pretty much the only political issue that i get worked up about is immigration — mass immigration to be specific. too much immigration (esp. all at once) just doesn’t seem like a good idea to me, for several reasons: 1) assimilation is *not* a thing (’cause of human biodiversity) — what you get with a large influx of a different people (or peoples) into a society is change, or at least division (see Albion’s Seed and American Nations), not assimilation — and while change is not necessarily a bad thing, i think we should be cautious, since no one can know what the outcome will be; 2) diversity doesn’t seem to work very well, not if you want a free and open and liberally democratic nation; and 3) the negative economic effects, in particular the supply of too much cheap labor.

that last reason really applies to african americans, which is why i can never figure out why they’re not more p*ssed off at the current immigration situation.

in 2013, three members of the u.s. commission on civil rightsabigail thernstrom, gail heriot, and peter kirsanow — wrote a letter to the congressional black caucus (cbc) outlining the disastrous consequences the recent mass immigration has had on lower-skilled african-americans and how an amnesty would just further exacerbate those. i can’t see anything to argue with in their letter (looking away from their obvious cluelessness re. human biology and hbd), so i’m just going to reproduce it here (stole it from here — my bolding). too bad the cbc are just another bunch of corrupt politicians who don’t give a sh*t about their constituents:

Dear Chairman Fudge:

We write in our individual capacities as three members of the eight-member U.S. Commission on Civil Rights, and not on behalf of the Commission as a whole. In light of recent debates on comprehensive immigration reform, we are writing to address a rarely-discussed effect of granting legal status or effective amnesty to illegal immigrants. Such grant of legal status will likely disproportionately harm lower-skilled African-Americans by making it more difficult for them to obtain employment and depressing their wages when they do obtain employment. The increased employment difficulties will likely have negative consequences that extend far beyond economics.

In 2008, the Commission held a briefing regarding the impact of illegal immigration on the wages and employment opportunities of African-Americans.1 The testimony at the briefing indicated that illegal immigration disproportionately impacts the wages and employment opportunities of African-American men.2

The briefing witnesses, well-regarded scholars from leading universities and independent groups, were ideologically diverse. All the witnesses acknowledged that illegal immigration has a negative impact on black employment, both in terms of employment opportunities and wages. The witnesses differed on the extent of that impact, but every witness agreed that illegal immigration has a discernible negative effect on black employment. For example, Professor Gordon Hanson’s research showed that “Immigration . . . accounts for about 40 percent of the 18 percentage point decline [from 1960-2000] in black employment rates.”3 Professor Vernon Briggs wrote that illegal immigrants and blacks (who are disproportionately likely to be low-skilled) often find themselves in competition for the same jobs, and the huge number of illegal immigrants ensures that there is a continual surplus of low-skilled labor, thus preventing wages from rising.4 Professor Gerald Jaynes’s research found that illegal immigrants had displaced U.S. citizens in industries that had traditionally employed large numbers of African-Americans, such as meatpacking.5

Illegal immigration has a disparate impact on African-American men because these men are disproportionately represented in the low-skilled labor force. The Census Bureau released a new report on educational attainment after the Commission issued its report. This report, released in February 2012, found that 50.9 percent of native-born blacks had not continued their education beyond high school.6 The same report found that 75.5 percent of foreign-born Hispanics had not been educated beyond high school, although it does not disaggregate foreign-born Hispanics who are legal immigrants from those who are illegal immigrants.7 However, Professor Briggs estimated that illegal immigrants or former illegal immigrants who received amnesty constitute a third to over a half of the total foreign-born population.8 Foreign-born Hispanics who are in the United States illegally are disproportionately male.9 African-Americans who have not pursued education beyond high school are also disproportionately male.10 These poor educational attainment levels usually relegate both African-American men and illegal immigrant men to the same low-skilled labor market, where they must compete against each other for work.11

