Why do we believe in God? 2m study prays for answer
That is a very interesting study, and will be useful in many ways but it will not change a thing for current believers.
Only a very small minority has the mental capacity to get rid of the long term indoctrination, most of the believers even if they understand and are shown the exact path how religion was formed by men and evolved as a necessity rather than a truth will shake their head and say "I need it and I'll keep it"
Plus anything that takes money from religious organizations for at least something that resembles actual research instead of creating creationism/ID propaganda is okay by me.
