The finding
What the evidence shows
Men's brains do average larger than women's, but the commonly cited figures run higher than stated here: around 1,260 cubic centimeters for men and 1,130 for women, not 1,200 and 950 to 1,000. The women's figure in particular understates the accepted average by a meaningful margin.
