sauce: Race, Evolution, and Behavior by Philipe Rushton. that's a picture taken of a page 
Sauce?

I'll ignore that for this.....
John Philippe Rushton (December 3, 1943 – October 2, 2012) was a Canadian psychologist and author. He taught at the University of Western Ontario who became known to the general public during the 1980s and 1990s for research on race and intelligence, race and crime, and other apparent racial variations. His book Race, Evolution, and Behavior (1995) is about the application of r/K selection theory to humans.
Rushton's controversial work was heavily criticized by the scientific community for the questionable quality of its research,[1] with many alleging that it was conducted under a racist agenda.[2] Since 2002, he was head of the Pioneer Fund, a research foundation that has been widely accused of being racist.[3]
Once again, you post something from a fucking looney. BTW, brain size has nothing to do with actual intelligence...
