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.
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 …

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.

I'd say the evidence on general intelligence is inconclusive due to a variety of reasons but especially psychometric and sampling issues. But my posterior mode is on male advantage of perhaps 3 IQ.
-
Regarding sampling issues, definitely, particularly if one hypothesizes that late developmental effects (e.g. during ages 20-30) might contribute to any deviation that does exist. Very difficult to sample.
-
I skimmed through abstracts from a few more modern reviews, and everything I see is at ~0-2. Possible age-dependent effects. This is all further dependent on the extent to which each of the respective tests manage to capture e.g. spatial abilities, social abilities, etc.

You make a good general point, yet my formulation is meant indeed to indicate mediation, not causation. “B mediates the relation between A and C” can be less stuffily expressed as “A relates to C because of B”. This does not imply that B causes C. https://go.nature.com/2O8EtCC

Even your wording, "because of B" I would generally interpret as causal, but it could be taken not to be. But pretty much every normal reader will take it as causal I would think.

Gender and maths, no? The mediator between sex and maths is surely going to be some kind of weird porn involving really complicated formulae and unexpected angles.
