Eric Turkheimer (April 4, 2025). Is Tan et al. The End of Social Science Genomics? Eric Turkheimer - Gloomy Prospect Blog (via email) [Tan et al.: https://www.medrxiv.org/content/10.1101/2024.10.01.24314703v1?utm_source=substack&utm_medium=email ] [ "Now I get to the only part where I need to be a bit critical. I should be clear at the outset that there is nothing sneaky about the way the data were reported. All of the results are mentioned in the text, illustrated in the figures, and listed in the supplemental tables. All I had to do was copy them out. My issue, at bottom, is with the discussion section. The authors of this paper are not just quant genetic technicians. They are working scientists, many of them working behavioral scientists, many of them public enthusiasts for the utility of GWAS-based genomics for understanding complex human behavior. Many of them, not to personalize things, have found occasions to let me know that I am “too pessimistic” about the possibilities of applying PGI in the real world. So you would think that when all was said and done they might say something about the fact that unconfounded genetic effects turned out to be very small at the level of heritabilities, and zero at the level of PGI, but there is nothing. The actual results of the study are simply ignored. There is, as I have said elsewhere, an unrecognized effect size crisis in GWAS-based behavior genetics. The response of the field has been to ignore it instead of grappling with it. The Spit for Science project, which I wrote about last year, is a similar but different expression of the same problem. S4S wasn’t a big technical exercise like this one, it was a smaller (n=12,000) effort to apply genomics in a real-world setting on a college campus. But exactly like this report, S4S spent a decade reporting thoroughly null results, while studiously avoiding the implications of their own findings."] What happens when everything is unconfounded?

• At first we detect no more than a shadowy premonition of those sprawling, amorphous, yet insistent institutions of medicine that now absorb limitless resources and intrude into every dimension of our lives. Yet by 1850, mental hospitals were becoming, in parts of Europe and North America, the costliest of social programs. We might think of them as a trial run for the welfare state, working to relieve the suffering of the mentally ill and to lighten the terrible burden on their families and communities. As sites of medical treatment, they soon appeared to be failing. Yet it was scarcely possible to set free or even to hold back the intake of so many thousands of deranged, unruly, inconvenient, and (at times) dangerous persons. The eugenics movement, which has so often been characterized as an (illegitimate) outgrowth of Darwinian biology, is better understood as a reaction to the failure of asylum care to check the hyper-Malthusian increase of the institutionalized insane. Alienists (as doctors for the mad were called) set out on the basis of statistics to ascertain the principles by which insanity was reproduced. About 1880, with the spread of mandatory schooling, a parallel crisis of 'feeblemindedness'` began raising alarms. Institutions founded to treat these conditions supplied not only the incentive for a science of human heredity, but also its experts and its abundant reserves of data

• Nor have efforts to determine the proportional contribution of hereditary and environmental factors to observed individual differences in given traits met with any greater success. Apart from difficulties in controlling conditions, such investigations have usually been based upon the implicit assumption that hereditary and environmental factors combine in an additive fashion. Both geneticists and psychologists have repeatedly demonstrated, however, that a more tenable hypothesis is that of interaction (15, 22, 28, 40). [HALDANE, J. B. S. Heredity and politics.

• Conclusions and Outlook
  The results reviewed here suggest a provocative reconceptualization of the relationship between social opportunity and the magnitude of heritable variation in cognition. We began this article with a quote that illustrates the common view that heritability estimates provide an “upper bound” on the effects of social intervention—if cognition is very heritable, then the environment cannot matter as much. In fact, research on how the heritability of cognition differs across development and across context suggests that genetic influences on cognition are maximized by environmental opportunity. The highest heritability estimates are obtained for older children and adolescents from economically advantaged homes—that is, among children who have the autonomy to select environmental experiences consistent with their own interests and who have an array of high-quality experiences to choose from. As social, educational, and economic opportunities increase in a society, genetic differences will account for increasing variation in cognition—and perhaps ultimately in educational and economic attainment.

• So irrespective of study design, twins or census, we find a high heritability for educational achievement in the Netherlands. The high heritability might be explained by the homogeneity in educational opportunities: most schools are tied to a standard curriculum and funded by the government (Sturm et al., 1998;- de Zeeuw et al., 2015), which might restrict the variation in school environments, leading to smaller individual differences between (see e.g.,- Heath et al., 1985;- Kovas et al., 2013;- Shakeshaft et al., 2013;- Colodro-Conde et al., 2015- for a similar argument).

James Flynn (2016). Does your Family Make You Smarter? Nature, Nurture, and Human Autonomy. info.

The first chapter 'Twins and autonomy' is some kind of summary. James Flynn will conclude the following (quote)

Chapter 2 starts serious business. The important concept here seems to be the cognitive quality of the family environment. No, Flynn does not explain what it is, at least not on p. 12 (but see appendix p. 180). Neither does he point out that there is a strenuous relation between that concept and the family genes. Having said that, it seems impossible that the child's genes and the cognitive quality of the family environment are independent variables, not being correlated. This is one of the stumble blocks making it difficult to understand what exactly Flynn is trying to do in this first part of his new book.

Ch 2 p. 13, introduces a serious confusion of 'true' and 'measured' vocabulary. What exactly does Flynn mean where he writes 'students whose vocabulary puts them at +2 SD above average'? Is it 'true' vocabuary, or is it 'level of performace' (on a vocab test) as mentioned in the preceding sentence? Is it possible for a psychometrician to conclude from some top score on a vocab test that a particular student is 98th percentile in true vocabulary? In his tables Flynn strongly suggests they are dealing with observed scores. Yet it is impossible for a +2 SD score to correspond to a +2 SD 'true' vocabulary. Flynn is talking of true vocabularies and observed vocabularies (at +1 SD etcetera) at the same time.

Ch 2, p. 18, turns the reasoning around, without mentioning as much; '.. those who would get an SAT-R score of 544, if they came from from a home typical of of those who score at that level.

Appendix 1 p. 181 at the top: 'eliminating 30 percent from the bottom of a normal curve lifts the SD of the remainder by 0.4967 SD.' This is utterly confusing; the first 'SD' should be 'median' to make it reasonable. And again in the second alinea. Proof: how Flynn talks in the second half of this page. Back to. the top passage 1): I do not understand the reasoning here at all. Yet it is crucial to everything else that follows.

For the time being, I give up on the first part of Flynn's Does your family make you smarter. I do not understand what he is doing here, it is a big thought experiment. The second part of the book is very interesting, does not however touch on the title theme.

High heritability of IQ (tested in adult age), what is its significance, if any? For starters, the question itself is a reification of the abstraction. A test is an instrument, not a societal goal. These issues confused my reading of Flynn's 'Does your family make you smarter'? https://twitter.com/benwilbrink/status/947094569509892096 Richard Nisbett does not confuse me. In his 2009 'Intelligence and how to get it' ‪http://books.wwnorton.com/books/Intelligence-and-How-to-Get-It/- …‬ p. 38: “The degree of heritability of IQ places constraint on the degree of modifiability that is possible. All geneticists accept this principle, but hereditarians often acknowledge the principle and then go on to write as if heritability does in fact place limits on modifiability.” An example in the last category: Asbury & Plomin 2014 'G is for genes'

Flynn does not touch on expertise (Anders Ericsson) and how that relates to common smartness. Yet it seems to be the case that the phenomena of expertness show the concept of rather fixed intelligence to be at fault, in somewhat the same way the existence of 'Flynn-effects' does.

• Some of the subtests (Vocabulary, Information, Comprehension) that show children gaining the least from one generation to another are also the subtests that show the most persistent family effects within a generation. These are the very subtests most important for academic achievement and, therefore, their persistent family effects do most to handicap (or benefit) 17-year-olds.

• As a preliminary, before the age at which the matching of an individual's genes with current environment begins (perhaps age 3 or 4), I posit that family determines virtually all of performance variance (this will be revisited in Chapter 6).

