Software development is playing with legos for a living, except with a billion pieces and the ability to make your own pieces, with infinite floor space. It’s “thing-oriented” and only grey if you start mingling in the secondary designers, managers, and such external requirements. But it’s fundamentally “thing oriented” like nursing is fundamentally “people oriented” despite the variety of equipment and tools a nurse must be familiar with to do their job.

Look at the chart. "Computer and mathematical occupations" is male majority, but not male-dominated like say train drivers or mechanical engineers. Some subfields (web and interface designers, notably) are pretty balanced.

We study diseases by (first) looking at people who have severe forms. Ie it would be tough to come up with an understanding of autism just by studying the brains of people who are "a little aspy". If you can figure out what causes the gender segregation of train drivers / pediatricians, maybe you can apply that knowledge to relatively-mildly-imbalanced tech fields.

I'm still not convinced, the amount of "social pressure" from day 0 (or even before) for a kid is just shocking (starting with: I won't buy a pink doll to my newborn baby boy).

Obviously with animals is different, but there might also be other things at play that we are not aware.

Happy to be wrong, but I think there are so many layers to make a call at this point that sure, there might be an influence, but society is probably what affects this the most.
