Children who grew up in religious families are less altruistic than those who are up atheist, researchers have found.

They discovered children from religious families were less likely to share with others than were children from non-religious families.

Those from households identifying as Christian and Muslim were significantly less likely than children from non-religious households to share.

Children from households identifying as Christian and Muslim were significantly less likely than children from non-religious households to share their stickers.

'Our findings contradict the common-sense and popular assumption that children from religious households are more altruistic and kind toward others,' said Professor Jean Decety of the university of Chicago, who led the study, which was published in Current Biology.

'In our study, kids from atheist and non-religious families were, in fact, more generous.'

The team of developmental psychologists examined the perceptions and behaviour 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 behaviour.

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.

TESTING ALTRUISM - THE DICTATOR GAME For the altruism task, children participated in a version of the 'Dictator Game,' in which they were given 10 stickers and provided an opportunity to share them with another unseen child. Altruism was measured by the average number of stickers shared. For the moral sensitivity task, children watched short animations in which one character pushes or bumps another, either accidentally or purposefully. After seeing each situation, children were asked about how mean the behaviour was and the amount of punishment the character deserved. Advertisement

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.

The study included 1,170 children between ages 5 and 12, from six countries—Canada, China, Jordan, South Africa, Turkey and the United States.

Parents completed questionnaires about their religious beliefs and practices and perceptions of their children's empathy and sensitivity to justice.

From the questionnaires, three large groupings were established: Christian, Muslim and not religious.

Children from other religious households did not reach a large enough sample size to be included in additional analyses.

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.

Mecca: The study included 1,170 children between ages 5 and 12, from six countries—Canada, China, Jordan, South Africa, Turkey and the United States.

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 favoured stronger punishments for anti-social behaviour and judged such behaviour more harshly than non-religious children.

These results support previous studies of adults, which have found religiousness is linked with punitive attitudes toward interpersonal offences.

'Together, these results reveal the similarity across countries in how religion negatively influences children's altruism.
