holy toledo! two week’s worth of links! happy friday! (^_^)
John Derbyshire On Nicholas Wade’s A TROUBLESOME INHERITANCE – A Small, But Significant, Step For Race Realism – “Wade raises high the banner of race realism and charges head-on into the massed ranks of the SSSM. He states his major premise up front, on page two: ‘New analyses of the human genome have established that human evolution has been recent, copious, and regional.’ Those last four words are repeated at intervals throughout the narrative. They are, as it were, the keynote of the book; Wade returns to them many times to anchor his observations — and some speculations — on the history and development of human societies.” (my emphasis there – h.chick)
henry harpending on science – “[T]his is perhaps at the heart of the slander of the so called hbd-crew that circulates. Most of us are really interested, in our hearts, in theory and models. This is the way that most of science works…. You state somewhere that the hbd crew is obsessed with IQ. Seems so, but wait! IQ is literally the only thing that can be reliably measured of a whole constellation of interesting traits. It really does work in the sense of telling one whom to hire or whom to admit to graduate school. You also speak of what we ‘believe’ but the whole fun of science is falsifying hypotheses, not believing them. I would give my eye teeth (if I had them) to come up with something besides IQ to look at.” (my emphasis again – h.chick)
Digging For Gold: Study Says Your Race Determines Your Earwax Scent – h/t hbd bibliography!
Austronesians Out of the Cauldron – “…the emergence of Austronesians. Linguistics and archaeology already were rather clear on the pattern of expansion, and when. But now an ancient DNA remain from off the coast of Fujian dated to ~8,000 years ago solidifies in totality the where and when. This is not an argument anymore.” – from razib.
New Diet, Sexual Attraction May Have Spurred Europeans’ Lighter Skin – “[A] new study of ancient DNA concludes that European skin color has continued to change over the past 5000 years, suggesting that additional factors, including diet and sexual attraction, may also be at play.” – see also: Natural selection has altered the appearance of Europeans over the past 5,000 years.
It made their brown eyes blue… – “A recent report in PNAS shows the inhabitants of the Ukraine and its environs had much darker hair, skin, and eyes back in the Bronze Age and earlier.” – from greg cochran.
Did Europeans become white in historic times? – from peter frost.
Pause Is Seen in a Continent’s Peopling – “Using a new method for exploring ancient relationships among languages, linguists have found evidence further illuminating the peopling of North America about 14,000 years ago. Their findings follow a recent proposal that the ancestors of Native Americans were marooned for some 15,000 years on a now sunken plain before they reached North America.”
The place of the Armenian language in the Indo-European family – “A very interesting talk at the Library of Congress making a good case for a Greek-Phrygian-Armenian clade within the Indo-European family.” – from dienekes.
One Million Brits ‘Descended from Vikings” DNA Study Claims – “Around one million Britons, or one in 33 men across the UK, can claim direct descent from Vikings, according to a new DNA study. Men from the far north of Scotland were most likely to provide a direct match with almost a third (29.2%) of the men from the Shetland Islands testing positive for Viking blood.” – h/t ed west!
Genetic Architectures – “The point is that the genetic architecture of a quantitative trait does not have to be the same in different populations of the same species. For example, I have the impression that height is not as highly polygenic in Pygmies as it is most other human populations. There’s a particular region on chromosome 3 that seems to influence height- you don’t see such a concentration in Europeans.” – another from greg cochran.
Molecular genetic contributions to socioeconomic status and intelligence – h/t billaire! who tweeted: “21% of the var. in education level, 18% of SES, 29% of cognitive ability explained by COMMON SNPs in Scottish sample.”
Study finds genetic link between height and IQ – “A team of researchers at Edinburgh University in Scotland has found a correlation between genes associated with height and those associated with intelligence. In their paper published in the journal Behavior Genetics, the group describes how they studied the DNA of 6,815 unrelated people and discovered what they describe as a direct correlation between height and intelligence—taller people are smarter, they say.”
HVGIQ: Puerto Rico – from jason malloy.

