibly a few other species) of the ability to see others as sentient, intentional agents and, thereby, to recognize other's needs, even subtle ones. Third is the evolution in humans of tender, empathic emotions as an important component of parental nurturance. Fourth is the evolution in humans of cognitive capacities that make it possible to generalize tender, empathic feelings and, thereby, altruism beyond offspring.
