Ansbach bomber pledged allegiance to ISIL

 

An hour is a long time in politics. The Ansbach bomber/failed asylum seeker has apparently been found, via his mobile phone, to have pledged alliance to Islamic State.

Bavarian Interior Minister Joachim Herrmann said the man, who has not been named, also "announced an act of revenge against Germans because they were standing in the way of Islam".

Herrmann said violent videos and bomb-making material were also found at the man's home in the Bavarian town of Ansbach.

Islam calling: a torrent

It is hard to keep up with the news these days. I recall the remark attributed to Lenin: There are decades when nothing happens, and weeks when decades happen.

Under the direction of Chancellor Merkel, Germany made the decision to admit over one million refugees. They were described as Syrian refugees, but like everything else in this story, this is probably factually incorrect. The entrants were not all of them or most of them Syrians, and they were not all of them or most of them refugees. According to journalists who looked at the passports being dumped at the border, many of the entrants were from Pakistan, a country not currently at war, other than endemically with itself. They had one thing in common: they wanted to go to Germany, and the German Chancellor had invited them. Many Germans welcomed them.

In this account I will do my best to keep up with recent events, and keep up with the varying accounts given of the perpetrators and their motives.

On 18 July we had an axe and knife rampage by what was described as an Afghan teenager shouting Allahu Akbar, who left several train passengers with severe wounds, and after running from the train later attacked two old ladies walking their dogs, injuring one of them. His obligatory YouTube testament revealed him to be a rather large and well-built young man, and his accent was said to be Pakistani.

On 22 July an Iranian teenager born in Germany went on shooting rampage in Munich, killing nine people, many of them migrants, before shooting himself. Witnesses reported that during his rampage he said “I am German”. The first accounts were of a depressed boy, complaining of being bullied, and said to have been obsessed with school shootings. Early reports said he was linked to the right-wing Norwegian Breivik, but now the Police say no manifesto from that murderer has been found in his room. Why the specific reference was made is unclear. Another boy who spoke to his before his rampage and knew he had a gun has now been arrested.

On 24 July what was described as a Syrian asylum seeker was arrested in the town of Reutlingen, Baden-Wuerttemberg, after killing a Polish woman with a machete or meat cleaver and injuring two other people before a driver knocked him down with his car, probably thus avoiding a far greater number of casualties.  Police have come up with the preliminary hypothesis that it was a crime of passion, because the Polish woman was pregnant, and was known to the asylum seeker. Unlike others, I make no claim that the perpetrator was Syrian and an asylum seeker, nor that he was in a reciprocated passionate relationship. He committed his murder and other attempted murders yesterday, so we haven’t yet seen his Facebook pages, Twitter feeds and YouTube declarations. He has a swarthy complexion and a beard, but I cannot judge from that whether he is in possession of a German passport.

On 24 July, what is described as a failed Syrian asylum seeker blows himself up in the small Bavarian town of Ansbach, injuring 12 other people, 3 very seriously. He had been turned away from a music festival because he did not have a ticket, so strolled down to a local bar. If he is a failed asylum seeker it seems that failing to get asylum (apparently he was turned down a year ago) is no bar to living in Germany and murdering its citizens, so I cannot currently attach much significance to him being a “failed” asylum seeker. Equally, I cannot vouch for him being Syrian. Anyway, something irritated him, so at least 12 have been injured by a bomb in a backpack with metal shavings packed round it. The assailant, named locally as Mohammed Daleel, was already known to police for possession of drugs and had also spent time in a psychiatric facility having attempted suicide on two occasions in the past. Residents at the man's asylum shelter described him as a 'lying attention seeker'. I cannot vouch for any of these descriptions.

As discussed in previous posts, there are distal and proximal explanations for human behaviours, but some patterns in these events can be detected if you know how to look: so far, none of these crimes have been committed by Germans, that is Germans with German parents and German grand-parents and German great-grand-parents. So far, those sorts of Germans have not being rampaging and saying that their god is the greatest. Not so far, though in the first half of the 20th Century they had a tendency to stray over other people’s borders.

The oxygen of publicity is drawing in larger numbers. A dangerous Jihadist meme has generalised and gained traction among the disaffected, who now feel validated in taking others to their deaths, for 15 seconds of fame.

At times like these there is a natural tendency to stay in one’s study and read improving literature. Rather than rush out into the street screaming or waving a bladed implement, I have been re-reading an opinion piece written last year by my colleague Prof Heiner Rindermann, which I reproduce in rough translation below:

Rindermann, H. (2015). Engineers to secondary school level. The standard of education of most immigrants from Western Asia and Africa is low, their capabilities are limited. The consequences will be bitter. Focus, 23 (43), 42-44.

