Your Ancestors, Your Fate“The notion of genetic transmission of ‘social competence’ — some mysterious mix of drive and ability — may unsettle us. But studies of adoption, in some ways the most dramatic of social interventions, support this view. A number of studies of adopted children in the United States and Nordic countries show convincingly that their life chances are more strongly predicted from their biological parents than their adoptive families. In America, for example, the I.Q. of adopted children correlates with their adoptive parents’ when they are young, but the correlation is close to zero by adulthood. There is a low correlation between the incomes and educational attainment of adopted children and those of their adoptive parents. These studies, along with studies of correlations across various types of siblings (identical twins, fraternal twins, half siblings) suggest that genetics is the main carrier of social status.” – from gregory clark. see also The Son Also Rises: Surnames and the History of Social Mobility.

Reductionism! Determinism! Straw-man-ism!” The main problem, it seems to me, is a fundamental misunderstanding of what genetics as a science studies and how it relates to the function of complex systems. The following statements are not contradictory: 1. The function of a complex system emerges from the complex and dynamic interactions between all of the components of the system, in a context- and experience-dependent manner. 2. Variation in single components of the system (or in multiple components) can affect how it functions. Geneticists investigate the second question. Showing that variation in Gene X affects the behaviour or outcome of a system is not the same as saying that Gene X fully determines that behaviour or fully accounts for the entire system. Gene X is just a piece of DNA sitting in a cell somewhere – it doesn’t do anything by itself. But a *difference* in Gene X can account for a *difference* in how the system works. – from kevin mitchell.

There’s nothing wrong with looking for ‘gay genes’“The Left loves to tell the Right that it’s anti-science, pointing (not without reason) to the correlation between conservative beliefs and a failure to come to terms with the scientific facts of evolution and human-caused climate change. But there’s a subtler tendency on the Left; a fear of research into human nature, in case the findings are in some way politically uncomfortable.”

Scientists unlock a ‘microbial Pompeii’“An international team of researchers have discovered a ‘microbial Pompeii’ preserved on the teeth of skeletons around 1,000 years old. The key to the discovery is the dental calculus (plaque) which preserves bacteria and microscopic particles of food on the surfaces of teeth, effectively creating a mineral tomb for microbiomes.”

The effect of paternal age on offspring intelligence and personality when controlling for paternal trait level [pdf] – “We examined the effect of father’s age at birth on offspring intelligence, head circumference and personality traits. Using the Minnesota Twin Family Study sample we tested paternal age effects while controlling for parents’ trait levels measured with the same precision as offspring’s. From evolutionary genetic considerations we predicted a negative effect of paternal age on offspring intelligence, but not on other traits. Controlling for parental intelligence (IQ) had the effect of turning an initially positive association non-significantly negative. We found paternal age effects on offspring IQ and Multidimensional Personality Questionnaire Absorption, but they were not robustly significant, nor replicable with additional covariates. No other noteworthy effects were found.” – from lars penke.

Reversed hierarchy in the brain for general and specific cognitive abilities: A morphometric analysis“Here, we analyze gray matter with three morphometric indices (volume, cortical surface area, and cortical thickness) at three levels of the intelligence hierarchy (tests, first-order factors, and a higher-order general factor, g)…. The key finding reveals substantial variability in gray matter correlates at the test level, which is substantially reduced for the first-order and the higher-order factors. This supports a reversed hierarchy in the brain with respect to cognitive abilities at different psychometric levels: the greater the generality, the smaller the number of relevant gray matter clusters accounting for individual differences in intelligent performance.” – h/t ben southwood!

A nice bunch of flowers“The general factor of intelligence is strongest at lower levels of intelligence. It may be a case of ‘All neurones to the pump’. When abilities are low, most problems are difficult. In such cases, all resources have to be thrown at the problem. When abilities are higher there is more spare capacity for differentiation of abilities. Brighter persons have a lower proportion of their abilities accounted for by a common factor, even though the have higher absolute abilities.” – from dr. james thompson.

