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!

i call b.s.

dennis links to roissy who links to barking up the wrong tree who posts about a study which purportedly shows that human mate selection is more about “market conditions” than assortative mating.

possibly. but the researchers haven’t shown that in this particular study because the people they studied (speed daters) WERE ALREADY SELF-SORTED. see here:

65%+ of them were college graduates versus 20% of the population at large (“bhps” — british household panel survey — column). 83% of the men were in skilled or professional jobs while 86% of the women were — compared to 40% and 52% of the general population respectively.

as bruce said over @dennis’: “Key concept: range restriction.”

yup. these people didn’t have to worry about finding a “like” partner out of this sub-group of the population ’cause they were all already pretty alike. they could just pick the nearest warm body to mate with ’cause they had already self-sorted.

total b.s.

the lady doth protest too much, methinks

here’s an interesting post from an anthro professor regarding a study done on ovulation in female humans and display (studied through shopping habits). the results of the study found that women bought sexier clothing when they were ovulating as opposed to when they were not.

however, there were some problems with the research. for one, as the anthro prof rightly points out, because of the way the researchers checked the hormone levels of the women in the study, they might have erroneously included some women who were not ovulating. oops. also, the study group was composed of, as per usual, western college students and they might not be 100% representative of all women on the planet.

however, as the anthro prof herself admitted:

“I have noticed more cycle-related variation in emotion [since she had a baby]. In particular, my patience and tolerance for rude behavior, and my tendency to cry sentimentally at even the lamest greeting card, skyrocket in my premenstrual phase. I already have low tolerance for rudeness, and I already cry easily. But something about progesterone decline — which is a normal process towards the end of ovulatory cycles — seems to make it harder for me to repress these behaviors in order to fit in culturally with those around me.

“I tell this to you to say, I don’t doubt that hormones, and hormonal variation through the cycle, plays some role in variation in female behavior and emotion.”

hormonal variation plays some role in female behavior and emotion?! gimme a break. hormonal variation plays a HUGE role in female behavior and emotion! not that there’s anything wrong with that. (~_^) that’s just how it works.

good lord. people really have to get over the notion that humans are “rational actors” and come to terms with the fact that we are just a bunch o’ animals like the rest of the creatures on this planet. we (some of us) do have some capacity for rational thought, but most people run around most of them time operating on automatic pilot. they just feel like they’re the ones making all the decisions. that, however, is (prolly) mostly an illusion.

also, the anthro prof seems kinda stuck on the idea that western women are “objectified.” i get the impression (maybe i’m wrong) that she doesn’t really like that idea, either. she suggests that western women buy more sexy clothes due to this objectification process. it’s something cultural, i guess. i dunno.

well, maybe. but plenty of women i have known like to be looked at and admired (by the right guys) — kinda. like. objects. and men apparently see scantily clad women as objects — in their brains, that is. not that there’s anything wrong with that! (~_^) and should we be surprised? a man sees a sexy woman and “thinks” (or reacts subconsciously) — “i’d like to get my hands on that|her!” so what? that doesn’t mean that all men always think of women as objects. just on one, very basic, biological level they do.

and, so, some women in the world behave accordingly. what’s the big deal?

these behaviors are just the surface expressions of the biological drives that work on us to get us to reproduce, that’s all.

p.s. – here’s some other research that found that women “dress to impress” when they’re ovulating.

controlling the mating game

via ferdinand, al** says (in a post about sexual age of consent):

“Modern societies are extremely hung up on sex for many reasons. Part of it comes from conservative religious values, but another part of the problem comes from leftist feminist constipative tendencies. Wherever you look, there are always those who want to force their way into your bedroom or hotel room.”

i got news for ya, al. ALL societies are extremely hung up on sex — including even non-human animal societies. and we’re not all hung up on sex “for many reasons” — we’re all hung up on sex for just one reason: because the whole point of life is to reproduce one’s genes (i.e. we’re just “machines for our genes“).

THIS is the reason — and the ONLY reason — why so many people want to “force their way into your bedroom or hotel room.” not because they ultimately care WHAT you do in your bedroom or hotel room (although they might say that, most people don’t know what they’re really about). no. they ultimately care WHO you’re doing in your bedroom or hotel room.

people are concerned about who their kids (most often their female kids) mate with because they’re concerned about how their genes are getting passed on.

they’re concerned that the people their kids (i.e. their genes) are mating with have “good” genes. they’re concerned that the people their kids (i.e. their genes) are mating with will take good care of any offspring (i.e. more of their genes). they’re concerned that all the time and effort and money they spent on raising their kids (i.e. their genes) won’t go to waste.

it’s just social control of reproduction (of genes), that’s all. and it happens in all sorts of societies in all sorts of ways.

**yes. i know that’s not al’s name. (~_^)
