Race gaps in brain size in the very young -- figures here given the basic pattern but there's a lot more evidence. http://emilkirkegaard.dk/en/?p=7121 pic.twitter.com/Ea0R037Bri

Any late gap would still be constrained rather tightly by data on entrance exams, grades, representation, etc. ~3-4 points max seems plausible. Certainly, subscale weights matter. Beyond IQ, differences in social and communication functions etc. shape outcomes, but tangential.
Another option is that spatial ability matters more than we think. It is currently not measured much, guess why. :p

Have often pondered that omission; granted, partly loads on e.g. SAT-M. But confused by discussion of no correlation w/ cranial volumetric data. If there were indeed sufficient correlation, could explain nature of volumetric discrepancy by sex. Presumably used for something.
