Depending on which study you look at, median IQs are either the same or men are a smidge higher. The standard deviation is much greater for men though - so more physicist level IQs, and more glue-eating retards who end up in jail because they were dumb enough to call the cops to report someone stealing their meth or somesuch.
I've heard this called Male Mutation Bias. The Male distribution is wider with more outliers, the female is more narrow with a taller normal distribution. IIRC, in North West Europeans the males are on average 5 IQ higher than females, though adolescent females are higher than same age males due to early onset puberty and maturation.
It makes sense from a biological perspective. Almost all women reproduced until the last 50 years or so, while a LOT of men were reproductive dead ends. It's the same reason you might risk $50 on Dogecoin going to the moon, but you're going to put the majority of your assets into lower risk investments.