• Dickens posited that genes and environment simply become more highly correlated as we age, which implied that their influence was additive and not a matter of one draining potency away from the other - the potency of the environment was masked by the combination, which thanks to the twin studies was ascribed to genes alone.

• Arithmetic: tiny gains for both school children and adults in terms of arithmetic reasoning. We clearly do not know how to teach this skill no matter how long we keep people in formal education. An obvious consequence is the fact that America has to import half of the engineers it needs.

• Galton's (1869) classic directly addressed the question of whether genius is born or made, coming down strongly in favor of a genetic basis (Simonton, 2003). ( . . . ) Indeed, shortly after Galton (1869) published his argument for nature, Candolle (1873) offered the counterargument, with special focus on familial and educational experiences.

• If Galton's (1869) historiometric study is the first to examine the early origins of genius, Quetelet's (1835/1968) represents the first to investigate the career trajectory once the genius enters adulthood.

  90

• Given the frequent association of genius with superlative intelligence, this individual difference variable seems an obvious place to start. Although Galton (1869) talked about differential 'natural anility' in his sample of geniuses, he never measured that construct directly.

The paradox of intelligence: Heritability and malleability coexist in hidden gene-environment interplay.- Pages 26-47.- Sauce, Bruno; Matzel, Louis D. (2018). - http://dx.doi.org/10.1037/bul0000131- Psychological Bulletin paywalled see also: https://neurosciencenews.com/inherited-iq-kids-8356/

• Intelligence can have an extremely high heritability, but also be malleable; a paradox that has been the source of continuous controversy. Here we attempt to clarify the issue, and advance a frequently overlooked solution to the paradox: Intelligence is a trait with unusual properties that create a large reservoir of hidden gene-environment (GE) networks, allowing for the contribution of high genetic and environmental influences on individual differences in IQ. GE interplay is difficult to specify with current methods, and is underestimated in standard metrics of heritability (thus inflating estimates of “genetic” effects). We describe empirical evidence for GE interplay in intelligence, with malleability existing on top of heritability. The evidence covers cognitive gains consequent to adoption/immigration, changes in IQ's heritability across life span and socioeconomic status, gains in IQ over time consequent to societal development (the Flynn effect), the slowdown of age-related cognitive decline, and the gains in intelligence from early education. The GE solution has novel implications for enduring problems, including our inability to identify intelligence-related genes (also known as IQ's “missing heritability”), and the loss of initial benefits from early intervention programs (such as “Head Start”). The GE solution can be a powerful guide to future research, and may also aid policies to overcome barriers to the development of intelligence, particularly in impoverished and underprivileged populations.

Barbara Beatty (1998). From Laws of Learning to a Science of Values Efficiency and Morality in Thorndike's Educational Psychology. October 1998 American Psychologist Vol. 53, No. 10, I145-1152 pdf [Edward L. Thorndike]

• Thorndike was vehemently opposed to Hall's notion that the school curriculum should follow nature and recapitulate the stages of human cultural development. Not only was Hall's developmentalism intellectually uninteresting and methodologically inexact, Thorndike thought it was immoral and potentially dangerous. Schooling should improve upon nature. Not everything in nature was good; there were base instincts as well as good ones. Educators should use the impulses of nature only if they "further the aims of education. . . . when they work toward moral ideals" (Thorndike, 1901b, p. 136). "What development is can never teach what it ought to be," Thorndike stated, condemning Hall for committing the naturalistic fallacy. "No word perhaps is a poorer synonym for 'the good' than 'the natural' (Thorndike, 1901b, p. 136-7).

  1146

  Although Thorndike rejected Hall's developmentalism and genetic psychology, he did not reject the genetic component of individual differences. For Hall, genetic psychology meant the history of the development of the human race; for Thorndike, genetic psychology meant biologically inherited characteristics in individuals.

  1147

  Although Thorndike did not think there were significant sex differences in intellectual ability, he thought there was a strong genetic component to individual variation, including variation in morality. He published studies on heredity and on twins in 1903 and 1905, quoted Galton frequently, and thought intellect had such a high, fixed genetic component that, to be efficient, schools should group children into different classes and programs by ability. Thorndike's hard-nosed position on genetic limitations on human potential and the inefficiency of providing equal education to all children was to become one of the main, longstanding criticisms of his work (see Jonqich, 1962, 21-22). "It is wasteful," he wrote in the 1903 version of his Educational Psychology, "to attempt to create and folly to pretend to create capacities and interests which are assumed or denied to an individual before he is born" (p. 44). Thorndike also thought there was a genetic component to morality. But in contrast to his views on intelligence, at this early stage in his career he felt that environmental influences had a greater impact on character than on intellect, a position he would later modify. "The important moral traits seem to be matters of the direction of capacities and the creation of desires and aversions by environment to a much greater extent than are the important qualities of intellect and efficiency" (Thorndike, 1903, p. 45).

  1147

  Unabashedly hereditarian and meritocratic, Thorndike thought more traditional, moral, political, and humanitarian views did not give enough weight to individual differences and was determined to find a scientific way to do so. "Ethics, politics and philanthropy have been guilty of neglecting individual differences, partly because doing so simplifies all problems, and partly because of the retention of theological and sentimental prejudices in favor of the similarity and equality of man" (Thorndike, 1940, p. 369).

  1150

  Like many other progressives, Thorndike supported eugenics and now proposed giving political power to the genetically more able (see Curti, 1980; Hailer, 1984; Kevles, 1986). Thorndike had lectured on eugenics as early as 1913, but had stopped short of wholeheartedly recommending it (Thorndike, 1913). After more than 900 pages, the conclusion of Human Nature and the Social Order was an alarmingly simplistic list of 20 suggestions. Along with "increasing capital goods" and "the elimination of wars between and within nations," Thorndike recommended "better genes," "guidance by science," and a "national council of the able, good, and impartial endowed so as to be utterly their own masters" (Thorndike, 1940, pp. 957-961). Thorndike said he supported absolute meritocracy because quality "was better than equality" (Thorndike, 1940, p. 962). Despite the unreasonableness of some of these conclusions, his final recommendation was to have "Reasonable expectations" (Thorndike, 1940, p. 963).

  1151

  When the state of the job market in psychology led Thorndike to shift his attention from animals to education, he maintained the nineteenth-century linkage between intellect and character. In The Human Nature Club, Thorndike questioned traditional religious views but allowed for the possibility of Jamesian spirituality. In Notes on Child Study he rejected Hall's developmentalism as uninteresting, inexact, and immoral and advocated differential rather than genetic psychology. In the first version of Educational Psychology Thorndike maintained that the moral aims of education should be determined by ideals, not facts, and that morality was more influenced by environment than intellect was. In The Principles of Teaching he described morality as a product of learning acquired through numerous specific connections. In the second version of Educational Psychology he stated a genetic view of the origins of ideals. At the end of his career, in Human Nature and the Social Order, he proposed a moral measurement system and advocated selective breeding to enhance individual and social goodness. Incrementally, like the connections in his theory of learning, Thorndike' s explanations of morality became more efficiency-oriented, biologically-deterministic, and positivistic.

• Interventions of the right kind, including in schools, can make people smarter. And certainly schools can be made much better than they are now.

• Environmental factors operating within groups need not be identical to those operating between groups. The 'factor X' argument from Lewontin.

  212

• Nisbett does not give footnotes or references for his Appendix B 'The case for a purely environmental basis for black/white differences in IQ!
• Dickens and Flynn (2001) proposed a formal model that solved the problem. They showed that two groups couls be separated by an environmental factor of great potency that did not affect each member of of the groups equally. They illustrated the point with the effects that TV had on the escalation of basketball-playing ability. [such as passing and shooting with both right and left hands]. ( . . . ) With their identical genes and identical height and quickness, identical twins were likely to have common basketball histories - and sice genes and powerful environmental factors went together, genes would get the credit for the whole package. [old vs new techniques]

  212-3

  It is now easy to imagine a variety of environmental factors that are potent and that separate black and white Americans. ( . . . ) And none of these things has to behave like the implausible factor X.