In 1685, the Elector Friedrich Wilhelm gave asylum to the Huguenots persecuted by Prussia, a wise decision: For centuries the positive influence of the Protestant refugees has been recognized. Thus, the Humboldt brothers were instrumental in the development of local science. In cities, the economic productivity was higher, the more Huguenots lived in them. The achievement of the de Maizière family, for example, shows the wise decision made 300 years ago.

The Huguenots brought with them skills and attitudes and they reproduced through generations. The human capital approach applies this perspective to all countries: The better the human capital, the more prosperity and freedom, democracy and the rule of law, innovation, equality and social peace are there in those countries. In this context, how should we assess recent German immigration policy?


For years, and in recent months increasingly, there are many immigrants coming from South-East Europe, Middle East and Africa. The majority of them do not have high qualifications: In international university studies, the average results of these countries are at 400 points, which is more than 110 points less than in the US or Germany, which corresponds to approximately three years of schooling competence difference. Even greater is the gap with Africa with four and a half years gap in some schools. Student assessment studies in Europe show for immigrant children compared with their countries of origin somewhat more favourable results. However, the difference is still several years of school.


Even in an elite group, engineering students from the Gulf states, a great difference can be seen: Their skills are in the average range much lower than poorer Vietnamese, but two to four school years behind those of German engineering students. This pattern of results underpinned a recent study
in Chemnitz: asylum seekers with university studies presented in mathematical and figural tasks an average IQ of 93 equivalent to the skill level of local elementary and secondary students.


Of course, migrants have opportunities for development, but the experience with recent generations of students of foreign students shows that these opportunities are limited. The often mentioned problem of language is only secondary, the much more serious and momentous problems are basic skills weaknesses.

In school, these migrants will show weaker performance on average and rarely achieve high qualifications. The problem is exacerbated by the practice (frequent in Muslim communities and in Africa) of cousin marriage with corresponding impairments.

The unemployment rate will be higher, and requests for social assistance more frequent. These people will cope with the technological and cultural complexity of a modern country less
successfully. Cognitive errors in daily life, such as in traffic or in professional and financial decisions are more common, with consequences for others.

Migrant groups will interpret their experiences as discriminatory. In order to overlook such differences some companies may accept lower standards without admitting it, and may avoid the use of objective performance tests. Some financial businesses may be pressured to award more favourable loans and insurance premiums than objective measures would warrant. One way to deal with the lower scholastic ability of immigrant communities, a cause of frustration to them, it to seek alternative activities, such as sports or music. However, there are also dysfunctional issues leading to crime.

Internal factors, such as found in the culture and the practice of Islam in the country of origin, also play an important role. A variety of reports on violence within immigrant families, compared to other migrants,women, locals, political opponents and dissenters, in refugee camps, including sexual assault, sometimes in the form of eruptive violence of whole neighbourhoods, suggest significantly higher aggressiveness  in these immigrant groups.


According to official reports Muslims, although they represent only 12 percent of the population of France account for 60 percent of all prison inmates. In Belgium, Muslims are represented eight times more commonly,  in the Netherlands and Great Britain four times. In England more than 1,000
British girls were sexually abused by migrants from Pakistan. In Berlin immigrants are over-represented more than three times of violent crimes, in rape cases more than sevenfold.
Of course, people who violate the law within the migrant communities constitute a minority, and every offender behaves for the vast period of his life in a generally compliant manner!

But even rare exceptions cause extreme stress for others. To monitor a single Islamists, 20 to 30 police officers are necessary. A murder, expressed in monetary units which are certainly insufficient, causes a loss of several million, a rape of several hundred thousand and a theft of several thousand euros.

Through migration, often positively evaluated as a good thing, diversity increases. But on a societal level, higher diversity is associated with more income inequality, state fragility, higher crime rates and with less social trust.

For many people these effects of migration policy might be surprising or even disturbing. The reason is that politicians, and the media represent different interest groups. Decisions such as the policy of open doors of Angela Merkel may lead to unintended consequences for society. As the benefits and risks of open doors are distributed among different people and long periods of time, some reap the benefits of political reputational  gain immediately, while the cost will be borne by others for decades to centuries, in particular the relatively poorer classes including many less recent immigrants. The freedom and the everyday level of women will be more limited. The same applies to Jews, homosexuals, cartoonists or critical intellectuals like Salman Rushdie or Ayaan Hirsi Ali.

