> I guess my next question would be are genetically people that have genetic similarities more likely to have similar interests. If that is the case, it would lead to the politically uncomfortable question of different genders or ethnic groups being more likely to have particular interests.

Ethnic groups are defined by appearance and cultural history, not by genes. Many ethnic groups (e.g. African Americans) are extremely diverse genetically.

>by appearance not genes

I'm sorry, but genes clearly determine appearance.

People need to realize we are built on hardware that is hundreds of millions of years old. We share a similar hormonal dominance hierarchy system with fucking lobsters. You can't just say it's and expect these things to disappear. Tribalism was important for survival, trusting someone who didn't look like you could mean death and thus was selected for over long periods of time.

And then we became human and started not acting like lobsters. We have intellects, a sense of morality, and a will. Those allow us to drastically curtail what might otherwise be instinctive behaviors. I know there are some determinists who say that free will is illusory and we're as much slaves to our genetics and instincts as lobsters are. But it certainly seems as if, in practice, tribalism (at least the clear-cut…

I'm not so sure, as it seems anti-tribalism can become it's own tribe.

Genes, along with other factors, contribute to appearance, but it is possible to be (for a pair of humans) relatively close in appearance and generically dissimilar, or vice versa.

Genetic similarity and appearance similarity aren't the same thing.

Population structure is controlled through the use of the structure as a co-factor in the analyses. They use a principal component analysis on the genotypes to estimate the structure, and then use the first few principal components (PCs) as cofactors in the analyses. So if the European population they used consisted of half English and half French participants, then the first PC would likely divide the two. So if Bri…

Do you believe these findings though? (original article: http://www.pnas.org/content/111/Supplement_3/10796.full ) To me there are a few things worth highlighting, that are at least tangentially relevant: 1. This article was a PNAS Direct Submission. PNAS Direct Submission, a privilege typically reserved for members of the National Academy of Sciences, is like using trump-card to basically skip peer review. Since NAS…

You seem to not like the result of the study and making non-arguments to try to discredit it.

"The opposite pattern held for genes related to immunity -- friends tended to be less similar at those parts of the genome."

It would have been more accurate to title this article "Friends Are Genetically Similar in Some Ways and Different in Others" but I guess that would not have been as edgy.

EDIT: The overall trend reported is that friends are more genetically similar than would be expected, as pointed out by user Real_S. Good title, after all.

How else am I supposed to interpret "is that really so bad?" besides justification?

You quoted me but I actually didn't say anything about race or genetics. My original response was to the parent which was claiming that "tribalism is avoidable" and I was arguing against that saying that humans will always self-segregate into tribes so it's unavoidable. Examples: - I had a friendship which originally started over shared nostalgia for a cantonese children show - I was excluded from a group because I d…

Hm, well, I don't know that I'd call those "tribes," and I (reasonably, I thought) interpreted "tribalism" to be ethnic or racial based on it appearing in a discussion of "Friends Are Genetically Similar."

Tribalism is sometimes used as a descriptor for general in-group/out-group behavior as well.

Urbanization doesn't necessarily regress the issues I'm talking about, especially since cities can still have their own neighborhood and block communities. Urbanization isn't unnatural and it agrees with our tribal instincts. Look at Tokyo: extremely high density with extremely small social unrest. Paris, now a collection of different tribes, can't say the same.

Is that the only thing that's different about Tokyo and Paris? Beijing is over 95% Han Chinese and yet I don't think things look as harmonious. On another note, I think Japan ends up with kind of a distorted picture since so much of the crime is associated with organized criminal groups with ties to legitimate business and government operating with a degree of openness that I think would surprise most Western observe…

>Is that the only thing that's different about Tokyo and Paris?

I'm not claiming that. I am claiming that multiculturalism plays a role, which many people refuse to acknowledge.

Yeah, of course that is true, but I was making what I thought was a reasonable reading in context. It seems like the OP is describing something more like groups of friends; you can't really be a member of multiple tribes, necessarily.

I don't think the role is as significant as you are claiming.