The obvious question is whether there are sufficient jobs in the low-skilled labor market for both African-Americans and illegal immigrants. The answer is no. As Professor Briggs noted in his testimony to the Commission, “In February 2008 . . . the national unemployment rate was 4.8 percent, but the unemployment rate for adults (over 25 years old) without a high school diploma was 7.3 percent.”12 During 2007, “Black American adult workers without a high school diploma had an unemployment rate of 12.0 percent, and those with only a high school diploma had an unemployment rate of 7.3 percent.”13 These statistics suggest both that there is an overall surplus of workers in the low-skilled labor market, and that African-Americans are particularly disfavored by employers.14 More recently, Professor George Borjas of Harvard wrote:

‘Classifying workers by education level and age and comparing differences across groups over time shows that a 10 percent increase in the size of an education/age group due to the entry of immigrants (both legal and illegal) reduces the wage of native-born men in that group by 3.7 percent and the wage of all native-born workers by 2.5 percent. . . . The same type of education/age comparison used to measure the wage impact shows that a 10 percent increase in the size of a skill group reduced the fraction of native-born blacks in that group holding a job by 5.1 percentage points.15

Furthermore, these statistics reflect an economy that was not experiencing the persistent stagnation we are experiencing today. The country’s economic woes have disproportionately harmed African-Americans, especially those with little education. In 2011, 24.6 percent of African-Americans without a high school diploma were unemployed, as were 15.5 percent of African-Americans with only a high school diploma.16 Two and half years into the economic recovery, African-Americans face particular difficulty obtaining employment. According to the Bureau of Labor Statistics, the seasonally adjusted January 2013 unemployment rate for all black Americans — not just those with few skills — was 13.8 percent, nearly twice the white unemployment rate of 7.0 percent.17 The economy has a glut of low-skilled workers, not a shortage.

Not only do illegal immigrants compete for jobs with African-Americans, but that competition drives down wages for the jobs that are available. Harvard professor George Borjas writes:

‘Illegal immigration reduces the wages of native workers by an estimated $99 to $118 billion a year . . . . A theory-based framework predicts that the immigrants who entered the country from 1990 to 2010 reduced the average annual earnings of American workers by $1,396 in the short run. Because immigration (legal and illegal) increased the supply of workers unevenly, the impact varies across skill groups, with high school dropouts being the most negatively affected group.18

Immigration, both legal and illegal, resulted in a disproportionately large increase in the number of high school dropouts in the labor pool. This caused a drop in wages among the poorest and least-educated members of the workforce.19 As discussed above, these people are disproportionately likely to be African-American men. Furthermore, there is evidence that wages for these men have not just failed to increase as much as they would have in the absence of illegal immigration. Their real wages, the number of dollars they take home at the end of the week, have actually diminished. Julie Hotchkiss, a research economist and policy advisor at the Federal Reserve Bank of Atlanta, estimated that “as a result of this growth in the share of undocumented workers, the annual earnings of the average documented worker in Georgia in 2007 were 2.9 percent ($960) lower than they were in 2000. . . . [A]nnual earnings for the average documented worker in the leisure and hospitality sector in 2007 were 9.1 percent ($1,520) lower than they were in 2000.”20 A $960 annual decrease may not seem like much to a lawyer or a doctor. But as President Obama noted in regard to the 2012 payroll tax cut extension, an extra $80 a month makes a big difference to many families: “It means $40 extra in their paycheck, and that $40 helps to pay the rent, the groceries, the rising cost of gas . . . .”21

The consequences of illegal immigration for black men and the black community in general are not limited to wages. In another study, Borjas found that lower wages and fewer jobs also correlate with an increase in the black incarceration rate.

‘Our study suggests that a 10% immigrant-induced increase in the supply of a particular skill group is associated with a reduction in the black wage of 2.5%, a reduction in the black employment rate of 5.9 percentage points, and an increase in the black institutionalization rate of 1.3%. Among white men, the same 10% increase in supply reduces the wage by 3.2%, but has much weaker employment and incarceration effects: a 2.1 percentage-point reduction in the employment rate and a 0.2 percentage-point increase in the incarceration rate. It seems, therefore, that black employment and incarceration rates are more sensitive to immigration rates than those of whites.22