Four Lame Responses to Sam Harris’ Moral Landscape Challenge“Moral emotions, like every other evolved trait, exist because their presence increased the probability that the genes responsible for the existence of those traits would survive and reproduce. Moral emotions, and the associated illusions of the existence of Good and Evil as things in themselves, exist as subjective impressions in the minds of individuals.” – from helian.

Free will beliefs and motivation to punish“In a paper forthcoming in the Journal of Personality and Social Psychology, Cory J. Clark and co-authors provide evidence that widespread belief in the existence of free will is bolstered by a fundamental desire to punish wrongdoers…. As Clark et al. put it, ‘There seems little doubt that the subjective experience of choosing and acting supports people’s belief in free will, but our findings suggest another powerful motivating factor: the human impulse to blame and punish. People believe in free will – at least in part – because they wish to affirm that people who do immoral things could have and should have acted differently’.”

Creativity and personality in classical, jazz and folk musicians“[J]azz musicians are more frequently engaged in extracurricular musical activities, and also complete a higher number of creative musical achievements. Additionally, jazz musicians show higher ideational creativity as measured by divergent thinking tasks, and tend to be more open to new experiences than classical musicians. This study provides first empirical evidence that jazz musicians show particularly high creativity with respect to domain-specific musical accomplishments but also in terms of domain-general indicators of divergent thinking ability that may be relevant for musical improvisation.” – h/t mary louise cowan!

Migration and interaction in a contact zone: mtDNA variation among Bantu-speakers in southern Africa“In this study, we analyze complete mtDNA genome sequences from over 900 Bantu-speaking individuals from Angola, Zambia, Namibia, and Botswana to investigate the demographic processes at play during the last stages of the Bantu expansion. Our results show that most of these Bantu-speaking populations are genetically very homogenous, with no genetic division between speakers of Eastern and Western Bantu languages. Most of the mtDNA diversity in our dataset is due to different degrees of admixture with autochthonous populations.”

Silver Blaze“[I]n most parts of Europe, it looks as if modern populations inherited the three EEF/WHG/ANE groups (Levantine farmers, West Hunters and Sibermen) via only two proximate ancestral populations. Europe at the time was almost entirely occupied by Sardinian-like farmers – then another population moved in, one that had about 3 times as much West Hunter as Sibermen.” – from greg cochran.

Replacement or continuity?“Ancient DNA seems to promise a clearer picture because the only source of uncertainty is the age of the skeletal material. Unfortunately, this new method is more sensitive to uncertainty from another source: natural selection. Late hunter-gatherers and early farmers had to adapt to different environments. There certainly was a genetic divide between the two, but did it result from differences in origin or from differences in natural selection?” – from peter frost.

The parasite that escaped out of Africa: Tracing origins of malaria parasite“An international team has traced the origin of the second-worst malaria parasite of humans to Africa. The closest genetic relatives of human *Plasmodium vivax* were found only in Asian macaques, leading researchers to believe that *P. vivax* originated in Asia. This study overturns that, finding that wild-living apes in central Africa are widely infected with parasites that, genetically, are nearly identical to human *P. vivax*.” – h/t hbd bibliography!

i have my OWN page @(ir)rational wiki now! i feel like i’ve really arrived (~_^):

“Hbdchick is a HBD blogger who attempts to give scientific racism credibility by presenting herself as an innocent bookworm fascinated with human variation.

