Since Google does not employ me, it cannot sack me, but I admit to feeling a little left out of the news recently. In a late bid for notoriety I have put together a series of my previous statements about sex differences, and if you will kindly circulate these as widely as possible someone may seek to censure me, which ought to boost readership.
As a brief introduction, humans are not exempt from sexual dimorphism. Men are taller, and have very much greater upper body strength. They have bigger brains. A fair approach to sex differences is to show all of them by effect size, rather than cherry-pick particular examples. Some purported meta-analyses are far from inclusive, which can misrepresent the total picture.
The majority of psychology researchers subscribe to the view that men and women have “virtually the same levels of intelligence”, by which they mean that men and women are not all that different in their mental abilities, or a little different but counterbalanced, so that the totals come out pretty equal. A minority position is that by early adulthood men have a 2-4 IQ advantage over women. The debate hinges on sample representativeness.
It is generally accepted that men show a wider range of ability, while women cluster a bit more closely round their mean level. There are some exceptions, but it is a general rule. As a consequence of this, even if men and women have exactly the same level of intelligence, there will be more men at the extremes of ability, and thus more men at the highest levels of ability, which tends to get all the attention.
If, in addition, men have a 2-4 IQ point advantage, their over-representation at the higher levels increases considerably.
Here are the latest findings on men and women’s brain sizes and their intelligence levels:
Here sex ratios of math and science ability and general knowledge
The brightest people tend to be male:
Here is an exception to the general that women’s standard deviation of abilities is smaller
Women are more easily hurt and more easily traumatized, even though they have fewer traumatic events
You can find more posts by putting “sex” into the search bar next to my name. I would gather more posts, but I have to rush to a voluntary meeting about diversity. For the avoidance of doubt, I am not arguing in favour of diversity.
Ability is what interests me.
