:shrug: simply because it happened to be on the top of my head:
The bad news is that gentlemanly behavior makes people happy.
Also because it hit all the morning talk shows and stuck in my brain housing group:
Relationships with egalitarian gender roles are tied to lower marital and sexual satisfaction for women[/url].
Research indicates that the endorsement of sexist ideology is linked to higher subjective wellbeing for both men and women...For women, the palliative effect of BS was indirect and occurred because BS-ideology positioning women as deserving of men’s adoration and protection was linked to general perceptions of gender relations as fair and equitable, which in turn predicted greater levels of life satisfaction....
If you would like me to go out, find, and then reference a bazillion articles confirming that we are indeed mammals, and like almost all of them, but definitely including our closest cousins, we evolved gender role differentiation to better divide labor towards relative strengths, that is possible as well. I admit, however, that I continue to be flummoxed by the political side of the aisle that most ardently insists we teach evolution in all our schools being the same one that denies so vigorously its' bequeathment. Men and women are both made wondrously and wondrously different. That's not controlling for all individuals - you have outliers everywhere. But just as you can say "males are bigger than females", recognizing that there are some small men and some large women, but that the two bell curves have significantly different apexes, you can say that gender roles work better for more people for more life satisfaction because it more neatly fits with how we are made. As an example,
women's brains respond differently to the sound of a baby crying,
Oxytocin, the "cuddle horomone", is released during breastfeeding, enabling intense bonding between mother and baby that isn't replicated for the gender who can't excrete milk.
Women are also better at multitasking, while
men are generally better at focusing on one task. Etc. etc. etc.
The counter is usually to declare some kind of denunciation of the absolute application of the principle, but that is a strawman against an argument that isn't being advanced. We are talking about broad application for the general mean of humankind.
Since we abandoned those, however,
women have become less happy, flipping an advantage in wellbeing over men in the 1970s to a disadvantage today.
Oh.
Except for conservative women.