  213

  In sum, the indirect arguments for genetic determination of the black/white gap in IQ are inherently weak and readily refuted. The most direct evidence - the only evidence that really counts - concerns the European heritage within the black population. With a single exception - which happens to be the only study reported on at any length by either Herrnstein and Murray (1994) or Rushton and Jensen (2005) - the data show that more European genes are not advantageous for blacks. The last thirty years have seen a reduction in the gap in IQ by about a third and a reduction in the academic achievement gap by about the same amount. The evidence favors a completely environmental explanation of the remaining difference between blacks and whites.

• • Sandra Scarr: Behavior-Genetic and Socialization theories of intelligence: Truce and reconciliation pp 3-41 summary and pdf "Competing theories about determinants of intellectual differences offer a challenging opportunity to test theoretically required predictions with available observations. Predictions about crucial research results are generated by Socialization Theory and by Behavior-Genetic Theory, and those predictions are quite different. The critical observations to test the adequacy of predictions from these competing theories have been made. Yet, there has been little, direct theoretical confrontation. That the theories have not been tested with existing data in a systematic fashion is either a sign of mutual ignorance or an aversion to being challenged.
    This chapter presents Socialization and Behavior-Genetic theories of intelligence and evaluates the adequacy of the theories' predictions to account for existing observations."
  • A. R. Jensen: The puzzle of nongenetic variance, 42-88 summary "Within the past decade, empirical findings in behavior genetics have importantly changed how researchers in this field think heredity and environment affect individual differences in mental ability. These insights are hardly new. Some are even found in the writings of Sir Francis Galton (1822-1911), the father of behavior genetics. But the recognition, formalization, and empirical support given to them by behavior geneticists in recent years can be considered significant advances. The most surprising findings, only conjectured by Galton, concern the role of environment in the development of mental ability. The present picture is quite different from the beliefs generally held only a decade ago.
    Genotype-environment covariance
    One such idea is that the perceptible environment is like a cafeteria. People make different selections according to their genetic makeup, or genotype. The environment is not a “given” but is largely the person's own creation. This becomes increasingly true as persons develop from infancy to maturity.
    Behavioral differences between persons that result from their self-selected and self-fashioned environments are the phenotypic expression of genotype-environment covariance. It accounts for more of the total variance (i.e., individual differences) in abilities and achievements than was formerly thought. Genotype-environment (GE) covariance is neither a strictly genetic nor a strictly environmental component of phenotypic variance but reflects the genetically driven differential selection of experiences from the available environment. It also includes the effects of differential treatment by parents, teachers, and peers, because their responses are largely evoked by the person's distinctive genotypic characteristics."

Both the idea of a general factor of cognitive ability, Spearman's- g, and the idea that genetic factors might be an important source of variance in cognitive ability have been continuously debated since they were first systematically expounded by Galton (1869, 1876). Reviews of Galton's books published in the- London Times- at the time of their appearance could, if slight changes were made, be published today. The debate on the nature of mental abilities and the influence of heredity on such abilities (as well as most other psychological traits) initiated by Galton continues unabated.
  • Douglas Wahlsten, Gilbert Gottlieb: The invalid separation of effects of nature and nurture: Lessons from animal experimentation pp 163-192 summary "Several decades of research involving nonhuman animals have led many scientists to a developmental systems explanation of the origins of brain and behavior. Developmentalists recognize the importance of genetic variation for individual differences in behavior but also appreciate that the complex sequence of bidirectional, interacting causes makes it almost impossible to assign a definite role to the genotype unless a major gene can be identified. The prevalent model in human behavior genetics, on the other hand, presumes that heredity and environment are additive, separately acting causes whose contributions to any characteristic can be neatly separated statistically. This presumption is biologically unrealistic in view of all that is known today about the control of gene action and the interdependence of genetic and environmental effects.
    In this essay, we focus on lessons learned from animal experimentation that have special relevance for understanding individual differences among humans. We argue that a general theory of proximate causes of behavioral diversity is broadly applicable to all mammals and, in most respects, all vertebrates, but the theory is a developmental one, not one based on the invalid dualism of nature-nurture inherent in quantitative behavior genetics."

Torff: A third perspective: the symbol systems approach. 243-268 summary "In the behavioral sciences, no issue has been more passionately joined than the relative contribution to human behavior of hereditary (genetic) or environmental (cultural) approaches. In one sense, the debate dates back at least to the beginnings of the modern philosophical era: Contemporary hereditarians (hereafter Hs) can date back their pedigree to Descartes and Leibnitz, while contemporary environmentalists (hereafter Es) can trace their intellectual heritage to the British empiricists, such as Locke and Hume."

  • Stephen J. Ceci, Tina Rosenblum, Eddy de Bruyn, Donald Y. Lee: A bio-ecological model of intellectual development: Moving beyond h2 pp 303-322 summary "In her 1958 Presidential Address to APA, Anne Anastasi urged psychologists to move beyond the question of studying “how much” variance was accounted for by genetics and environment and instead to address the question of “how” genotypes were translated into phenotypes. Despite the passage of nearly 40 years, Anastasi's challenge has not been taken up. Today, we know much more than we once did about the role of genetics in intelligence, the distribution of alleles at neurologically relevant sites, and the molecular chemistry of brain functioning, but we still know as little as ever about the mechanisms through which genetics get translated into phenotypic intellectual expression.
    In this chapter, we endeavor to say something about the process that translates genes into phenotypes and, in so doing, say something about the environmentally loaded nature of heritability and the genetically loaded nature of the environment. While acknowledging the important role that genetics plays in intellectual development, we shall nevertheless take issue with the traditional “percent of variance accounted for” model of behavior genetics. In its place, we will suggest that traditional heritability measures do not inform us about the manner in which genes exert their influence, nor even about the organism's genetic potential. Rather, they tell us what proportion of individual differences in already actualized genetic potential has been brought to fruition by the prevailing environment. Left unknown, and unknowable from the traditional model, is (1) the amount of the organism's unactualized genetic potential, and (2) the absolute level of intellectual competence around which individual variation occurs."

Lemons: An interactionist perspective on the genesis of intelligence pp 323-340 summary 'Such is the case in the continuing pursuit of understanding relevant to issues concerning the relationships between intelligence, heredity, and environments. Our conceptions of each of these constructs are influenced by differential perspectives, which are often influenced by differences in the respective social position held by the investigator. One need only look at the long history of political contamination of this debate to see how much our efforts at explaining these relationships have been shaped by concern for differences in status attributable to class, race, and sex. In approaching this set of issues, we make no claims to objectivity. The authors of this chapter are conceptually biased in favor of epigenetic and interactionist conceptions of the origin and nature of human behavioral development. We are politically biased in favor of egalitarian and humanistic values as guides to inform social organization.'

• No prediction can be made from a knowledge of the degree of genetic determination about the efficacy of curative or preventive treatments. All that could be said in such a case is that one will have to look outside the range of normal environments experienced by the untreated population.