Evidence for the general factor of personality as social-effectiveness
Intelligent people are more likely to trust others – “Intelligent people are more likely to trust others, while those who score lower on measures of intelligence are less likely to do so, says a new study. Researchers based their finding on an analysis of the General Social Survey, a nationally representative public opinion survey carried out in the United States every one to two years.” – h/t mr. mangan, esq!
Openness to experience and aesthetic chills: Links to heart rate sympathetic activity – “These results suggest links between openness to experience and sympathetic nervous system activity explaining, at least in part, relationships of openness to such traits as aesthetic chills.” – h/t stuart ritchie!
Psychological refractory period in introverts and extraverts – “Evidence for faster stimulus analysis in extraverts compared to introverts.”
‘Free to Be’ Boys and Girls: 40 Years After the Failed Gender Revolution – “1974′s ‘Free to Be…You and Me’ feels like an eternity ago. And, amazingly, kids and adults have yet to morph into mutually respectful, non-gendered human persons.” – from christina hoff sommers.
Personality Regions: The Friendly Midwest, the Left Coast and the Wicked (Possibly Irish) Witch of the Northeast – from staffan.
Want Success? Choose the Right Parents – “Gregory Clark’s startling new book, ‘The Son Also Rises,’ asks you to rethink everything you thought you knew about social mobility. His research, if it’s correct, isn’t good news. It says that socio-economic status is mostly a matter of nature not nurture, and suggests that trying to help the disadvantaged move up won’t make much difference.” – h/t alice teller! – see also: Social mobility: Have and have not – “Mr Clark follows his logic to an unexpectedly egalitarian end. Redistribution is sensible, he argues, not in order to boost mobility but because mobility is intractably low. The cream will rise regardless, and so paying extraordinary salaries to capable workers is unnecessary. If high rates of mobility are used to excuse or justify inequality, he suggests, then the reality of low mobility implies something quite different: t hat great inequality serves little purpose and redistributing income from the rich to the poor might raise overall welfare at little economic cost. This makes for uncomfortable reading for those of all ideological persuasions.”
Why HBD – “As I have tired to explain in my earlier post, Environmental Hereditarianism, the behavioral and physical traits of people are environmentally context-dependent. The broad environmental context regulates the expression of the genes. There is *not* a dichotomy between genes and ‘environment’. Nor could there be one – we are always ‘with’ both. The broad environment includes geography, climate, technology, and prevailing social landscape (otherwise known as ‘culture’). When the social-technological-geographic landscape changes, you can have broad behavioral change all without genetic change. This explains secular changes that occur too quickly to be a result of evolution, such as the sexual revolution, the modern rise in irreligiosity, the increase in the obesity rate, etc.” – from jayman.
Key connection – “Biologists zero in on role of plasticity in evolution. For more than a century, scientists have suggested that the best way to settle the debate about how phenotypic plasticity — the way an organism changes in response to environment — may be connected to evolution would be to identify a single mechanism that controls both. Harvard researchers say they have discovered just such a mechanism in insulin signaling in fruit flies. Cassandra Extavour, an associate professor of organismic and evolutionary biology, and grad student Delbert André Green II were able to show that a single molecular pathway plays a role in both heritable changes in the flies’ number of ovarioles — egg-producing compartments in the ovaries — and in how they react to their environments by shutting down some ovarioles. The study is described in a paper published this month in the Proceedings of the Royal Society B. ‘This is the first example, to my knowledge, that shows this link — between heritability and plasticity — being controlled by the same mechanism,’ Extavour said. ‘What we’ve done with this paper is show that an important trait that controls how many offspring a fruit fly will have exhibits both heritable variation and phenotypic plasticity, and that both are controlled by insulin signaling.’” – h/t steven pinker!
Morality and the Lament of the Liberal Atheists – “Moral relativism is the ground state of living things. It doesn’t work for a social species like ours. If every one of us tried to monopolize all the available resources within his grasp at the cost of everyone else, the chances that any given individual would survive and reproduce would be drastically reduced. Therefore, morality. It exists because, from an evolutionary perspective, it works. It will continue to function just as it always has, even if 100,000 philosophers shout at the top of their lungs that it’s irrational. Of course it is, but it doesn’t matter. We will continue to perceive the good and evil that seem so real to our imaginations as absolutes. It is our nature to do so….” – from helian

