Religious upbringing associated with less altruism, study finds
University of Chicago

Many families believe religion plays an essential role in childhood moral development. But children of religious parents may not be as altruistic as those parents think, according to a new international study from the University of Chicago published Nov. 5 in Current Biology.

A team of developmental psychologists led by Prof. Jean Decety examined the perceptions and behavior of children in six countries. The study assessed the children's tendency to share--a measure of their altruism--and their inclination to judge and punish others for bad behavior.

Children from religious families were less likely to share with others than were children from non-religious families. A religious upbringing also was associated with more punitive tendencies in response to anti-social behavior.

The results were at odds with the perceptions of religious parents, who were more likely than non-religious parents to report that their children had a high degree of empathy and sensitivity to the plight of others.

Consistent with previous studies, in general the children were more likely to share as they got older. But children from households identifying as Christian and Muslim were significantly less likely than children from non-religious households to share their stickers. The negative relation between religiosity and altruism grew stronger with age; children with a longer experience of religion in the household were the least likely to share.

Children from religious households favored stronger punishments for anti-social behavior and judged such behavior more harshly than non-religious children. These results support previous studies of adults, which have found religiousness is linked with punitive attitudes toward interpersonal offenses.

"Together, these results reveal the similarity across countries in how religion negatively influences children's altruism. They challenge the view that religiosity facilitates prosocial behavior, and call into question whether religion is vital for moral development--suggesting the secularization of moral discourse does not reduce human kindness. In fact, it does just the opposite," Decety said.
