Assume for the next 3 sentences that this single study is accurate, replicable and does show what it claims to.
So in the patriarchy the guys finished the task 35% faster. In the Matriarchy were the scores relatively equal to the men in the patriarchy, or the women?
Meaning does patriarchy produce a benefit for the men or does it somehow prevent the women from performing as well?
I checked out the actual study. The mean times to complete a four-piece puzzle representing a horse (their measure of ‘spatial ability’) was:
Patrilineal Males: 42.31s
Patrilineal Females: 57.2s
Matrilineal Males: 32.1s
Matrilineal Females: 35.4s
The difference between societies is strongly significant: the matrilineal society was significantly better at completing the puzzle. The sex difference in the patrilineal society is significant. The sex difference in the matrilineal society has a p-value of .025: that is, significant at the 5% level but not at the 1% level. In the matrilineal society, education was equal across genders, which explains a third of how much the gap closed (as education favored males in the patrilineal society).
The medians, though, are screwy:
Patrilineal Males: 32.5s
Patrilineal Females: 42s
Matrilineal Males: 27s
Matrilineal Females: 20s
As expected, the mean is larger than the median for every group. The median female in the matrilineal society, however, finished far faster than the median male in the matrilineal society- despite the males having a faster mean overall. The times overall appear lognormally distributed, but they don’t provide the distributions for each response group. I’d like to take a look at the matrilineal ones and figure out why the median relationship doesn’t align with the mean relationship.
A couple of comments spread throughout the study suggest that this result should be seen as abnormal / barely update your probabilities. (Among other things, they point out that every other study shows no significant link between gender egalitarianism and spatial ability, and so this study is significant as the first one that shows something like that.)
Be interesting to stuff a bunch of heads (still attached to their bodies of course) into an fMRI while doing spatial reasoning and see if a trained observer could reliably sort them by sex. Or even gender.

I see at least two obvious confounding variables that can wildly influence this measure. (And I’m not saying I have any better measures to suggest.) The first question is whether fast hand movements are considered appropriate in the given society. If the norm for your gender is gentle, majestic movement, that slows you down. The second question is what your society’s gender norms are for deliberateness/decisiveness.

Or c), does matriarchy prevent men from performing as well as they could biologically?
I’m not saying that I think this is the reason, just that I don’t have evidence to rule it out.