Both lower wages and incarceration likely contribute to one of the most serious problems facing the African-American community today: the dearth of intact nuclear families. The disintegration of the black family began to accelerate during the 1960s. It is one of the great tragedies of modern America that the disintegration of the African-American family has shown no signs of abating.23 Seventy-two percent of African-American children are born out of wedlock.24 It is now commonly recognized that children born out of wedlock are far more likely to experience a host of negative outcomes than are children raised by their own biological, married parents.25

Married men are more likely to be employed and to have higher earnings than unmarried men, although the relationship between marriage and economic success is complex. However, it is obvious that men who are unemployed or are incarcerated are far less appealing prospective spouses than men who hold down a steady job.26 Yet there are fewer and fewer jobs available — and at lower wages — for men in traditionally masculine industries.27 Giving amnesty to illegal immigrants would only exacerbate this problem facing low-skilled men, who are disproportionately African-American. The dearth of job opportunities gives these men less confidence in their ability to support a family, and gives women reason to fear that these prospective husbands will be only another mouth to feed.

Granting amnesty to illegal immigrants will only further harm African-American workers. Not only will the low-skilled labor market continue to experience a surplus of workers, making it difficult for African-Americans to find job opportunities, but African-Americans will be deprived of one of their few advantages in this market. Some states require private employers to use E-Verify to establish that their workers are in the country legally. This levels the playing field a bit for African-Americans. If illegal immigrants are granted legal status, this small advantage disappears.

Furthermore, recent history shows that granting amnesty to illegal immigrants will encourage more people to come to the United States illegally. The 1986 amnesty did not solve the illegal immigration problem. To the contrary, that amnesty established the precedent that if you come to America illegally, eventually you will obtain legal status. Thus, it is likely that if illegal immigrants are granted legal status, more people will come to America illegally and will further crowd African-American men (and other low-skilled men and women) out of the workforce.

Before the federal government decides to grant legal status to illegal immigrants, due deliberation should be given to what effect such grant will have on the employment and earnings prospects of low-skill Americans generally and black Americans specifically. We respectfully submit that granting such legal status is not without substantial costs to American workers.

2 Id. at 3, Finding 5:

Illegal immigration to the United States in recent decades has tended to depress both wages and employment rates for low-skilled American citizens, a disproportionate number of whom are black men. Expert economic opinions concerning the negative effects range from modest to significant. Those panelists that found modest effects overall nonetheless found significant effects in industry sectors such as meatpacking and construction.

11 THE IMPACT OF ILLEGAL IMMIGRATION, supra note 1, Statement of Vernon M. Briggs, Jr., at 37.

[I]t is not everywhere that there is likely to be significant competition between low skilled black workers and illegal immigrant workers, but there are ample circumstances where there is – such as the large metropolitan labor markets of Los Angeles, New York, San Francisco, Chicago, Miami and Washington-Baltimore. Moreover, some of the fastest growing immigrant concentrations are now taking place in the urban and rural labor markets of the states of the Southeast – such as Georgia, North Carolina and Virginia, which never before were significant immigrant receiving states in previous eras of mass immigration. Indeed, about 26 percent of the nation’s foreign-born population are now found in the states of the South – the highest percentage ever for this region. There is mounting evidence that many of these new immigrants in this region are illegal immigrants.

Other evidence, including that by ethnographers, indicates that employers filling low-wage jobs requiring little reading/writing or communication clearly prefer immigrants to native-born blacks, and encourage informal networks through which immigrants gain better access to these jobs. The native-born black workers likely would be interested in some, but not all of these jobs, depending on their wages.

19 Id.:

[The simulation] shows that immigration particularly increased supply at the bottom and top of the education distribution. Immigration increased the effective number of hours supplied by high school dropouts to 25.9 percent, and those of workers with more than a college degree by 15.0 percent. In contrast, immigration increased the number of hours supplied by workers with 12 to 15 years of school by only 6 to 8 percent. Overall, immigration increased effective supply by 10.6 percent during the two-decade period. Because of the skewed nature of the supply shift, the simulation shows that immigration particularly affected the wage of native workers at the two ends of the education distribution. The large supply increase experienced by high school dropouts decreased the wage of this group by 6.2 percent in the short run and 3.1 percent in the long run. Similarly, the wage declines for the most highly skilled workers (those with more than a college degree) were 4.1 percent in the short run and 0.9 percent in the long term.

