We've accepted a value system in the west that more males in a field == bad, unless that field is physically dangerous or otherwise undesirable. So the sex composition of things is noticed and considered important.

However, note that every frontier field is male-skewed, probably due to lower male risk-aversion. So this philosophy is anti-innovation.

There is some statistical evidence that males have higher variance in general. CEOs are mostly male, people in extremely advanced math classes are mostly male, but at the same time people in prison are mostly male, and people performing dirty and dangerous labor are mostly male. Since personal utility is logarithmic in success, but visibility is close to linear, it's very easy to miss the importance of this other side of the issue, but it's there and IMO not sufficiently talked about (likely because saying "X has high variance" has no bearing on whether X is high or low, and is therefore not really useful to any side trying to make a political point).
