i wasn't expecting much from that thread. i was more curious about the rationale of the atheism+ proponents. i got confirmation of what i feared....
the explanation is banal. 10 hour days at my "day job" + i sleep 6 hours + and have a daughter. not much on the margin. i devote way more time to moderation of comments than a typical blogger as it is, so it shows when i cut back.
Fallout from Razib banning or driving away quality commenters has reached even here.
i don't see what that has to do with anything. LW people say stupid things all the time.
addendum: i don't have much experience on this forum, but i am friends with people associated with the berkeley/bay area LW group. as i said, LW people say stupid things all the time. but,... (read more)
Aside from lactose tolerance (or more accurately, lactase persistence, as the "wild type" is "intolerance"), there are differences in enzyme quantities in saliva due to copy number variations between those populations which have a history of consuming carbohydrates and those which do not. There are also the various resistances to malaria. For multiple reasons, including history (e.g., malaria seems to have become endemic in the Mediterranean over the course of the Roman Empire), we know these are all new, anywhere from 6,000 to 500 years before the present. I can give other examples, but these are the most clear and distinct in the literature.
the video adds a lot if it is kerry and not will hosting free will. just sayin'.... ;-)
Hey, at least I got through over a solid year of posts without taking a vacation.
more a man than most!
eliezer,
hm. there's a lot to this...but let's just say that when it comes to psychology the residual of non-universality seems really important to focus on in the area of individual differences. specifically, it seems entirely possible that frequency dependent personality morphs abound; e.g., all the stuff about drd4 that i've been posting on my weblog. of course, this is single-locus, but i think it's just the locus of biggest effect. i suspect that what evolutionary psychology misses is that after you account for the substrate of human universals you've got personality morphs which are playing "games" with each other, and in particular there are a host of low frequency...

mike, for interdemic selection (one form of group selecction) there are models where altruists help the group grow but decrease in frequency over time, but then there is a disturbance where the groups reassort. at this point the altruists are at less an advantage and the groups without altruists go extinct, and the process begins anew as altruist frequencies decrease globally. see d.s. wilson's Unto Others for exposition (or an intro pop genetics book).
There are similar problems with getting Tit-for-Tat strategies to accumulate in repeated ecological Prisoner's Dilemma tests. If there isn't a subgroup population of sufficient size, it never comes to dominate the population.
Sometimes particles tunnel out of very deep potential wells, is all I can say.
lt's separate cultural and genetic dynamics here. on the fine scale level between group genetic variance is simply often weak tea to within group variance, and as eliezer implies 'cheater' strategies are pretty good. in meta-population dynamics when one group exterminates another is it usually total genocide? my reading of the ethnography suggests that usually men kill men and boys. they keep women who...

It's only comparatively recently that religion has been separate from nationhood or tribe, and its central tenets questioned. The fact that it's still around in a weakened state could simply be analogous to, say, our fight or flight mechanism. Or an appendix.
this is due to the fusion of religion with philosophy and the emerge of super-states which required super-religions. the first religious skeptics emerge in the record precisely when religion shifted from being informal implicit paganism toward a more formal structured system. e.g., the seeds of puranic hinduism, buddhism, jainism gave rise to the carvakas. the mystery religions were countered by lucretius and the epicureans. the religious enthusiasm...

if LW gave me dictatorial powers i would have nuked this sub-thread a long time ago, and saved a lot of people productive time they could have devoted to more edifying intellectual pursuits.
also, as a moderate diss, i don't delve deep into LW comments much anymore. but some of these remind now me of usenet in the 1990s. what i appreciate about the 'rationality' community in berkeley is that these are people who are interested in being smart, not seeming smart.
