A junk food diet in early years slightly decreases IQ

This has been all over the news this week.

Are dietary patterns in childhood associated with IQ at 8 years of age? A population-based cohort study

Background Little is known about the effects of overall diet in childhood and intelligence later in life.

Methods The current study, based on the Avon Longitudinal Study of Parents and Children, uses data on children’s diet reported by parents in food-frequency questionnaires at 3, 4, 7 and 8.5 years of age. Dietary patterns were identified using principal-components analysis and scores computed at each age. IQ was assessed using the Wechsler Intelligence Scale for Children at 8.5 years. Data on a number of confounders were collected, and complete data were available for 3966 children.

Results After adjustment, the ‘processed’ (high fat and sugar content) pattern of diet at 3 years of age was negatively associated with IQ assessed at 8.5 years of age—a 1 SD increase in dietary pattern score was associated with a 1.67 point decrease in IQ (95% CI −2.34 to −1.00; p<0.0001). The ‘health-conscious’ (salad, rice, pasta, fish, fruit) pattern at 8.5 years was positively associated with IQ: a 1 SD increase in pattern score led to a 1.20 point increase in IQ (95% CI 0.52 to 1.88; p=0.001).

Conclusion There is evidence that a poor diet associated with high fat, sugar and processed food content in early childhood may be associated with small reductions in IQ in later childhood, while a healthy diet, associated with high intakes of nutrient rich foods described at about the time of IQ assessment may be associated with small increases in IQ.

I suspect the issue isn’t the fat, or even the sugar, but low levels of nutrients like omega three oils, vitamins and minerals. This whole study has a slight ‘duh’ quality to it, although I was surprised it made as little difference to the final IQ as it did. I’m glad now that I got my kids to eat all that homemeade fish pie.

Genes account for 50% of classroom performance.

News of the day; your genes have a strong effect on how you perform at school. Not exactly shocking.

Added Value Measures in Education Show Genetic as Well as Environmental Influence

Does achievement independent of ability or previous attainment provide a purer measure of the added value of school? In a study of 4000 pairs of 12-year-old twins in the UK, we measured achievement with year-long teacher assessments as well as tests. Raw achievement shows moderate heritability (about 50%) and modest shared environmental influences (25%). Unexpectedly, we show that for indices of the added value of school, genetic influences remain moderate (around 50%), and the shared (school) environment is less important (about 12%). The pervasiveness of genetic influence in how and how much children learn is compatible with an active view of learning in which children create their own educational experiences in part on the basis of their genetic propensities.

This is a massive study, involving  8,000 children  both MZ and DZ twins. An interesting snippet from it…

Previous twin studies on school performance have indicated moderate heritability around 40–60% [10], [11], [12], [13]. Studies specifically focusing on reading abilities show a similar pattern of results with moderate to high heritability and modest shared environmental influences [14], [15]. More recently, studies have also included mathematical abilities, which typically show high heritabilities around 60–70% [16], [17]. A striking finding is that genetic influences appear to have largely generalist effects across diverse cognitive and academic abilities [18], [19]. For example, the average genetic correlation (an index of the degree to which genetic influences on one trait also influence another trait) between diverse cognitive and academic domains was 0.70 in a recent review.

I’d like to say from personal observation.. the parents of the better performing kids at my own children’s school are almost uniformly from a higher than average SES group; the ‘nice’ parents, while the those struggling mainly seem to be the children of the underclass. My own little darlings are (I risk being snobbish) both a couple of years ahead of the norm, which matches very well with both my partner and I being in the tiny ‘top’ group at our school, and both being able to read at a pre school age. Really, it would be surprising if there wasn’t a genetic component to classroom performance, as IQ is substantially inherited, as are behavioural conditions like ADHD.

The ‘Flynn effect’ is caused by nutrition

Or at least, it is according to Professor Lynn. The Flynn effect is the rise in IQ that was observed over the twentieth century, mostly in developed nations, as the overall standard of living improved. It stabilised in Europe in the eighties, but in places like East Asia it is still rising as the countries modernise.

What has caused the Flynn effect? Secular increases in the Development Quotients of infants

Richard Lynn,

University of Ulster, Coleraine, Northern Ireland, BT52 1SA, UK

Received 23 March 2008;  revised 17 July 2008;  accepted 17 July 2008.  Available online 21 September 2008.

Abstract
Results of five studies show that during the second half of the twentieth century there were increases in the Development Quotients (DQs) of infants in the first two years of life. These gains were obtained for the Bayley Scales in the United States and Australia, and for the Griffiths Test in Britain. The average of 19 data points is a DQ gain of approximately 3.7 DQ points per decade. Similar gains of approximately 3.9 IQ points per decade have been present among preschool children aged 4–6 years. These gains are about the same as the IQ gains of school age students and adults on the Wechsler and Binet tests. This suggests that the same factor has been responsible for all these secular gains. This rules out improvements in education, greater test sophistication, etc. and most of the other factors that have been proposed to explain the Flynn effect. It is proposed that the most probable factor has been improvements in pre-natal and early post-natal nutrition.

Prior to the modern era, Victorians were four inches shorter than the current population, and the IQ was thirty points lower. It would seem reasonable that both increases were proved by a combination of improved nutrition and health care. The greatest IQ rises were seen in the lowest IQ ranges, suggesting that the welfare state, in the UK at least, has contributed to our being geniuses compared to our great grandparents.

The IQ rise has only been observed in our ‘fluid’ intelligence, AKA our reasoning abilities. Our memory seems to have been unaffected by the rise in IQ. I suppose this could mean that as a species learning is a lot more important than reasoning, so our resources are directed towards constructing our memory fully before our problem solving wiring is even begun.

What the average psychologist really thinks about race and IQ.

I mean, the average psychologist on the street.

Last year when the whole Watson fiasco hit the fan, I found myself patiently explaining to my outraged relatives that there was actually an IQ gap, and showing them the signed statement to that effect that was recognised by mainstream psychologists.

Mainstream Science on Intelligence

Since the publication of “The Bell Curve,” many commentators have offered opinions about human intelligence that misstate current scientific evidence. Some conclusions dismissed in the media as discredited are actually firmly supported.

