@sickburnbro fantastic post, except that the justification is slightly flawed
as the economy becomes more complex, contributions to GDP are more and more dominated by the right tail, which is mainly male due to men because men have a higher variance
this is running off of the studies that produced the first attached image. The problem is that these studies all sampled children aged 8-13, where most women had several years of puberty, while only some males had begun puberty. This explains why the results have a higher variance for men, and why women appear to have a higher IQ than is generally observed in reality.
The real distribution is closer to pic 2, with women following a similar curve but falling off the right tail more readily compared to men.
mental retardation is greater among males than females, therefore your second graph is incorrect

Irwing and Lynn (2005) also discussed this in their meta study investigating sex differences in means and variability on the progressive matrices
>the finding in this meta-analysis that there is no sex difference in variance on the Advanced Progressive Matrices and that females show greater variance on the Standard Progressive Matrices is also contrary to the frequently made contention, documented in the introduction, that the variance of intelligence is greater among males. This result should be generalizable to the general population of normal intelligence. The greater male variance theory may, however, be correct for general population samples that include the mentally retarded

Note that Irwing and Lynn proposed a 0.33d (~5 points) difference in mean IQ with no difference in SD. Your graph (2nd attached pic) suggests a ~0.5d (~7.5 points) difference in mean IQ and a sizable difference in SD
@billiam @sickburnbro @white_male Interesting, I'll have to look into these. Regardless of which specific scientific reasoning used, I think OP's point still stands as virtually every single inventor, mathematician, scientist etc. of any note have been male, and there's zero evidence to suggest this would change in the future.
Also CC: @Tfmonkey because he introduced me to the flaws in variability hypothesis years ago but I can't find his video anymore.
I have seen it suggested that the heterogametic sex will have more variability due to having more genes.
The heterogametic sex is the sex of a species where an individual's gametes have non-matching sex chromosomes.
In humans, males are the heterogametic sex (XY), while females are the homogametic sex (XX)
While the X chromosome is larger than the Y, only one X chromosome is active for women, whereas men have both an active X and an active Y.
There is some discussion here: https://l.opnxng.com/r/evolution/comments/58xk7z/what_causes_higher_variance_in_male_than_female/
Searching "sexual dimorphism heterogametic sex" is a fairly good way to find info on the subject
In birds (and some fish, some insects), males are the homogametic sex (ZZ chromosome), while females are the heterogametic sex (ZW). It's not that uncommon for females to be bigger (on average) than males in birds (it's very uncommon in mammals).

@billiam @sickburnbro @veff @white_male the first chart that shows boys and girls have the same mean IQ was taken using children 11-13 wherein girls have a once in a lifetime developmental advantage due to starting puberty at 11 (while boys start at 13).
The second chart (showing boys have higher IQs) was taken using 17 year old high school students. Saying it's wrong because more boys are retarded is egalitarian cope.
They didn't though and they completely disclosed what they did. They didn't preselect data points from their test subjects.
The popular use and extrapolation of the results further in the information chain is misleading.
Also, check out this paper about differences in general knowledge (which is distinct from intelligence)
> The magnitude of the male advantage ... amounts to 0.51d or approximately half a standard deviation
> Males have greater knowledge than females in Current Affairs (0.82d), Physical Health and Recreation (0.75d), Science (0.58d), and Arts (0.31d), but females have substantially greater knowledge than males in Family ( -0.46d), while there is no sex difference in Fashion ( -0.01d).

you shouldn't be looking at individual studies, but rather collections of studies / meta-studies.
I'm not an egalitarian.
The majority of evidence supports the notion that mental retardation is higher in males. There were no studies found by Ellis et al which supported the opposite conclusion.
The book of Ellis et al isn't egalitarian either.
