Since the human brain and its interaction with culture is very complicated, more research is needed. But a fair reading of what we have so far would seem to indicate: it's both.
Beware of ideological just-so stories that make you feel good. Also, if it sounds messy and complicated, it sounds like actual biology and psychology.
It looks like there is only indirect evidence, and no direct evidence. In fact, the whole discussion smells far too much of "correlation means causation" to get anything useful out of it.
There are some great weasel words like: "there is good evidence ... play a role ..."
Without a hypothetical mechanism, this is all quite speculative.

Well, remember that Damore's claim was that there is evidence that we cannot categorically rule out biological causes for the skewed representation, in addition to discrimination.
For that claim, even much weaker evidence than what exists would have been sufficient.
Nah. His claim was that there was enough evidence to question policies (secret policies that were in violation of those public core values and probably also the law) that are based on the completely unfounded assumption that discrimination/bias/oppression is the only possible cause for unequal representation.
It's more like Damore's claim was that specific corporate policy were based on the assumption of the opposite. Also, he did not reject Google's core values, unless you take a biased and imputational reading.
> It's more like Damore's claim was that specific corporate policy were based on the assumption of the opposite
No, while that was a supporting claim, the conclusory claims everything in the manifesto are offered to support are that specific policy changes are justified.
> Also, he did not reject Google's core values, unless you take a biased and imputational reading.
As an example, empathy is a core publicly-stated internal value of Google which Damore explicitly called for de-emphasizing. There's nothing “biased and imputational” about reading Damore’s words to mean what they explicitly say.
"We should not base our corporate policy on the completely unproven and highly unlikely assumption that oppression is the only possible cause of unequal representation"
There, fixed that for you.
Also, the research is not at all speculative, quite the opposite. It is immeasurably more solid than the blind assertion that unequal representation is caused entirely/solely by oppression/discrimination etc., for which there is very little evidence overall, and virtually none that holds up to any sort of scrutiny.
Utilizing MRI and cognitive tests data from the Human Connectome project (N = 900), sex differences in general intelligence (g) and molar brain characteristics were examined. Total brain volume, cortical surface area, and white and gray matter correlated 0.1–0.3 with g for both sexes, whereas cortical thickness and gray/white matter ratio showed less consistent associations with g. Males displayed higher scores on most of the brain characteristics, even after correcting for body size, and also scored approximately one fourth of a standard deviation higher on g. Mediation analyses and the Method of Correlated Vectors both indicated that the sex difference in g is mediated by general brain characteristics. Selecting a subsample of males and females who were matched on g further suggest that larger brains, on average, lead to higher g, whereas similar levels of g do not necessarily imply equal brain sizes."
The study examined female and male brains, found that males on average had a higher general intelligence score and a higher standard deviation. The study also found that male brains had on average higher surface area and size even if you control for body size. The study found that brain size in both genders on average leads to a higher g.
I don't understand how your criticism "indirect correlational evidence" applies to this study, could you maybe elaborate on how you would improve this study?
Well hell, the Newtonian laws of motion had no hypothetical mechanism for gravity for a rather long time. We're still in the early days of figuring out Homo sapiens. Don't get your knickers in a bunch, yet. It looks like you're uptight about something.