The professional life of police officers, judicial officials and staff in employment offices, even the firemen, teachers, doctors and paramedics, will be more difficult and risky.

The effects of letting in the Huguenots can be seen as a wise decision 300 years later. Merkel’s less wise decision will also have visible effects in 300 years time. 

Postscript.

Heiner’s university colleagues sought to haul him up before the University authorities to face the usual charges, but he answered them by suggesting a debate in which his critics pointed out any factually incorrect statement he had made in his opinion piece. They have not taken up the challenge.

Seen in the light of recent events his prognostications seem to be on the mild side.

St Petersburg calling: The Gottfredson Bell Curve

 

Linda

 

 

If, despite her having made so may contributions to intelligence research, Linda Gottfredson had to be remembered for only one thing,  I think it would be for her exposition of the meaning of intelligence in everyday life.

Whereas most previous researchers talked about the abstract concept of intellectual power, and gave examples only in terms of academic qualifications, Linda looked at the practical impacts of ability on trainability and the successful completion of everyday tasks. Even among my clinical psychology colleagues, most of whom who had done lots of intelligence testing, her papers were received with enthusiasm and some amazement. She explained what people could do at all levels of intelligence, in a way that made sense to patients and clinicians alike.

Some people are brighter than others. This is the finding which has emerged from intelligence research over a century. Read Linda Gottfredson  “Why g Matters: The Complexity of Everyday Life” (1997) if only just page 117 for an explanation of the relationship between literacy, learning and intelligence.

http://www.udel.edu/educ/gottfredson/reprints/1997whygmatters.pdf

The video below shows David Lubinski talking to Linda for her Distinguished Contributor Interview.

https://www.youtube.com/watch?v=I1E6ayVcPks

 

At 14 minutes she talks about the meaning of g, general intelligence. She recalls the three things that are required to detect g, according to Hunter and Schmidt: reliable measures, no restriction in the range of intelligence, and no sampling errors.

As a consequence of some people being brighter than others, and some jobs being more complex than others “You cannot have equality and excellence too”.

At 24 minutes she talks about the real tasks that people can or cannot do according to their intelligence levels.

At 35 minutes she describes how she came to write the statement on intelligence for the Wall Street Journal that was signed by 50 leading intelligence researchers in 1994. She said she kept it simple, and just summarised the main findings in the literature, and asked them to sign or not, not allowing them to change a word.

At 42 minutes she explains why intelligence is so important in health care: prevention requires a high level of self-care, and in the case of modern medicine, that turns out to be complicated. The dull are dying before their time, because the cannot follow the instructions for self-care.

At 57 minutes she mentions The Mind’s Eye: the capacity of intelligent people to imagine to imagine hypotheticals, and evaluate them.

At 1:07 why g matters, at 1.12 her admiration for Arthur Jensen, at 1.31 the contortions that some test creators have got into when trying to build a valid test which also annuls racial differences, mostly by complicated cheating (for example, restricting the cognitive elements of the test to being able to read at the 1st percentile).

A summary of a lifetime’s contribution, gracefully done by a researcher who suffered harassment for daring to talk about intelligence.

Islam calling: Distal and proximal

 

Blood stains are seen on the regional train on which a man allegedly wielding an axe attacked passengers in Wuerzburg, Germany

 

Correlations are indicative of possible causes, but not definitive. In the modern way, we now have a torrent of information about the perpetrator of the Nice massacre. The quality of that information varies considerably.

Neighbours have spoken variously of him being:

a normal person, just like others in the neighbourhood, and doing normal things like drinking and going to parties;

a weird person; who looked odd, would not hold doors open for others, and was asocial and a bit scary.

Conflicting reports of this sort are pretty usual. Ordinary social behaviour has some common ground rules, of which non-involvement is a large part. Many people do not know much about their neighbours. In ghettoes like the one in Nice there are incentives to say nothing, and to have seen nothing. Interviews off camera are probably more informative, free from possible community retaliation.

His family have said that he had a long psychiatric history including treatment for schizophrenia. Other family members have said that he had recently sent them £84,000 which is a substantial sum for a divorced truck driver with an estranged family to keep.

His mobile phone has revealed a string of female and male sexual contacts, with many admiring selfie photos. His main homosexual lover, a man in his 70s, has been identified. The perpetrator’s texts have led Police to a suspected small arms provider and to other contacts.

