wait is it true that IQ tests are normalized for men and women so that both of them get the same average

Sort of. Long story. Items are selected such that men and women tend to get similar overall scores, despite sex differences in some cognitive abilities.

(this is against the common knowledge but)
in the only normed IQ test that will test above 160 (Stanford), doesn't seem to be true; for IQs over 180 there were iirc significantly more girls than boys. probable reason for this is that it's vocab heavy, girls in 1920 read a lot.

Depending on how much weight you give different sections in IQ tests, men or women could get slightly higher average scores. There isn't an objectively right way to do it (I think).

Yes! Women and men have equal average IQs essentially by definition. This is one of the many assumptions baked into IQ tests. I wrote a thread on this a while back:

The second thing you might notice is that men and women score differently. Psychometricians re-weight the questions men tend to get right and the ones women tend to get right so that men and women get the same average scores.

Maybe this is the news that finally knocks Geena Davis off that pedestal I have her on.

Scottish mental survey of 1932 seems to be the go to example - same means, men have more outliers on both sides, in comparison women are grouped closer to the mean. Haven’t seen anything re normalization.