• For Augustine, as for Plato, sensation is not the source of all knowledge because certain forms of ideals are innately present in memory, and the role of sensation is to 'remind' one of what is already known. For Augustine, and indeed for many later theologians, the epitome of such innate knowledge was that of God himself, but more secular knowledge, for example, that concerning numbers and the laws of mathematics, was also present in this way. [Augustine, Confessions see note 32 for exact place]

Contents:

1. Intelligence as Potentiality and Actuality pp 1-14 By Phillip L. Ackerman https://doi.org/10.1017/9781316817049.002 This is a key publication connecting IQ and expertise of adults and adolescents. Yes! It is pretty ridiculous to test adults on IQ without considering their expertise in law, music, carpentry, whatever. Ackerman does not discuss its implications for claims of high heritabilities of IQ for adult, however. .
   Ever since Binet and Simon published the rst modern scales to measure child intelligence, the fundamental purpose of intelligence assessment has been for prediction ( .. ) Once one understands this fundamental issue in the study of intelligence, several key concepts must be considered, as follows:

   • First, intelligence is, more or less, contextually (and culturally) bounded. ( .. )
   • Second, intelligence is a 'relative' or normative construct. ( .. )
   • Third, intelligence is dynamic. ( .. )
   • Fourth ( .. ) one can make a critical distinction between intellience potentiality and intelligence actuality.
   For a conceptual discussion of investment and intellectual development, see Cattell (1971)
   understanding of adult intelligence is woefully incomplete. Assessments that give credit to adults for the wide variety of knowledge and skills that they possess have yet to be developed. A high proportion of an adult's day-to-day intellectual life is simply unaccounted for by modern IQ assessments.
2. Hereditary Ability: g Is Driven by Experience-Producing Drives pp 15-29 By Thomas J. Bouchard https://doi.org/10.1017/9781316817049.003. Criticisms of Gould's Mismeasure of man. My problem with this chapter: it sums up some literature (useful, of course), it is weak in explaining issues and relations. The key message of Bouchard seems to be: "“the genome impresses itself on the psyche largely by influencing the character, selection, and impact of experience during development” (Bouchard et al., 1990a. p. 228)." Dynamic interaction. I will have to return to the chapter text on that interaction theme.
   I have always thought it was amazing that while psychologists and others heavily emphasize the role of family environment, thus the emphasis on socioeconomic status (SES), in the shaping of intelligence in children, they conducted almost no studies of unrelated individuals reared together (URT). The URT design is the most powerful one to assess this source of in uence. As Figure 2.1 shows, this design suggests a value near zero in adulthood for shared environment (see the asterisks in Figure 2.1), a value below that suggested by twin designs, namely, about 10%. My view is that psychologists have been plagued by confirmation bias and highly resistant to strong inference and refutation of their theories (Bouchard, 2009). The influence of genes on IQ and SES was laid out for us a great many years ago by a brilliant and highly underappreciated psychologist, namely Barbara Burks (Burks, 1938; King, Montanez-Raminez, & Wertheimer, 1996). [Bouchard, T. J., Jr. (2009). Strong inference: A strategy for advancing psychological science. In K. McCartney & R.

   Galton, in his book Hereditary Genius (1869/1914), formulated the idea that individuals differ from one another in mental ability and noted that the range of differences was quite wide, had consequences for everyday life, and, like all the features of the organic world, was influenced by inheritance or what today we call genetics.
   (note 1) The book was originally published in 1869. In the 1892 edition Galton admit- ted that the title was misleading, that it had little to do with genius, and that it should have been titled Hereditary Ability (Galton, 1892/1962, p. 26). As Darwin noted in the quote that follows, the idea of “intellect,” a xed characteristic or a trait in which individuals did not di er, has a very long history.

   In this chapter we focus on findings from our research on sex differences in academic achievement and what they say about the role of culture in shaping mathematical and spatial cognition. Our research focuses on the policy and educational implications of spatial and mathematical ability that are correlated with psychometric data (e.g., SAT, GRE, NAEP) and raises questions about the nature and development of these differences and what role policy has in ameliorating them.
4. The Nature of the General Factor of Intelligence pp 49-63 Andrew R. A. Conway, Kristof Kovacs https://doi.org/10.1017/9781316817049.005
   In the current chapter, we present an overview of our program of research on the relationship between working memory, executive attention, and intelligence. This line of work has culminated in a new theory of the positive manifold of intelligence and a corresponding new model of the general factor, g. We refer to this new framework as process overlap theory (POT) (Kovacs & Conway, 2016b).

   As recently as 10 years ago, a steel chain of ideas dominated the minds of those who studied and measured intelligence. Much of my own contribu- tion has been to break its links and therefore I must describe them in some detail. Arthur Jensen was its best advocate. The enemies of truth tried to silence Jensen. Science progresses not by labeling some ideas as too wicked to be true, but by debating their truth.

   
   The Steel Chain of Ideas

   Jensen believed that intelligence is something that transcends culture, social history, and even species; a name for certain traits of a properly developed brain that allow us to solve the wide variety of cognitive prob- lems presented in everyday life. He based his beliefs on four pillars: factor analysis, kinship studies, the dominance of g (the general intelligence fac- tor), and the method of correlated vectors.

9. g Theory pp 130-151 Linda S. Gottfredson sci-hub.tw/10.1017/9781316817049.010 #key
   Where psychologists saw individual differences, sociologists saw social inequality. Where psychologists suspected genetic influences on cognitive competence, influential figures in sociology alleged an elite perpetuating itself under the guise of intellectual merit. Career-development psychologists asked how young people choose among different occupations; status-attainment researchers asked what bars the less privileged from entering the most desirable ones. Both theories of occupational attainment pointed to factors the other ignored. One classified occupations horizontally, by field of work; the other ordered them vertically, by prestige. One looked at the nature of work performed and interests rewarded in different occupations; the other only at the socioeconomic benefits flowing to workers in them. Both approaches had venerable histories and vast bodies of evidence, yet contradicted the other's most fundamental assumptions and conclusions.

• The authors have at no time conceived their problem to be to discover whether heredity or environment determines the development of the individual, nor even to derive a ratio to express, in any universal or final sense, the relative potency of the two sets of factors. The first statement of the problem is meaningless since development is always a function of of both genetic constitution and of environmental conditions. The second is indeterminate since such a ration depends upon the type of trait and the amount of variation which exists in both the genetic and the environmental factors which are compared.

• Educability is defined here as the ability to learn the traditional scholastic subjects, especially the three Rs, under ordinary conditions of classroom instruction. Thus it is apparent that educability in this sense is a relative concept. At present it is measured by tests of scholastic achievement. Educability is dependent upon intelligence, which is a theoretical construct to account for the consolidation of learning into organizational structures which permit its retrieval, broad generalization, and transfer to the soltion of new problems and to the facilitation of new learning. A theoretical distinction should be made between learning per se and the consolidation of learning into cognitive structures that permit retrieval and transfer. Thus short-term measures of school learning are less highly corelated with intelligence than cumulative long-term measures. The physiologcal structures underlying intelligence grow from birth to maturity in their capacity to consolidate learning into the kinds of cognitive structures that characterize intelligence. Whatever is learned but not consolidated in this manner is either forgotten or remains a relatively specific response to a specific set of stimlus conditions; (..). The really functional, usable part of traditional school learning is that which gets consolidated into these cognitive structures, and the extent to which this takes place depends upon the person's intelligence.

Is that true (what the title suggests)? I doubt it, therefore I'll have to study the book. Alfred Binet and Edward Thorndike are glaringly absent in the book. Francis Galton and James Flynn only mentioned in passing. The taboo Pinker is attacking is one of the later second half of the twentieth century, the dominant opinion in the first half (e.g. Edward Thorndike) being just the reverse.

• "This book is for people who wonder where the taboo against human nature came from and who are willing to explore whether the challenges to the taboo are truly dangerous or just unfamiliar. (..) And it is for those who recognize that the sciences of mind, brain, genes, and evolution are permanently changing our view of ourselves and wonder whether the values we hold will wither, survive, or (as I will argue) be enhanced."

• I suppose that for example individuals with Down syndrome will have been excluded from heritability analyses. I simply do not know. Exclusion of those cases introduces a serious problem, I think: how to decide who is in, who is not? I'll take a peek at Loehlin & Nichols 1976.
• pp 5-12. 1507 presumed twin pairs were sampled from 600 000 high school juniors administered the National Merit Scholarship test (that population is above average in ability and achievement, p. 6). In 1188 cases both twins returned questionnaires. They were sent testing materials
• for 850 sets completed testing materials were returned. A specific problem is that only twins both at school and both sitting the Merit test could be included in the sample. The authors signal the problem, no further mention of its significance in this research.
• From the conclusions (p.94) “Our data have thus not yielded any finaland conclusive answer to the heredity-environment question for personality, abilities, and interests. The data are generally consistent with a substantial influence of the genes in accounting for individual
• differences in these domains, but they imply a substantial influence of the environment as well—indeed, they do not altogether exclude a completely environmentalist position.The data do, it seems to us, have something important to say concerning this environment. And the upshot

Key publication on environmental dynamics, a rather extreme position though.

