where everybody’s fourth cousins

in response to the “people befriend their fourth cousins” study, smersh makes an excellent observation:

“You referenced some of this in your counter currents interview but this study makes things more clear.

Friends are as close to each other as fourth cousins.

Jews are also as close to each other as fourth or fifth cousins.

Therefore it is easy for Jews to make close friends by hanging out with other Jews.

Meanwhile, it is harder for gentiles to make close friends in mass societies, as people move around and no longer live in a village near a bunch of closely related people.

Certainly seems like it might explain a lot without implying a malicious intent on the part of certain parties.”

yes! maybe.

if it’s correct that people generally befriend their fourth cousins — and this is something that could vary between different populations (Further Research is RequiredTM) — then, perhaps, this could explain why places like iceland work so well, too. i don’t know what the average relatedness there is (does anybody know?), but presumably it’s something like fourth or fifth cousins as well. maybe then it IS really easy in such a place to have a — whatever — redistributive socialist system when it feels like almost anyone in your population could be your friend.

dunno.

btw, that counter currents interview was, in fact, originally a hoover hog interview that somehow got syndicated over on cc. just want to give credit where credit is due. (^_^)

J.P. Rushton’s theory of ethnic nepotism [pdf] – “Ethnic nepotism due to similarity is a weak social force compared to social identity. However its pervasiveness makes it a potential driver of evolutionary and social change, a potential borne out by sociological studies of the impact of ethnic diversity on social cohesion and public altruism. Genomics confirms the theory for interactions within populations with sufficient genetic diversity, such as ethnically mixed societies. GST [genetic similarity theory] applied to ethnicity is promising for further research in evolutionary social science because it unifies evolutionary and behavioral mechanisms in a single theory.” – from salter and harpending. h/t hbd bibliography!