This statement outlines conclusions regarded as mainstream among researchers on intelligence, in particular, on the nature, origins, and practical consequences of individual and group differences in intelligence. Its aim is to promote more reasoned discussion of the vexing phenomenon that the research has revealed in recent decades. The following conclusions are fully described in the major textbooks, professional journals and encyclopedias in intelligence.

The Meaning and Measurement of Intelligence

Intelligence is a very general mental capability that, among other things, involves the ability to reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly and learn from experience. It is not merely book learning, a narrow academic skill, or test-taking smarts. Rather, it reflects a broader and deeper capability for comprehending our surroundings–“catching on,” “making sense” of things, or “figuring out” what to do.

Intelligence, so defined, can be measured, and intelligence tests measure it well. They are among the most accurate (in technical terms, reliable and valid) of all psychological tests and assessments. They do not measure creativity, character personality, or other important differences among individuals, nor are they intended to.

While there are different types of intelligence tests, they all measure the same intelligence. Some use words or numbers and require specific cultural knowledge (like vocabulary). Others do not, and instead use shapes or designs and require knowledge of only simple, universal concepts (many/few, open/closed, up/down).

The spread of people along the IQ continuum, from low to high, can be represented well by the bell curve (in statistical jargon, the “normal curve”). Most people cluster around the average (IQ 100). Few are either very bright or very dull: About 3% of Americans score above IQ 130 (often considered the threshold for “giftedness”), with about the same percentage below IQ 70 (IQ 70-75 often being considered the threshold for mental retardation).

Intelligence tests are not culturally biased against American blacks or other native-born, English-speaking peoples in the U.S. Rather, IQ scores predict equally accurately for all such Americans, regardless of race and social class. Individuals who do not understand English well can be given either a nonverbal test or one in their native language.

The brain processes underlying intelligence are still little understood. Current research looks, for example, at speed of neural transmission, glucose (energy) uptake, and electrical activity of the brain, uptake, and electrical activity of the brain.
Group Differences

Members of all racial-ethnic groups can be found at every IQ level. The bell curves of different groups overlap considerably, but groups often differ in where their members tend to cluster along the IQ line. The bell curves for some groups (Jews and East Asians) are centered somewhat higher than for whites in general. Other groups (blacks and Hispanics) are centered somewhat lower than non-Hispanic whites.

The bell curve for whites is centered roughly around IQ 100; the bell curve for American blacks roughly around 85; and those for different subgroups of Hispanics roughly midway between those for whites and blacks. The evidence is less definitive for exactly where above IQ 100 the bell curves for Jews and Asians are centered.
Practical Importance

IQ is strongly related, probably more so than any other single measurable human trait, to many important educational, occupational, economic, and social outcomes. Its relation to the welfare and performance of individuals is very strong in some arenas in life (education, military training), moderate but robust in others (social competence), and modest but consistent in others (law-abidingness). Whatever IQ tests measure, it is of great practical and social importance.

A high IQ is an advantage in life because virtually all activities require some reasoning and decision-making. Conversely, a low IQ is often a disadvantage, especially in disorganized environments. Of course, a high IQ no more guarantees success than a low IQ guarantees failure in life. There are many exceptions, but the odds for success in our society greatly favor individuals with higher IQs.

The practical advantages of having a higher IQ increase as life settings become more complex (novel, ambiguous, changing, unpredictable, or multifaceted). For example, a high IQ is generally necessary to perform well in highly complex or fluid jobs (the professions, management): it is a considerable advantage in moderately complex jobs (crafts, clerical and police work); but it provides less advantage in settings that require only routine decision making or simple problem solving (unskilled work).

Differences in intelligence certainly are not the only factor affecting performance in education, training, and highly complex jobs (no one claims they are), but intelligence is often the most important. When individuals have already been selected for high (or low) intelligence and so do not differ as much in IQ, as in graduate school (or special education), other influences on performance loom larger in comparison.

Certain personality traits, special talents, aptitudes, physical capabilities, experience, and the like are important (sometimes essential) for successful performance in many jobs, but they have narrower (or unknown) applicability or “transferability” across tasks and settings compared with general intelligence. Some scholars choose to refer to these other human traits as other “intelligences.”
Source and Stability of Within-Group Differences

Individuals differ in intelligence due to differences in both their environments and genetic heritage. Heritability estimates range from 0.4 to 0.8 (on a scale from 0 to 1), most thereby indicating that genetics plays a bigger role than does environment in creating IQ differences among individuals. (Heritability is the squared correlation of phenotype with genotype.) If all environments were to become equal for everyone, heritability would rise to 100% because all remaining differences in IQ would necessarily be genetic in origin.

Members of the same family also tend to differ substantially in intelligence (by an average of about 12 IQ points) for both genetic and environmental reasons. They differ genetically because biological brothers and sisters share exactly half their genes with each parent and, on the average, only half with each other. They also differ in IQ because they experience different environments within the same family.

That IQ may be highly heritable does not mean that it is not affected by the environment. Individuals are not born with fixed, unchangeable levels of intelligence (no one claims they are). IQs do gradually stabilize during childhood, however, and generally change little thereafter.

Although the environment is important in creating IQ differences, we do not know yet how to manipulate it to raise low IQs permanently. Whether recent attempts show promise is still a matter of considerable scientific debate.

Genetically caused differences are not necessarily irremediable (consider diabetes, poor vision, and phenal keton uria), nor are environmentally caused ones necessarily remediable (consider injuries, poisons, severe neglect, and some diseases). Both may be preventable to some extent.
Source and Stability of Between-Group Differences

There is no persuasive evidence that the IQ bell curves for different racial-ethnic groups are converging. Surveys in some years show that gaps in academic achievement have narrowed a bit for some races, ages, school subjects and skill levels, but this picture seems too mixed to reflect a general shift in IQ levels themselves.

Racial-ethnic differences in IQ bell curves are essentially the same when youngsters leave high school as when they enter first grade. However, because bright youngsters learn faster than slow learners, these same IQ differences lead to growing disparities in amount learned as youngsters progress from grades one to 12. As large national surveys continue to show, black 17- year-olds perform, on the average, more like white 13-year-olds in reading, math, and science, with Hispanics in between.