[A] 1996 federal study found that the overall rate of child maltreatment among single- parent households was nearly double that of two-parent families: 27.3 children per 1,000 were maltreated in single-parent families, whereas 15.5 children per 1,000 were maltreated in two-parent families. Another study found that 7 percent of children who had lived with a single parent had been sexually abused, compared to 4 percent of children who lived in an intact, biological family. Still another study found that children were half as likely to suffer physical abuse involving a traumatic brain injury when they lived in a household with their father, compared to children living in a fatherless family.

Research also indicates that children living in stepfamilies are more likely to suffer from abuse. One study by David Finkelhofer of the University of New Hampshire and his colleagues found that “children currently living in single parent and stepfamilies had significantly greater lifetime exposure than those living with two biological or adoptive parents” to five different forms of victimization—sexual assault, child maltreatment, assault by peers or siblings, being a victim of a crime, or witnessing violence. Other studies have found that children are markedly more likely to be killed or sexually abused by stepfathers, compared to children living in an intact, married household.

Our Cats, Ourselves“Which brings us to the genome of one critical tame animal: ourselves, humans. The Nobel Prize-winning zoologist Konrad Z. Lorenz once suggested that humans were subject to the same dynamics of domestication. Our brain and body sizes peaked during the end of the last ice age, and declined with the spread of agriculture…. Our cultural flexibility and creativity since the end of the ice age have not freed humans from evolutionary forces, but have opened up novel and startling paths. Thinking of domestication as an evolutionary process that occurs through ‘artificial’ selection creates a false dichotomy of nurture and nature that plays into a conceit of human exceptionalism. In fact, the idea that we are apart from nature, that it is ours to tame and exploit, is an outmoded approach. A more useful interpretation is that over the past 10,000 years, humans fashioned their own ecosystem. We were part of a natural process that altered the landscape…. The same forces that reshaped the genomes of our domesticates also reshaped ours.” – from razib. in the new york times! (^_^)

Ancient Easter Islanders Interbred With Native Americans“According to the recent study conducted by geneticists, the ancient inhabitants of Easter Island met and interbred with Native Americans long before Westerners arrived…. The recent genetic study is published on Thursday in the Current Biology journal. According to the study, these ancient people had significant contact with Native Americans hundreds of years ago, before the westerners reached the Island in 1722…. The finding of the study suggests that the intermixing occurred 19 to 23 generations ago. The researchers said that the Polynesian people (Rapa Nui’s) are not believed to have started mixing with Europeans until much later, the 19th century. Malaspinas said the genetic ancestry of today’s Rapa Nui people is roughly 75% Polynesian, 15% European and 10% Native American.”

The second answer is that they, like biological parents, are not miracle-workers. They will be unable to mold the child.

DNA USA*“[A]bout about 4 percent of whites have at least 1 percent or more African ancestry. Although it is a relatively small percentage, the percentage indicates that an individual with at least 1 percent African ancestry had an African ancestor within the last six generations, or in the last 200 years. This data also suggests that individuals with mixed parentage at some point were absorbed into the white population. Looking a little more deeply into the data, Kasia also found that the percentage of whites with hidden African ancestry differed significantly from state-to-state. Southern states with the highest African American populations, tended to have the highest percentages of hidden African ancestry…. Previous published studies estimate that on average African Americans had about 82 percent African ancestry and about 18 percent European ancestry. But in self-identified African Americans in 23andMe’s database, Kasia found the average amount of African ancestry was closer to 73 percent. Kasia found significant differences in state-to-state comparisons. African Americans in the northern and western states have more mixed ancestry than those in the southern states…. On average Latinos had about 70 percent European ancestry, 14 percent Native American ancestry and 6 percent African ancestry. The remaining ancestry is difficult to assign because the DNA is either shared by a number of different populations around the world, or because it’s from understudied populations, such as Native Americans.” – from 23andMe.

Among the most egregious errors they discovered were those in the papers that focused on academic performance. A correlation had been repeatedly found between high self-esteem and good grades. So, the logic went, if you boosted self-esteem you’d also boost grades. But the authors had made one of the most elementary mistakes in science. ‘When they tracked people over time,’ says Baumeister, ‘the grades came first, and then the self-esteem. High self-esteem was a *result* of good grades, not a cause.'” – h/t matthew wygant!