Video surveillance from street cameras showed that he practiced taking his truck down the route he used for his rampage, and photographed the route. He hired the truck some days earlier, and also acquired weapons. Other witnesses said they had seen the truck, being driven erratically half an hour before the attack. Apparently he sent some text messages in that half hour of waiting. He gained entry through the police cordon by claiming to be delivering ice-cream. Overall, it was not a spur of the moment act, but carefully considered.

At this point some commentators are tempted to jump to conclusions: conflicted gay murderer; schizophrenic murderer (5 times more likely to be violent than non-schizophrenics); both gay and schizophrenic; depressed after his divorce; not depressed but in a whirl of sexual promiscuity, or polymorphous perversity as Freud called it; suicide by cops; or “very rapidly radicalised” as a French government minister surmised, which recent reports put at a mere 8 days. All possibly true.

However, the general distal explanations do not really show why he committed mass murder. They fit better with a lonely suicide bid (the depression angle) or a deranged random stabbing of passers-by (the psychotic episode angle), not a planned mass murder. The particular method he used involved him seeing the people he murdered at first hand, and feeling the truck rise and fall as he went over their bodies. It was close and personal and protracted.

In trying to find out why he murdered we have a long list of possible distal causes: North African genes, Tunisian culture, previous criminal behaviour, low ability, confused sexuality and particularly conflicted homosexuality, and persistent propaganda from Jihadists about the need to attack infidels. More recently he had a divorce from his wife (more than a year ago I think) and then most recently whatever was happening on Jihadist websites or contacts or friendship groups. He has been claimed by ISIL as one of their soldiers, and this is a reliable guide, according to those who study these matters. However, I would not bank on this unless a real link is proved in later investigations. (In a sense their real claim is: “We inspire people to violence, without knowing who they are”.)

The act was terrorism on a large scale, and each distal cause increased the probability that a proximate cause would lead him to his performance: attacking French civilians on their national day. Whatever the personal shortcomings of the perpetrator, he terrorised France, which is what the Jihadist cause required him to do. Their aim is to show Europeans they are unwelcome in their own countries.

Yesterday a 17 year old Afghan refugee to Germany, given government support and fostered by a German family for two weeks, has attacked passengers in a train with an axe and a knife, leaving a blood-splattered carriage with three very seriously injured passengers and 14 in a state of shock. He had shouted Allahu akbar" ("God is great"), a witness said. In his bedroom Police have found a home-made Islamic State flag.

ISIL has also claimed this attack: "The perpetrator of the stabbing attack in Germany was one of the fighters of the Islamic State and carried out the operation in answer to the calls to target the countries of the coalition fighting the Islamic State”. Apparently this is a more “arm’s length” endorsement.

Distal causes: Afghan genes and culture and (the Facebook rest will be filled in quickly, I presume, his website history will take a bit longer). Proximate cause: ISIL?

The perpetrators have a common theme: they have been convinced that they should kill the citizens of the countries which took them in. The most obvious ultimate cause of their violence is The Cause they espouse.

Islam calling: troublesome minorities

 

Minorities trouble in two main ways: by being a nuisance and by becoming majorities. Doing both in parallel is the greatest threat to the host nation.

Proportionality is the key here: in most places, most people, most of the time,  go about their business peaceably. They can rightly say of the troublemakers in their communities that “they are a minority”. True. However, those troublemakers are more frequent in some communities than others, and this is a subtlety that often gets lost in discussion. Troublemakers need some support from their own communities, even if just tacitly turning a blind eye.

The rate at which European communities commit mass murder of their own citizens is very low, though not zero. The US suffered casualties from anti-government bombers. The UK suffered more casualties from Irish Republicans. Basque separatists have bombed Spaniards. However, these dreadful events can be seen as localised grievances, not an over-arching plan.

What troubles most about the Jihadist meme is its generality: its scope is global, and although it has key Western targets, the Crusaders, it takes on all non-believers: white Europeans, Black Nigerians, and anyone else who gets in their way, including brands of Islamic belief they judge to be insufficiently pure.

Like any franchise, it attracts lone entrepreneurs: those who vaguely want to do something, and find a general plan excuse enough to vent anger, disappointment, and general malaise. Insurrections are begun by dreamers and implemented by criminals.

So now we have a dreadful calculus: Western Europe has sizeable Islamic populations, most of whom are not bent on committing murder. Within those populations there are a minority willing to murder on a large scale. Their spectaculars (as the IRA used to boastfully call them) are aimed at showing the population that their governments cannot protect them. They attack the presumption of safety on which civil society is based.

A nation is a protection system, and not a racket if you can leave of your own free will. In exchange for following the rules and paying your dues you get the protection of the state: the protection of borders and the protection of your safety within the boundaries of the state. Insurrections challenge that protection, and taunt both the governed and the government.

