PAPER REVIEW

Kong, Augustine et al. – 2016 – Selection against variants in the genome associated with educational attainment


marker

This paper makes the case that there has been a decline in the prevalence of genes increasing propensity for more education (POLY EDU) in Iceland from 1910-1975.

polyEDU-fertility

Here are some of the key points:

  • The main mechanism was greater age at first child, not total number of children (i.e. the clever are breeding more slowly).
  • As in many such studies, the effect is stronger for women.
  • One allele associated with more children and having them earlier also tags a haplotype associated with “reduced intercranial volume” and neuroticism: “… thus a striking case where a variant associated with a phenotype typically regarded as unfavorable could nonetheless be also associated with increased “ fitness” in the evolutionary sense.
  • The decrease in POLY EDU prevalence was faster earlier this century, but this is an artifact of the higher survival schedules of people with a higher propensity for education (i.e. tying in with the well known finding that higher IQ is associated with higher life expectancy). The decline from 1940 onwards becomes linear, and is a better measure of estimating the change of the average polygenic score over time.
  • It is estimated that is POLY EDU declining by 0.010 SUs per decade, but this rises to 0.028 SUs per decade because the measure captures only a fraction of the full genetic component of education attainment (POLY FULL).
  • The trends in POLY FULL are estimated to be causing a decline of 0.30 IQ points per decade.
  • The authors note that this has entirely canceled out and then some by the Flynn effect, but it could still have “a very substantial effect if the trend persists for centuries.”

Many other studies indicate that the FLynn effect has ended or gone into reverse across the developed world around the 2000s by the latest.

If it’s a permanent plateau, we could be seeing 3 IQ point declines per century. Extend that out for two or three centuries, add some more Third World immigration, and you get the 1 S.D. IQ decline that I posited for the Age of Malthusian Industrialism aka the business as usual scenario.

 

Now that we have established that immigration is not much good, let’s take a look at another component undergirding our transition to Idiocracy – the differential fertility rates of different IQ groups.

This is a highly contentious topic, and not just on account of the usual political kurfuffles, but also on real disagreements as to its actual extent. Psychologists such as Richard Lynn, Edward Dutton, and Michael Woodley are pessimistic (Woodley 2014; Dutton et al. 2016). OTOH, JayMan has argued based on WORDSUM analysis that “Idiocracy can Wait.” This topic is extra difficult because you also have to disentangle the dysgenics trend from the Flynn effect that has raised IQs in the developed by about 10 points during the 20th century.

The PISA Data Explorer is truly an invaluable tool for bringing the light of cold, hard facts on these issues.

While playing around with it, I noticed you can select the variable “same age siblings,” which ranges from zero to ten. Zero siblings implies, of course, that the student in question is an only child; by definition, the survey excludes entirely the childless portion of the population, which is also its brightest. Data only exists for the Mathematics part of PISA 2000, but it is more than enough to get an idea of the general trend – and as you might expect, it’s not a very good one.

I calculated the “slope” in terms of PISA-adjusted IQ points lost per additional sibling for the first four siblings (in practice, since TFR <<6 for all countries in PISA 2000, the IQ of children from even larger families won’t have much of an effect). See the table at the bottom of this post.

Here are some general points to take away:

(1) Indonesia is the only country, at least as judged from the Math portion of PISA 2000, that has eugenic fertility patterns (since its a developing country with a TFR = c.2.5, we can be pretty sure that childlessness will not impact these statistics down by very much since its simply very rare). Second is Thailand. Both are lower-middle income Asian countries that only escaped the Malthusian trap within living memory and are in the middle stages of the demographic transition. (That said, in PISA 2015, coverage of the 15 year old population was not great in either country – 68% in Indonesia, 71% in Thailand – and assuming that was also generally true in 2000, those not turning up are sure to be less bright and will probably come from more rural, bigger families).

[Epistemic status: Speculative]. However, despite also being within the middle-income brackets, the Latin American countries have moderately dysgenic fertility patterns. I wonder if this could explain Steve Sailer’s observation that Latin American countries seem to have smaller smart fractions than Middle Eastern ones, despite similar average IQs. Maybe their European and, critically, Europeanized, upper classes have simply failed to reproduce in the last couple of generations?

(2) The East Asian and European Nordic states have more eugenic fertility patterns. The European Mediterranean – Greece, Italy, Romania, Portugal, Bulgaria – has some of the worst. France, Spain, Brazil, the UK, Germany, Poland, Russia, and the US all cluster close to each other (though American White fertility is probably more eugenic, perhaps around Australia’s and Canada’s level, since minority and especially Black fertility patterns are known to be highly dysgenic even according to JayMan’s optimistic analysis).

(3) The rate of childlessness is considerably lower, at around 10%, in the ex-Soviet bloc and East-Central Europe than in Western Europe and the US.

childlessness-by-country

This means that their real figures will get a modest boost relative to those of Western Europe, since not as big a percentage of the professional class are getting cut out entirely.

(4) You can’t precisely quantify the dysgenic impact from this with any exactitude, since you’ll also need to combine it far more detailed fertility data.

