I haven’t read the whole thread, and that isn’t usually how I operate, but I had to jump in here.
First, I have to disagree that women tend to be more cooperative, and second, while I cannot disagree that women have more estrogen (on average), and estrogen does give our skin a bit of softness over men’s (on average), I am not sure that is what the OP means by “softer.”
In regard to women being more cooperative-- I think a lot of women want to believe that, and it’s often in the press statement, but it isn’t my experience.
When I was in the army, women drove me nuts with their unwillingness to work with someone with whom they had some minor grudge (and by work, I don’t mean long-term in-depth tasks-- I mean loading a truck with duffel bags). They’d be perfectly willing to spend more time than the original task would actually have taken, explaining why they can’t work with So-and-so, or just plain bitching about her.
Men can work with other men they don’t like in order to get something over with. If a sergeant passed a group of privates, among whom were a few who did not like each other at all, and the sergeant bellowed at them to do some task, they’d just do it. They’d do the bare minimum, but they’d get it done, and they wouldn’t let personalities interfere.
To be fair, when you had a group of women who all wanted to work together, they’d go much further than required, and do a much better job relative to a group of men, regardless of how the men felt about one another.
But the odds of a random group of women all being friends wasn’t great, and so usually bellowing at a random group of women to do something was a mistake.
With mixed groups, it kinda depended on the mix, and exactly what kind of animosity you had between to women. Most of the women in a mixed group would pitch in the same as the men, but there might be two who would refuse to work at all-- that might not matter, though, and there’d probably be enough people to do that task without the two who were acting like 12-yr-olds.
I will say, though, that experienced Drill Sergeants seemed to have things figured out-- women volunteer for details more readily than men do, so when a truck needed loaded, or the laundry room needed detailing, the DS would call for volunteers-- “I need 5 Mad Dogs to CQ now!” and we’d scurry off. 6 or 7 would show up at CQ.
Men rarely volunteered for anything, but they didn’t bitch when they “got volunteered.” Wow, could women go on about how unfair that was, though-- women in the freaking army.
When you think about that, though, the net result is they same-- you get about the same number of non-complaining men as women.
I can’t really say just what is going on there, but it is something fundamentally different between men and women, at least in the US. I have no idea how much is nature and how much is nurture, though.
I would love to see repeated some of the classic experiments on obeying authority, like the Milgram experiment, repeated but separating men subjects from women in order to get separate data for each gender.