• The more general principle is that people are not randomly assorted into their environments. Social science research finds ubiquitous correlations between people and the environments in which they are found. The typical, usually unspoken, assumption is that some people are just unlucky and wake up one day to find themselves poor and ill-educated, whereas others are just lucky to have had opportunities for higher education and well-paying jobs. The unspoken implication of most "environmentally" motivated research is that merely providing have-nots with the same opportunities as the haves will equalize their outcomes. I will show that this assumption leads to false predictions about interventions to improve the lot of the have-nots, because people are not randomly thrust into their environments; rather, to a large extent, they make their own environments by expressions of genetic variability. This is not to say that morally or ethically people deserve their fates—only that their personal characteristics are correlated with them.

  205

  Thus, although some developmentalists have suggested that children may affect the ways their parents treat them, as well as vice versa (Bell, 1968; Chess & Thomas, 1984; Chess, Thomas, & Birch, 1968; Hunt, 1961; Thomas & Chess, 1980), the theory that children actually construct their own environments from available resources challenges the basic tenets of mainstream developmental psychology.
  Second, it is commonly observed that children in the same family resemble each other to some extent in intelligence, talents, personality, and interests. The standard interpretation of these sibling correlations is that they are caused by rearing provided by the same parents (Baumrind, 1993; Wachs & Gruen, 1982). Two mistaken inferences from sibling correlations are made: that siblings are very similar in the first place and that parents' rearing practices cause siblings' similarity.( .. )
  The child's role in the kind of parenting she or he evokes and reinforces has been underestimated (Scarr & McCartney, 1983). Genetic differences in how children react to and understand their environments has been neglected in developmental research. In addition, the fact that older children and adolescents select activities and people with whom to spend their time has enormous implications for understanding genetic and environmental effects. Third, the importance of nonshared family environments has not been understood.

• In contradistinction to the discreteness of genotypic classes demanded by Mendelian analysis lies the quasi-continuous nature of the phenotypic differences that are the stuff of evolutionary change. The evolution of species consists in the gradual accumulation of very small changes in physiology, morphogenesis, and behavior. Closely related species may differ on the average in their temperature tolerance or preference, in their size and shape, but it is often impossible to distinguish an individual of one species from another on one or a combination of these characters because of the broad phenotypic overlap between the groups. Even when no closely related species overlaps it, any species will show a range of variation for most of its phenotypic characteristics, variation which has both a genetic and an environmental component. Indeed, for most of the characters whose change the evolutionist wishes to explain, the variation between genetically identical individuals is likely to be of the same or greater magnitude than the variation introduced by a single allelic substitution at one of the loci affecting the character. Even if the heritability of IQ in Caucasians is 80 percent, as is estimated by some studies (Erlenmeyer-Kimling and Jarvik, 1963), the effect of a single gene substitution on IQ is small (except for drastic abnormalities giving rise to mental deficients) as compared with environmental variations. If this were not the case, the Mendelian inheritance of IQ would have been worked out long ago. Evolutionarily significant genetic variation is then, almost by definition, variation that is manifest in subtle differences between individuals, often so subtle as to be completely overwhelmed by effects of other genes or of the environment.
  ( .. )
  When we turn from fecundity to viability, the situation is even worse. Can we distinguish an individual fly whose genotypic probability of survival from egg to newly hatched adult is 95 percent from one whose probability is only, say, 45 percent'? Here is a drastic genetic difference indeed. But an individual either does or does not survive to a given age. Among adults all have survived and among eggs nothing can be predicted. The probability of survival is an ensemble property, not an individual one, so that enumeration of individuals by their phenotype is, in this respect, impossible by definition. Survival and reproduction are the two components of fitness, and genotypic differences with respect to these characters evolved directly under the influence of natural selection. Yet it is impossible to recognize and enumerate the different genotypes in a population with respect to those most basic of all characters.

  We see here the fundamental contradiction inherent in the study of the genetics of evolution. On the one hand the Mendelian genetic system dictates the frequencies of genotypes as the appropriate genetic description of a population. The enumeration of these genotypes requires that the effect of an allelic substitution be so large as to make possible the unambiguous assignment of individuals to genotypes. On the other hand, the substance of evolutionary change at the phenotypic level is precisely in those characters for which individual gene substitutions make only slight differences as compared with variation produced by the genetic background and the environment. What we can measure is by definition uninteresting and what we are interested in is by definition unmeasurable. This paradox in one form or another has plagued population genetics since Chetverikov proposed in 1926 that the measurement of hidden genetic variation and its mechanism of maintenance were the central problems of evolutionary genetics. The paradox is not yet resolved, but recent advances in molecular biology and in population genetic theory, which are the substance of this book, offer some hope of a resolution.

Correlation is a concept that is eminently useful yet entails loads of misunderstandings, especially so in issues of heritability. Therefore it might be important to be clear about the roots of the concept.

  Selective schools make no difference to GCSE results, study says. Analysis undercuts argument that grammar schools are needed for the brightest pupils to reach their full academic potential. Hannah Devlin Science correspondent @hannahdev Fri 23 Mar 2018 06.00 GMT page

  ---

  • The findings are published in the journal Science of Learning
    The study, based on 4,000 pupils who identified as white British and attended schools across the UK, assessed the pupils' genetic data, their families' socioeconomic status, their ability (measured by an IQ-style test), prior achievement (11+ or Sats results) and GCSE results.

    
    The study is also the first to show up subtle genetic differences between children who attend selective schools and those who do not. However, the genetic scoring system used to classify children in the study is viewed as controversial, and scientists are divided on the extent to which it is a true index for intelligence or academic potential. ( .. )
    The influence of genetics on achievement, Plomin suggested, is the “elephant in the classroom”, adding that in the future, genetic testing of children to predict their academic potential “will probably happen”. However, others questioned whether such a step would be useful or desirable.

Steven Pinker on New Advances in Behavioral Genetics (2016). The findings of behavioral genetics have turned out to be substantial and robust, and new studies are linking genes with behavioral traits like IQ blog

• Indeed,- the heritability of intelligence- has recently been corroborated by a new method which complements the classic studies of twins and adoptees and which solves an outstanding puzzle: Where are the genes? Most of the “Gene for X” claims of the 1990s turned out to be false positives that resulted from snooping around genomes in paltry samples. The discrepancy between the robust results from classic family research and the failures of the gene-hunters is called the Mystery of the Missing Heritability.-

• The pattern of results suggests that inequality and social policies can have profound effects on the heritability of educational attainment and achievement in a population (Gene-Gini interplay). For example, heritability is generally higher at greater equality levels, suggesting that inequality stifles the expression of educationally relevant genetic propensities. The review concludes with a discussion of the mechanisms of Gene-Gini interplay and what the findings mean for efforts to optimize education for all people.

• General cognitive function is a prominent and relatively stable human trait that is associated with many important life outcomes. We combine cognitive and genetic data from the CHARGE and COGENT consortia, and UK Biobank (total- N = 300,486; age 16-102) and find 148 genome-wide significant independent loci (P < 5 × 10−8) associated with general cognitive function. Within the novel genetic loci are variants associated with neurodegenerative and neurodevelopmental disorders, physical and psychiatric illnesses, and brain structure. Gene-based analyses find 709 genes associated with general cognitive function. Expression levels across the cortex are associated with general cognitive function. Using polygenic scores, up to 4.3% of variance in general cognitive function is predicted in independent samples. We detect significant genetic overlap between general cognitive function, reaction time, and many health variables including eyesight, hypertension, and longevity. In conclusion we identify novel genetic loci and pathways contributing to the heritability of general cognitive function.

• Abstract The method in human genetics of ascribing causal responsibility to genotype by the use of heritability estimates has been heavily criticized over the years. It has been argued that these estimates are rarely valid and do not serve the purpose of tracing genetic causes. Recent contributions strike back at this criticism. I present and discuss two opposing views on these matters represented by Richard Lewontin and Neven Sesardic, and I suggest that some of the disagreement is based on differing concepts of genetic causation. I use the distinction of structuring and triggering causes to help clarifying the basis for the opposing views.

