Facts:
Richard Haier et al. have a new article forthcoming in Neuroimage reporting that g is partly determined by brain volume and location of gray matter. Well, I never woulda guessed.
Personal Musings:
As a side note, the clipping says the research team is currently evaluating the MRI data to see if there are gender differences in IQ patterns. Anybody want to take a guess on what they’ll find? I’ll put my money on the ticket that says they find females, on average, have more gray matter and score higher, but that the variance is higher in males in both IQ and gray matter. I’ll also take a stab and say that they find a lateralization effect, with females having more gray stuff on the left in the posterior prefrontal area, and males with more gray stuff on the right, probably around the cingulate area–and that this difference is related to verbal-performance IQ differences. Any takers? 😉
