To sum up, 1000 children from 6 different countries were asked to help distribute stickers to classmates by an authority figure; religious kids gave an average of 3 stickers away, while non-religious kids gave an average of 4 stickers away. They were also surveyed as to whether and how a person should be punished for intentionally shoving or bumping another person; religious children were less tolerant of the shoving and more supportive of punishments for the shover.
The study shows its bias by declaring that religious kids are more selfish and punitive. Imagine if the findings had been the reverse. We'd have the media trumpeting that religious kids are more likely to try to curry favor with teachers and classmates (i.e., insecure, needy, and obsequious due to thinking there's a supreme being out there who they should please) as well as more tolerant of bullying by others.
Religious people can't win these days. The psychologists really do hate them. As does anyone who would label a kid a "jerk" over a difference of one worthless sticker.