Genetic Influences on Political Ideologies: Twin Analyses of 19 Measures of Political Ideologies from Five Democracies and Genome-Wide Findings from Three Populations“Here we present results from original analyses of a combined sample of over 12,000 twins pairs, ascertained from nine different studies conducted in five democracies, sampled over the course of four decades. We provide evidence that genetic factors play a role in the formation of political ideology, regardless of how ideology is measured, the era, or the population sampled…. We then present results from one of the first genome-wide association studies on political ideology using data from three samples: a 1990 Australian sample involving 6,894 individuals from 3,516 families; a 2008 Australian sample of 1,160 related individuals from 635 families and a 2010 Swedish sample involving 3,334 individuals from 2,607 families. No polymorphisms reached genome-wide significance in the meta-analysis. The combined evidence suggests that political ideology constitutes a fundamental aspect of one’s genetically informed psychological disposition, but as Fisher proposed long ago, genetic influences on complex traits will be composed of thousands of markers of very small effects and it will require extremely large samples to have enough power in order to identify specific polymorphisms related to complex social traits.”

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.

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.

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!

for your consideration, a review by andrew sabisky of tatu vanhanen‘s Ethnic Conflicts: Their Biological Roots in Ethnic Nepotism (links added by me). thanks, andrew! (^_^)

Ethnic Conflicts: Their Biological Roots in Ethnic Nepotism – some thoughts

Nationalism, once thought to be a monster whose thirst for blood had been thoroughly slaked by mass warfare, is making a resurgent comeback throughout Europe. Ostensibly fired by opposition to both Islam and the European Union, Marine le Pen & Geert Wilders – amongst others – have made major polling gains: future electoral victories promise or threaten, depending on your point of view. Golden Dawn have already achieved ballot box success in Greece. Robert Putnam’s work shows that interindividual trust in America has undergone a spectacular decline since the 1960s, accompanying the rise of ethnic diversity. In fact, recent modeling by unwilling sociologists shows that not even in 20 million possible worlds can ethnic diversity increase without a consequent decrease in community harmony. But why?

Tatu Vanhanen, perhaps best known in the Anglosphere for his co-authorship (with Richard Lynn) of such blockbusters as IQ and Global Inequality and IQ and the Wealth of Nations, has some answers. Vanhanen, inspired by the work of renowned scholars such as Pierre van den Berghe and J. Philippe Rushton, traces the roots of ethnic conflict to the sociobiological theories of inclusive fitness and genetic similarity. Despite vast variation within ethnic groups, members of ethnic groups will, on average, be more closely related to each other than random members of other ethnic groups, making ethnic nepotism an evolutionarily adaptive strategy. Ethnic nepotism is family nepotism writ large; the same process is driven by selfish genes aiding the replication of identical genes resident in related others. Ethnic groups are super-families, though the degree of difference between families varies. Races separated by geography for millennia differ more greatly than more recent cleavages within the Indo-European language-family (for example).

So far, so mainstream – at least in sociobiological terms anyway. The most intriguing aspect of Vanhanen’s introduction was his definition of ethnic conflict. I had been expecting ethnic conflict to be operationalized purely in terms of violence, an expectation aided by the macabre pile of skulls on the front cover. But Vanhanen includes peaceful conflict as well: his model incorporates all forms of intra-nation ethnic division, whether they take the form of political parties politely debating in parliaments, or destructive mobs engaged in ethnic cleansing. His scale has 5 levels: at level 2, for example, political parties or major interest groups are routinely organized along ethnic lines, and some level of discrimination is present. At level 4 discrimination and repression are high and systematic, and there is some serious level of civil warfare or terrorism.

