Vitamin D: why evolution may matter

Mark of Denialism left a comment below re: Vitamin D deficiency:

I wouldn’t call that evidence thin biff. The role of vitamin D in tuberculosis was actually pretty well nailed by studies of immigrants in the UK which demonstrate that latent TB infections will reactivate in the sunless climate. The demonstration of the role of Vit D in making defensins seems the likely physiological explanation.
I am wary though of some of the more hyperbolic claims I’ve seen about vitamin D lately. It’s fascinating stuff, sure. But until replicated in RCT rather than epidemiologically I think it’s too early to recommend universal supplementation with a vitamin that does have a toxic syndrome. Many vitamins have appeared similarly astounding in such studies and the benefits failed to pan out. This is likely due to certain epidemiologic biases that tend to show people who actively take care of themselves (take supplements, exercise, etc.) are generally wealthier, and healthier

The Elders of Ron Paul

Ed and Mark are asking what’s up with Ron Paul and the Neo-Nazis? I think…it’s complicated. Colugo sketches out the general lay of the land pretty well, Ron Paul is a “paleo,” specifically a paleolibertarian. He derives his ideology from the Old Right, and promotes a personal bourgeoise ethic. Three points:
* Ron Paul’s intellectual mentor was a Jew, Murray Rothbard, and the greatest intellectual in his firmament was a Jew, Ludwig von Mises. If Ron Paul is a closet Neo-Nazi he is a strange sort indeed. I think we can dismiss the idea that Ron Paul is a closet white nationalist. In his spare time he tends to obsess over the Gold Standard monomaniacally. That’s his passion, not the race.
* But there are white nationalists in the broader “paleo” movement. That is, though they do not personally avow racialist views they also do not necessarily view it is illegitimate prima facie. Joe Sobran is a man who mixes these various streams in on person, a convert to anarcho-capitalism through the writings of Murray Rothbard, this former editor of National Review was purged for his anti-Israel stances during the early 1990s, and now flirts with white nationalism and Holocaust Revisionism. But this isn’t to show that all paleos are racialist, after all, the conservative Bob Taft Club is headed by an individual who is half-Korean and half-Jewish. But note that the same individual was interviewed (as a fellow traveler) on a Neo-Confederate radio show with a strong racialist and non-trivial anti-Semitic tinge (the show also interviewed David Duke and a host of other white nationalist luminaries). Most of you will also know of Ron Paul’s famous newsletter from the mid-1990s. I would be willing to bet that if Ron Paul did not write the text, he was probably aware of its general outline. Again, I think this is not evidence of a convinced and principled racialist, but it reflects a man who does not reject white nationalist viewpoints as a matter of course. This should not shock some of the more liberal readers of this weblog, after all, I suspect many of you would find some of the milder and more hinged critiques of Jewish and/or Zionist1 power in shaping American attitudes toward the Israeli-Arab conflict quite cogent. Just because someone is crazy doesn’t mean all their utterances are crazy. That is, in my assessment, Ron Paul’s attitude toward white nationalists (many of you would probably hold though that the views Paul accepts as non-crazy from white nationalists are crazy!).

Get thee to the semiotics department!

Steve points me to this George Johnson piece. Regular readers of this weblog know that we have had our differences with Jared Diamond. That being said, Diamond’s ideas are clear & distinct, you can actually understand (and disagree) with what he is trying to say. A few years back when the Savage Minds weblog was getting into it with Diamond’s defenders on the blogosphere one of the main issues seemed to be that it was hard to parse exactly what problem the cultural anthropologists had with Diamond besides the obvious perception from their camp that he was a racist (the post above GNXP authored was actually used to support that contention!). There are two distinct issues at work here, one general and the other rather specific.

First, some anthropologists, generally of a cultural or social bent, have become enamored of the same fashions which are rife within literary scholarship. One could use a catchall term like “Post Modernism” to describe these tendencies, though that’s oversimplifying. Roughly, the flight to relativism and the acknowledgment of the subjectivity of scientific methods inevitable in the human sciences have been taken almost to a reductio ad absurdum by cultural anthropologists. The broader dynamic was one reason that Stanford’s anthropology department was split in two, separating those who viewed their discipline as a science and those who took a more humanistic tack. In the latter case one could say that the goal is interpretation, not analysis, fine grained description as opposed to smoking out systematic general truths. The trend toward very specific description and disinclination to place the local in the general context leads to intellectual myopia. Imagine a riverine system where you have two groups of scholars. One group uses a method where a researcher takes a very deep core sample at one location. They examine that core and perfectly characterize the sedimentary structure on that location. The other group engages in a broad study of shallow cores and visual inspection across the whole system; they lack detailed specific knowledge but are attempting to sketch out the general dynamics of the system. Obviously there are strengths and weaknesses to both methods, and your needs and goals need to be kept in mind. The generalists will no doubt elide specific details, while those who pour over a specific deep core will accept a trade off between their detailed local knowledge and the broader framework.