The paradox comes thus: any state which guarantees the rights of citizens must also grant them to those who would destroy the state and injure its people. Our interpretation of Magna Carta is that the big letter demands that no-one be arrested without due cause. A noble aim, though of course the original did not apply to all citizens, only to free men, say about 40% of the population at most. It did not contemplate millions of non-Christian non-Europeans, with perhaps 10% of them at least passively in favour of establishing the dominion of another religion and another system of law. That which would have been considered treason is now considered a right which must be defended by the very State which is the target of the attack.

The current European plan, avidly followed in Nice to deal with its sizeable Muslim population (in its own run-down, poor neighbourhood) is to try to spot the militant tendency as early as possible, and bring help, counselling and Police attention to those most likely to commit murder. It may have worked to some extent, but not sufficiently strongly to prevent a large number of volunteers to the global cause going off to do some beheading in Syria, and at least one depressed individual from planning to crush his fellow French citizens to death under the wheels of his truck.

The current plan will continue, I presume, as a careful calculation, that the Muslim minority must not be provoked into turning further against European states, but must be cajoled, convinced, and sometimes bribed to bring information to the Police. Hardest of all will be to explain to Muslims that Muslims in Europe are not poor because Europeans are nasty to them, but mostly because their skills, abilities, and educational achievements, though perhaps a bit higher than in their countries of origin, are not at European levels. European elites baulk at explaining that, and so are caught in a vicious circle of apology. They have assumed that all men are equal, and cannot concede that that is an ideal to which States pay homage (the French particularly, since they count all as Citizens without “noticing” origins) but which does not reflect reality.

So, the plan is for Europe to take casualties, often in very large numbers in very public spectacular executions, and hope that the ideals of the brotherhood of man will win through in the end. In the meantime the pernicious meme will be propagated to all believers: you are urged to kill the infidel by all means possible.

In historical terms, the dilemma is whether it is 1914 or 1939, the former being (according to one school of thought) a time when better diplomacy could have prevented war, the latter being a time when willingness to go to war could have preserved the peace. Perhaps neither war is the appropriate comparison point, and we need to go back as far as the siege of Vienna.

Islam calling: lorry attack in Nice

 

Police have identified the perpetrator of an attack in Nice, France, who has killed at least 84 people attending a 14th July firework display.

The perpetrator had weapons and hand grenades in the back of his truck.

Naturally, there is interest in who this person was. An Islamic petty criminal, known to the Police but apparently not to the security services.

In predicting intelligence we are guided by the indifference of the indicator. Any test will do, formal or informal, if it reliably distinguishes one person from another, and has real life predictive value.

In predicting mass violence we should also follow the indifference of the indicator. Muslim men, probably with a criminal background, watching lots of jihadi videos and sermons, recently becoming devout, and probably subject to some random change in personal circumstances which would otherwise not be significant. Noisy data, and hard to find the signal in time to do anything about it. More potential perpetrators than there are teams to follow them.

President Hollande has just told France they will have to get used to terrorist attacks. It would be good to have a Plan B.

 

 

Is St Petersburg Russia’s Disneyland?

 

In former times this would get me sent to the Gulag, but is St Petersburg Russia’s Disneyland? Intended to ape Versailles, Venice, and more generally the Western wonders of the world, it succeeded in showing Russia to advantage, and the West to Russians: an accomplishment in all ways. Perhaps every culture wants a magic castle: Russia got St Petersburg and the US got Disneyland. The key may be to start construction in 1703.

The ISIR conference brochure shows a young Lev Vygotsky, together with Luria probably the Russian psychologist best known to the West. Good to put a face to a classic figure, and a cue for a story of his I cherish: a peasant hearing two astronomers discussing distant stars one night was amazed, not that they knew the stars’ distances and types, but that they knew their names.

A conference is a grand place to know Names at close first hand, over many coffees. More details about the conference can be found here:

 http://www.isironline.org/wp-content/uploads/2016/07/ISIR-2016_full_programme.pdf

or just follow the hashtag #isir16 on Twitter.

Also very good to see a page in memory of Earl “Buz” Hunt. I can testify to the immense pains he took to improve papers he reviewed, saying “If I can find errors by spending 15 minutes on Google it would be best if the author reviewed his work again before anyone else sees it”. The obituaries did not exactly say so, but he was pretty tough-minded but admired for his forthright opinions. He tolerated me even when we differed, for which I am grateful.

