Brain Size and Cognitive Ability

Studies have been done on large populations of men, women, Europeans, Africans, Asians, adjusted by body size, and correlated, and have found that Asians have the largest brains on average (say, 1350 cc), Europeans in the middle (say, 1300 cc), and Africans the smallest(say, 1250 cc); while men have larger (say, 1300 cc) brains than women (say, 1200 cc.)  Intelligence tests, again of large populations, show Asians to have the highest IQs (115), Europeans the middle (100), Africans the lowest (85); whereas women have, possibly, slightly lower (96) IQs than men (100). 381 more words
