A weight of studies over the years have found a negative correlation between intelligence and religiosity. But if that's the case, then why is it so? A new theory proposes that the reason more intelligent people tend to be less religious is because (1) religiosity is rooted in instinct, and (2) more intelligent people are able to overcome their instinctual religiosity relatively more often than less intelligent people.

What do you make of the theory?
At the risk of pointing out the obvious: Just because there is a well established negative correlation between intelligence and religiosity does not mean that all religious people are dumb and all non-religious people are smart, or that all religious people are dumber than all non-religious people. Second, the focus of this discussion should be the notions that (1) religiosity is instinctual and (2) relatively high intelligence allows people to more readily overcome instincts. If you wish to discuss the negative correlation between religiosity and intelligence, get your own thread.