“Like other bigots who now try to rebrand racialist and racist ideologies online through HBD or ‘race realism’ blogs and forums, Hbdchick describes herself a geek who became a ‘HBDer’ after reading books on ‘Eskimos and Indians, that sort of thing – and I was absolutely transfixed by them!’. Sounds innocent right? Somehow though books on Eskimos and Indians leads to the view there are racial differences in IQ, that black people have smaller brains and other 19th century pseudo-science which fills Hbdchick’s blog. Hbdchick also links to other ‘HBD’ sites including an assortment of neo-nazis, racists and internet-kooks (e.g. ‘Racial Reality’ the founder of Anthroscape, Bonesandbehaviours set up by a Holocaust-denier, Chris Brand, Steve Sailer and Forumbiodiversity).”

yes. ’cause posts on racial differences in iq and the fact that black people have smaller brains than other popuations (on average, btw) absolutely FILL my blog.

let’s look at the stats. i’ve posted a total of 1,672 posts. 199 of them have been “saturday star wars” posts, so they’re not hbd-related. that leaves a total of 1,473 serious posts (not that my saturday star wars posts aren’t serious!).

checking through my posts tagged with “iq” — there are 133 of them, btw — i find that there is a grand total of exactly 1 — o n e — which relates to racial differences in iq: andrew sullivan talks sense on iq.

yeah. my blog is absolutely LOADED with discussions on racial differences in iq! not that there’d be anything wrong with that. but SOMEbody over at rational wiki maybe ought to actually READ my blog!

guess they also missed my recent post: you and me and hbd.

(note: comments do not require an email. but please do read the blog first!)

from a study published in 2011 [pdf]:

“We show how the prevailing majority opinion in a population can be rapidly reversed by a small fraction p of randomly distributed *committed* agents who consistently proselytize the opposing opinion and are immune to influence. Specifically, we show that when the committed fraction grows beyond a critical value pc ≈ 10%, there is a dramatic decrease in the time, Tc, taken for the entire population to adopt the committed opinion.”

that in itself is interesting when thinking about how to spread the good news about human biodiversity, sociobiology, etc., etc. — apparently there needs to be a committed (no, not THAT sort of committed) ten percent of us if we’re to have any hope of the majority accepting the realities of hbd. of course, being ten percent doesn’t guarantee that the majority will run with the idea, just that that is A minimum requirement — if these researchers have got it right.

but that’s not what i want to look at right now. what i want to know is: how much longer? how much loooonger do we have to put up with political correctness?! or as jayman asked: “when does it all break?”

there was an interesting chart published online in connection with that 2011 paper showing the trajectory of the spread of a new idea once it starts to be accepted by the majority (again, once ten percent of the population had already accepted it AND were committed proselytizers):

the ten percent

to me, that graphic — the insert (the line graph) — looks like it’s just charting a mania — like a tulip mania or a dot.com bubble or a housing bubble. or the south sea company crash. first a gradual rise, then a sharp, parabolic takeoff — the mania — followed by a crash. well, the crash is not on the above chart, but see here [from the economist]:

Four_stages_chart

this schematic chart graphs what happens in an economic mania, but what if this also happens with ideas, like — i think — the chart from the 2011 paper suggests? witch hunting came and went, for instance, and there was a definite mania phase there. let’s suppose political correctness is a mania. how far along on the chart are we?

it certainly feels like we’re in the mania phase. please tell me we’re not still in the take off phase! if we are, i’m turning off my internet and crawling under the bed…. it seems like every other day there is a new and even weirder pc episode out there — the appearance of “microaggressions” (if you don’t already know, don’t ask!), just a few days ago facebook adds 50+ genders to its website, yesterday a call to put an end to that very annoying thing called academic freedom. and, of course, the constant political correctness on the tv machine and in the media. i mean, how weirder can it get?! haven’t we reached the top of this mania phase YET?!

i dunno.

i checked out a couple of pc keywords on google ngrams — “racism,” “racist,” “feminism,” and “feminist” — just to see how hot they are. unfortunately, google ngrams cuts off in 2008, so we can’t see the trend up until today. (i searched for the four terms in american english. click on charts for LARGER views.):

google ngram - racism etc.

there seems to have been a peak in the use (in books in american english) of all four terms in the mid-1990s, but who knows what’s happened since 2008. did they keep trending downwards? level off? increase again?

so i checked the same keywords on google trends — web searches for the u.s. only between 2004-present:

google trends - racism etc.