The reasons that blacks differ among themselves in intelligence appear to be basically the same as those for why whites (or Asians or Hispanics) differ among themselves. Both environment and genetic heredity are involved.

There is no definitive answer to why IQ bell curves differ across racial-ethnic groups. The reasons for these IQ differences between groups may be markedly different from the reasons for why individuals differ among themselves within any particular group (whites or blacks or Asians). In fact, it is wrong to assume, as many do, that the reason why some individuals in a population have high IQs but others have low IQs must be the same reason why some populations contain more such high (or low) IQ individuals than others. Most experts believe that environment is important in pushing the bell curves apart, but that genetics could be involved too.

Racial-ethnic differences are somewhat smaller but still substantial for individuals from the same socioeconomic backgrounds. To illustrate, black students from prosperous families tend to score higher in IQ than blacks from poor families, but they score no higher, on average, than whites from poor families.

Almost all Americans who identify themselves as black have white ancestors-the white admixture is about 20%, on average–and many self-designated whites, Hispanics, and others likewise have mixed ancestry. Because research on intelligence relies on self- classification into distinct racial categories, as does most other social-science research, its findings likewise relate to some unclear mixture of social and biological distinctions among groups (no one claims otherwise).
Implications for Social Policy

The research findings neither dictate nor preclude any particular social policy, because they can never determine our goals. They can, however, help us estimate the likely success and side-effects of pursuing those goals via different means.

 It was actually quite amusing watching the media trying to tip toe around the well known fact that black Americans IQ’s are about 20 points lower than Asian Americans. Also, most people think that IQ tests have been shown to be meaningless and not a good measure of intelligence, probably due to Gould being promoted as ‘right’. Which is strange, since among Goulds qualifications, I don’t recall seeing a psychology degree.

Upon a scan through the WIki item on IQ and race (hey, I needed to find the name of something) I found an interesting study on how the media reports on matters to do with IQ and race, called the Snyderman and Rothman study. It was carried out in 1987, surveying 1,020 scholars in specialties that would give them reason to be knowledgeable about IQ. The report stated…

This is perhaps the central question in the IQ controversy. Respondents were asked to express their opinion of the role of genetic differences in the black-white IQ differential. Forty-five percent believe the difference to be a product of both genetic and environmental variation, compared to only 15% who feel the difference is entirely due to environmental variation. Twenty-four percent of experts do not believe there are sufficient data to support any reasonable opinion, and 14% did not respond to the question. Eight experts (1%) indicate a belief in an entirely genetic determination.

Interestingly, the respondents placed themselves as slightly left wing politically. The study claimed that the media misrepresented the views of the mainstream scientists (as it does with race). It put forward the views of people like Gould as the mainstream (ie; no such thing as race, g is meaningless, no racial differences in IQ) but claimed people like Jensen were a minority, when they were actually the mainstream.

Also interesting, in a similar vein, was that in the nineties when polled, 65% of anthropologists supported race as a concept, but  the media resolutely insisted that they claimed the opposite. Probably because the American anthropological society released a statement saying ‘there’s no such thing as race’ around the same time. I’m guessing, politics was driving that statement.

My biggest argument against it ‘all being environment’ is that semi-literate malnourished Asian peasants score better than black Americans. What environmental argument can account for that?

Anyway, here is a letter from Linda Gottfredson (renowned and respected psychologist), who wrote on the subject.

Egalitarian fiction and collective fraud.

Linda S. Gottfredson
Society, March-April 1994 v31 n3 p53(7)

Linda S. Gottfredson is professor of educational studies at the University of Delaware and co-director of the Project for the Study of Intelligence and Society. She has published widely on fairness in testing and racial inequality, focusing most recently on race-norming and the dilemmas in managing workforce diversity. Her current work examines social policy based on the egalitarian fiction.

Social science today condones and perpetuates a great falsehood – one that undergirds much current social policy. This falsehood, or “egalitarian fiction,” holds that racial-ethnic groups never differ in average developed intelligence (or, in technical terms, g, the general mental ability factor). While scientists have not yet determined their source, the existence of sometimes large group differences in intelligence is as well-established as any fact in the social sciences. How and why then is this falsehood perpetrated on the public? What part do social scientists themselves play, deliberately or inadvertently, in creating and maintaining it? Are some of them involved in what might be termed “collective fraud?” Intellectual dishonesty among scientists and scholars is, of course, nothing new. But watchdogs of scientific integrity have traditionally focused on dishonesty of individual scientists, while giving little attention to the ways in which collectivities of scientists, each knowingly shaving or shading the truth in small but similar ways, have perpetuated frauds on the scientific community and the public at large. Perhaps none of the individuals involved in the egalitarian fiction could be accused of fraud in the usual sense of the term. Indeed, I would be the first to say that, like other scientists, most of these scholars are generally honest. Yet, their seemingly minor distortions, untruths, evasions, and biases collectively produce and maintain a witting falsehood. Accordingly, my concern here is to explore the social process by which many otherwise honest scholars facilitate, or feel compelled to endorse, a scientific lie.

The Egalitarian Fiction
It is impossible here to review the voluminous evidence showing that racial-ethnic differences in intelligence are the rule rather than the exception (some groups performing better than whites and others worse), and that the well-documented black-white gap is especially striking. All groups span the continuum of intelligence, but some groups contain greater proportions of individuals that are either gifted or dull than others. Three facts regarding these group differences are of particular importance here for together they contradict the claim that there are no meaningful group differences. Racial-ethnic differences in intelligence are real. The large average group differences in mental test scores in the United States do not result from test bias, which is minuscule overall, as even a National Academy of Science panel concluded in 1982. Moreover, intelligence and aptitude tests measure general mental abilities, such as reasoning and problem solving, not merely accumulated bits of knowledge – and thus tap what experts and laymen alike view as “intelligence.”

