North east asians have higher IQ's than caucasians. They also have larger and wider brachycephalic skulls. I also believe Jew's who have a 15 point higher average IQ than Germanics have brachycephalic skulls. Negroes have dolichocephalic skulls. An article from the independant sheds light on research on the higher intelligence of brachycephalic peoples.
