How can you possibly assert that the differences found between the male and female gamers in that study represent innate qualities of either sex? All of the test subjects have been raised in a society that encourages certain gendered behaviors and attitudes; they have been conditioned throughout their lives, and "contaminated" by society's expectations and teachings. The only way to begin to judge innate differences would be to take boys and girls from birth and raise them in exactly the same manner, and even that probably wouldn't be conclusive.
