Newspaper reports are still discussing the story about the numbers of Africans admitted to Oxbridge, but I have not seen any giving the numbers of AAA students available, or any that mention intelligence. I doubt that Admissions Officers read my blog, or indeed that they would survive in post if they were ever caught doing... Read More
The ISIR July 2017 meeting in Montreal seems a long time ago, and that feeling is entirely explicable by it being 10 months since I heard the lecture in question. I was chairing the session, which normally diminishes attention to the actual content, but this talk was the exception. It came up with a counter-intuitive... Read More

Recently, I reported that Leftist journalist-enforcers had discovered an annual academic conference on subjects like genetic racial differences in intelligence had taken place, almost clandestinely, at the prestigious University College of London for four years without the SJW mob or even the university knowing about it. The usual moral panic ensued. James Thompson, the lecturer... Read More

“This Will Not Stand”
For our Social Justice Warriors, race differences in intelligence absolutely cannot be acknowledged to be genetic. If that happens, they sense, then racial inequality in outcomes will have to be accepted as fair and their entire religion of cultural determinism, the thing that gives SJWs their power, will be discredited. This sends them into paroxysms... Read More
The concept of “cognitive capitalism” was used by Yann Boutang in 2008 (modern economies are becoming more knowledge based), but I first heard it used by Heiner Rindermann in a somewhat different sense: cognitive ability is the cause of wealth. Heiner’s earliest mention of it in the title of a paper is one which we... Read More
Is honesty the best policy? In fact, in situations where people believe they will not be caught, it appears that honesty is considered a costly strategy. Many find that cheating pays, and judicious cheating seems sensible, particularly when it is enough to obtain advantage, without it being too obvious. Crafty. Do the citizens of some... Read More
Things are moving so fast in genetic research on intelligence that one cannot take a coffee break without missing important announcements. By way of small compensation, even the biggest breakthroughs are based on previous breakthroughs, so most stories in science are about a pattern of results rather than a single paper, and that pattern eventually...

As someone who’s been following HBD for the past 10 plus years or so, I’ve simultaneously been amused and enlightened by the passionate feelings the topic often engenders. The general conceit of the HBD crowd is that they possess deep insight into a body of scientific truth opening up new avenues of understanding entirely shut... Read More

Richard Lynn is one of very few academics whose impact on their discipline is such that the field could scarcely be discussed without referring to him. In psychology, and particularly the study of intelligence, Lynn has carved out a dominant, innovative, and extraordinarily productive career spanning several decades. He remains prolific at age 87, and... Read More

All educated people know that, although Darwin’s Theory of Evolution explains intelligence differences between sub-species in all other animals, this CANNOT BE THE CASE WITH HUMANS. Psychologists can research whatever they like…BUT NOT THAT! OK? If psychologists do research human intelligence, then their conferences must be picketed or, better still, shut down. Berkeley’s Arthur Jensen... Read More
At a time when some people may be wishing to set a New Year’s resolution, after some festive eating and drinking, it is apposite to look at a recent very striking headline: 'I beat type 2 diabetes with 200-calorie drinks' It describes what is said to be a very promising treatment for the treatment of...

As readers of this blog will know, it is usually Woodley of Menie who darkens these pages with talk of genetic ruin, while James Flynn is the plucky New Zealander bringing tidings of comfort and joy about rising intelligence. Now, after my foolishly letting the two of them talk unhindered together for two hours over... Read More
It is sad to hear from Chandra Chisala that our double act will no longer be available for hire, denying us both the prospect of a lecture tour, but if this really is his last word, that is a pity, because debates generally reveal new sources of data, and although personal positions rarely change immediately,...

