We demonstrate that moral reasoning plays ail important role ill group discussions Of moral issues. Groups of three children (11 or 13 years old) played dictator and ultimatum games in the role of proposer with another group of three children. Before group discussion, individual preferences were measured. In both games, there was no difference in individual offers between the two age groups. Analyses of group decision-making processes showed ail age difference in the dictator game. The results indicate that in the 11-year-old groups, individuals making altruistic offers were much less influential than individuals making egoistic offers. Altruists could not defend their arguments even when they were in a majority position. We further found that the level of moral reasoning was higher in the older age group. All results were congruent with the hypothesis that more advanced moral reasoning is associated with defending prosocial arguments against egoistic arguments that are rational in terms of profit maximization.
