I think that says more about the people you're hanging around with, rather than women in general. I know plenty who are genuinely curious about such things (and you can find a plethora in the news, university faculties, on message boards, etc.)
I'd believe that, but the men I hang out with tend to be genuinely curious people, so the so-called "control group" shows that I should be encountering at least as many curious women as men, and yet, I don't see that. So what else?
It could be many things other than a lack of curious women in the population at large. Not saying any of these are true, obviously, but some possibilities: You have biases (conscious or unconscious) in the "type" of woman you befriend? Social signaling or dynamics in your conversations leading to not discussing curiosity-inspiring topics with women? You are not interested in the specific areas or things they are curious about? Etc.
Could be a billion things. I'm simply expressing what I've observed in my humble little life. I've worked in retail, dug ditches, journalism, design, high tech. I've lived in red state and blue, in big cities and small rural farming communities and everything in between. I've befriended every kind of person you can imagine, from Ivy league stars to GED earners to drop outs, drug addicts, executives and criminals.
I'm not saying any of this necessarily gives my opinions more weight, but I like to think I've seen enough to feel I can recognize a pattern when I see it.
