How economic inequality affects prosocial behavior in children across development

Research has linked economically unequal environments to lower prosocial behavior in adults. However, we know little about how inequality affects children's prosociality. Here, 4- to 9-year-old children (N = 128) played a series of games with several puppets where points were awarded. The distribution of points was characterized by either high inequality or low inequality. Children's donation behavior (i.e., the number of stickers they donated to a poor child), resource division behavior (i.e., how they divided extra points among poor and rich puppets), and fairness perceptions (i.e., how fair they perceived the game to be) were measured in response. Although the experimental manipulation of inequality did not affect children's donations, exploratory analyses revealed that higher inequality in children's home suburb was linked to lower donation rates. Furthermore, with age, children distributed points with increasing concern for poorer individuals, and negative judgments of the inequality were linked to distributing resources to poorer individuals. Here we present the first comprehensive analysis of children's prosocial reactions to high and low inequality across development.
