extraversion and culture

steve sailer says that peter frost says that some researchers found that extraversion is selected for in men in societies that practice polygyny.

as peter put it:

“Extraversion is part of the male toolkit for mating success. It is especially useful in societies where a high incidence of polygyny means too many men must compete for too few women.”

soooo … in an earlier post i pointed out that both austrian and png men decorate themselves with bird feathers but in sliiiiiightly different ways (and with different types of bird feathers, of course, dependent upon what sorts of birds live in austria vs. png).

i wondered why the differences? why are the pngers so much more ostentatious?

maybe i’ve got an answer to that question now. pngers are polygamous while austrians … eh, not so much. so, pngers are naturally (literally) more extraverted than austrians.

extraversion is, of course, a partially heritable trait. i.e. if ur an extrovert (or not), it’s in ur genes — at least in part.

which brings me back (at least in my mind) to my original question: where does culture come from? the answer seems to be: at least partially from our biology.

pngers decorate themselves like this >>

’cause as a population they must have more “genes for extroversion” (whatever those are).

meanwhile, back in austria >>

hbd. cool!

p.s. — peter also said:

“As a single man, I would spend close to $3,000 a year on dating. And that didn’t include things like buying a sportier-looking car.”

whoa. big spender! (~_^)

  1. It’s the old chicken and egg problem.

    Where does polygamy come from? Originally? Extraversion? Where does extraversion come from? The institution of polygamy?

    Strike the root of the the quandary: Why is polygamy unknown in cold climates?
