All kids can be a little selfish, but according to a new study, nonreligious children are more generous than their religious peers. The study looked at kids from China, Jordan, South Africa, Turkey, Canada and the U.S.; and compared Christian, Muslim and nonreligious children. All of the kids were put through a series of tests to judge their behavior. First, kids were given stickers and instructions to keep some, and then allocate some to classmates that weren't there. Nonreligious kids gave more than Christian and Muslim kids.
