Shh. :crazy:

If there are more males at the genius and retarded ends compared to females then the averages for the two sexes would probably be different (maybe they would have to be different - a mathematician may know).

Edit:

Consider these two sets:

A: 1,10,1
B: 2,10,2

Mean of:
A = 4
B = 4.6

I'd be interested in a reference, thanks.

Ok. Not right now but I'll get it later.

Some stuff here from a British researcher:

Universally, men tend to score higher on certain specialized skills, such as spatial awareness. In the real world, that means they might be better at reading maps or navigating. Women score higher in terms of language development and emotional intelligence. But most experts agree there is no real, important overall difference when it comes to gender and intelligence.


What I study is "perceived intelligence," essentially how smart people think they are. I analyzed 30 international studies, and what I found was that women, across the world, tend to underplay their intelligence, while men overstate it.

So do most men think they're Albert Einstein?
There certainly is a greater male ego. It's what we call the male hubris and female humility effect. Men are more confident about their IQ. These studies show that on average, women underestimate their IQ scores by about five points while men overestimate their own IQs.


Although [men and women] are on average the same, the people at the very top and the very bottom of the IQ bell curve are more likely to be men. That is a pattern that we see in the university setting, with men either being at the very top of the class or at the bottom.

Here you go Segundo:

Gender differences are biological and not just cultural: the biological foundation for gender differences includes hormonal influences on the brain (Berger, 2003). These differences begin in the fetal stage of development, when the sex hormones begin to influence brain development, which continues to develop throughout childhood. These gender differences in brain maturation produces different overall development, such as the fact that infant girls tend to talk earlier than boys, and their language development continues to be more advanced than boys throughout early childhood (Fenson et al., 1994; Leaper, Anderson and Sanders, 1998).

That's interesting that females mature faster than males. A relationship between rate of maturity and intelligence has been found, so if females mature faster than males than we should expect the two groups to have different IQ averages - which would be in line with Lynn's finding.

I think you have to look at a meta analysis of IQ studies before you can say there's a definite pattern so I wouldn't put all your eggs in Lynn's basket. (You also have to agree what IQ is of course ;) )

EDIT: I note that some of Lynn's findings were based on a meta analysis he did but I don't know enough of the field to comment on its validity.
