In some domains, women are more sexually selected than men; one could say in these cases that women have the larger “peacock’s tail.” An example can … - Steve Stewart-Williams

As memetic evolution picked up steam, humans were transformed. No longer were we devices designed solely to pass on our genes. Suddenly, we became hybrid creatures, torn between passing on our genes and passing on our memes. This vision of our species helps to explain much of what most puzzled the alien scientist: our moral systems, our religions, our art and music and science. Cultural evolution is the key to unravelling the deepest mysteries of the human animal.

A danger in emphasizing mean values for each sex is that these values may be projected onto all or most normally developing men and women. The mean may be treated as a description of the typical group member, despite the fact that the majority of individuals fall above or below it. Psychologists do make some effort to stress that means cannot be attributed to all members of any group, as evidenced by the fact that we often append the phrase “on average” to our descriptions of mean differences. But is this enough? Consider again the robust sex difference in willingness to engage in casual sex: The mean SO [sociosexuality] score for men is higher than that for women. What does this tell us, though, about individual men and women? It clearly does not tell us that all men are interested in casual sex and that all women are not. However, given the degree of overlap between the male and female distributions, it also does not tell us that a large majority of men are more interested in casual sex than a large majority of women. That is, it is not accurate to say even that “men are typically more interested in casual sex than women, but there are of course exceptions.” Here is what the data that the means are drawn from actually tell us:
