In this 1996 talk, psychology professor Philippe Rushton says that the average black officer in the U.S. armed forces has a higher IQ and more cranial capacity than the average white recruit.<\/p>\n
Black men have larger brains than white women, even correcting for body size, but lower average IQs. White women have much smaller brains than white men but similar IQs (perhaps as low as five points lower). Women do much worse than men in dynamic spatial ability. Most of the human brain goes to keeping the body balanced and so men who historically were hunting, would have greater need for an ability to orient yourself in space.<\/p>\n
When you have a computer and you want more capacity to write, you need to add more RAM memory, but if you want to work with graphics, you need dramatically more RAM.<\/p>\n
