Not really true.

It’s widely accepted that the average intelligence is the same for male and women, but the variance is larger among men.

Of course women are capable in chess, and there are women capable of beating nearly everyone with extreme ease.

However, when looking and the very tail of the distribution, you will find mostly men due to the higher variance.

Hence, more men Nobel prizes, more man chess champions, etc...

I am not ruling out societal factors, but way too many people today rule out biological differences altogether!
