What do you think?

I just read an answer from someone that said religious belief does not determine ones intelligence. Now obviously this person was of low intelligence as the statement is flawed in principle. But the research does show that your intelligence is a factor in your religious belief or lack thereof. The higher your level of education, and/or the higher your intelligence, the less likely you are to have religious convictions. This is a conclusion made by a large number of surveys including the Gallop Poll and the US Census Bureau. So what say you to this? (believers and non-believers)