Out today in @NatureGenet: our paper on RDR, a novel method for estimating heritability without environment bias (https://www.nature.com/articles/s41588-018-0178-9 …). I wrote an accessible blog post explaining the paper and its implications (https://geneticvariance.wordpress.com/2018/08/13/relatedness-disequilibrium-regression-explained/ …) #geneticstweet

Alexander Young (2018). Relatedness disequilibrium regression explained. blog

• "In a- paper- [abstract and references] published today in- Nature Genetics- by myself, Augustine Kong, Kari Stefansson, and other scientists at deCODE Genetics, we introduce a novel method for estimation of heritability, Relatedness Disequilibrium Regression (RDR). Like Sib-Regression, RDR takes advantage of the variation in relatedness due to random shuffling of genes during production of sperm and eggs in parents, which we term 'relatedness disequilibrium'. The difference is, by using genetic information on parents, RDR can use the relatedness disequilibrium from all pairs of individuals in a sample, not just siblings. By using a large sample of Icelanders, we were able to estimate heritability precisely for a variety of human traits."

• It would seem that the easiest way to discredit the idea of equality is to show that people are innately, genetically, and therefore irremediably diverse and unlike. The snare is, of course, that human equality pertains to the rights and to the sacredness of life of every human being, not to bodily or even mental characteristics. Diversity is an observable fact of nature, while equality is an ethical commandment.

#reference The authors prefer to use cognitive ability instead of intelligence.

• [‘The Bell Curve’ 20 years later: A Q & A with Charles Murray. interview
• [een scan van het hele boek: https://lesacreduprintemps19.files.wordpress.com/2012/11/the-bell-curve.pdf ]
• Here are six conclusions regarding tests of cognitive ability, drawn from the classical tradition, that are by now beyond significant technical dispute:

  1. There is such a thing as a general factor of cognitive ability on which human beings differ.
  2. All standardized tests of academic aptitude or achievement measure this general factor to some degree, but IQ tests expressly designed for that purpose measure it most accurately.
  3. IQ scores match, to a first degree, whatever it is that people mean when they use the word intelligent or smart in ordinary language.
  4. IQ scores are stable, although not perfectly so, over much of a person’s life.
  5. Properly administered IQ tests are not demonstrably biased against social, economic, ethnic, or racial groups.
  6. Cognitive ability is substantially heritable, apparently no less than 40 percent and no more than 80 percent.

  The bell curve, p. 22-23

The six points illustrate the mainstream position of especially American psychologists studying differences in intelligence. It is by no means the case, as H&M claim, that there is no technical dispute. The dispute was already going on at the turn of the 20th century, and many of the arguments are still valid today. Developments in recent years (after 1994) add new arguments: the Flynn effect, the network approach (Van der Maas and others), research on experts (Ericsson and others). Remark that nowhere do H&M refer to cognitive science: their treatment of intelligence is in terms of individual differences as measured by tests of cognitive ability in the (school) population. This individual differences frame is contingent on our (school) culture. In the field of education, contemporary folk conceptions of intelligence are derived from the psychological dogmatism of, e.g., Edward Thorndike: intelligence does exist, it is a stable characteristic of the individual, therefore it must be genetic in origin.

@ 1: Yes, there is a positive manifold of cognitive abilities.

@ 2. Yes. I’d rather not call tests ‘measurements of this general factor’, though. @ 3. Yes. And that is a serious problem because what is reflected in ordinary language is folk psychology. Scientific psychology surely should not be folk psychology clad as pseudoscientific psychology. @ 4. This simply is not true. Education will make a difference. Environments make for differences, therefore changes in the environment will effect IQ scores. @ 5. IQ tests not biased? Come on. The APA Standards warn for bias! @ 6: The main question: small genetic differences get amplified in environmental dynamics. Heritability coefficients should not include those dynamics.

• Because inherited DNA variants do not change during development, polygenic scores are unique predictors in two ways. First, unlike other characteristics of the individual, DNA variants can predict individual differences in adult behaviour from birth. Second, unlike other correlations, associations between DNA variants and behaviour are causal from DNA to behaviour in the sense that there can be no backward causation from behaviour to DNA. These unique features will put genomic prediction of cognitive traits in the front line of the DNA revolution.

Genetic determinism rides again. Nathaniel Comfort (25 Sept 2018) questions a psychologist's troubling claims about genes and behaviour. [review of Blueprint: How DNA Makes Us Who We Are- Robert Plomin- Allen Lane (2018)] article

There is much criticism on this article. I wonder what the specific arguments are. e.g. Timothy Bates tweet. Paige Harden's thread https://twitter.com/kph3k/status/1044990109299486720

• But Plomin's argument provides live ammunition for those who would abandon proven methods of improving academic achievement among socio-economically deprived children. His utopia is a forensic world, dictated by polygenic algorithms and the whims of those who know how to use them. People would be defined at birth by their DNA. Expectations would be set, and opportunities, resources and experiences would be doled out — and withheld — a priori, before anyone has had a chance to show their mettle.

• Taken together, our findings suggest that both func- tional activation of the reward system, epigenetic control of dopaminergic neurotransmission, and genetic markers contribute to gIQ. Of note, the effect sizes studied are small but in the same range as previous studies (2.4%10 in previous structural imaging studies and up to 4.8%4 for previous polygenic scores).

• Our data have thus not yielded any final and conclusive answer to the heredity-environment question for personality, abilities, and intersts. The data are generally consistent with a substantial influence of the genes in accounting for individual differences in these domains, but they imply a substantial influence of the environment as well - indeed, they do not altogether exclude a completely environmentalist position. The data do, it seems to us, have something to say concerning this environment. And the upshot of what they say is that it operates in remarkably mysterious ways, given traditional views on personality and motivational development.

• It is now well-established that educational attainment is heritable33 and can be predicted from an individual's DNA34. What is less well-understood is how genetic differences between individuals lead to differences in educational outcomes. In order for genetics research to inform education policy and practice, greater knowledge is needed about the developmental and social processes that connect students' DNA to their educational outcomes35. Indeed, because polygenic scores are largely “black boxes” that aggregate genetic variants with unknown biological functions, some scientists have insisted that genetic discoveries in the area of education have no policy implications whatsoever 6

  However, our results directly connect these genetic discoveries to a common target of educational reforms - math coursetaking in secondary school. In the U.S., many states and school districts have increased the number of mathematics courses required for high school graduation37, while others have enacted policies designed to push more students into accelerated math tracks38, standardize the procedures for deciding how students are tracked39, or eliminate tracking altogether40. More generally, the U.S. government spends an estimated $3 billion on programs intended to increase STEM degree attainment41.

• Finally, with the caveat that the Add Health data represents an earlier cohort of students, our results suggest that even advantaged school contexts squander an enormous amount of potential human capital. Out of students who both had exceptional polygenic scores (+2 SD above the Add Health sample mean or the top 2% of the population distribution) and attended high status high school, about 31% took Calculus by the end of high school, whereas only 24% of students who had the same score and attended low status schools took calculus. This deficit in advanced course-taking among students with exceptional genetic propensities for succeeding in education indicates a tremendous amount of squandered human potential. The pipeline is leaking badly

• - I agree that the between-within comparison is the interesting part, and it seems to me the conclusion is very clear.

  
  So for example, a common conclusion from this lab is the GPS are about to revolutionize education. The conclusion from the between-within comparison is that making educational decisions about children on the basis of their GPS score is mostly a matter of tracking poor kids into special classes. Do we really want to do that? The enthusiasm for (behavioral) GPS needs to be tempered by what we are learning about it.

• Why, despite life's 'slings and arrows of outrageous fortune', do genetically driven differences increasingly account for differences in general cognitive ability? We suggest that the answer lies with genotype-environment correlation: as children grow up, they increasingly select, modify and even create their own experiences in part based on their genetic propensities.

