Is there a correlation between atheism and intelligence?

[Esquilax]

Theists can be intelligent and introspective with a vital mind. They probably won't be the ones who come to a site like this to fish for souls to save. Not every theist is doctrinaire in regard to ever subject or question any more than they have to be a literalist fundamentalist.

That's what I'm saying: the more outwardly, obviously intelligent a theist is, the less likely they'll be to accept their specific holy book's claims of being the only possible answer ever, ever as gospel.

So I guess it's not religion that's correlated with a lack of intelligence, it's fundamentalism.
