Mexican skeleton gives clue to American ancestry“Naia’s mitochondrial DNA reveals genetic signatures in common with modern Native Americans, despite her very different skull shape. ‘You can never exclude that Native Americans have more than one group of ancestors,’ says Chatters. But his team’s data, he points out, are consistent with the idea that Native Americans evolved from Siberian ancestors…. The new DNA results indicate that the very different skulls of modern Native Americans have evolved on North American soil.” – see also jennifer raff.

Religiosity is negatively associated with later-life intelligence, but not with age-related cognitive decline – from stuart ritchie et al. – “Religious belief was negatively associated with intelligence in old age. Neither religious belief nor attendance was related to cognitive decline.”

The relationship between Microcephalin, ASPM and intelligence: A reconsideration“At the population-level IQ and Microcephalin correlate significantly (.790 and .847). Microcephalin significantly predicts population differences in IQ. Microcephalin significantly predicts infectious disease burden. Vice versa in the case of Microcephalin. Microcephalin increased disease-resistance allowing access to new cognitive niches.” – from woodley et al. – h/t lars penke!

Molecular genetic contributions to socioeconomic status and intelligence“21% of the variation in education, 18% of the variation in socioeconomic status, and 29% of the variation in general cognitive ability was explained by variation in common SNPs (SEs ~ 5%). The SNP-based genetic correlations of education and socioeconomic status with general intelligence were 0.95 (SE 0.13) and 0.26 (0.16), respectively. There are genetic contributions to intelligence and education with near-complete overlap between common additive SNP effects on these traits (genetic correlation ~ 1). Genetic influences on socioeconomic status are also associated with the genetic foundations of intelligence. The results are also compatible with substantial environmental contributions to socioeconomic status.”

Longevity Gene May Enhance Cognition“Mice with the KLOTHO gene variant lived longer and were smarter.”

Short men are likely to live longer because they carry the ‘longevity gene’, scientists reveal – short japanese men… “The so-called ‘longevity gene’ FOXO3 has been proven to enhance lifespan in animal tests but has never before been linked to variations in height in humans. A new scientific study, the largest of its kind and involving more than 8,000 aging American-Japanese men in Hawaii, conclusively showed a direct connection between short height and long life. FOXO3, they found, leads to smaller body size during early development and a longer lifespan overall. Short men were also more likely to have lower blood insulin levels and less likely to get cancer.” – h/t eddy elmer!

The coerced consensus“What is going on in academia when demonising and silencing your opponents has become so acceptable? It’s not just climate change. The nature-nurture debate is also policed by zealots, although less so than in the 1970s when any mention of genes and behaviour led to accusations of fascism…. Truly, the old joke is becoming ever more true: what’s the opposite of diversity? University.” – from matt ridley.

Stanford scholar shows Koreans and Americans tackle moral dilemmas using different brain regions – very small sample size, but… “Korean participants showed greater activity in brain regions associated with intuition, approximation and emotions: the putamen, the dorsolateral prefrontal cortex and the postcentral sulcus. Han posits that Korean participants consciously controlled their initial emotional reactions (such as disgust) to reach a decision that protected the largest number of people. In contrast, Americans took longer to ponder dilemmas that involved physically harming particular people. They also relied on brain regions associated with conflict management and, to a lesser degree, novelty: the anterior cingulate cortex and the frontopolar cortex. Han hypothesizes that Americans are exposed to socio-personal conflict more often than Koreans, whose society values social harmony over the expression of individual desires.”

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.”

Evolution equally efficient in removing deleterious variants in Europeans and West Africans“…but apparently not in Denisovans who accumulated deleterious mutations at a higher rate than modern humans.” – @dienekes’.

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.

Fruit-loving lemurs score higher on spatial memory tests“Food-finding tests in five lemur species show that fruit-eaters may have better spatial memory than lemurs with a more varied diet. The results support the idea that relying on foods that are seasonally available and far-flung gives a competitive edge to individuals with certain cognitive abilities — such as remembering where the goodies are.”

