The Altruism Prioritization Engine: How Empathic Concern Shapes Children's Inequity Aversion in the Ultimatum Game

Children are not only concerned about fairness but also care for others. This study examined how experimentally induced empathic concern influences children's responses to inequity, particularly when fairness considerations may conflict with empathy-driven motivations. A sample of 10- to 12-year-old children (N = 111, 62 boys, 49 girls) from China were randomly assigned to an empathic or non-empathic condition and completed multiple rounds of ultimatum and dictator games, acting as recipients and proposers. The results showed that children in the empathic concern condition were more likely to accept disadvantageous offers (F (1, 109) = 10.723, p = 0.001) and reject advantageous offers (F (1, 109) = 11.200, p = 0.001) than those in the non-empathic condition. Furthermore, in the dictator game, children in the empathic condition shared significantly more resources with the same protagonist (F (1, 109) = 110.740, p < 0.001). These findings suggest that empathic concern affects children's inequity aversion and that empathic concern takes priority in guiding children's inequity aversion when it conflicts with the fairness criterion. Moreover, our findings suggest that altruistic motivations potentially play a role in children's responses to their inequity aversion.