they all seem to be holding pretty steady, except for searches for “racist” which appear to have increased somewhat. i would’ve preferred to see all of these trending downwards…like off the scale.

dunno what any of this means. are we still in a pc mania phase with a trajectory pointing right towards the sky? — and is it all going to get even crazier? or have we already gone over the peak and are witnessing “denial” and maybe heading for a short “return to ‘normal’” peak? no idea.

i just hope it’s over soon. in my lifetime at least! although the problem is who knows what stupid idea the masses will latch onto next? maybe i should be careful what i wish for. the next mania could be even worse (although i have a hard time imagining that!).

oh, btw — i have this idea that human population manias (both economic and ideological ones — also fashion trends) are just examples of herding behavior, and that if someone mapped or charted or graphed these human herding behaviors, they’d look very much like the maps/charts/graphs of, say, the swimming patterns of shoals of fish or the migratory movements of wildebeest or the flights of flocks of seagulls. i’d love to see that done someday!

academic freedom’s overrated, right? “justice” is more important! (don’t ask me who’s going to define justice…presumably not you or me.)

here’s the latest from haaaahvaaaahrd:

“The Doctrine of Academic Freedom”
“Let’s give up on academic freedom in favor of justice

“…In its oft-cited Statement of Principles on Academic Freedom and Tenure, the American Association of University Professors declares that ‘Teachers are entitled to full freedom in research and in the publication of the results.’ In principle, this policy seems sound: It would not do for academics to have their research restricted by the political whims of the moment.

“Yet the liberal obsession with ‘academic freedom’ seems a bit misplaced to me. After all, no one ever has ‘full freedom’ in research and publication. Which research proposals receive funding and what papers are accepted for publication are always contingent on political priorities. The words used to articulate a research question can have implications for its outcome. No academic question is ever ‘free’ from political realities. If our university community opposes racism, sexism, and heterosexism, why should we put up with research that counters our goals simply in the name of ‘academic freedom’?

Instead, I would like to propose a more rigorous standard: one of ‘academic justice.’ When an academic community observes research promoting or justifying oppression, it should ensure that this research does not continue….

yup. she really said that. *facepalm*

Y-chromosome “Adam” was not necessarily human“From the point of view of population genetics, there is absolutely no reason that the common ancestor of all human Y chromosomes must have existed in an individual that we would identify as ‘human’.”

Genomic variation in sharing between siblings“Visscher et al make really nice use of this slight variability in how much of the genome sibs share to learn about how much variation in height within a population is due to genetic variation. They use the fact that sibs who share slightly more of their genome (>0.5) should have more similar heights, than sibs who share less of their genomes (<0.5). This allows them to partition out how much of the resemblance between siblings is due to a shared environment, as opposed to shared genomes…. It also makes me wonder if sibs are actually unconsciously, weakly aware of these subtle genomic differences (through their similarity in a range of traits, including height etc). I could imagine doing a study where siblings (or others) are asked to assess how similar they are/feel, and then assessing whether this is weakly correlated with the fraction of the genome shared. I keep meaning to followup on this idea with some popgen theory to assess how this might play out in modifying kin-selection and altruism between sibs and other relatives." – from graham coop [this guy].

Why the masculine face? Genetic evidence reveals drawbacks of hyper-masculine features“[A]round half the variation in both male and female facial masculinity could be attributed to additive genetic variation…. The extensive genetic variation in masculinity makes more plausible the idea that choosing to mate with a masculine man can result in more attractive offspring. But the genes that made a male face more masculine did not make it more attractive. Worse, these same genes made female faces more masculine and thus less attractive. Families that make manly-looking sons tend also to make masculine-looking daughters.”

Casting Out The Devil“[C]onservatives generally think that liberals are misguided, and live in deep denial of obvious truths about human nature and the way the world actually works (as opposed to the way they think it *ought* to work), liberals view conservatives not just as misguided, but as *morally evil*.” – from malcolm pollack.