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!

[H]ow individuals conduct themselves when they have money has everything to do with who they are as a person. Money doesn’t make a person more or less selfish. If you are a genuinely kind and giving person, you’ll continue to be that way no matter how many zeros are on your paycheck.'”

Genetic origins of high-altitude adaptations in Tibetans“Genetic adaptations for life at high elevations found in residents of the Tibetan plateau likely originated around 30,000 years ago in peoples related to contemporary Sherpa. These genes were passed on to more recent migrants from lower elevations via population mixing, and then amplified by natural selection in the modern Tibetan gene pool, according to a new study.” – see also: Admixture facilitates genetic adaptations to high altitude in Tibet – see also: A novel mechanism for getting high – from greg cochran. – see also: Tibetan mastiffs equally adapted to high altitudes of Tibet.

Immediate replacement of fishing with dairying by the earliest farmers of the northeast Atlantic archipelagos [i.e. british isles] – “These new findings…unequivocally confirm rejection of marine resources by early farmers coinciding with the adoption of intensive dairy farming. This pattern of Neolithization contrasts markedly to that occurring contemporaneously in the Baltic, suggesting that geographically distinct ecological and cultural influences dictated the evolution of subsistence practices at this critical phase of European prehistory.”

The booms and busts of Neolithic Europe (and their potential impact on our DNA)“most of the interactions between the genetically Near Eastern-like Neolithic farmers and indigenous European hunter-gatherers, including mixing, in all likelihood took place on the peripheries of the farming societies. If so, then perhaps every time there was a bust, it was the relatively more admixed, or even more hunter-gatherer-like, farmer groups from the peripheries that took advantage of the situation and moved in to grab some land in the depopulated regions? In other words, this might have been the process which led to the well-documented reemergence of hunter-gatherer-derived ancestry in the heart of Europe after the early Neolithic.” – @eurogenes.

Study demonstrates evolutionary ‘fitness’ not the most important determinant of success“By modelling populations over long timescales, the study showed that the ‘fitness’ of their traits was not the most important determinant of success. Instead, the most genetically available mutations dominated the changes in traits. The researchers found that the ‘fittest’ simply did not have time to be found, or to fix in the population over evolutionary timescales. The findings suggest that life on Earth today may not have come about by ‘survival of the fittest’, but rather by the ‘arrival of the frequent’.”

Burakumin, Paekchong, and Cagots“Human evolution is a logarithmic curve where most of the interesting changes have happened since the advent of farming and complex societies. *Homo sapiens* was not a culmination but rather a beginning…of gene-culture co-evolution.

He says: ‘In all societies, what seems to matter is just who your parents are. At the extreme, we see in modern Sweden an extensive system of public education and social support. Yet underlying mobility rates are no higher in modern Sweden than in pre-industrial Sweden or medieval England.’ He also notes that even in revolutionary societies, such as in Communist China, people with aristocratic surnames also turn up at the top, showing that once again Darwin trumps Marx.” – from ed west. – see also: Everyone likes the idea of equal opportunity.

Males and females differ in specific brain structures“Reviewing over 20 years of neuroscience research into sex differences in brain structure, researchers have conducted the first meta-analysis of the evidence. The team performed a quantitative review of the brain imaging literature testing overall sex differences in total and regional brain volumes. They found that males on average have larger total brain volumes than women (by 8 to 13 percent). Looking more closely, the researchers found differences in volume between the sexes were located in several regions. These included parts of the limbic system, and the language system.”

Major sex differences in brain gene expression – from mr. mangan, esq. – also: How Can This Be? – from malcolm pollack.

How much do sex differences matter in sports?“Thanks in large part to testosterone, men are generally heavier and taller than women. They have longer limbs relative to their height, bigger hearts and lungs, less fat, denser bones, more oxygen-carrying red blood cells, heavier skeletons that support more muscle — 80 percent more in the upper body, on average, which is about the difference between male and female gorillas — and narrower hips that make for more efficient running and decrease the chance of injury. But since these differences generally don’t appear until puberty, boys’ and girls’ records in track tend to be identical before age 10.

