Paper claims “men’s height gains were 2.76 times larger than women’s in the first half of the twentieth century” in UK but for their results to be right UK would have had to have ranked roughly 197th out of 200 countries in female height gained during first half of the 20th c. by NCD-RisC estimates

This nonsense claim from this paper is making rounds on Twitter, claiming fertility & gender (in)equality correlated at .81. But the Gender Inequality Index includes adolescent fertility as part of the measure! When you rebuild the index without circular reproductive outcomes correlation cut in half

Another interesting pattern: leatherworking is commonly done by women in hunting and fishing societies, but in agricultural societies where it is a specialized craft it is nearly always done by men.

While I've seen both men and women building Hadza huts, much more often it is women (pictured). The sexual division of labour lit has zeroed in on hunting-vs-gathering; but much less is said about women's differential contributions to water-fetching, food-preparation, cooking, and house-building.

The sexual division of labour regarding house construction shows a very consistent pattern cross-culturally: women usually construct the shelters in nomadic societies, while in sedentary societies men do it.

“The idea that humans evolved to be protective & sensitive to harm directed towards women appears increasingly popular in evolutionary psych [but] ethnographic evidence conflict with this perspective, [which seems] rooted in contemporary WEIRD values rather than an evolved psychological mechanism”

Evolutionary psychologists have claimed that "humans evolved heightened sensitivity to harm directed at women." This excellent (albeit at times gruesome) post makes the point that the ethnographic evidence does not really support this narrative.

“when a man is publicly accused of being a sorcerer he normally denies that he is. Nevertheless, some men have confided to me that they have successfully performed sorcery and they have told me whom they killed, how they did it, and why…They have even offered to teach me how to perform sorcery…”
