The Humanist Society of Singapore posted an article in Facebook, quoting from the article the following:
Academics from seven universities across the world studied Christian, Muslim and non-religious children to test the relationship between religion and morality.
They found that religious belief is a negative influence on children’s altruism.
“Overall, our findings … contradict the commonsense and popular assumption that children from religious households are more altruistic and kind towards others.”
I wouldn’t be surprised by the observations of the study. Generally speaking, religious people can become as mean as the “god” that they profess to believe in. If they believe in a punitive god, they are likely to become punitive as well in their own lives.
