the final point that i want to look at from the woodley & bell paper on consanguinity and democracy is their finding that pathogen load affects consanguinity (which, in turn, affects democracy) in societies. before i do that, though, i want to back up and look at pathogens and culture.

in 2008, fincher, et al., published their findings [opens pdf] of an apparent relationship between individualistic vs. collectivist societies and pathogen load. generally, the more pathogens in your environment, the more collectivist — ethnocentric, conforming — you’re gonna be since limiting your interactions with strangers will help to reduce your chances of catching some lethal disease. and vice versa.

i like it! (^_^)

here’s a nice little chart from the paper showing the correlation between individualism (taken from hofstede 2001) and historical pathogen prevelance (the authors explain how they came up with their pathogen index on pgs. 1280-81):

two of the et al. guys, murray and schaller, expanded the historic pathogen index in a paper published in 2010 [opens pdf]. the index (or, rather, indices ’cause there’s two of them) sums up the historic disease prevalence for 230 nations or geopolitical regions. they offer (pg. 102) a nice table summarizing several different studies which found correlations between pathogen load and things like individualism vs. collectivism, extraversion, openness and democratization (click on chart for LARGER view):

again, in general, the more pathogens, the more cultural/behavioral “restrictions.” (but the spicier the food! mmmmm!)

more on all this anon!

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! (~_^)