Regardless of how we choose to construe them, differences in intelligence are of great practical importance. Overall they predict performance in school and on the job better than any other single attribute or condition we have been able to measure. Intelligence certainly is not the only factor that affects performance, but higher levels of intelligence greatly increase people’s odds of success in many life settings. Group disparities in intelligence are stubborn. Although individuals fluctuate somewhat in intelligence during their lives, differences among groups seem quite stable. The average black-white difference, for example, which appears by age six, has remained at about 18 Stanford-Binet IQ points since it was first measured in large national samples over seventy years ago. It is not clear yet why the disparities among groups are so stubborn – the reasons could be environmental, genetic, or a combination of both – but so far they have resisted attempts to narrow them. Although these facts may seem surprising, most experts on intelligence believe them to be true but few will acknowledge their truth publicly.

Misrepresentation of Expert Opinion
The 1988 book The IQ Controversy: The Media and Public Policy by psychologist-lawyer Mark Snyderman and political scientist Stanley Rothman provides strong evidence that the general public receives a highly distorted view of opinion among “IQ experts.” In essence, say Snyderman and Rothman, accounts in major national newspapers, newsmagazines, and television reports have painted a portrait of expert opinion that leaves the impression that “the majority of experts in the field believe it is impossible to adequately define intelligence, that intelligence tests do not measure anything that is relevant to life performance, and that they are biased against minorities, primarily blacks and Hispanics, as well as against the poor.” However, say the authors, the survey of experts revealed quite the opposite: On the whole, scholars with any expertise in the area of intelligence and intelligence testing … share a common view of [what constitute] the most important components of intelligence, and are convinced that [intelligence] can be measured with some degree of accuracy. An overwhelming majority also believe that individual genetic inheritance contributes to variations in IQ within the white community, and a smaller majority express the same view about the black-white and SES [socioeconomic] differences in IQ.

Unfortunately, such wholesale misrepresentation of expert opinion is not limited to the field of intelligence, as Rothman has shown in parallel studies of other policy-related fields such as nuclear energy or environmental cancer research. However, the study of IQ experts revealed something quite surprising. Most experts’ private opinions mirrored the conclusions of psychologist Arthur Jensen, whom the media have consistently painted as extreme and marginal for holding precisely those views. As Snyderman and Rothman point out, the experts disclosed their agreement with this “controversial” and putatively marginal position only under cover of anonymity. No one, not even Jensen himself, had any inkling that his views now defined the mainstream of expert belief. Although Jensen regularly received private expressions of agreement, he and others had been, as Snyderman and Rothman note, widely castigated by the expert community for expressing some of those views.

Several decades ago, most experts, among them even Jensen, believed many of the views that the media now wrongly describe as mainstream – for example, that cultural bias accounts for the large black-white differences in mental test scores. While the private consensus among IQ experts has shifted to meet Jensen’s “controversial” views, the public impression of their views has not moved at all. Indeed, the now-refuted claim that tests are hopelessly biased is treated as a truism in public life today. The shift in private, if not public, beliefs among IQ experts is undoubtedly a response to the overwhelming weight of evidence which has accumulated in recent decades on die reality and practical importance of racial-ethnic differences in intelligence. This shift is by all indications a begrudging one, and certainly no flight into “racism.”

Snyderman and Rothman found that as many IQ experts as journalists and science editors (two out of three) agreed with the statement that “strong affirmative action measures should be used in hiring to assure black representation.” Fully 63 percent of the IQ experts described themselves as liberal politically, 17 percent as middle of the road, and 20 percent as conservative – not much different than the results for journalists (respectively, 64, 21, and 16 percent). Moreover, as Snyderman and Rothman suggest (and as is consistent with personal accounts by Jensen and others), many of the surveyed experts, while agreeing with Jensen’s conclusions, may disapprove of his expressing these conclusions openly. Consistent with this, when queried about their respect for the work of fourteen individuals who have written about intelligence or intelligence testing, the IQ experts rated Jensen only above the widely but apparently unjustly) vilified Cyril Burt. Despite the fact that most agreed with Jensen, they rated him far lower than often like-minded psychometricians who had generally stayed clear of the fray. Jensen even received significantly lower ratings than his vocal critics, such as psychologist Leon Kamin, whose scientific views are marginal by the experts’ own conclusions. By contrast, the experts in environmental cancer research behaved as one would expect; they gave higher reputational ratings to peers who are closer to the mainstream than to high-profile critics. Snyderman’s and Rothman’s findings therefore suggest that a high proportion of experts are misrepresenting their beliefs or are keeping silent in the face of a public falsehood. It is no wonder that the public remains misinformed on this issue.

Living Within a Lie
IQ experts feel enormous pressure to “live within a lie,” to use a phrase by Czech writer and leader Vaclav Havel characterizing daily life under communist rule n Eastern Europe. Havel argued, in The Power of the Powerless, that, by living a lie, ordinary citizens were complicit in their own tyranny. Every greengrocer, every clerk who agreed to display official slogans not reflecting his own beliefs, or who voted in elections known to be farcical, or who feigned agreement at political meetings, normalized falsification and tightened the regime’s grip on thought. Each individual who lived the lie, who capitulated to “ideological pseudo-reality,” became a petty instrument of the regime. As many commentators have noted, Americans may not speak certain truths about racial matters today. To adapt a phrase, there is a “structured silence.”

Social scientists had already begun subordinating scientific norms to political preferences and creating much of our current pseudo-reality on race by the mid-1960s. Sociologist Eleanor Wolf, in a 1972 article in Race, for example, detailed her distress at how fellow social scientists were misusing research data to support particular positions on civil rights policy: presenting inconclusive data as if it were decisive; lacking candor about “touchy” subjects (such as the undesirable behavior of lower-class students); blurring or shaping definitions (segregation, discrimination, racism) to suit “propagandistic” purposes; making exaggerated claims about the success of favored policies (compensatory education and school integration) while minimizing or ignoring contrary evidence. As a result, social science and social policy are now dominated by the theory that discrimination accounts for all racial disparities in achievements and well-being. This theory collapses, however, if deprived of the egalitarian fiction, as does the credibility of much current social policy. Neither could survive intact if their central premise were scrutinized.

