@JGBriggsPhD @unherd Yeh, really hard to get a read on how people use social media differently.

Does social media cause mental health to decline? Wrote about the lack of clear cut evidence for @UnHerd https://t.co/9i0sh9s2Sh

Do you think marriage in your society is complicated?

Then check this amazing article by the anthropologist Olympia Campbell (@OLKCampbell).

It is a global tour of marriage traditions and the mechanisms behind them.

Must read!

Marriage customs very different to our own:

• Enga boys in Papua New Guinea join bachelor cults. They are only able to marry after they have proven they can live without dependence on women.

• Among the Nuer of Sudan, dead men still marry and 'have children'.

• The BaYaka marry informally. They simply walk into the forest together and come back married. They can break off their marriages as simply.

• When the French state banned primogeniture, they also decreased their birthrates, as families limited their fertility to stop their estates getting chopped up. (They also increased their rates of cousin marriages.)

Plus: Menstrual huts, where women seclude themselves during their menses, reduce rates of cuckoldry. Read on to find out why!

Happy to answer any other criticisms and hope this makes the article less 'painful' 6/6

[Olympia L K Campbell @OLKCampbell]

I think you misunderstand. I'll respond point by point.
1) This study https://t.co/VI0jOlh4qB does not show the opposite. Table 1 contains some comparative data available on male reproductive success. 1/

[Lyman Stone 石來民 🦬🦬🦬 @lymanstoneky]

this isn't true and the study cited literally shows the opposite

[Olympia L K Campbell @OLKCampbell]

Also, when we talk about farming in evolutionary history what we mean is the domestication of plants and animals. So yes there is an example about pastoralism in a section on 'farming'. (But I would count livestock farmers as farmers anyway). 5/

With essays on:

• Communism had its optimistic, pro-growth reformers too, but they always failed. Today's would-be reformers can learn from them.

• Marriage customs very different to our own, including the "menstrual huts" used by the Dogon people of Mali to reduce the risk of cuckoldry. Apparently, it works!

• How one ugly shrub gave us cabbages, broccoli, Brussels sprouts, kolrahbi and cauliflowers. Gee, thanks.

Plus: why labour laws hold back European tech; how Victorian cities could 10x in under a century; the gold plating of American water; and why today is a golden age of vaccine development.

No system is the default but each is a solution to the same problem - how to manage resources, how to build alliances, and ultimately how to leave behind the most descendants. Read here: https://t.co/cvAjMn0sLR 3/

[Olympia L K Campbell @OLKCampbell]

Humans exhibit an astonishing variety of marriage systems. Sometimes monogamous, other times polygamous, occasionally we even marry ghosts. The diversity can seem to defy any general explanation. In my new piece for @WorksInProgMag, I write about the Darwinian logic behind it. 1/

[Olympia L K Campbell @OLKCampbell]

Marriage systems evolve in response to the ecology and type of wealth. Lots of cows? lots of wives. Large agricultural estates that can't be divided? A fight to be the single inheriting child. 2/