It was Buz who some years ago reminded me of the work of Warner Schaie, who is being honoured with a Lifetime Achievement Award. All I had remembered was that in studying ageing effects one had to distinguish between cohort effects and ageing effects, by some technique I needed to look up. Buz immediately understood that attempts to study the Flynn Effect ran up against the same problems as the study of ageing, and that repeated measures of age cohorts provided a better insight. That is, when comparing 60 year olds with 18 year olds you conflate cohort and ageing effects, but if you re-test both groups every 10 or 20 years you can distinguish between effects. Warner Schaie led the way.

In line with conference traditions, here is the Keynote, delivered by Yulia Kovas, who is hosting the conference with colleagues.

KEYNOTE ADDRESS
Behavioural Genetics for Education:
New Insights into the Origins of Academic Ability,
Motivation and Achievement
Yulia Kovas
Goldsmiths, University of London & Tomsk State University
Many  findings of importance for education have recently emerged from genetic research, suggesting that genetic effects are not static or deterministic, but change throughout life and in different educational and cultural contexts. For example, academic achievement – such as performance in reading, language and mathematics – has been found to be highly heritable throughout school education in the UK. On the contrary, heritability of general cognitive ability is only moderate in the early school years and increases gradually, reaching substantial levels in adulthood. It is possible that high heritability of reading and mathematics can be explained by the high homogeneity of educational environments. For example, the UK National Curriculum is highly uniform
and therefore may decrease the environmental contribution to the variance in these traits. On the contrary, general cognitive ability is not explicitly taught at schools, and therefore may be
under highly variable environmental influences across children, especially early in development.
Gene-environment correlations, whereby children experience, modify, and select their environments – partly because of their genetic propensities – may contribute to the observed increase
in heritability of IQ. Recent large-scale twins studies also provided insights into the origins of individual differences in such educationally-relevant characteristics as motivation, grit, academic anxiety, and choice of specific academic subjects. Incredible recent advances in molecular genetic research have led to identification of specific DNA polymorphisms responsible for ubiquitous genetic influence. Moreover, new methods allow us to make predictions about development directly from DNA, which opens up unprecedented opportunities for further research and educational practice.

More in a moment.

Some thoughts from China

 

You may remember that I posted up some research on dysgenic trends in China,.

http://drjamesthompson.blogspot.fr/2016/06/china-getting-duller-perhaps.html

Mingrui Wang, the lead author, has now added some further comments.

The paradox of democracy
In democratic societies, the government is elected by the people and it will respect their wishes. Sometimes, their wishes can be conflicting. For example, there can be a paradox between differential fertility desire and the development of society.
Rational individuals ought to hate eugenic policy and love dysgenic fertility.
There are two kinds of eugenic policies that try to alter the relative fertility rate of individuals with different breeding value (e.g., IQ) - positive and negative eugenics. Positive eugenics policies aim to increase the fertility of high IQ individuals. Negative eugenics policies aim to decrease the fertility of low-IQ individuals. These two kinds of policies are self-evidently unwelcomed by affected individuals because they aim to deviate their behaviour from their wishes. The reproductive behaviour of individuals who fall between these two extremes is unaffected by eugenic policies. They should hate eugenic policies too because if the proportion of high IQ individuals rises while the proportion of low IQ individuals falls, they and their offspring tend to become the new low IQ individuals. Eugenic policies, therefore, conflicts the interest of every individual in the society.
In the real society, low and high IQ individuals both have their wishes respected. As the proportion of low IQ individuals rises and high IQ individuals decreases, IQ of medium IQ individuals and their offspring rises quietly. Don't forget IQ is actually a sorting tool, setting population average=100, SD=15. More than the performance on a test, their relative rankings in wealth also rise in the society. Don't forget, people feel happy because they are better than others. You may enjoy far more modern gadgets, eating more kinds of food, than any ancient emperors, but not feeling happy as they did. When controlling for an individual's own income,
higher earnings of neighbours are associated with lower levels of self-reported happiness. Dysgenic fertility and immigration will, therefore, increase the happiness level of individuals in the medium class. Hence, dysgenic fertility ought to be favoured by people from each class of the society.
On the other hand, individuals also desire the benefits from a strong society (e.g., defence and welfare), which might not be possible if dysgenic fertility persists for a long time. Therefore, democracy might be a paradox because it respects conflicting wishes from the people.
Although China is considered by the west as an authoritarian nation, the rise of thoughts on individual rights might make eugenic policies also not feasible here. Breaking fertility regulations in China will face fines, which make it look like a
crime. Behaviour genetic research suggests all psychological traits show significant and substantial genetic influence, so there might have been a selection favouring genes that predispose individual to break such policy. The rise of regulation-breaking genes will make any eugenic policy not long-term sustainable, even in China.
You may think China have already implemented a eugenic policy. The fertility policy indeed contains some element of "good birth". But it is mainly about a good rearing of children and the elimination of genetic defects. It completely ignores the literature of behaviour genetics. In the 1980s, there are Chinese scholars who have noticed the possible "inverse selection" on the urban status and they were ignored. In 2007, Di Zhenwu, the dean of School of social and population college of Renmin University of China published
an article rejecting this claim by pointing out the increase in the proportion of the urban population and the large gains in the quality of the rural population. He did not consider the possibility that selective immigration wakened genetic quality of rural population because those who have left were those had been less able to move out. I expect critics continue to urge that the lower IQ of individuals with a higher fertility is completely due to environmental reasons. So at the end of the paper, I challenged them to refute by conducting molecular studies.
Perhaps the only solution is genetic engineering, a kind of within-family eugenics, if it is technologically possible. For the issue of dysgenics, I am planning to write a Chinese language review to raise awareness on it. I hope more research in related areas can be done.

