The whole "across cultures" thing in that 1 (importantly, <i></i>one<i></i>) study is easily explained by a couple things:<p>- men grow more muscle faster and that used to be important<p>- childbirth used to be (and in many places still is) very dangerous for women<p>Consequently most societies defined gender roles in similar ways, leading to similar effects across them.<p>Or you can go even simpler and say they're more neurotic because their odds of being raped by a man are terrifyingly high. Or they get paid less than men and charged more for things like health care, car loans and mortgages so they carry a higher financial stress burden. Or their health plans are inadequate and they're worried about what will happen if that matters. Or they're being harassed in the workplace.<p>Or you can dispute the premise entirely and say the standard for "neuroticism" was based on a culture created and still dominated by men.<p>---<p>A lot of people are saying things like, "he didn't really write anything that was sexist or misogynistic", but women and people of color are far too familiar with fucked up policies justified by "biological differences". There are real, deep, life and death social problems right now caused by misogyny and they all stem from the fundamental idea that women have their role and men have theirs.<p>What does this lead to? Health care policies that cost women more and don't even meet all their needs. Health care systems that service women less effectively than men (stroke symptoms are often missed in women, childbirth mortality rates in less progressive parts of the US, etc.), jobs that pay women less than men, laws that ignore or oppress women, etc. etc. etc. etc. And every time, it's justified with "women are just biologically different than men".<p>Why can't you express such an opinion in the workplace? Because that opinion is responsible for the oppression of billions of women throughout the entire history of humanity. It's not at all like arguing for wind over solar, or honestly other political debates over private vs. public health care or whatever. When you're talking about social issues, you're talking about systems that have oppressed, brutalized and murdered unbelievable numbers of people, and continue to oppress people that you work with and see each and every day. They're not idle thought experiments or a curious hobbies. Treat them with the sensitivity they deserve.