Deep Thought
Once upon a time in America the ruling dwarves, mostly psychologists, sociologists, academics, and suchlike riffraff, held that all people were equal in everything, that men and women were identical, as were all races, ethnic groups, and cultures. Criticizing any of this could, and did, lead to firing, ostracism, and having to suffer crowds of... Read More
As is my usual custom, I wrote to the authors whose work I had commented upon in my previous post: I asked John Protzko how long the effects of intelligence boosting interventions lasted. He said that he thought this “fadeout” effect was likely to happen somewhere between 3 and 5 years after the intervention had... Read More
Stay even longer at school?
Although it is popular for people to claim that they don’t know what intelligence is, most people show an interest in boosting their intelligence. Funny, that. These schemes come around every few years: getting babies in the womb to listen to Mozart, taking vitamins and concentration enhancing drugs, counting backwards in the N back procedure:... Read More
Test results of 550,492 individuals in 123 countries
Few subjects arouse as much ire as national IQs. Questions are asked about the cultural appropriateness of the tests, whether they have sufficient scope to assess the different talents of racial and cultural groups, the representativeness and size of the samples, and even whether those results are reported correctly. National scholastic achievements, on the other... Read More
Though she is not a psychometrician, I was reminded of Nina Simone’s song by a recent paper on identifying gifted children, which found that an IQ test was better than the standard teacher referral systems at detecting bright black and hispanic kids. Good news I thought, and yet another vindication of intelligence testing. However, before... Read More
Some immigrants don’t contribute much: locals blamed.
Commenting on the findings shown on the Government website, the Prime Minister said: “What this audit shows is there isn't anywhere to hide. That's not just for Government, it's for society as a whole. Britain has come a long way in promoting equality and opportunity but what the data we've published today shows is that... Read More
Sex differences are in the news. A male Google employee reviewed some of the literature on the topic in the context of his workplace practices, and got sacked. A book questioning the role of testosterone in sex differences, and more generally the veracity of innate biological sex differences, got the Royal Society Science Book prize,... Read More
If people were crops, where would they be best planted? Like many people, I have read some books which have led me astray. They were plausible, and although I could see errors in them, I continued reading so as to learn new things. I am willing to accept that authors can be wrong about some... Read More
In my last post “Even more genes for intelligence”, I alluded to the mysterious Hsu Boundary, and I encourage you to use this phrase as often as possible. Why should other researchers have a monopoly of jargon? The phrase should help you impress friends, and also to curtail tedious conversations with persons who have limited... Read More
Africans have finally ended Russia’s historical state-sponsored dominance in the fastest form of international checkers: blitz draughts. Jean Marc Ndjofang of Cameroon (pictured above) is the 2017 blitz world champion.
Arthur Jensen's generation of race hereditarians (Eysenck, Rushton, Shockley and perhaps even Charles Murray et al) were quite different in posture from many of their current young followers. Jensen, like most of his friends, apparently wished to be proved wrong about his genetic hypothesis of racial differences in IQ because he genuinely hoped that what... Read More
The intelligence gene hunters have been stepping up their activities, and keep coming back with more trophies. Danielle Posthuma and colleagues are at it again, studying very large samples and finding further novel genes which load on brain tissues. I hope someone somewhere is keeping track of the overall picture, perhaps in a control room... Read More
If bright people live longer, is it because of the good things that social status provides? This question may appear to be very hard to answer, because one thing leads to another, and bright people are clever enough to build themselves agreeable places in which to live. One approach is to “control” for this, on... Read More
In my last post I said: I had no idea that my thesis would receive instant support the following day in a paper which begins with a stirring paragraph, worth quoting in full: Since its discovery in 1904, hundreds of studies have replicated the finding that around 40% of the variance in people’s test scores...

The picture shows that working memory for simple repetition (Forwards Digit Span, Forward Corsi Blocks) has increased slightly over 43 years, whilst working memory for the more complicated task of items in reverse order (Backwards Digit Span, Backwards Corsi Blocks) has fallen slightly. Digit span is a bombshell of a test. Despite being very brief... Read More
The loathsome truth about psychology textbooks
I have a secret hope that one day one of my readers will write a psychology textbook, and that intelligence will be mentioned in an up-to-date and accurate manner. Years ago, when reading a new UK textbook that took an apologetic and partial view of racial differences in intelligence I planned to look at the... Read More
1.6% to 2.4%
There are two main approaches to understanding the evolution of intelligence. A) Study the differences in intelligence between genetic groups. B) Study the differences in intelligence within a genetic group. Approach A is currently not being funded, as far as I know, but please let me know if there are studies I should be commenting...

I have always assumed that the Ancients were wiser than us, but I admit that my evaluation is subject to survivor bias: the best of their thinking has been passed on to us, the mediocre rest forgotten. The Ancients were not all at the level of Socrates, they also included the dullards that killed him.... Read More
Although the Bard warned against finding the mind’s construction in the face, we are apt to try. Can facial features show us the power of the brain behind the mask? Lee et al. (2017) think so. Unlike minor Scottish nobility planning regicide, they have made their judgments using the medium of facial photographs of twins... Read More