No wonder, then, that IQ researchers find themselves under great professional and institutional pressure to avoid not only engaging in such scrutiny but even appearing to countenance it. The scrutiny itself must be discredited; the egalitarian fiction must be raised above serious scientific question. Scientists must at least appear to believe the dogma. As was the case in Havel’s communist-dominated Eastern Europe, in American academe feigned belief in the official version of reality is maintained largely by routine obeisance of academics as they pursue their own ambitions.

Scholars realize their scholarly ambitions primarily through other scholars. Peer recognition is the currency of academic and scientific life. It is crucial to a scholarly reputation and all the steps toward status and success – publications, professional invitations and awards, promotion, tenure, grants, fellowships, election to professional office, appointment to prestigious panels. One’s ability even to carry out certain kinds of research, funded or not, may be contingent upon peer recognition and respect – for instance, getting collaborators, subjects, or cooperation from potential research sites. Just as in personal life, a high professional reputation depends upon a sustained history of “appropriate” behavior, and it may be irreparably damaged by hints of scandal or impropriety. Similarly, the reputations of scientists and their organizations are enhanced or degraded by those for whom they show regard and approval. Associating oneself with highly regarded individuals or ideas enhances, even if slightly, one’s own status.

Awarding an honor to a luminary can enhance the reputation of one’s own organization, especially if the recipient accepts the honor with genuine appreciation. By the same token, one risks “staining” one’s reputation by associating with, honoring, defending, or even failing to condemn the “wrong” sort of individual or idea. In short, how one gives or withholds one’s regard is important for one’s professional reputation because it affects the regard one receives. Such a social system enhances the integrity of science and is furthered by personal ambition when the members of the community base their regard on scholarly norms, such as competence, creativity, and intellectual rigor. However, such a system breeds intellectual corruption when members systematically subordinate scientific norms to other considerations – money, politics, religion, fear. This is what appears to be happening today in the social sciences on matters of race and intelligence. As sociologist Robert Gordon argues, social science has become “one-party science.”

Democrat or Republican, liberal or conservative, virtually all American intellectuals publicly adhere to, if not espouse, the egalitarian fiction. And many demonstrate their party loyalty by enforcing the fiction in myriad small ways in their academic routine, say, by off-handedly dismissing racial differences in intelligence as “a racist claim, of course,” criticizing authors for “blaming the victim,” or discouraging students and colleagues from doing “sensitive” research. One can feel the gradient of collective alarm and disapproval like a deepening chill as one approaches the forbidden area. Researchers who cross the line occasionally face overt censorship, or calls for it. For example, one prominent (neoconservative) editor rejected an author’s paper, despite finding it scientifically sound, because there are social “considerations” which “overweigh the claims of social science.” Another eminent editor, after asking an author to soften the discussion in his article, recently published the revised paper with an editorial postscript admonishing scientists in the field to find a “balance” between the need for free exchange of research results on intelligence and the (presumably comparable) “need” that “no segment of our society. . .feel threatened” by it.

Covert and Overt Censorship
Whether motivated by a sincere concern over supposedly “dangerous” ideas or by a desire to distance themselves publicly from unpopular ideas, editors who use such non-academic standards discourage candor and stifle debate. They deaden social science by choking off one source of the genuine differences of opinion that are its lifeblood. Overt censorship of research is uncommon, probably because it is an obvious affront to academic norms. Less striking forms of censorship directly affect many more academics, however, and so may be more important. Easier to practice without detection and to disguise as “academic judgment,” they serve to keep scholars from pursuing ideas that might undermine the egalitarian dogma.

A less obvious form of censorship, which has become somewhat common recently, is indirect censorship. It is accomplished when academic or scientific organizations approve some views but repudiate or burden others on ideological grounds. Sometimes the ideological grounds are explicit Campus speech codes are a well-known example which, had they been upheld in the courts, would have made repudiation of the egalitarian fiction a punishable offense on some campuses. The earlier (unsuccessful) attempt to include possible “offense to minority communities” as grounds for refusing human subjects approval is another example.

Gordon reports yet others, including the National Institutes of Health’s new extra layer of review for politically “sensitive” grant proposals and the University of Delaware’s recent policy (reversed by a national arbitrator) of banning a particular funding source because, so the university claimed, it supports research on race which “conflicts with the university’s mission to promote racial and cultural diversity.” Gordon also outlines in detail – as political scientist Jan Blits has done – the covert application of ideological standards to facilitate expression of some views but burden others. This form of indirect censorship, also falling under the rubric of “political correctness,” occurs when university administrators, faculty, or officers of professional associations disguise as “professional judgment” an ideological bias in their enforcing of organizational rules, extending faculty privileges, protecting faculty rights, and weighing evidence in faculty promotions and grievances.

Recently, some American universities have invoked “professional judgment” as a pretext for reclassifying “controversial” scholarly publications in their annual merit reviews as “non-research,” to misrepresent outside peer reviews in evaluating controversial professionals up for promotion, and to limit student access to these professors. Such thinly veiled bias publicly demonstrates the officials’ own adherence to the prescribed institutional attitudes and their willingness to enforce them, not only protecting those officials from protest but also encouraging fellow members of the institution to toe the line.

Covert censorship is far more common than overt or indirect censorship. It consists of bias in the application of scientific norms when reviewers evaluate their peers’ work for funding, publication, presentation, or dissemination. Individual ideological biases are found in all fields, of course, but the hope is that such biases remain small and will cancel each other out over the long run-hence the importance of a free and open exchange of data, theories, and results. What I have in mind is systematic bias and a pervasive double standard which impedes one line of research and accords another undeserved hegemony. In one-party science, the disfavored line of work is subjected to intense scrutiny and nearly impossible standards, while the favored line of work is held to lax standards in which flaws are overlooked (called “oversight bias” in the psychological literature). Similarly, the disfavored idea is rejected unless it is “balanced” by including proponents of the favored view (even if that view is the equivalent of “flat-earth theory”), where the favored line of work is readily accepted for publication or presentation, even when it totally ignores the opposing literature. Getting a controversial paper accepted under such circumstances often becomes a test of endurance between the editor and reviewers (in coming up with criticisms) and the author (in rebutting them). Submitting IQ research or grant proposals outside the narrowest professional confines exposes intelligence researchers to yet other biases, usually of the kind to which reviewers of the proposals will accept no rebuttal.

