I wouldn't say that religious people have low IQs but I would say that I find them less intelligent than atheists/agnostics/non-believers, because to me, to deny scientific facts is unintelligent. It also seems as though many devout religious people are brought up in circumstances that inhibit their full intelligence potential--people who are poor, people from third world countries, etc. I think this could contribute to the correlation found in this study.
