Here's an idea: Since religionists apparently believe that atheists/ non-believers are evil and the cause of much of the world's troubles, wouldn't it be interesting to poll state and federal prisoners, particularly the more hardcore inmates, as to their propensity toward belief, or the lack, in a deity?
What do you think the results would be?
There have been studies about the number of athiests in jail, and the high-end estimate is .1%, but most people think it isn't that high. Some think the number is way higher than that because religious inmates get special privileges-like group meetings and time with a Chaplin to talk about problems. So the thought is people fake religion to get those privileges. I'm not so sure that is true, based on the rather staunch opinions of many athiests I know. But I don't know any in prison, so I could be off base.
