Do men have bigger brains than women?

Indeed, men do have bigger brain women-with the difference between about 100 g,, after accounting for differences in total body weight. On average, the human brain weighs about 2.7 pounds, or 1,200 grams.

One study analyzed the SAT scores of 100,000 17-and 18-year-olds to a corresponding IQ score and found that male test-takers scored an average of 3.63 IQ points higher than the female test-takers.

The study, however, included about 10,000 more females than males, which may have skewed the results. The study's authors, however, believe that a greater amount of brain tissue, the greater the capability for cognitive processing.