Apologies to the reader. Perhaps I wax tedious. But the question of intelligence is both interesting to me and great fun as talking about it puts commenters in an uproar. It is like poking a wasp’s nest when you are eleven. I am a bad person. Clearing the underbrush: Obviously intelligence is largely genetic–if it... Read More
Chanda Chisala and I post about each other so often that we should be employing the same agent. Properly managed, I might finally get onto a lecture tour circuit somewhere. The Shetlands, perhaps. Below is the post to which I am referring. My reply to Chisala’s post has hardly been prompt: one source of delay,... Read More
Jim Flynn once observed that no-one was funding research into the genetics of racial differences in intelligence because they feared they would find something. Here is my psychologist’s summary of where we are as regards the genetics of intelligence in general: 10%. That is to say, by poking about in the genetic code researchers can... Read More
My first experience with Raven’s Matrices was as a psychology student. We did the test as a group, and then the Alice Heim 5 test of high grade intelligence, and finally inexpertly attempted to give each other the Wechsler test of adult intelligence. As you will have noted, the concept of intelligence and the ways... Read More
No sooner do I return from my own intelligence conference, about which more later, than I note, courtesy of another scholar, a fascinating new paper showing that 40% of the variance in IQ can be accounted for by a new measure of brain networks. This is strong stuff, so with a spinning head I tried... Read More
There is nothing like sex differences in intelligence to put you on the wrong side of half the population. The story so far is that the standard academic opinion on sex differences in intelligence is that there aren’t any, or that they are small, or that the few that exist counterbalance each other. Women are... Read More
Brain size and intelligence
Here is a very interesting paper on sex differences in brain size and intelligence, notable for linking people’s brain scans with their detailed intelligence test results. It has been accepted for publication in Intelligence. Sex differences in brain size and general intelligence (g) Dimitri van der Linden, Curtis S. Dunkel, Guy Madison Abstract Utilizing MRI...

In my last article, “Scrabble Spells Doom for the Racial Hypothesis of Intelligence,” I argued that Africans should not be able to come anywhere near dominating the games of Scrabble (both English and French) or professional checkers, as they apparently do, if their real biological intelligence was anywhere near as low as their nominal IQ...

It is a measure of the quality of British life that one of its longest running TV programs is “University Challenge”, a quiz show for university students. Yes, it has always been a minority interest, but it is a showcase of talent, an astounding example of what bright young people can get to know in... Read More
Lead poisoning reduces social mobility
There are still many people who believe that intelligence does not exist or that it cannot be measured, particularly if the summary result is given as a single figure. The argument seems to be that single figure cannot possibly represent their myriad abilities. Quite so. What are they to make of a recent finding by... Read More
Smart groups are (simply) groups of smart people.
Few things attract more attention in the business world than new ways of making groups work well. As any fool knows, groups are a pain. They argue, dither, drift off course, waste time and resources, and produce loads of rubbish. Worse, all those participants draw salaries, so treasure is wasted. Surely, bosses think, any technique... Read More
Add fertilizer and yields are boosted, up to a plateau; ignore the quality of the seed and yields slowly decline.
Everyone knows about the Flynn Effect, but very few about the Woodley Effect. When Woodley was working on his paper in 2013 “Were the Victorians cleverer than us? The decline in general intelligence estimated from a meta-analysis of the slowing of simple reaction time” I wrote to Charles Murray about his findings, and in his... Read More

It is good that people are discussing IQ. Fred Reed’s post has drawn many comments, too many for me to answer individually. Here I outline the main heads of his argument as I see them, and some of the relevant research. My summary of Reed’s post is: Intelligence is important; intelligence research is important and...

No story about the brain is simple; no one study is definitive; and it takes many years to sort out conflicting and inconsistent findings and establish a weight of evidence. It is a fundamental truth that any researcher who can put a person in a scanner can publish a paper. Any researcher able to talk... Read More
  I have never played Scrabble. I may have tried once, but certainly gave up very quickly, before even finishing the game. I like words, but I don’t particularly like games. I can’t see the point of Scrabble, and would prefer to read a book, in which the words are assembled to convey meaning. Unscrabble.... Read More
Intelligence is worth talking about because both the reality of intelligence and perceptions regarding intelligence set limits on the possible and influence policy. For example, if the population of India on average really is below borderline retardation, the country can never amount to anything. If Latino immigrants really are as stupid as white nationalists hope,... Read More
What is the use of Psychology? Surely knowing some psychology should confer an advantage? I mean a real advantage, over and above being able to give complicated post-event commentaries? How about this? If survival means avoiding premature death, then living is perpetual problem solving, and the better the solutions to problems, the better the standard... Read More
Flynn Effect background explanations.
    The Flynn Effect is important to understand; it is better understood now than ever before, but there is more to research; and it is probably more limited in its real-world consequences than people imagine, though the long-term consequences are still being debated. Say you take any test of ability, and as an example... Read More
  The Flynn Effect was originally noted by Rundquist (1936) and Lynn (1982) and then Flynn (1984). Credit should probably go to Runquist, but a happy compromise is to call it the FLynn effect, in honour of the two major researchers. The history has been described by Lynn, in part of a Special Issue on... Read More