And so it is when “thick description” partisans square off against general system-builders. General system-builders will usually be wrong, most theories do not stand up to the test of time, and the vast majority of hypotheses are false. Additionally, they will ignore local detail and over generalize so as to remove outliers from their model. This is not a bug, but a feature! Cultural anthropologists who jump upon inaccuracies in inferred detail (that is, they contend that the hypothesis does not hold in the case of their studied culture) seem to not consider that system-builders by the nature of their topic of study in the human sciences will offer up statistical truths, as opposed to apodictic ones. I suspect that this confusion is in part due to the fact that many cultural anthropologists seceded from the nation of social science just as statistical techniques became ubiquitous in validating assertions of truth. The problem with American cultural anthropology is not that it is not true, but that it can never be wrong! Where as they see the naked & plain error within Diamond’s work as a mark of its folly, in truth it is simply the beauty of science that falsities are exposed for what they are. On occassion marginal deviations along the edges of a theoretical construct are even cleaned up in future iterations. Imagine that, scientific progress! Instead of rebutting Diamond’s thesis with their own general system cultural anthropologists reject the whole project in its entirety. In the stinginess of their vision I must admit that they remind me of Michael Behe, who implies that what is not known or understood with any level of clarity in the present shall be incomprehensible in a naturalistic sense indefinitely by its very nature.

As for the specific problem with cultural anthropology, it is encapsulated in this quote from the piece above, “Diamond in effect argues that no one is to blame,” said Deborah B. Gewertz, an anthropologist at Amherst College. “The haves are not to be blamed for the condition of the have-nots.” Does the ethologist blame the sick Wildebeest which is killed by the lion? Does the conversation biologist blame the Dingo for likely having driven the Tasmanian Tiger to extinction? Or does the conservation biologist absolve the Dingo of blame because the arrival of Europeans would likely have heralded the Tiger’s doom in any case? Does the particle physicist give thanks to CP violation for allowing the flourishing of our civilization? And so on. These are ridiculous queries because even though a wildlife biologist might, as a human, harbor an affection for the animals of their study, in the end they are animals to study. This sort of objectivity, or at least the attempt, seems anathema to some anthropologists who see themselves as activists and actors who are deeply engaged with the material basis of their scholarship. Despite the cultural anthropologists’ rejection of general inferences from data they seem to have no great qualms in making general normative assertions derived from their own axiomatic value system.

As human beings we are likely cognitively biased toward viewing our own species as special. This crops up in taxonomy, where Carl Linnaeus placed us within our own genus though subsequent cladistic systematics implies that we form a monophyletic lineage with the other great apes. The Great Chain of Being suffused early evolutionary thinking, and even after our descent from pre-human primates was acknowledged our morphogenesis was conceived in a teleological light, we were the crown jewel of biological processes. The Modern Synthesis banished this sort of teleological thinking from evolutionary biology, killing the batch of orthogenetic theories which reigned supreme circa 1900. In the first half of the 20th century anthropology was an ideological discipline which also expressed a teleology, the evolution of human societies expressed a trend which culminated with the Europeans, anthropologists were an arm of the supremacist Zeitgeist in the West. The Nazi abomination showed anthropologists that such activism was illegitimate. But instead of turning from activism and ideological pursuits anthropology simply inverted itself, it became a handmaid of the counter-cultural elite, pushing relativism and lack of positive assertion as virtues except in their rejection of the West and a general suspicion of the culture of European man. The disaster of racial science as the handmaid to the racial state did not draw anthropologists to the conclusion that aspiration toward objectivity should be their goal; rather, they switched sides en masse and hitched their wagon to the cultural winners in the academy.