Anyway, after compiling and computing data for 176 nations, Vanhanen reveals that the level of ethnic heterogeneity explains 66% of the variance in the level of ethnic conflicts, the remainder to be explained by other factors and measurement error. The expected relationships between democratization and national income levels and ethnic conflicts exist, but are weak. Intriguingly, he notes that while democratization does not reduce ethnic conflict much, it does tend to reduce violence somewhat; the countries with high levels of ethnic heterogeneity but lower-than-expected levels of strife tend to be either democracies of decent quality or strong autocracies. The two successful recipes for restricting ethnic violence seem to be either democratic institutions specifically adapted to the demands of blood, or the brutality of a hegemonic dictatorship, though obviously the sample sizes for countries with large residuals are not particularly great. Vanhanen also notes that high levels of interracial marriage seem to lead to more stable situations than one might expect, though such a strategy perhaps comes with other costs.

This is just a very brief sketch of Vanhanen’s work, which is well worth exploring in more depth. His nation-by-nation account of the factors that perhaps account for each country’s position on the regression line is fascinating and not something I can do justice to here (so please do buy your copies from Richard Lynn’s Ulster Institute).

As mass immigration irrevocably changes the face of the West, when will it also change our political cultures? Can they adapt to the new and unexpected requirements of sociobiological logic? The implications are intriguing to trace. In the face of declining trust and divergent genetic impulses, can the British constitution – which has until now defied codification – survive? Perhaps the rules of the game will need to be written down in one place in the future – until now we have rather muddled by on trust and precedent. Will institutionalized power-sharing (as in Northern Ireland) become the norm in the West – not between Catholic and Protestant, but between Muslim and non-Muslim (by around 2050 Britain is forecast to be a majority Islamic nation on current birthrate trends)? How much internal resistance will there be to the adaptation of current institutions? How much of the resistance, and counter-resistance, will be violent?

These questions are currently not a significant part of political debate, but Vanhanen’s incisive and clearly written work suggests that perhaps they should. I confidently recommend it in the expectation that many potential readers will derive their own interesting and worthwhile hypotheses from his data and analyses.

so some people have asked me: what about the swiss then? why are they behaving so badly? are they just a bunch of clannish cuckoo clock makers or what?

first of all, everything’s relative. the results of the swiss referendum to curtail immigration were actually reeeally close — just 50.3% voted yes (that was out of a 55.8% voter participation rate) — so it's not like the vast majority of the swiss citizenry want to slow down immigration to their country. and we are only talking here about slowing down immigration to switzerland — the referendum was about reducing the number of people from the e.u. that will be allowed to migrate to switzerland in future — and they haven’t even agreed upon what they’re going to reduce it to yet — it was NOT about ending immigration altogether. nor have the meanie, meanie swiss decided to deport any current immigrants in switzerland or anything like that.

meanwhile, saudi arabia HAS deported 250,000 illegal immigrants in just the last three months — another two million have self-deported since last march when the saudi immigration laws changed — and the saudi government hopes to deport an additional two million over the course of the next year. (they’ve got something like nine million immigrants in the country.) the saudi government will also fine companies that do not meet quotas for hiring saudi citizens — businesses will have to pay a fine for each non-saudi employee they have over and above the number of saudi employees.

it’s hard to become a citizen of switzerland, of course — even non-swiss who are born and raised in the country have to apply for citizenship, and it’s usually the citizens of their respective cantons who vote on whether or not to give applicants citizenship — but it’s next to impossible to become a saudi arabian citizen if your family isn’t/ancestors weren’t saudi. and up until last year, the saudi government made it very difficult for non-saudis to marry saudi women — it’s still not very easy. not so in switzerland. some groups in saudi arabia don’t like and won’t marry — on principle! — other groups in saudi arabia. why the difference in attitude towards foreigners and outsiders in the two countries?

the gdps (the economists’ favorite metric) of the two countries are not all that different (in millions of u.s. dollars): saudi arabia=711,050 and switzerland=631,183 (note that the swiss get there without all that oil). so that’s probably not the problem. a little over 23% of the population in switzerland is comprised of immigrants — the number is ca. 30% for saudi arabia. perhaps the proportionally greater number of immigrants in saudi arabia accounts for the different reactions to immigration in the two countries, but i somehow doubt it. dunno. maybe it’s where the immigrants come from? in saudi arabia, they’ve mostly got immigrants from the indian subcontinent, yemen, and the phillippines. the largest immigrant groups in switzerland consist of people from italy, germany, the former yugoslavia/albania, portugal, and turkey (turks and kurds). so a larger number of immigrants in saudi arabia are from farther-flung places than those in switzerland, but, still, the saudis expelled 800,000 yemenis in the early 1990s, and how different can they be from saudi nationals?

