    Sex differences in personality, but also in cognitive and bodily traits, become lager in more gender-egalitarian countries, and it are men who do most of the changing. https://www.amazon.com/Human-Diversity-Biology-Gender-Class-ebook/dp/B07Y8K5FX8/ref=sr_1_1?crid=21HKE707E8U75&keywords=human+diversity&qid=1580307007&s=digital-text&sprefix=human+div%2Cdigital-text%2C251&sr=1-1 …pic.twitter.com/1pMix1tYYE

        I think the most amazing example for the above trend is waist-to-hip ratio: The sex difference - women being curvier than men - is larger in more gender egalitarian countries.https://twitter.com/DegenRolf/status/1040871310946123776?s=20 …

        How does sexual selection differ between the two countries?

        Most mate choice criteria don't differ notably across cultures, to my knowledge. WHR could be a different case, but I am not sure.

        If it's men who change, how is it at all plausible that the change is due to oppression of women?

        Right? I would say it's the men that don't shine under (economic) oppression. And it's more 'girls will be girls' than 'boys will be boys'.

        I'd guess this is mainly due to men adapting to female demand being less for male material resources & stability, & more for male hotness.

        I think that (evo psych/econ) "demand from the opposite sex"-perspective of gender roles is under-rated. Cf.https://twitter.com/sentientist/status/939487093566398465 …

        That makes sense if you change it to "the deprivation of freedoms both sexes experience in developing countries suppresses the expression of dimorphism"

        Is there a chance that the causing factor is calories rather than freedoms? It would make sense to me if mothers who get few calories epigenetically trigger their sons to grow more calorie-efficient (smaller) bodies, probably via less testosterone.

        Does: advanced society -> more natal calories -> larger male bodies (via testosterone) -> lower agreeableness hang together intuitively?
