Tyranny of the Peer Group
Why is man so susceptible to believing nonsense, or pretending to believe nonsense, just because his peers do? Man is a social animal. In times past, if he expressed deviant views he would be outcast from his group. That meant death. Man thus evolved the ability to suppress common sense in favour of group consensus. The key then to dispelling religious superstition is just to let everyone know there is a sizeable number of people to think it is bunk.
