There yet another study on intelligence that surely has it nailed down this time.

Surely. Study gives more proof that intelligence is largely inherited – talks about intelligence being determined by the volume of the white matter, and therefore having a high genetic correlation (Let’s not even get into correlation v causation, much less figuring out what the hell intelligence is.) Of course the punchline here is that studies show that women have more white matter than men, so we must just be genetically smarter, right? Except maybe we’re smarter by brain volume than men because we have more grey matter. Confused? That’s brain imaging studies for you. Then again, maybe volume of white v grey only account for a few kinds of intelligence, and we should just stick with good ol’ phrenology for the rest.