The broader circle of critics in the social sciences often implicitly dismisses the legitimacy of research on intelligence itself by arguing that “intelligence” is undefinable or unmeasurable – as if the critics’ own favored constructs (social class, culture, self-concept, anxiety, and so on) were as well validated and operationalized. Others now also seek to deny IQ researchers (but not themselves) use of the concept “race” because, they assert, race is not a biological condition, but is socially constructed. The double standards can even ricochet back and forth, depending on the particular question being considered. Gordon recalls how sociologists failed to criticize sociologist James Coleman for omitting student ability from his analyses of school integration (which led to overstating the impact of integrated schools on black achievement-for sociologists a favorable outcome), but how they criticized him roundly for the very same omission in analyses of private versus public schools,(which led to overstating the impact of private schools on black achievement – an unfavorable outcome). In short, in one-party science, scientific regard flows like political patronage to loyal and active party members, who can demonstrate their loyalty by being alert to hints of dissidence. Like all one-party political systems, one-party science becomes intellectually corrupt and arrogant as it gains confidence in its power.

The most insidious corruption to which one-party science leads is pervasive self-censorship, what involved researchers generally prefer to regard as “prudence” or “avoiding unnecessary trouble.” Coleman has drawn particular attention to the problem of “self-suppression “the impulse not to ask the crucial question” – in research on race. In an example from his own research for the influential “Coleman Report,” he describes his failure to conduct important analyses that might have produced embarrassing findings about the abilities of black teachers. Another way of avoiding unwanted results is to ignore certain data, subjects, or variables. Or unwanted results can be omitted, buried in footnotes, explained away, or simply ignored in one’s conclusions. The most subtle form of self-censorship is deliberate avoidance of making crucial connections, or denying them. Psychologist Richard Herrnstein has noted that it was his drawing out the implications of one such connection, namely, that some portion of (white) social class differences in intelligence is genetic, that sparked his public excoriation in the 1970s.

Normally, scholars are eager to explicate illuminating connections between subspecialties. They are reluctant to do so, however, when these connections put in question the egalitarian dogma on race. Virtually all sociologists and economists ignore the literature on intelligence despite its central importance to core issues in their disciplines, such as inequalities in occupation and income. Researchers in the various subfields of intelligence obviously cannot ignore the literature with impunity. Yet they, too, often prefer to stay strictly within the confines of their specialties rather than making crucial, but unpopular, connections, or they use language that obscures what otherwise would be quite obvious.

Many psychometricians, especially those working for large testing organizations, avoid referring to “intelligence” and often seem reluctant to say much about the practical or theoretical meaning of the racial differences they observe on unbiased tests. But even remaining within one’s subfield is often not enough, for the field of intelligence itself is widely suspect. Hence some scholars explicitly disavow unpopular connections that critics might attribute to them. For example, they will argue in favor of the importance of intelligence for scholastic performance but then assure their readers, over-optimistically, that the racial gap “seems to be closing rapidly.” The tenor of these preemptive disclaimers is clear. While researchers in any field may lightly dismiss the credibility of key connections regarding race and intelligence, no one ever lightly endorses their credibility with impunity. Even those of us committed to candor are exceedingly cautious when expressing informed opinions on certain topics, especially the genetics of race. Thus, publicly stated opinions of researchers about matters outside their subfields tend in one direction – to dispute or undercut the facts necessary for toppling the egalitarian fiction. What may be tolerable behavior at the individual level becomes intolerable bias at the aggregate level. Censorship – even self-censorship – requires justification, or at least apparent justification.

On the whole, those who would squelch open inquiry of the egalitarian fiction base their justification on two assertions: 1) Research on racial differences in intelligence has already been scientifically “discredited.” 2) Inquiry into racial differences is immoral.

Point one asserts that the egalitarian premise is absolute truth and hence beyond scientific scrutiny. Point two is indifferent to its truth. Both counsel outrage at the very thought of the research. The claim that the research has been discredited rests largely on extensive misrepresentation that is often embarrassingly crude or casual – for example, contradicting arguments an author never made, while ignoring what was actually stated; attributing policy preferences to an author which are opposite of what the author actually expressed; or simply alleging fraud or gross incompetence without any substantiation whatsoever. The claim that the research is immoral rests squarely on the view that, regardless of the truth, the study itself can only be harmful. In fact, some critics assert (mostly privately) that the greater the truth, the greater the danger it poses to lower-scoring groups, and thus the greater the need to suppress it.

Despite their differences, both justifications for censorship often take the form of demonizing open inquiry by labeling it (and the people who practice it) as “dangerous,” “fascist,” “ideological,” or “racist.” The study of race and intelligence is something, they tell us, that no decent person – let alone a serious scientist – would ever do and that every decent person and serious researcher would oppose. Thus, in a kind of Orwellian inversion, marked by what Gordon calls “high talk and low blows,” the suppression of science presents itself as science itself. Intellectual dishonesty becomes the handmaiden of social conscience, and ideology is declared knowledge while knowledge is dismissed as mere ideology. Neither social policy, nor science, nor society itself is served well by scientific silence on racial differences in intelligence.

Enforcement of the egalitarian fiction has tragic consequences, especially for blacks. The outcomes are even worse than researchers of intelligence predicted two decades ago. The falsehood, because it tries to defy a reality that has conspicuous repercussions in daily life, is doing precisely what it was meant to avoid: producing pejorative racial stereotypes, fostering racial tensions, stripping members of lower-scoring groups of their dignity and incentives to achieve, and creating permanent social inequalities between the races. Enforcement of the lie is gradually distorting and degrading all institutions and processes where intelligence is at least somewhat important (which is practically everywhere) but especially where it is most important (in public schools, higher education, the professions, and high-level executive work). The falsehood requires that there be racial preferences and that their use be disguised, wherever intelligence has at least moderate importance. Society is thus being shaped to meet the dictates of a collective fraud. The fiction is aiding and abetting bigots to a fat greater degree than any truth ever could, because its specific side-effects – racial preferences, official mendacity, free-wielding accusations of racism, and falling standards – are creating deep cynicism and broad resentment against minorities, blacks in particular, among the citizenry.

