At first sight it looks like "More religious = Less IQ". Somehow I doubt that. Religion is not one value. Some religions are anti-knowledge (at least for woman and specific minorities). In Western Europe religious schools (Catholic, Protestant etc) are known to teach at a higher level. In my area they are in high demand due to the quality of their education, even for non-religious parents. (The level of "fanatic" religion is not high here).
