        Some more details on how men were more artistically productive in societies where there was a scarcity of women. https://icscpress.com/journals/jge/jge-0202/jge-2017-04-02-01-04/ … https://www.psychologytoday.com/nz/blog/the-human-beast/201604/art-is-more-about-work-sex …pic.twitter.com/uTEPb77u42

        That theory is actually disproved by sub-Saharan societies. Yes, women outnumber men there, but that imbalance is more than offset by the high rate of polygyny. Women are much more in short supply in East Asia and Western Europe.

        … but that is a recent historical development in the case of Western Europe. There was a surplus of unmated women throughout the Western world until the 1980s.

        I wonder what they did when there was the opposite situation in effect? Be more materially productive?

        Depends... I wonder if the increase in artistic productivity cuts into material productivity or if this increase in artistic productivity is a part of a an increase in productivity in general?
