Not to dwell on the IQ thing, but it is true that IQ measures an aspect of intelligence that would mostly has nothing to do with religious philosophy. I know what the OP was getting at though. As human's get a better grasp of the natural world, there are aspects of religion that get more difficult to reconcile, at least for fundamentalists. Many, if not most people who follow a religion, are not fundamentalists though and have degrees of agnosticism in their personal beliefs that allow for change.

I find these kinds of debates difficult at times because people are often arguing about different things without realizing it. When I think of religion, I tend to define it as spiritual beliefs in general, and not just dogma based organized religion.