28 JAN CHARLES MURRAY'S "HUMAN DIVERSITY" Posted at 14:51h in Uncategorized by Eric Turkheimer blog

Michelle N. Meyer, Patrick Turley, and Daniel J. Benjamin (Feb 3, 2020). Response to Charles Murray on Polygenic Scores. blog

• Consider IQ. IQ is not a fixed attribute of individuals and can be affected — for better and worse — by the environment in myriad ways. For example, in a society where people of color are denied access to childhood enrichment programs or adequate nutrition, a polygenic score for IQ might reflect genetic variants associated with skin pigmentation. Relatedly, in a sexist society, variants on the X and Y chromosomes, which determine biological sex, might be related to a variety of socio-economic phenotypes. Such polygenic scores would indeed moderately predict the IQ of people on average, but — and this is key — much of that predictive power would simply reflect- social- choices, not innate or immutable biology.

• For many biologists, eugenics provided a means to social stability through implementation of the biological principle that any living thing “is the product of interaction between its inheritance and its environment.”10 While marshaling statistics regarding the perceived increase in the numbers of criminals, insane persons, the feeble-minded, ant the sick, eugenicists tended to address hereditary and environmental factors. For instance, H. E. Jordan, an embryologist at the University of Virginia, in 1910 rampaged against “the social monsters - vice, crime and disease, the enemies of race improvement” before the Virginia State Conference of Charities and Correction, arguing that simple “observance of the laws of heredity and enforcement of eugenic principles” would “cure many of our social, political, and economic ills.”11 However, in this argument Jordan also included proper environment as a necessary component in the drive for social stability, explaining that a “discussion of the relative values in development of heredity and environment would be senseless. Both heredity and environment are essentials; essentials cannot be compared.” The best native abilities, Jordan emphasized, would never emerge in an unfavorable environment.12

  10 H. E. Jordan, “Heredity as a Factor in the Improvement of Social Conditions,” Amer. Breeders Mag., 2 (1991), 246-254, on p. 251. 11 Ibid., pp. 248, 253 12 Ibid., p. 251.

  Jordan's view reflected the conviction of the many biologists who found it unwise if not impossible to try to distinguish the influence of physically inherited traits from the influence of the environment. In many cases scientists viewed them as truly inseparable. In 1908, Princeton biologist Edwin Grant Conklin emphasized the inherent relationship between the two when he tried to clarify the meaning of the word “heredity.” For Conklin, heredity was “not a unique principle for it is only similarity of growth and differentiation in successive generations.”13 Conklin's view was reflected in the 1911 analysis of Frederick Adams Woods, a medical doctor and lecturer in biology at the Massachusetts Institute of Technology, who explained that many biologists doubted the possibility of separating environment and heredity. Woods himself hoped to refine scientific views of heredity and overcome the “older idea that heredity means resemblance between parent and offspring.”14 Still, for many biologists the word “heredity” was inextricably bound up with development, and could describe only past biological relationships. Moderate eugenicists, like Conklin, were aware of the difficulties involved in extricating environmental from hereditary effects, and thus advocated methods of social reform that included attention both to hereditary and environmental conditions.

• At age 10 months, genes accounted for negligible variation in mental ability across all levels of socioeconomic status (SES). However, genetic influences emerged over the course of development, with larger genetic influences emerging for infants raised in higher-SES homes. At age 2 years, genes accounted for nearly 50% of the variation in mental ability of children raised in high-SES homes, but genes continued to account for negligible variation in mental ability of children raised in low-SES homes.

Op deze abstract-pagina ook een reeks direct relevante artikelen:

• Our model posits strong reciprocal causation between phenotypic IQ and environment. That reciprocal causation produces gene X environment correlation. The model has three features that allow for potent environmental effects while accommodating high estimates of heritability.

  First, the reciprocal causation between IQ and environment leads to a positive correlation between environment and genotype that masks the potency of environment. Because of this correlation, both direct effects of genotype on IQ and indirect effects through induced environments are measured by standard heritability estimates. Judging the size of the environmental effects by the fraction of variance not explained by genotype will understate its full magnitude because to do so ignores environmental effects induced by differences in genotype. Second, reciprocal causation produces a multiplier effect that inflates both genetic and environmental advantages by a process in which higher IQ leads one into better environments causing still higher IQ, and so on. Third, we hypothesize that at least three aspects of this process lead to averaging of many environmental influences. Because of the law of large numbers, this averaging allows environmental effects to be arbitrarily large relative to the variance of an index of their combined effect—even though they seem small relative to the variance of environmental effects not correlated with genetic endowment.

• In what sense are associations between particular markers and complex behaviors made by genome-wide association studies (GWAS) and related techniques discoveries of, or entries into the study of, the causes of those behaviors? In this paper, we argue that when applied to individuals, the kinds of probabilistic 'causes' of complex traits that GWAS-style studies can point towards do not provide the kind of causal information that is useful for generating explanations; they do not, in other words, point towards useful explanations of why particular individuals have the traits that they do. We develop an analogy centered around Galton's “Quincunx” machine; while each pin might be associated with outcomes of a certain sort, in any particular trial, that pin might be entirely bypassed even if the ball eventually comes to rest in the box most strongly associated with that pin. Indeed, in any particular trial, the actual outcome of a ball hitting a pin might be the opposite of what is usually expected. While we might find particular pins associated with outcomes in the aggregate, these associations will not provide causally relevant information for understanding individual outcomes. In a similar way, the complexities of development likely render impossible any moves from population-level statistical associations between genetic markers and complex behaviors to an understanding of the causal processes by which individuals come to have the traits that they in fact have.

• Children who like to read and write tend to be better at it. This association is typically interpreted as enjoyment impacting engagement in literacy activities, which boosts literacy skills. We fitted direction-of-causation models to partial data of 3,690 Finnish twins aged 12. Literacy skills were rated by the twins' teachers and literacy enjoyment by the twins themselves. A bivariate twin model showed substantial genetic influences on literacy skills (70%) and literacy enjoyment (35%). In both skills and enjoyment, shared-environmental influences explained about 20% in each. Direction-of-causation modelling showed that skills impacted enjoyment. The influence in the other direction was zero. The genetic influences on skills influenced enjoyment, via the skills enjoyment path. This indicates active gene-environment correlation: children with an aptitude for good literacy skills are more likely to seek out literacy activities. To a lesser extent, it was also the shared-environmental influences on children's skills that propagated to influence children's literacy enjoyment. Environmental influences that foster children's literacy skills (e.g., families and schools), also foster children's love for reading and writing. These findings underline the importance of nurturing children's literacy skills.

Intergenerational Transmission of Skills (ITS) research project website

• The Intergenerational Transmission of Skills (ITS) project has developed a unique and unparalleled database, linking skills of parents to skills of children. This database- database (internally also referred to as the 'Goldmine project') currently provides information on some 25,000 parents and 41,000 of their children. In the future, this database will continue to expand with new data. The unique feature of the dataset is that skills of parents and their children were measured at the same age (both around age 12) and with the same test (a national test measuring proficiency in language and math skills). This linked dataset is enriched with extensive information on the grandparents, the parents, and the children. This makes the ITS database unique in the world.

• A joint (multi-phenotype) analysis of educational attainment and three related cognitive phenotypes generates polygenic scores that explain 11-13% of the variance in educational attainment and 7-10% of the variance in cognitive performance.

  from the abstract

• Our results also highlight two caveats to the use of the poly- genic scores in research. First, our within-family analyses suggest that GWAS estimates may overstate the causal effect sizes: if educa- tional attainment-increasing genotypes are associated with paren- tal educational attainment-increasing genotypes, which are in turn associated with rearing environments that promote educational attainment, then failure to control for rearing environment will bias GWAS estimates. If this hypothesis is correct, some of the predictive power of the polygenic score reflects environmental amplification of the genetic effects. Without controls for this bias, it is therefore inappropriate to interpret the polygenic score for educational attain- ment as a measure of genetic endowment.