Enforcement of the egalitarian fiction is not a moral or scientific imperative; it is merely political. It is terribly short-sighted, for it corrupts both science and society. However, just as the fiction is sustained by small untruths, so can it be broken down by many small acts of scientific integrity. This requires no particular heroism. All that is required is for scientists to act like scientists-to demand, clearly and consistently, respect for truth and for free inquiry in their own settings, and to resist the temptation to win easy approval by endorsing a comfortable lie.

Go Linda. Nothing based on a lie will fare well.

Atheists, the religious, and their behaviours compared.

I haunt the ‘religion and spirtuality’ section of yahoo answers. This has lead me to the observation that many Americans sincerely believe that all atheists are conscienceless materialists, willing to murder good Christian babies for a laugh, devoid of any kind of morality.

This is something of a strange viewpoint. Atheism is considered ‘pretty normal’ in Europe. In fact, there are a few countries now where atheists are the majority. Religion is much less of an issue here. Partly because we bundled all our religious fruitcakes onto ships and sent them to America, but mostly because we’ve seen enough religious conflict to last us to the next millennium. Admitting you are an atheist in the UK will be just a passing comment, and not some ‘coming out of the closet’ moment.

So, I thought I’d gather a few facts on the behaviour of atheists and religious people, for comparison.

Number of each group in prison in 1997

The Federal Bureau of Prisons statistics on religious affiliations of inmates.  The following are total number of inmates per religion category:

Response               Number        %
—————————-  ——–
Catholic                29267  39.164%

Total In Prisons               96968

Compare this to the numbers of godless heathens in the population at large, about 10% in 1997…

Currently about 51% are Protestants, 24% Catholic,3.3% Christian ‘other’, 0.8% Muslim.

This works out as atheists being about 50 times less likely to commit an imprisonable offence.

Catholics are about 2/3 more likely than average to be criminals. Protestants are a less likely (about 2/3 as criminal as average).

Muslims are about nine times more likely to be in prison.

The high number of muslims is reputed to be because of the high conversion rate in black males in prison. However, the UK is over-represented by Muslims too, 12% of the prisoners, 3.1% of the population. This might be to a lot of them being poor immigrants, but a Dutch study showed that they commited more crime even weighting for socio-economic status.

So, do atheists condone the use of torture? Apparently not.

According to a survey posted on the National Catholic Reporter, here are the percentages of people who say that torture is never justified:

26% Catholics
31% White Protestant
31% White evangelical
41% Secular
32% Overall Population
Here are the numbers who think that torture is often justified:

21% Catholics
15% White Protestant
13% White evangelical
10% Secular
15% Overall Population

I have to say, Catholics aren’t coming across well here.

So, are religious morals more likely to help you to keep your marriage together?

Religion % have been divorced

Jews 30%
Born-again Christians 27%
Other Christians 24%
Atheists, Agnostics 21%

Or do religious ideals compel you to do more charitable work? Nope, atheist doctors do more charity work too. Possibly it’s because the Catholic doctors have bigger families to feed.

Researchers from the University of Chicago and Yale New Haven Hospital report that 31 percent of physicians who were more religious—as measured by “intrinsic religiosity” as well as frequency of attendance at religious services—practiced among the underserved, compared to 35 percent of physicians who described their religion as atheist, agnostic or none.

The news gets worse for the religious. It seems, the higher your IQ, the less likely you are to believe in God.

This isn’t exactly shocking news, it’s been pretty well hammered out in various psychology papers before. A decent quote for this article is that..

A survey of Royal Society fellows found that only 3.3 per cent believed in God – at a time when 68.5 per cent of the general UK population described themselves as believers.

A separate poll in the 90s found only seven per cent of members of the American National Academy of Sciences believed in God.

When the British say ‘believers’, it usually means ‘the kids are christened and we go to the midnight mass at Christmas’. The actual number of churchgoing Brits is… well, I don’t personally know any. About 3%, so I’m told.

So how religious are Europeans? Lets look at the religiosity of Europe… the darker the purple, the more they pray.

You have to remember that ‘being religious’ in Europe is generally a less ‘go to church/smite the heathens’ and more ‘get the kids into that nice church school’. One of the more amusing factoids I came across was that Catholic Italy has the lowest birthrate in Europe, 1.1 child per woman. So I take their protestations of good Catholicism with a grain of salt. You could hardly say the ungodliness and anarchy go hand in hand from comparing the least religious states with the most. Norway, Sweden and Holland are renowned for their kindly social systems and law abiding citizens. Switzerland is one of the dullest-I mean, tidy and law abiding, places on the planet. But a belief in god seems pretty uncommon there. Another example of an atheist country renowned for its law abiding citizens is Japan.

So, does atheism lead to irresponsible sexual behaviour in children? Now, that is harder to examine. Lets look at the teenage pregnancy rates of these countries compared to America (all developed countries with a high GDP).

From.. Differences in Teenage Pregnancy Rates Among Five Developed Countries: The Roles of Sexual Activity and Contraceptive Use

Adolescent childbearing is more common in the United States (22% of women reported having had a child before age 20) than in Great Britain (15%), Canada (11%), France (6%) and Sweden (4%); differences are even greater for births to younger teenagers. A lower proportion of teenage pregnancies are resolved through abortion in the United States than in the other countries; however, because of their high pregnancy rate, U.S. teenagers have the highest abortion rate. The age of sexual debut varies little across countries, yet American teenagers are the most likely to have multiple partners. A greater proportion of U.S. women reported no contraceptive use at either first or recent intercourse (25% and 20%, respectively) than reported nonuse in France (11% and 12%, respectively), Great Britain (21% and 4%, respectively) and Sweden (22% and 7%, respectively).

Since America is by far the most religious of these developed countries, it can’t be said religion is any kind of factor in stopping the children getting up to mischief. It actually seems that the less religious a country, the less irresponsible underage sex you get. Probably because of realistic contraceptive education programs.

