=== "There is controversy about sex difference but there seems to be a fair amount of agreement that men do tend to have better visual spatial skills. However, I am not sure we can say that makes them more intelligent."===
Of course men, on average, are more intelligent. But intelligence is somewhat a subjective term. If one deems it "the mental capacity required to survive", then I think the answer is a clear yes.
Visual/Spacial skills are extremely important if hunting down food in the crudest sense, or fighting in modern warfare in the most recent sense.
This is not to say men are "better" than women because it is not a matter of who is better. Men are better at some things, women are better at others.
The world would be a hell of a place if men were left to raise children. The kids would be sitting in smelly diapers for days while dad tried to figure out how to reach level 45 on a video game.
STUDIES LIKE THIS ARE for explaination, NOT LIMITATION.
Why do you say men are more intelligent on average? My understanding is that while the average intelligence is approximately the same for both men and women, there are more very intelligent men and very stupid men than there are very intelligent women and very stupid women. While the average is the same, men populate the extremes to a greater extent.
"intelligence is a subjective term"My thoughts as well.You hit the nail on the head re:men are better at some things,women better at others.imo/this specialization(of skills+intelligence)allowed humans to survive and evolve from tree dwelling proto humans to modern homosapiens.
"Of course men, on average, are more intelligent. But intelligence is somewhat a subjective term. If one deems it "the mental capacity required to survive", then I think the answer is a clear yes."
Actually, men are NOT, on average, more intelligent. Men have a slightly higher incidence of genius than women, but they also have a slightly higher incidence of low-IQ and retardation.
