      Also kind of a weird causal conclusion considering that systematizing is the mediator between sex and math ability. Controlling for mediators often leads people to strange causal conclusions.https://twitter.com/drPaolaBressan/status/1026091338209681410 …

      Why, what a reaction. The tweet simply means that men tend to be better than women at math because men tend to systemize more than women do. Not too trivial either: previous research had concluded that systemizing and math ability are unrelated. https://rdcu.be/3T3W  pic.twitter.com/FEalXwb7sy

      I have yet to see a convincing meta-analysis on this subject. All of the reasonably broad ones I have encountered fail to reject the null for a difference in mean, though most show marginally higher variance for males. Obviously also depends on the subscales and coeffs for g.

      This is about the well-studied male-favoring difference in means on tests of mathematical and visuospatial cognitive abilities. I am aware-- as your OP noted, it arises from greater systematizing tendencies. However, this post does not address the question of g more broadly.

      Completely tangentially, I am quite curious about the extent to which metrics for skill in social and organizational-political domains are correlated with any subscales from any common cognitive tests. It seems to me as though this area is largely missing from direct metrics.

      Seriously, these metrics focus on particular domains of cognitive ability. Yes, a g-factor can be constructed, and it explains a reasonably high proportion of total variance across subscales, but cross-subscale correlations are often shockingly weak: https://en.wikipedia.org/wiki/G_factor_(psychometrics) …pic.twitter.com/JG7MKd05Ao

      Even the proportion of per-subscale variance explained by composite IQ is not enormous (square root of last row). This implies that adding a new subscale (given proper validation) could materially alter any extant difference in mean composite IQ scores by gender.

      Yes. It's known that test developers deliberately designed tests this way to remove sex differences. Eg standard tests have few 3d spatial tests, which show 7 IQ male advantage or so. http://programme.exordo.com/isir2018/delegates/presentation/42/ …

          As expected. Meanwhile trait conscientiousness is apparently correlated with social abilities (as well as income), and tends to significantly favor women.

          The intent is to try to find decent proxies for social ability, which is a type of cognitive ability that tends to be extraordinarily relevant to life success and personal fulfillment.

          Yes, it arguably is. I see no reason why manipulating shapes or words should be considered any more a form of intelligence than manipulating organizational politics or flows of information. The latter is arguably more difficult, and both fit all common definitions of the term.