Another common charge is that ‘all modern morality is derived from religion’, and that we are living by some ancient god’s moral code, even if we don’t accept it. Well, since I’ve seen altruistic behaviour in house-pets I’m fairly sure have never read the bible, I can declare that ridiculous. Religious morality is derived from humans own natural behaviour, not vice versa.

So, in summary, the less religious you are, the more… law abiding, intelligent, monogamous, charitable, moral and sexual responsible you are likely to be.

Obviously, a threat to civilisation as we know it.

Apparently, Dr Watson didn’t actually apologise…

So, it turns out that contrary to the press reports, Dr James Watson didn’t actually apologise for the ‘Africans have lower IQ’s’ remark. He made a very neutral statement about it, that you had to read carefully to understand.

“Science is no stranger to controversy. The pursuit of discovery, of knowledge, is often uncomfortable and disconcerting. I have never been one to shy away from stating what I believe to be the truth, however difficult it might prove to be. This has, at times, got me in hot water.

Rarely more so than right now, where I find myself at the centre of a storm of criticism. I can understand much of this reaction. For if I said what I was quoted as saying, then I can only admit that I am bewildered by it. To those who have drawn the inference from my words that Africa, as a continent, is somehow genetically inferior, I can only apologise unreservedly. That is not what I meant. More importantly from my point of view, there is no scientific basis for such a belief.

I have always fiercely defended the position that we should base our view of the world on the state of our knowledge, on fact, and not on what we would like it to be. This is why genetics is so important. For it will lead us to answers to many of the big and difficult questions that have troubled people for hundreds, if not thousands, of years.

But those answers may not be easy, for, as I know all too well, genetics can be cruel. My own son may be one of its victims. Warm and perceptive at the age of 37, Rufus cannot lead an independent life because of schizophrenia, lacking the ability to engage in day-to-day activities. For all too long, my wife Ruth and I hoped that what Rufus needed was an appropriate challenge on which to focus. But as he passed into adolescence, I feared the origin of his diminished life lay in his genes. It was this realisation that led me to help to bring the human genome project into existence.

In doing so, I knew that many new moral dilemmas would arise as a consequence and would early on establish the ethical, legal and societal components of the genome project. Since 1978, when a pail of water was dumped over my Harvard friend E O Wilson for saying that genes influence human behaviour, the assault against human behavioural genetics by wishful thinking has remained vigorous.

But irrationality must soon recede. It will soon be possible to read individual genetic messages at costs which will not bankrupt our health systems. In so doing, I hope we see whether changes in DNA sequence, not environmental influences, result in behaviour differences. Finally, we should be able to establish the relative importance of nature as opposed to nurture.

One in three people looking for a job in temporary employment bureaux in Los Angeles is a psychopath or a sociopath. Is this a consequence of their environment or their genetic components? DNA sequencing should give us the answer. The thought that some people are innately wicked disturbs me. But science is not here to make us feel good. It is to answer questions in the service of knowledge and greater understanding.

In finding out the extent to which genes influence moral behaviour, we shall also be able to understand how genes influence intellectual capacities. Right now, at my institute in the US we are working on gene-caused failures in brain development that frequently lead to autism and schizophrenia. We may also find that differences in these respective brain development genes also lead to differences in our abilities to carry out different mental tasks.

In some cases, how these genes function may help us to understand variations in IQ, or why some people excel at poetry but are terrible at mathematics. All too often people with high mathematical abilities have autistic traits. The same gene that gives some people such great mathematical abilities may also lead to autistic behaviour. This is why, in studying autism and schizophrenia, we believe that we shall come very close to a better understanding of intelligence and, therefore, of the differences in intelligence.

We do not yet adequately understand the way in which the different environments in the world have selected over time the genes which determine our capacity to do different things. The overwhelming desire of society today is to assume that equal powers of reason are a universal heritage of humanity. It may well be. But simply wanting this to be the case is not enough. This is not science.

To question this is not to give in to racism. This is not a discussion about superiority or inferiority, it is about seeking to understand differences, about why some of us are great musicians and others great engineers. It is very likely that at least some 10 to 15 years will pass before we get an adequate understanding for the relative importance of nature versus nurture in the achievement of important human objectives. Until then, we as scientists, wherever we wish to place ourselves in this great debate, should take care in claiming what are unarguable truths without the support of evidence.”

Good on him for standing his ground. There were a lot of very misleading press reports at the time deriding the man for saying what is commonly known to psychologists interested in intelligence. The only part of the ‘Africans have lower IQ’s’ that is under debate is why they do, not if they do. 

There’s a very long, but thorough, defence of James Watson’s stance and the science involved here. When the press laid into him it was extremely careful not to deal with any of the science involved, as quite frankly, it becomes obvious very quickly that there is a recognised IQ gap, admitted to even by very pro-equality ‘no race’ believers. And it’s been constant at about 15 points since testing began. There was a statement signed by most of America’s top psychologists to confirm it a few years ago. The current debate is whether it is nature or nurture induced, and it’s not going well for the nurture side,  in spite of their frantic claims to the contrary. They are also very careful to only look at the issue from a ‘white oppressing black’ angle, when it’s the Ashkenazi Jews and Mongoloid populations that consistently do best.

There is definitely the issue of malnutrition, poor health care and poor education in Africa. These will take down IQ scores. But, there are conditions just as poor in other parts of the world, and the IQ is significantly higher. You would essentially have to believe that the living standards and education of the average black American were worse than those in Suriname and rural India. Their average height and weight are the same as white Americans, so raging malnutrition can’t be the issue.

The other thing that puzzles me, is why would ‘racist white scientists’ consistently put Mongoloid peoples at the top of the IQ score rankings? The Chinese have lower living standards than the UK, but a higher average IQ. To most Brits this isn’t a shocking concept, as we’ve always maintained they were fiendishly clever. I’ve asked a few friends and no-one seems the slightest bit put out that the East Asians are smarter than us. This whole argument is essentially ‘you can’t say ever say white people are better than black people at anything’. It’s okay to observe that Chinese people do better than Europeans, but anything that shows black people performing or behaving worse than white people is racial victimisation, even if it’s 100% true.