Hypothesis on Why Northwest Europe Began Outbreeding – “It could just be coincidence that the outbreeding areas that coincide with other positive hajnal line traits were also lands conquered by men from tribes with the traditions of Germanic kingship. These kings were illiterate barbarians seeking legitimacy and thinking long term at the security of their line ruling…. This is a hypothesis, but the position these rulers were in was one of new conquerors in foreign lands. They needed to create and encourage loyalty in the natives as well as find a way to secure their individual line as king in a manner that was different from what their people, the conquerors, were accustomed to. The Church, an institution eager for power in a new area as well, offered an opportunity to import a political infrastructure and change the social make up of their new lands. Even moreso in England than the rest of core Europe, the Church and the elite’s motivations and goals overlapped perfectly. Christianity was new to them and new to the Britains, but as conversions mounted, it was a shared trait amongst them all. That shared identity was the warrior-chiefs’ way to have rule and kingship legitimized. That shared identity made the natives and newcomers men of Kent or East Anglia, later England, and not of the clan.” – good stuff from son of brock landers!

Do Women’s Mate Preferences Change Across the Ovulatory Cycle? A Meta-Analytic Review – answer: yes. – see also: Intersexual conflict across women’s ovulatory cycle – “Results indicate that (a) men are particularly self-assertive toward partners when their partners are fertile; (b) similarly, women are especially self-assertive toward partners when they are fertile; (c) women report engaging in more behaviors that resist male vigilance and mate-guarding when they are fertile, especially in ways that are unobservable to male partners; (d) these effects are especially strong when women themselves report greater attraction to men other than partners when they are fertile, compared to the luteal phase.” – h/t robert burriss!
Study finds less cooperation among women than among men where hierarchy is involved – “‘When I studied young children, I noticed that boys were typically interacting in groups, and girls tended to focus on one-on-one relationships,’ said Benenson, the study’s lead author, who explored similar questions in her book Warriors and Worriers. ‘There is even evidence that these differences exist in six-month-olds – but you can see it with the naked eye by about five or six years old, where boys form these large, loose groups, and girls tend to pair off into more intense, close friendships.’ What makes those differences particularly provocative, Benenson said, is that chimpanzees organize their relationships in nearly identical ways. ‘Chimpanzee males usually have another individual they’re very close with, and they may constantly battle for dominance, but they also have a larger, loose group of allies,’ Benenson said. ‘When it comes to defeating other groups, everybody bands together. I would argue that females don’t have that biological inclination, and they don’t have the practice.’”

Personality Traits and Body Mass Index in a Korean Population – “Compared with the normal weight groups, overweight and obese men scored higher on openness to experience and lower on conscientiousness. Overweight and obese women scored lower on neuroticism and openness to experience and higher on agreeableness. Extraversion was positively associated with BMI in men (β = 0.032, P<0.05). BMI and waist circumference were significantly increased in individuals who were less dutiful. In women, neuroticism was inversely associated with BMI (β = −0.026, P<0.05). Openness to experience was negatively, and agreeableness was positively, associated with BMI (openness to experience: β = −0.072, agreeableness β = 0.068) and waist circumference (openness to experience: β = −0.202, agreeableness: β = 0.227) (P<0.05).”

Is Ed Houben Europe’s most virile man? – “Ed Houben has an unusual pastime. He has slept with scores of women who seek him out for his legendary powers of insemination…. Ed Houben has come to see his daughter for the first time. He talks gently to the six-week-old baby, and little Madita looks up at him. She is, he says, his 98th child.”
The Costume of Shangri-La: Thoughts on White Privilege, Cultural Appropriation, and Anti-Asian Racism – it’s worth quoting the whole abstract: “This piece poses cultural appropriation as an undertheorized aspect of white privilege in White Privilege Studies. By way of narrative exploration, it asserts that a paucity of scholarship on Orientalism and anti-Asian racism has created a gap in White Privilege Studies that curbs its radical transformative potential. It argues for the value of a structural and historically focused lens for understanding the issue of cultural appropriation, and extends questions of culture and race relations beyond the borders of the United States. It also explores the complex ways that interracial and transnational relationships can influence white racial identity, and illustrates the disruptive potential that queer interracial relationships can offer to dominant historical patterns of white behavior.” – (~_^) h/t ben southwood!