“WASHINGTON (AP) – You can take our word for it. Americans don’t trust each other anymore.

These days, only one-third of Americans say most people can be trusted. Half felt that way in 1972, when the General Social Survey first asked the question.

“Forty years later, a record high of nearly two-thirds say ‘you can’t be too careful’ in dealing with people.

“An AP-GfK poll conducted last month found that Americans are suspicious of each other in everyday encounters. Less than one-third expressed a lot of trust in clerks who swipe their credit cards, drivers on the road, or people they meet when traveling.

“‘I’m leery of everybody,’ said Bart Murawski, 27, of Albany, N.Y. ‘Caution is always a factor.’

“Does it matter that Americans are suspicious of one another? Yes, say worried political and social scientists.

“What’s known as ‘social trust’ brings good things.

“A society where it’s easier to compromise or make a deal. Where people are willing to work with those who are different from them for the common good. Where trust appears to promote economic growth.

Distrust, on the other hand, seems to encourage corruption. At the least, it diverts energy to counting change, drawing up 100-page legal contracts and building gated communities.

“Even the rancor and gridlock in politics might stem from the effects of an increasingly distrustful citizenry, said April K. Clark, a Purdue University political scientist and public opinion researcher.

“‘It’s like the rules of the game,’ Clark said. ‘When trust is low, the way we react and behave with each other becomes less civil’

“There’s no easy fix….”

hmmmm. now what could be different about america today versus america forty years ago? hmmmm. i just can’t imagine [see bottom chart in that section].

as robert putnam discovered a few years ago [pdf]: “New evidence from the US suggests that in ethnically diverse neighbourhoods residents of all races tend to ‘hunker down’. Trust (even of one’s own race) is lower, altruism and community cooperation rarer, friends fewer.”

in other words, Diversity Doesn’t Work. it doesn’t even work in twenty-plus million (20+ MILLION!) virtual diverse worlds! no matter how you cut it, Diversity Doesn’t Work.

but the social scientists keep telling us that it will work out great in the end, just you wait and see! just like in syria, indonesia, kenya, the balkans, egypt, rwanda, burma, the caucasuses, malaysia, northern ireland, afghanistan, the philippines, cyprus….

‘Rare’ Gene Common in African Descendants, May Contribute to Heart Disease“Researchers at Weill Cornell Medical College have found that a genetic variation that is linked to increased levels of triglycerides — fats in the blood associated with disorders such as heart disease, type 2 diabetes, obesity and stroke — is far more common than previously believed and disproportionally affects people of African ancestry…. The finding offers a clue as to why Africans and people of African descent have an increased risk of cardiovascular disease and type 2 diabetes compared to many other populations, says the study’s senior author, Dr. Ronald Crystal, chairman of genetic medicine at Weill Cornell. African Americans with the variant had, on average, 52 percent higher triglyceride levels compared with blacks in the study who did not have the variant…. The gene variant the scientists studied is a single point mutation — a replacement of one of DNA segment with another — in the ApoE gene, which carries fats and other molecules through the blood.” – h/t hbd bibliography!

A gene mutation for excessive alcohol drinking found“UK researchers have discovered a gene that regulates alcohol consumption and when faulty can cause excessive drinking…. [M]ice with a genetic mutation to the gene Gabrb1 overwhelmingly preferred drinking alcohol over water, choosing to consume almost 85% of their daily fluid as drinks containing alcohol…. Dr Quentin Anstee, Consultant Hepatologist at Newcastle University, joint lead author said: ‘It’s amazing to think that a small change in the code for just one gene can have such profound effects on complex behaviours like alcohol consumption.’ – see also Firewater from greg cochran.