Further, the selection of expressed alleles varies randomly from cell to cell, and switches frequently between the two options throughout their lives…. ‘We find that for those genes that are not imprinted, roughly one in five alleles is randomly and dynamically expressed only one at a time,’ says Sandberg. ‘And if one allele is being expressed, the other doesn’t know about it.

Snakes outpacing other vertebrates in race to evolve“The first two full snake genomes to be sequenced – belonging to the Burmese python and the king cobra – show that they have one of the fastest rates of genetic evolution among vertebrates.”

Earliest Stone-Tipped Projectiles from the Ethiopian Rift Date to >279,000 Years Ago“Projectile weapons (i.e. those delivered from a distance) enhanced prehistoric hunting efficiency by enabling higher impact delivery and hunting of a broader range of animals while reducing confrontations with dangerous prey species. Projectiles therefore provided a significant advantage over thrusting spears…. Direct evidence for such projectiles is thus far unknown from >80,000 years ago. Data from velocity-dependent microfracture features, diagnostic damage patterns, and artifact shape reported here indicate that pointed stone artifacts from Ethiopia were used as projectile weapons (in the form of hafted javelin tips) as early as >279,000 years ago.” – see also Oldest Javelins Predate Modern Humans, Raise Questions on Evolution – h/t naturalismo! – and see also Stone tipped spears used 500,000 years ago – thrusting ones, tho.

Iberian Neolithic farmer DNA“‘The Neolithic Portalón individual is genetically most similar to southern Europeans, similar to a Scandinavian Neolithic farmer and the Tyrolean Iceman. In contrast, the Neolithic Portalón individual displays little affinity to two Mesolithic samples from the near-by area, La Brana, demonstrating a distinct change in population history between 7,000 and 4,000 years ago for the northern Iberian Peninsula.’” – @dienekes’.

How genetics are rewriting the history of the Caribbean“The Spanish who arrived in the New World were de facto polygamists who killed or enslaved the local men and impregnated the women.” – from razib.

Male and female brains wired differently, scans reveal“Maps of neural circuitry show women’s brains are suited to social skills and memory, men’s perception and co-ordination…. Maps of neural circuitry showed that on average women’s brains were highly connected across the left and right hemispheres, in contrast to men’s brains, where the connections were typically stronger between the front and back regions.” – see also Sex differences in the structural connectome of the human brain. – and see also Stop the Presses! from malcolm pollack. (^_^)

Promiscuity Is Pragmatic“Why women and other female primates seek out multiple partners…. [T]here are two environmental contexts where women commonly choose multiple partners. The first is where women have more material support from their kin or economic independence from men more generally. This may explain why multiple mating is most common among small-scale matrilocal societies (in which women remain in their home village after marriage), such as the partible paternity societies of South America or the Mosuo of China. It may also explain why female infidelity has increased in Western societies as women have gained greater political and economic independence…. The second environmental context Scelza identified is where the sex ratio is female-biased (indicating a scarcity of men) or there is a high level of male unemployment (indicating a scarcity of men who can provide support).” – one for the gameboyz.

Our IQs Are Climbing, But We’re Not Getting Smarter – re. woodley and armstrong paper.

Academic experts criticise Boris Johnson IQ claims“Dr James Thompson, senior lecturer in psychology at University College London, said Boris had been ‘inelegant’ in his choice of words. Thompson, co-author of Cognitive Capitalism, said: ‘What Boris Johnson has done is inelegantly describe things which in fact do seem to be true: intelligence, however you assess it, is predictive. It’s predicative of income, life span and of occupational status. People are different and have different futures and intelligence seems to be an important part of that.’ He said studies showed there seemed to be a correlation between ‘being bright in youth and doing well in life later’. Asked if inequality was inevitable, he said: ‘In one way that is true. There’s two things, one is that some people are brighter than others and can do more complicated work and that more complicated work is generally more valued.’ However, he added that how much people should be paid was a decision for society. Professor Richard Lynn, co-author of IQ and the Wealth of Nations, said that the association between IQ and income was ‘only modest’. ‘That is because some high IQ people go into jobs that don’t have particularly high earnings like university professors, schoolteachers or social workers. Some professions attract very high IQ people but they don’t have very high earnings,’ he said. ‘You could say that the IQ is only one determinant of high earnings, the others are ambition and motivation and the third one is luck.’” – h/t holtz!