no — there’s a difference in attitude toward foreigners between saudi arabia and switzerland that i think cannot be (completely) accounted for by economic circumstances or how foreign the foreigners are. the swiss want to slow down immigration to their country — the saudis don’t really like you marrying their women! the saudis, imho, are definitely muuuuch less universalistic (see here and here) in their thinking than the swiss.

buuuut the swiss seem maybe to be less universalistic than other western european groups. ‘sup with that? are they more inbred than other western europeans or what?

before i get to that, i should note that the french-speaking areas together with zurich did NOT vote for decreasing immigration as enthusiastically as the german- and italian-speaking regions (h/t daniel olsson! – map source [opens pdf]):

swiss referendum map 02

as mario on twitter pointed out, there are more immigrants in the french-speaking cantons and zurich (ca. 25% foreign born) than other areas of the country — from the telegraph:

“Interestingly, those areas with the most immigrants, and therefore with the most overcrowding, typically voted against the proposals.”

it could very well be that foreign born swiss citizens tended to vote against this proposal — someone ought to check. anecdata: i have a cousin who is a naturalized swiss citizen, and she voted against the proposal. (see? what do i keep saying? gotta be careful with letting in immigrants!)

anyway…i have some notes on switzerland and the swiss, but don’t have a complete picture of the history of their mating patterns (yet). here’s what i’ve got so far…

in late antiquity, the gallic helvetii inhabited the swiss plateau — no idea what their mating patterns or social structures were like — and, of course, the romans were present. some people in switzerland were christians already by the early 300s a.d., but remember that the first of the church’s cousin marriage bans didn’t appear until the early 500s a.d.

with the collapse of rome, the burgundians moved into western switzerland and the alemanni into the north onto that plateau. again, don’t know anything specific about the mating patterns/social structures of either of these groups, but seeing as they were germanic populations, it’s likely that they had similar mating patterns/social structures to the other germanic groups: some amount of cousin marriage, residential nuclear families, and bilateral kindreds that were of import in everyday life and, most especially, in legal issues including wergeld payments and feuding (see the links under “germans” in the “mating patterns in europe series” below ↓ in left-hand column for more info).

the alemanni and burgundians were conquered by the franks in the early part of the sixth century, and presumably the franks would’ve tried to impose their ideas on marriage in their new dominions and/or the burgundians and alemanni might’ve wanted to imitate their new overlords. avoiding cousin marriage may not have been part of that package right away, though — recall that, although the church banned cousin marriage in 506 a.d., the frankish king didn’t issue a secular law banning cousin marriage until sometime in the 750s, but then by the 800s the franks thought it (heh) barbaric to marry even a second cousin (see this post). how well this law was enforced outside the frankish heartland in north/northeastern france — or if it even applied throughout all of the frankish kingdom(s) — i don’t know. i would think it likely that, whatever the case, the pressure to avoid cousin marriage would’ve been strongest in the core areas of the frankish kingdom(s) — austrasia and neustria in northern and northeastern france — since that’s where the practice really got going the earliest, and that the degrees of pressure and/or enforcement would’ve been weaker the farther one moved away from that core — but i could be wrong about that. additionally, the alpine regions of switzerland simply never would have experienced manorialism, a system in which enforcement of the cousin marriage bans was made easier (lords of the manor often had to approve marriages, plus there were typically churches/ecclesiastical-types attached to manors) and which pushed for nuclear family units.

fast-forward to the reformation (i told you i didn’t have the complete picture!) — one of the outcomes of the reformation was that many of the new protestant nations/churches reversed the catholic church’s cousin marriage bans — cousin marriage is not prohibited anywhere in the bible, so many of the reformers just threw the bans out (plus they were also disgusted with the church charging for dispensations as they were with the indulgences). however, in the 1500s (1530s), many cities and cantons in switzerland actually reinstated the cousin marriage bans — zurich, bern, basel, schaffenhaussen, saint gallen. geneva had never done away with them. the tide changed again, though, beginning in the 1600s, and over the course of the next couple hundred years, the bans on cousin marriage were gradually lifted. from “Kin Marriages: Trends and Interpretations from the Swiss Example” by jon mathiue in Kinship In Europe: Approaches to Long-Term Development, 1300-1900 (2007) [pgs. 214, 215, 224, and 216]:

“After an especially conservative phase in the late sixteenth century, the rolling back of the prohibitions emerged as the dominant trend, similar to that in the German lands….