The Economist is economical about intelligence

 

The Economist is not a reliable guide to human ability. It believes in homo-economicus: all-purpose, equipotential beings without inherent differences, any such adventitious peculiarities to be smoothed away by compensatory education and the amelioration of unfavourable circumstances.

Very occasionally, like a maiden aunt reluctantly acknowledging the existence of sexual arousal, they refer to genetic differences, but soon revert to their standard mantra: with more education, earlier education, and more flexible education those nasty gaps between one person and another, and one group and another, can be washed away. Perhaps so.

As part of a holiday ritual I buy The Economist to take to the beach and find out if it has improved. The issue of June 25th looked promising, in that it had a special report on artificial intelligence, in which they said that the intelligent response to the dislocation caused by this development would be “making education and training flexible enough to teach new skills quickly and efficiently”. Quite so. They should have added “but the intelligent will always learn more quickly and will generalise their learning more widely, and to greater advantage”. Learning speed is correlated with general ability. The US armed forces have all the data, and Linda Gottfredson has dug it up. The Wonderlic data also show that training a person in one simple task in one ability domain does not generalise to improved ability in simple tasks in other ability domains. A task is learned, but the individual is no brighter or faster at learning the next task.

They also champion social skills, which they say will be particularly required when robots strip out many humdrum jobs from the economy. However, social skills and character are largely personality characteristics which are heritable, and not easy to alter. (Heritability estimates for personality variable may be lessened by the poor reliability of self-assessed personality, so the use of better tests may show even higher heritability than the current 40% or so). Some social skills can be trained, and this is currently very popular, because it is cast as “emotional intelligence” and everyone likes being intelligent in some way. Moving in a mysterious way, for example.

Measures of emotional intelligence turn out to contribute little to job success and response to training. Hunter and Schmidt.

Being one standard deviation above the norm leads to 60% higher wages. These are OECD results, though they make absolutely no mention of intelligence.

The special report on artificial intelligence is worth reading. They point out that advances in technology usually create new jobs of different sorts, usually more complicated and demanding service jobs. Most people keep busy and are in work. The authors don’t mention that the current elite belief that mass immigration is required to provide low skilled workers does not sit well with the promises of artificial intelligence: governments seem to be hell-bent on bringing in people to do jobs which , if the advances of artificial intelligence are to be believed, shortly will not exist.

Although the report is interesting, one needs to fill in the empty spaces. It shows US employment by type of work (US Population Survey, Federal Reserve Bank of St Louis). The graph shows that the greatest increase since 1983 is in “non-routine cognitive” jobs, with routine cognitive and manual jobs stagnant, and even non-routine manual jobs increasing. They fail to point out that routine jobs are for those who need training on every step of a simple job, and that these people find departure from routine challenging, because those non-routine problems require higher ability. “Non-routine” jobs are where brighter people flourish because they do not need to be trained on each step of a task, but can grasp the general principles. This is increasingly the case at IQ 115 and above.