Though this secured their place in the humanities departments, it also made them a laughing stock in the eyes of other scientists. Here was what L. L. Cavalli-Sforza stated when I interviewed him:

I entirely agree that the average quality of anthropological research, especially of the cultural type, is kept extremely low by lack of statistical knowledge and of hypothetical deductive methodology. At the moment there is no indication that the majority of cultural anthropologists accept science – the most vocal of them still choose to deny that anthropology is science. They are certainly correct for what regards most of their work.

Anyone who is familiar with Cavalli-Sforza knows he is a humanist; he has a passion for humanity and wishes to understand our species to the best of his ability. It is clear that he does not perceive that cultural anthropologists share the same passion for understanding, as opposed to their own admittedly subjective interpretations. The evolutionary geneticist James F. Crow stated upon controversial research on human evolution & behavior:

I hope that such questions can be approached with the same objectivity as that when we study inheritance of bristle number in Drosophila, but I don’t expect it soon. There are too many strongly held opinions. I thought Lahn had a clever idea in thinking that the normal alleles of head-reducing mutants might be responsible for evolution of larger heads in human ancestry. Likewise, I think that Cochran et al. are fully entitled to consider the reasons for Jewish intelligence and I found their arguments interesting. In my view it is wrong to say that research in this area — assuming it is well done — is out of order. I feel srongly that we should not discourage a line of research because someone might not like a possible outcome.

Is man but a fly? Why not? I can give you my ethical and moral rationales for why man is not a fly in an ontological sense, but scientifically we are of the same essence, the same atomic units, many of the same genetic switches, and so forth. The insight that man is an animal was one Charles Darwin popularized in the 19th century, but cultural anthropologists reject this truth because they reject all truths except the ones they feel privileged to assert from their perches as conscious and enlightened folk (but is not being enlightened itself an expression of a hegemonic mindset?). It is difficult to take a system of scholarship which seems to promote obscurity and subjectivity as goods seriously. Study of human societies is more difficult than breaking down a molecular genetic pathway; but that is no excuse to give up the quest for clarity, precision and prediction. We’re a complex species, and there are many contingent variables which clog up any system. But I see no reason that that justifies reading societies like a work of fiction; presenting arguments as clever word games which rise and fall based on prose opacity and the fads of the day. Cultural anthropology’s adherence to critique is not the problem, criticism is a necessary antidote to sloppy thinking, rather it is its promotion of critique as the sin qua non of the discipline and insulation from falsification by saying nothing positive at all. They should leave criticisms of Jard Diamond’s grand system of the world to those who actually believe that such activities are not scandalous in the first place!

Virus problems with gnxp?

Received this email:

It appears your website has been compromised. When visiting https://gnxp.com (as opposed to regular http) Firefox prompted me with a message that the security certificate for snakeoil.dom has expired. After some googling I found out it is likely an authentication certificate for a virus.

I didn’t have the same problem. I’m in a hurry, but I assume this is a client side issue? There isn’t an SSL certificate for this website.

The Ascetic Style in American Atheism

On this Sunday’s Weekend Edition on NPR there was a piece titled Removing Religion from the Holidays a Tall Order. Much of the story focuses upon Greg Epstein, a Humanist Chaplain at Harvard, and his attempt to forge a new more humane secular cultural sensibility which does not reject all that that is religious because it is religious. On the other side there are others who say that the trends Epstein is promoting “sounds like religion and smells like religion.” As I noted in earlier, these sorts of issues are not so cut & dried, and common sense is often a better guide to the “right decision” than inferences from axiomatic doctrine. Shouldn’t we be as concerned about if it smells good as the provenance of the smell?
I’m assuming that on this day many of your are celebrating Christmas right now. This was written earlier and scheduled to post now, so I am eating, drinking and socializing. Many of you will likely read this a day or two later. As a culture we exhibit a synchronicity in our behaviors and rituals, we are not creatures who engage in social Brownian motion. This is not a matter of right or wrong, it is a matter of what we are.

Autism & yawning

Absence of contagious yawning in children with autism spectrum disorder:

This study is the first to report the disturbance of contagious yawning in individuals with autism spectrum disorder (ASD). Twenty-four children with ASD as well as 25 age-matched typically developing (TD) children observed video clips of either yawning or control mouth movements. Yawning video clips elicited more yawns in TD children than in children with ASD, but the frequency of yawns did not differ between groups when they observed control video clips. Moreover, TD children yawned more during or after the yawn video clips than the control video clips, but the type of video clips did not affect the amount of yawning in children with ASD. Current results suggest that contagious yawning is impaired in ASD, which may relate to their impairment in empathy. It supports the claim that contagious yawning is based on the capacity for empathy.

