Racial brain volume values of JP Rushton are averages of 43 sources of racial differential brain size data. The edges of the three circles represent the average brains of the three races. Each brain is a sphere of equivalent volume, and I cut the middle cross section of each sphere and laid them on top of each other at coincident radius points. I zoomed in so you can see the difference in size. Small difference, but significant and consistent.

Hmm, yea ok.
If you just take the Nordics, Germanics and the Brits, the average brain size for white Caucasoids would be significantly higher.
But hey, what do I know. I'm just sitting at 1700+ cm^3
