This is just further proof of Christianity that children are born drenched in sin. It's not surprising to us Christians, but I bet the atheists are dumbfounded.
Not really, Skeptic. Rather it shows that the are vulnerable to believe in invisible beings and alter their behaviour while 'being watched'. What the children in the experiment did was not evil - so far I have heard evil described, or even sinful - they just did the job the easiest was when they thought no one was watching.
What it does show is that children as liable to accept invisible beings as real and that explains why churches want to run schools for young children as they are easier to convert that older children and adults who can think things through. It means that young children should be protected from claims of invisible beings until such time that such claims can be evaluated by them in an adult manner though I can imagine religions would be happy with that!