• Het ligt in den aard der zaak. dat op deze decreten en privileges, in den loop der tijden door de keizers gegeven, de rechtspositie ook van de middeleeuwsche leeraren was gebaseerd. Immers met Constantinus de Groote was de christelijke kerk staatskerk en zoodoende ongemerkt ook de staatsschool christelijke school geworden.

  Van veel meer invloed op de innerlijke ontwikkeling van het schoolwezen dan deze decreten. die, het wezen van het onderwijs zelf niet raakten, was het geschrift van den vermaarden rhetor Quintilianus : De institutione oratoria. (Over de opleiding tot redenaar).

  
  Quintilianus werd omstreeks 35 n. C. in Calagurris in Spanje geboren. Reeds vroeg kwam hij naar Rome om zich tot rhetor te bekwamen. Een korten tijd was hij daar gevestigd als advocaat om al spoedig over te gaan tot het openbaar leeraarsambt. Als rhetor, leeraar in de welsprekendheid. verwierf hij zich in korten tijd zulk een vermaardheid, dat hij zich mocht verheugen in een ongekenden toeloop van leerlingen. Zijn lessen werden gevolgd door de voornaamste personen. Terwijl keizer Vespasianus hem, zooals wij reeds zagen, van staatswege had doen aanstellen als bezoldigd hoogleeraar, belastte diens tweede opvolger Domitianus hem met de opvoeding en het onderwijs van de kleinkinderen zijner zuster Domitilla. in de laatste jaren van zijn leven trof hem echter veel huiselijk leed door het verlies van zijn jonge echtgenoote en zijn zoon. Daardoor diep geschokt trok hij zich uit het openbare leven terug en schreef toen in 12 boeken zijn werk : Over de opleiding tot redenaar.
  
  De Grieken en Romeinen zagen niet, zooals wij, in de opleiding tot een bepaald vak het ideaal der opvoeding, doch in het volkomen leeren beheer-schen der taal. Met dit doel voor oogen begint Quintilianus reeds bij den zuigeling zijn regels te geven voor opvoeding en onderwijs, om dezen vervolgens op zijn ver-deren levensweg te begeleiden tot den leeftijd, waarop hij zijn intrede in het openbare leven doet als volmaakt rhetor. als almachtige bestuurder en beheerscher van het volk. Zoodoende ontwikkelt hij een wetenschappelijk systeem van op- voeding. waarin hij de practische ervaringen van een bekwaam paedagoog paart aan scherpzinnige psychologische opmerkingen en aan de resultaten van,zijn philoso-phische studiën. Vele van zijn opvoedkundige wenken heeft Quintilianus dan ook ontleend aan de geschriften der oude, vooral der Grieksche wijsgeeren. De waarde van zijn geschrift wordt hierdoor verhoogd, omdat het een samenvatting is van de opvoedkundige leerstellingen tot op zijn tijd. Het lag derhalve geheel in den aard der zaak, dat het leerboek van Quintilianus den grondslag moest vormen voor de ontwikkeling niet alleen van het Romeinsche lager en honger onderwijs, maar ook van de opvoeding in huiselijken kring. Zijn leerstellingen waren in den loop der tijden stilzwijgend wet geworden en aan zijn invloed vooral was de innerlijke ontwikkeling van het openbaar onderwijs onder de Romeinsche keizers te danken. Zijn paedagogische voorschriften werden, toen de Rorneinsche staatsschool overging in handen van de kerk, door deze overgenomen en bleven tijdens de geheele middeleeuwen van kracht. Ten tijde van de Humanisten (16e eeuw) werden zijn voorschriften door deze van onfeilbare autoriteit beschouwd en ook na de invoering der Hervorming bleven zij nog in het onderwijs-systeem der Calvinisten en jezuïeten van overwegenden invloed. Ja zelfs nog heden ten dage houden de paedagogische vraagstukken, die Quintilianus heeft opgelost of getracht heeft op te lossen, de opvoedkundigen bezig, zonder dat zij hem daarin veelal kunnen verbeteren. Het is derhalve hier de plaats om een beknopt overzicht te geven van den inhoud van dit zoo beteekenisvolle werk : Over de opleiding tot redenaar. Alle menschen, zegt Quintilianus, [Kappes, blz. 243 e.v.] brengen van nature een bepaalden aanleg en een bepaalde bekwaamheid met zich ter wereld. Activiteit en vindingrijkheid zijn ons menschen eigen, vandaar dat men gelooft, dat de ziel van goddelijken oorsprong is. Stompzinnigen en dommen worden even zeldzaam geboren als mismaakte lichamen. Het komt voor, dat groote verwachtingen, welke men van knapen had, op tateren leeftijd geheel verdwijnen. In dit geval heeft dan echter niet de natuurlijke aan-leg ontbroken, maar de zorgzame leiding Wel is waar overtreft de een den ander in begaafdheid, doch het gevolg daarvan is slechts, dat de een sneller vorderingen maakt en meer tot stand brengt dan de ander, terwijl er niemand gevonden wordt, die door oefening en vlijt niets bereikt zou hebben. Het is nu de voornaamste taak der opvoeding om den aangeboren La a n 1 eg te ontw i k k el en. Daarmede moet reeds vroeg begonnen worden. „Velen gelooven bepaald,” zegt hij (Inst. or. 1. 5. 15), „dat kinderen beneden 7 jaar nog niet onderwezen mogen worden, daar de verstandelijke vermogens van het kind op dien leeftijd zich pas zouden beginnen te ontwikkelen en zij eerst op dien leeftijd tegen de inspanning bestand zouden zijn. Beter is de opvatting van hen, die meenen, dat geen leeftijd verstoken mag blijven van zorg voor ontwikkeling, zooals die van Chrysippus, tic wel is waar

• We used analysis of pairs of genetically-related families (parents were siblings, children were cousins; N=10,913) to distinguish within-nuclear-family genetic-nurture effects from dynastic effects shared by cousins in different nuclear families. We found that indirect genetic effects on children's educational achievement were explained primarily by dynastic effects.

• There are four biologically different types of monozygous twin pairs [566]
• Though the H statistic is the simplest and most convenient way to summarize twin data on continuously varying characters, its interpretation is subject to many limitations [577]
• Probably the most important limitation of twin studies is the lack of any control over the similarities and differences of the environment of a twin pair [585]
• It is apparent that heritability and degree of genetic determination are, in general, inadequate yardsticks for measuring the relative importance of nature versus nurture [601]
• Undoubtedly, as already emphasized, the major part of the differences in height observed from one generation to the next must be environmental [609]

• Parts: I. Introduction and biological aspects - II. Comparison of fifty pairs of identical and fifty pairs of fraternal twins - III: Study of nineteen pairs of identical twins separated in infancy
• The authors have at no time conceived their problem to be to discover whether heredity or environment determines the development of the individual, nor even to derive a ratio to express, in any universal or final sense, the relative potency of the two sets of factors. The first statement of the problem is meaningless since development is always a function of of both genetic constitution and of environmental conditions. The second is indeterminate since such a ration depends upon the type of trait and the amount of variation which exists in both the genetic and the environmental factors which are compared.

She is the author of “Born Together — Reared Apart: The Landmark Minnesota Twins Study,” published in 2012 by Harvard University Press.

A Critical Introduction to Behavioral Genetics: Q&A with Sasha Gusev (2024). text

• Heritability is a tricky parameter because it involves two unintuitive concepts: variance and ratios. A trait can be strongly driven by genetics but have zero heritability because there is no genetic variance in the population being studied.

  
  Even for traits with high direct heritability, the mechanism by which genes operate may not be biological in the way most people think, because genes are still mediated by the environment. In a society where opportunities, like education, depend on skin color, the heritability of education might seem high because skin color is highly heritable. But this is not genetic causation in a biological sense—it merely reflects the structure of society.

  
  For some traits, such as educational attainment, it turns out that the direct (within-family) effects are much weaker than the total (between-family) effects. The typical genetic scores and estimates between families are thus capturing a substantial amount of external environmental influence in some form.