It is findings of this sort which make me question the predictions of Frey and Osborne (2013) as to which jobs are at risk of being replaced by artificial intelligence. They list many complicated non-routine jobs as being at risk: typists, technical writers, and accountants and auditors. Typists have already been reduced in number, but highly paid busy people still employ them, because on Ricardo’s principle of comparative advantage it is worth while for a highly skilled, highly paid individual to employ one so as to free up their own time. In this way digital secretaries can proliferate in Scottish islands while executives fret in central London: these assistants are not strictly necessary but very useful. Equally, global job clearance centres (oDesk and others) can provide people to spruce up websites, enter data, draw graphs and generally tidy up stuff so that higher paid workers can get on with their higher paid enterprises. Will auditors become redundant? Seems unlikely. More likely that they will extend the scope of the feedback they give their clients. We shall see.

By the way, self driving vehicles, all the rage at the moment, may turn out to be something of a waste of time, except perhaps in slow moving traffic jams. Incidentally, such jams might be better dealt with by road pricing systems: charge by the minute rather than the mile and road users will stagger their journeys or use satnavs and local knowledge to work round traffic jams.

The main point is that driving is too easy. Most people can do it. The better thing would be to automate motor maintenance and repair. Drivers are cheap, mechanics expensive.

Further into the magazine another story caught my eye. “A running start: Poor children fall behind early in life. Better pre-school education could help”. This notes with dismay that “By the time pupils begin primary school, there is a huge gap in achievement between rich and poor”. It further notes that the plus one standard deviation between 10th and 90th income percentiles in school achievement has barely diminished by age 18, equivalent to several extra years of secondary schooling. How to explain this? Perhaps brighter parents earn more and have brighter children, with some drift downwards because of regression to the mean. Perhaps duller parents earn less and have duller children, with some drift upwards because of regression to the mean. This obvious genetic hypothesis is not mentioned. Instead (brace yourself) poor parents don’t talk to their children, because of poverty. “By the age of 6 children of wealthy parents have spent as much as 1,300 more hours in enriching activities than those of poorer families.”

How to test this, avoiding the blindly obvious confounder that the bright and wealthy parents are bringing up their own genetically brighter children? How about something more powerful than necessarily part-time pre-school activities? How about full time adoption?

The article then goes into the Perry Pre-school project and a few selected Head Start programs. I sympathise. I could have written such an article 4 years ago, based on my favourite examples of early pre-school intervention, until I knew better.  The general drift of the findings on pre-school intervention is disappointing. Interventions do not have lasting large effects on intelligence, and the welcome general beneficial effects are not often found, apart from the frequently mentioned star projects, which turn out to be outliers. Andrew Sabisky found the paper and the link is below:

Although the trend shows little effect, the outliers need further investigation. Ramey, talking at the ISIR conference in San Antonio, said that they reason he got results with the Abecedarian project whilst others did not, is that he made his teachers understand that if they didn’t get results they would not have a job. They followed protocols carefully, was his argument. He is running replication studies, this time with a full genome on each child, so we should have better results say 25 years from now.

There is nothing malign in offering compensatory education to young children, just significant doubt that it is effective and can be scaled up across entire education systems to smooth away real individual differences.

The Economist has massive reach among influential people in the world’s economies. The magazine, popular as it is with readers wanting to understand the ways that economies work,  is resolutely behind the curve of contemporary research on human ability. One day The Economist may commission articles from people who know something about intelligence, education and genetics. For example, Ian Deary, Robert Plomin, Stuart Ritchie, and Tim Bates for a start. Until then, blogs like this one will be bringing the most recent findings to a small but highly select group: my dear readers. If your friends sometimes read The Economist, can you direct them to this post, in the hope that they can avoid the torrent of misunderstanding purveyed by the mainstream received wisdom? It would be a small mercy.

The Economist is confused about human beings, but if we are to accept their shaky presumptions about the power of pre-school education, then even journalists can be educated, if they can be caught young.

To Russia, with love and Powerpoint

 

Unusually, the next ISIR conference will be held in summer, in a week’s time, so this presents a challenge for intelligence researchers, used to winter weather in which it is appropriate to huddle in cellars looking at Powerpoint slides. Now the whole of St Petersburg will be shining golden in the sun, and what are the mere rotations of factors when compared with a stroll down the Nevsky Prospekt, perchance bumping in to the ghosts of Russian literature, and perhaps even a young Nabakov making his way to school.

However, the feast of modern day intelligentsia may win out in the end: M.A.McDaniel, Warner Schaie, Robert Plomin, David Lubinski, Linda Gottfredson, Doug Detterman and virtually everyone doing intelligence research will be there, so the architecture, canals, palaces, the Hermitage and other diversions may be set to one side by delegates intent on improving their already well-stocked minds.

So long as delegates can find their passports, and also get their Visas, which apparently is done through hotel bookings, they will all converge on the Window to the West for the 15th July opening session.

Much more about this soon.