Someone should do behavioral economics studies on groups of autistic individuals. Would surely validate the mid-20th century microeconomic consensus.

Indigenous European paganism

Found out something interesting today. In the Russian republic of Mari El there exists an indigenous pagan tradition which is not a reconstruction. That is, the pagans of Mari El trace their practice in an unbroken line back to their ancestors, as the Christianization during the period of Ivan the Terrible (the 16th century) was only partial. Other European pagans are by necessity neo- and must reconstruct their system of beliefs and rituals from extant records and folk traditions. The Saami were pagan until the 18th century, and with that I had assumed that all pre-Christian traditions had died. This falsifies that, though some might quibble that the European nature of the cult of Mari El is a matter of geographical technicality (that is, Orthodox Russia’s status as a European nation are somewhat ambiguous to begin with). Here is an article about the pagan revival:

Unlike in western Europe, paganism among the Mari constitutes an unbroken tradition rather than a New Age construction. Mari anthropologist Nikandr Popov points out that pagan prayer meetings were permitted by decree during the Second World War – with collections being made for the front – and survived subsequent Soviet attempts to suppress them. Today Mari pagans gather together for approximately 20 festivals annually, at which they offer animal sacrifices in specially designated sacred groves. There are now 360 such groves in the republic and around 120 karts (pagan priests), according to one of the claimants to the title of head kart, Aleksei Yakimov.

We forget that Russia is one of the most ethnically diverse nations in the world. Much of this is simply due to the fact that the settlement of Siberia by Slavs is a relatively recent and half-measured affair, and the indigenous tribes have no been absorbed into the national identity. But even in European Russia to the west of the Urals the Slavic speaking farmers who expanded into the forests of the hunting & fishing peoples to the north and east did not sweep away all before them. In contrast such relics are rare in central and western Europe; one case may be the Sorbs in eastern Germany, who are what remains of the Slavic people who once dominated the lands on the eastern side of the Elbe. Another are the Vlachs of the Balkans, Romance speaking herders who are probably the remains of the peasants of Pannonia & Illyircum who once sent Emperors to Rome (e.g., Diocletian). In this case Russia is more like China or India than the rest of Europe. The dominant cultural dispensation is numerically preponderant and can assert hegemony within the bounds of the geographic extent of the civilization, but numerous residual peoples with distinct identities remain “undigested.”

Jamie Lynn Spears: it runs in the family?

Hometown Reacts: Residents Respond To Pregnancy News in relation to Jamie Lynn Spears & Casey Aldridge’s impending parenthood:

But we did manage to talk to a few locals, who, quite honestly, weren’t too shocked to learn that Britney’s little sister was pregnant, either because teen pregnancies aren’t all that uncommon in Kentwood, or because, after all, she is Britney’s little sister.
“They tried to keep it secret, I don’t know why. In Kentwood, everything gets out. You got kids who are 13 or 14 and pregnant in Kentwood, we’re about used to it around here,” Donald Church said. “But it seems like a big deal around here. … A lot of people can’t believe it. I used to work with her dad, and I couldn’t believe it. You know, little Jamie … it’s kind of freaky.”
“I heard about it on the radio, they were talking about it. It’s real popular down there. Everybody knows about them,” Raynard Norman laughed. “It’s embarrassing, kind of. If it’s not her, it’s Britney, so at least it’s not Britney this time. But I’m not surprised, not really. … Nobody’s surprised because it’s not uncommon with her family. Next time, use a condom.”

In The Genetical Theory of Natural Selection R.A. Fisher offered up a reason why long term decreased fertility was never going to be an evolutionary problem for the human race: if any fertility was in any way heritable the proportion of the population which exhibited traits resulting in relative fecundity would slowly increase and replace those disinclined toward reproduction. Evolution is often characterized as “Survival of the Fittest.” First, that is actually simply even metaphorically corrected in regards to evolution driven by natural selection. But second, it is probably more accurate to say it is survival of the fertile. Physiological fitness may not correlate with reproductive output. Remember antagonistic pleiotropy?
Note: It could of course be cultural heritability. Fisher elucidates that argument as well, arguing that pro-natalist religions will promote the increase of their flock. In Rodney Stark’s The Rise of Christianity he makes the argument that the sects opposition to infanticide and communal support networks were critical in allowing it to marginalize paganism in part through procreation.