Predicting Human Body Height from DNA“Predicting tall stature from these 180 DNA variants resulted in an accuracy of 0.75 on a scale from 0.5 (meaning random prediction) to 1.0 (completely accurate prediction). ‘Although the achieved DNA-based prediction accuracy for tall stature is still somewhat lower than we previously established for eye color, hair color and age,’ said Kayser, ‘I expect that upcoming new knowledge on height genetics will further increase the accuracy in predicting tall stature, and eventually the full range of body height, from DNA.'”

Study Connects Dots Between Genes, Human Behavior“The team studied individuals with a rare disorder known as Williams syndrome. By measuring neural activity in the brain associated with the distinct language skills and facial recognition abilities that are typical of the syndrome, they showed that Williams is due not to a single gene but to distinct subsets of genes, hinting that the syndrome is more complex than originally thought.”

Different Gene Expression in Male, Female Brains May Help Explain Brain Disorder Differences“UCL scientists have shown that there are widespread differences in how genes, the basic building blocks of the human body, are expressed in men and women’s brains. Based on post-mortem adult human brain and spinal cord samples from over 100 individuals, scientists at the UCL Institute of Neurology were able to study the expression of every gene in 12 brain regions…. They found that the way that the genes are expressed in the brains of men and women were different in all major brain regions and these differences involved 2.5% of all the genes expressed in the brain.” – h/t heartiste!

(note: comments do not require an email. giant sloth!)

you’ve probably already seen/read about the latest case of politically correct researchers discovering that Diversity Doesn’t Work. if not, see here: The Paradox of Diverse Communities. or steve sailer: Dr. Vibrant notices diversity v. community trade-off.

i’ve just read the original research paper — The (In)compatibility of Diversity and Sense of Community [pdf] — and it is MUCH funnier than any of us might’ve predicted! it would’ve been absolutely hilarious, except for the fact that these people take themselves seriously and keep trying to foist diversity onto the world.

first of all, in case you didn’t know (i didn’t), these people studying the dynamics of communities — the ones who like to promote diversity — are known as “community psychologists.” no, really. who on EARTH hires a community psychologist? besides universities, that is. real, actual communities? doubt it. some governmental agencies? probably (i dread to imagine). waste of taxpayers’ money. (judging by their own research results!)

secondly, their goal really IS to promote diversity — even though, as their research keeps showing, Diversity Doesn’t Work. apparently, it’s part of the mission statement of the american psychological association‘s society for community research and action (scra). unfortunately, the scra’s mission statement doesn’t seem to be accessible to non-members [link to the pdf]. but here from the “(In)compatiblity” paper:

“Fostering respect for diversity is important for community psychologists and is embedded in the mission statement of the Society for Community Research and Action (SCRA), Division 27 of the American Psychological Association. Specifically, one of the goals of SCRA is ‘to promote … greater inclusion for historically marginalized groups, and respecting all cultures’ (SCRA 2010, p. 13). To this end, community psychologists aim to encourage contexts that facilitate respect for diversity, and view these contexts as promoting individual and collective wellbeing (Prilleltensky 2001).”

never mind that they, themselves, keep finding that Diversity Doesn’t Work.


from this latest piece of research:

[W]e simulated social network formation in 500 neighborhoods that varied in their level of integration, each time computing the resulting network’s clustering coefficient (steps 2–5, the integration loop). Figure 4 plots each neighborhood’s opportunity for residents to develop a respect for diversity (as measured by its level of residential integration) and its capacity to foster a sense of community (as measured by its residents’ personal network density). A very clear, albeit somewhat non-linear, negative correlation between diversity and sense of community emerges (r = -0.85, p.001; step 6). Neighborhoods with the greatest opportunity for residents to develop a respect for diversity (i.e. highly integrated neighborhoods) have the least capacity to foster a sense of community. Likewise, neighborhoods with the least opportunity for residents to develop a respect for diversity (i.e. highly segregated neighborhoods) have the greatest capacity to foster a sense of community. This finding suggests that, the values of community psychology notwithstanding, it is not possible to simultaneously promote respect for diversity and sense of community in a typical world where relationship formation is driven by homophily and proximity.”

