So because there was once a pseudoscience regarding the human brain, any study of the human brain is now rendered as pseudoscience? Someone better tell all those chemical engineers to stop bothering with alchemy.
Also, the difference in behavior, if it is caused by genetics, does not necessarily require a difference in brain size/structure. For instance, blacks have on average 19-21% more free testosterone than whites, and testosterone is associated with increased aggression. That is a purely hormonal cause that could offer an explanation for the data.
