Goddammit. Seriously. It's well-known that all kinds of intelligence are correlated, at least at the lower end. There is such a thing as a benchmark of the brain that gives a one-dimensional result that tells us a something significant about that person. You're just being touchy-feely superstitious (which is way better than the scared-of-different kind of superstitious, but still).

Then I'm sure you'll find it very easy to provide the study that confirms your claims.

You are the first person I've ever heard that called asking for evidence "superstitious". You might want to look up the definition of that word. Goddammit indeed.

Try not to get too touchy-feely in your reply, just give me the studies you are referring to.