“…the values of community psychology notwithstanding….” heh!

here is figure 4:

(in)compatability paper - figure 04

since these results made the researchers very, very sad, they decided that simulating “social network formations” just 500 times (what they did in the first round) wasn’t enough, so they went for twenty million+ (yes, 20 MILLION PLUS!) simulations, figuring, i guess, that they’d find that diversity does work somewhere! from the paper:

“Perhaps it is possible to simultaneously promote diversity and sense of community in a slightly different worlds where behavioral tendencies toward homophily and/or proximity are weaker, or stronger, or even reversed. To consider this possibility, we repeated the analysis shown in Fig. 4 using different levels of homophily and proximity. Specifically, we examined diversity and sense of community in 500 simulated neighborhoods varying in their level of integration (steps 2–6), for every level of homophily between -5 and 5 (in increments of 0.05; step 7) and every level of proximity between -5 and 5 (in increments of 0.05; step 8). This required slightly more that 20 million separate simulations (i.e. 500 neighborhoods 9 201 levels of homophily 9 201 levels of proximity) and approximately 6,000 processor-hours to complete….

“The findings illustrated in Fig. 5 confirm that the negative relationship between diversity and sense of community observed in Fig. 4 is not simply an artifact of the particular combination of behavioral tendencies toward homophily and proximity (i.e. bH = 2.5 and bP = 2.5) we initially examined. All points in the upper-right quadrant of Fig. 5 are dark, indicating that all combinations of homophily and proximity yield a negative relationship between diversity and sense of community. That is, in any world where individuals exhibit at least some tendency to form relationships with similar others (i.e. bH[0) and at least some tendency to form relationships with nearby others (i.e. bP[0), diversity and sense of community are negatively related. It is important to note that all studies of human social networks have observed behavioral tendencies toward both homophily and proximity, while none have found worlds where one or both of these behavioral tendencies was missing. Thus, while the findings illustrated in Fig. 4 suggest that diversity and sense of community are negatively related *in a typical world*, those illustrated in Fig. 5 suggest this negative relationship would persist *in all reasonably likely worlds*.

in other words, Diversity Doesn’t Work. not even in imaginary worlds, let alone the real world. here is figure 5:

(in)compatability paper - figure 05

“the community-diversity dialectic.” that’s sad community psychologist-speak for “reality.”

more and more, politically correct social researchers — like putnam [pdf] and now these guys — are discovering that Diversity Doesn’t Work, and they’re finding it hard to express their disappointment. their hurt feelings. the phrase “community-diversity dialectic” was coined in this paper: Reconcilable Differences? Human Diversity, Cultural Relativity, and Sense of Community.

they’re all still trying to spin diversity as something workable, of course — all of these researchers who keep finding that Diversity Doesn’t Work. primarily because diversity is important to them — they don’t seem to give a sh*t about what the members of various communities think or how they feel. again, from the “(In)compatiblity” paper:

“Over 30 years ago, Rappaport (1981) noted that ‘the most important and interesting aspects of community life are by their very nature paradoxical’ (p. 20). Such is the case for two of community psychology’s core values: promoting contexts that are likely to increase respect diversity and promoting contexts that are likely to increase a sense of community (Townley et al. 2011). Results of our model suggest that this community-diversity dialectic can result from common behavioral tendencies toward homophily and proximity. Moreover, given the universality of these behavioral tendencies, it is unlikely that community psychologists can shift them sufficiently to simultaneously promote respect for diversity and sense of community. However, through divergent reasoning, community psychologists can seek a contextually-appropriate balance between these two opposing goals that are near and dear to our field.

right. ok. so…the goal of community psychology seems to be to make community psychologists feel better — i.e. to achieve goals that are “near and dear” to THEM — and NOT to … you know … actually HELP COMMUNITIES.

The second pulse—reflected by longer, younger tracts—is more similar to present-day West-Central African populations, supporting historical records of later transatlantic deportation. Surprisingly, we also identify a Latino-specific European component that has significantly diverged from its parental Iberian source populations, presumably as a result of small European founder population size.
