There is a site of the above name maintained by Englishman Vexen Crabtree, who says he is a Satanist. He has slender academic qualifications but he seems to have read widely. Curiously enough, however, he seems dismissive of religion generally. Only the small band of Satanists have the truth, apparently.
As an atheist myself I find his Satanism amusing but I was interested to see what he has up about religion and IQ. It is commonly asserted that religious people are a bit dim and he accepts that uncritically. The only actual evidence he quotes, however is as follows:
[Paul Bell in Mensa Magazine, 2002, reviewed all studies taken of religion and IQ. He concluded:]
"Of 43 studies carried out since 1927 on the relationship between religious belief and one's intelligence and/or educational level, all but four found an inverse connection. That is, the higher one's intelligence or education level, the less one is likely to be religious or hold "beliefs" of any kind."
As I have pointed out previously, however, such studies are usually poorly sampled and usually report only slight effects. Religious people are less frequent among high IQ people but not by much. And the whole effect could be artifactual: High IQ people get on better within higher education so almost certainly get more of it. But universities are places where religion is skeptically viewed so high IQ people will get more exposure to anti-religious messages. And greater exposure to anti-religious messages would be very likely to undermine religious belief to some extent. So it could be that the level of university exposure accounts wholly for the slightly smaller number of religious people in a high IQ population.
That could be tested fairly easily by assessing religion and IQ BEFORE the people got into university.
In short, I doubt that IQ has any influence on whether you are religious or not. It is probably a surprise to most of my fellow atheists but religious people think THEY are stupid. You have to be pretty dim to think creation was a spontaneous, uncaused event, according to religious people.
There is what I think is good evidence for no association between religion and IQ here
