Scientific Blackpill: Difference between revisions

* 8-4 thousand years ago, around the time Agricultural Civilization began to emerge, women's effective population size grew substantially to around 17 times the size of men's.

* This disparity can possibly be explained by increasingly polygynous mating practices that resulted from increased wealth and wealth inequality between men.

* The development of agriculture and more centralized political systems led to greater variance in male fitness due to inheritance of resources and social status (hereditary systems of political and religious succession, i.e chiefdoms, hereditary priesthood, early monarchies).

* Societies that practice monogamy tend to show roughly equal ratios of male to female reproductive success, while societies that favor serial monogamy or polygyny tend to cause more variation in male reproductive success, while not affecting female success in the same way.

Note: This study was misquoted by Pacific Standard (psmag.com) to imply that ''17 women reproduced for every one man''. In truth, only the ''effective population size'' of women was 17 times as large as men's. The effective population size does not clearly distinguish parents and their offspring due to the similarity of their genes. A man with 20 children, each of which has 10 children in turn, would not contribute with 1 + 20 × 10 individuals to the effective population size, but considerably less than that. Anyhow, the result still points to substantial sex differences in variance of reproductive success. Reputed social psychology professor Roy Baumeister, estimated the sex ratio of historical reproductive success to be 2:1. Half the branches on a tree of ancestors represent males, but half of the males are repeats. The observation that males (humans and in the animal kingdom in general) exhibit a greater variance in reproductive success as compared to females is known as [[Bateman's Principle]].
