That would not make sense at all.
IQ more than anything else (at least fluid IQ) is a test of raw, pure, brain speed and efficiency. Studies have found that as IQ rises, the brain works more efficiently.
If you have spent time around bright people, one of the most striking things about them is how lightning fast they are. This can be seen even in conversation. Have you ever met people so fast that they almost finish your sentences for you. You get halfway through the sentence, and they are already reacting to the sentence because they have actually predicted what the rest of the sentence is! That’s pretty damn smart.
Some very bright people have fast moving eyes. If you watch them when they talk, you see their eyes flitting all around very rapidly. Sometimes there are also a lot of micromovements with their faces.
In fact, I think I can see this even comparing a 110–115 IQ person to a 95–100 IQ person (I am guessing at their IQ’s). The latter are noticeably slower, and the former are often strikingly fast. The slower people are often very nice and pleasant, but they’re just not as fast. You have to admit it.