Morality and the State“In general, ‘virtuous’ states – those free of corruption, that do not cheat or steal from their citizens, and that are effective in enforcing laws that are perceived as just – are more effective at promoting the common weal than their opposites. Heraclitus’ dictum that ‘character is destiny’ likely applies to states as well as individuals. I personally think that states are far more likely to be ‘virtuous’ in that sense if their powers are carefully circumscribed and limited.”

Investigation reveals black market in China for research paper authoring“The journal Science has uncovered, via investigation, a thriving black market in science paper authoring—people are paying to have their names added to papers that have been written to describe research efforts…. All in all, the investigative team contacted 27 agencies involved in helping researchers get their work published—only five of them refused an offer to pay for adding a name to a research paper.”

Does Nyborg’s study make sense?“One other thing bothers me. So please let me say it. Why must the Danes prove that they deserve to keep their country to themselves? Isn’t that a basic right? They have only one land to call home…unlike the many ‘refugees’ who regularly visit their own homelands. Once the Danes lose majority status in their country, they’ll be like the Copts of Egypt and other minorities in this world. They’ll have to live by their wits, trying to balance off one potential enemy against another.” – hear, hear! – from peter frost.

Migration Hurts the Homeland“The migration that research shows is unambiguously beneficial is the kind in which young people travel to democracies like America for higher education and then go home. Not only do these young people bring back valuable skills directly learned in the classroom; they bring back political and social attitudes that they have assimilated from their classmates. Their skills raise the productivity of the unskilled majority, and their attitudes accelerate democratization…. Many on the left, for their part, don’t like to recognize that we’re taking away fairy godmothers. They prefer to believe that they’re helping poor people flee difficult situations at home. But we might be feeding a vicious circle, in which home gets worse precisely because the fairy godmothers leave. Humanitarians become caught up trying to help individuals, and therefore miss the larger implications: There are poor people, and there are poor societies. An open door for the talented would help Facebook’s bottom line, but not the bottom billion. – h/t michael story!

great piece by ed west in the spectator yesterday about how political correctness is suppressing scientific inquiry nowadays. (yeah, i know we all know that, and have known it for quite some time now, but it’s good to keep repeating it to the pc-brigade!)

go read it on the spectator website!: Untold truths – how the spirit of inquiry is being suppressed in the West. (read this one, too, while you’re at it: Intelligence is just another privilege you inherited from mummy and daddy.)

here’s a little teaser…

“After the Second World War a new faith, the radical Left, conquered all and academics who proposed vaguely controversial ideas, such as Richard Herrnstein or E.O. Wilson, became the victims of vicious student-led campaigns (Hernstein was talking about IQ and class in a meritocratic society, which is what BoJo was arguing). By the early 1980s British biologist Bill Hamilton wrote in his diaries of a wish to return home because the academic atmosphere in the US was becoming stifling.

“And although America became less radical in the Nixon-Reagan era, academia became more so, especially when the students of 1968 returned as professors, and this political correctness, as it became known, fanned out into the wider culture of media and politics of the 1980s and 1990s. And it hasn’t gone away, you know.

“Soon after Harvard alumni Jason Richwine stated that Hispanic school scores in the US had not improved in four generations, he was sacked by his think-tank and publicly disgraced. 1,200 Harvard students signed a petition calling for Richwine to have his doctorate taken away, and many of them wrote that even if his research was academically sound, and accurate, he should still be punished for studying things that might promote ‘discrimination and exclusion’. These are America’s future leaders….

yeah. great. =/