“Thus, except for the canon rules, which for Catholics remained valid in their religious existence, the familial marriage prohibitions were rolled back three degrees over the course of 350 years….

Around 1500, one could only marry his fourth cousin; by 1900, first cousins were acceptable as marriage partners. The dispensations for forbidden kin marriages, documented in local and central records, show a parallel development. They increased practically everywhere, and especially in the eighteenth and nineteenth centuries, became a common occurrence….

“That the lawmakers repealed the restrictions despite every counterargument is thanks not just to the new relationship between state, church, and citizen, which had developed since the revolution. Earlier juristic practice had already had to take into consideration the values of the populace to some extent, and here it appears that large groups surmounted their aversion to kin marriages, because they were increasingly interested in marrying their kin.”

so, at the same time that the secular and canon laws against cousin marriage were being relaxed in the country, swiss roman catholics were, additionally, applying for greater numbers of dispensations from the church to marry cousins. here is table 11.1 from “Kin Marriages: Trends and Interpretations from the Swiss Example”. the number before the slash (/) in each instance is the percentage of marriages up to and including third cousins; the number after the slash, the percentage of marriages up to and including second cousins. you can see that there was a general increase in the percentage of first and second cousin marriages in all of the locales over the time period. of course, the rates don’t come anywhere near the rates of first and second cousin marriage in saudi arabia today (50%+), but the third cousin rates seem quite high to me [pg. 217 – click on table for LARGER views]:

switzerland - mathieu - table 11.1

by way of comparison, many of the first and second cousin marriage rates in the 1800s are higher than those for the same time period in southern england, and the third cousin marriage rates are MUCH higher. for southern england, the rates were: first cousins=2.2%, second cousins=1.7%, third cousins=2.2%. the swiss rates are more like rates seen in parts of scotland (see also the other rates in the table in that post).

an isonymic study (not as great as a genetics study, but hey — you work with what you’ve got) of a sample of 1.7 million swiss individuals conducted in 1994 found that (links added by me):

“…the highest consanguinity values were observed in the Grisons and in the nucleus of the founding Cantons [see map here – h.chick], while the lowest were observed in the Cantons of Geneva and Vaud, preferential areas of immigration to Switzerland from abroad…. French and Italian languages indicate minor, German and Romanisch major inbreeding.

i said before in my post the radical reformation that my guess is that the swiss are some of western europe’s “inbetweeners” as far as outbreeding goes. i guessed that they probably got involved in The Outbreeding Project later than some other western europeans — the ones in and closer to the center of my “core” europe. and they didn’t experience manorialism either (unless some of them on the swiss plateau did?). the fact that the swiss were a bit late on the medieval reduction of internal violence in the country — as compared to the english, dutch, and belgians anyway — but were ahead of the italians on this score — is an indicator that they are inbetweeners, i think.

on reviewing the evidence that i’ve collected so far, what it in fact looks like is that, yes, the swiss may indeed have started outbreeding a bit late — possibly a bit later than the franks in the frankish heartland who were seriously outbreeding by the 800s — but, then, in addition to the late start, it looks like the swiss outbreeding project went into reverse in the 1600s. not extremely so — they didn’t resume marrying their cousins at rates that the arabs do today, or not even like the southern italians of the 1960s, but something along the lines of some of the scots in the 1800s.

so perhaps the swiss are inbetweeners BOTH because they started outbreeding a bit late (900s? 1000s?) AND because they resumed inbreeding again — somewhat — about four hundred years ago.

anyway…more on the swiss anon!

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.

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.”

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.

‘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!

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….