That data does exist, at least for many of the OECD countries and Russia, so its doable, but it would be a pretty big project.

(5) Eyeballing it there seems to be a moderate degree of correlation with commenter Cicerone’s country estimates of dysgenic fertility extracted from fertility data of educational classes.

The Flynn effect has reversed in terms of spatial IQ, according to a big recent meta-study by Jakob Pietschnig and Georg Gittler.

James Thompson has a good summary in Deutschland über alles, dann unter allen?

In the present meta-analysis, we show an inverse u-shaped trajectory of IQ test performance changes in a large number of samples (k = 96; N = 13,172) on a well known test for spatial perception (the three-dimensional cubes test, 3DC) in German-speaking countries over 38 years (1977–2014). Assessment of both item response theory-based measures as well as more standard measures of classical test theory showed initial increases and a subsequent decrease of performance when controlling for age, sample type (general population vs. mixed samples vs. university students) and sex. Our results suggest saturation and diminishing returns of IQ increasing factors (e.g., life history speed) whilst negative associations of IQ changes with psychometric g may have led to the observed IQ score decrease in more recent years.

Below is the version of the graph that has been corrected for age, sex, and sample time. The all time peak seems to have occured around the mid-1990s.

germany-flynn-reversal-iq-pietschnig-gittler

The PISA tests have indicated that (ethnic) Germans might have some of the highest IQs in Europe. This is credible in light of their historical intellectual accomplishments in the 19th century through to the 1930s, even though Germans were typically shorter (i.e. probably less well fed) and certainly poorer per capita than the British. The Finns are brighter on average, but have a small standard deviation, hence much fewer geniuses.

However, I suspect that since the 1920s and certainly since the 1970s German fertility has become strongly dysgenic. This has started outrunning the benefits from better nutrition (essentially maxed out by the 1970s) and more intensive schooling. Furthermore, they have been brought down by immigrants, to the extent that in 2012 Germany as a whole was overtaken by Poland in the PISA tests.

Further from Pietschnig & Gittler:

Results from our linear regression analyses suggest decreases of about 4.8 IQ points per decade when controlling for age, sample type, and sex, thus indicating a substantial negative Flynn effect that is even stronger compared to previously observed positive trends (e.g., Flynn, 1984, 1987; Pietschnig & Voracek, 2015). This trend was observed in linear regression analyses, but our results showed that the present changes over time may be even better described as a curvilinear function, thus indicating initial increases, followed by stagnation (with performance peaking around the mid-1990s), and subsequent decreases of task performance.

Incidentally, this is one of the factors you have to bear in mind when looking at historical “human accomplishment” (in science, literature, art, etc) and the puzzle of why East Asians don’t figure largely in it for all their high IQs. Not only were the key countries – UK, Germany, etc – well ahead of the likes of China and Japan in terms of nutrition (related to IQ) and general development (schooling, funding for science) but they also enjoyed a bonus from not yet having fallen on the dysgenic slope. I suspect this will likely remove any need for Jaymannian “clannishness” as a key explanatory factor.

But I digress; this is for another post.

Back to Germany – if you are in the throes of dysgenic decline, you might want to try to at least do some obvious things to slow it down, like not take in millions of 85 IQ Third World immigrants. Obviously this is not happening but I found it curious that the great scientist Heiner Rindermann has been given column space to call for exactly that in the German magazine Focus.

In it, he makes some of the following points:

  • Unlike the case of the Huguenots, whom the Elector Friedrich Wilhelm welcomed to Prussia in 1685, the wave of immigrants in the past years and months are lacking in human capital.
  • They perform at ~110 points below US and German standards in the PISA tests, or a difference of three years in terms of schooling age. The gap with Africa is more like four and a half years.
  • Even “elite” students like engineering students from the Gulf states are two to four years behind their German counterparts.
  • A recent study in Chemnitz, the city that hosts Rindermann’s university, showed that asylum seekers with university degrees had an average IQ of 93 – that is equivalent to that of Realschule students, i.e. prole children.
  • He mentions that this gap is not closed in the second generation, and even dares to mention cousin marriage as a contributory factor.
  • These groups will have higher unemployment, and their cognitive errors in daily life such as in traffic or professional decisions will negatively impact other people.
  • HE ACTUALLY GOES THERE and mentions the high incidence of violence against dissenters and sexual assaults in places where they congregate, such as immigrant neighborhoods and the refugee camps. He also mentions the statistic that whereas only 12% of the French population are Muslim they constitute 60% of the prison population, and alludes to the Rotherham mass rapes in Britain.
  • Diversity is associated with more crime and inequality, contrary to the positive rhetoric around it.

Furthermore, the comments to his article are generally positive.

Given the current climate, in which Angela Merkel openly demands that Mark Zuckerberg censor “hate” against immigrants on Facebook and the New York Times approving quotes a former East German apparatchik openly commiserating that anti-immigration activists from a village getting swamped by Third World immigrants are not getting arrested, I will admit to some degree of surprise that Rindermann was allowed his not very PC say. I hope he doesn’t get into trouble on account of this.
