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
The Oval Office tape of Richard Nixon and Pat Moynihan posted on YouTube and recently noted by Steve Sailer has both men saying that they know the truth about IQ and race–but can never admit it. And look what happened as a result.’s position: the truth shall set us free. Moynihan had sent Nixon... 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
How can a heretic safely and openly discuss taboo topics? Not easy, particularly on today’s intolerant university campuses, but history shows multiple tactics to overcome censorship. It’s just a question of being creative and knowing the limits. Familiar examples have included using non-human parables—think Animal Farm— substituting the neutral sounding euphemisms such as “at-risk youngster”... 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
The Six-Percent Solution
I have gotten many hundreds of emails–OK, three emails, but I am rounding up–asking me whether there is a super-race. There are different views on this matter, discussion being carried on with the manners of a hockey match. For people who have better things to do than study abnormal psychology, the players are briefly as... 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
I am still settling in at so please forgive me if I forget my lines and bump into the furniture, because the stage is much larger than my former small theatre. Not only that, but the cast is enormous, and the commentating audience ten times larger than usual, and rowdier. No country for an... Read More
Things move fast. A published paper comes to the attention of Steve Sailer and suddenly a section of a puzzle gets completed. Better still, the boundaries of ignorance get pushed backwards, which is always a good idea, and a fine Christmas present. From the isolation of my study, and from the depths of my... Read More
Why the Future is Looking Bright for Dullards
David H. Freedman’s “The War on Stupid People” (The Atlantic) provides a compelling argument that we collectively assign great weight to the trappings of intelligence. Academic credentials, standardized test scores, a professed interest in technology, and even the right kind of physical appearance (glasses, not too athletic) all serve as easily recognizable markers of intelligence,...

For months the business headlines of America's leading media outlets have been charting the looming downfall of Viacom CEO Philippe Dauman, now on the verge of losing control of his enormous media company to Shari Redstone, the once-estranged daughter of controlling shareholder Sumner Redstone. Just a few years ago, he was America's highest-paid chief executive,... Read More
A few days ago I received an email from Mike Berman, a good friend and Dissident Right supporter. I reproduce it here with Mike’s permission. The precise statement of that is in Chapter 13 of The Bell Curve: “It seems highly likely to us that both genes and the environment have something to do with... Read More
Chanda Chisala has been producing pile after pile of nonsense for quite some time. At first, I was content with simply leaving comments at his posts refuting his rubbish because it was rather easy to point out where he was full of baloney. Since then, I've been banned by him, mostly for my signature flair.... Read More
SCRABBLE World Champion (2015), Wellington Jighere, of Nigeria (on the left!).
Thomas Sowell vs. Richard Lynn
I will now respond to some hereditarian scholars who wrote some articles in response to my data and arguments on the Black-White IQ Gap (Fuerst, Frost and Thompson). I hope to cover every valid concern brought up so far, including technical issues on data reliability, etc. I will also address some of the alternative explanations... Read More
Some really interesting and quite significant publications have appeared in recent days. Each adds key pieces of evidence to the topic of HBD, and I wanted to talk about each here. I may do review columns like this periodically, somewhat akin to HBD Chick's (get well soon!) linkfests. This is nothing short of a brilliant... Read More
(Please see also link to older post at the bottom of this one.) Donald Trump:  Elon Musk: Mitt Romney:   Previously: Idiocracy Can Wait?
What does it take to make a nation great? What makes a country a great place to live, a healthy society, and a bastion of stability? Various theories and ideas have been put forward, and I think they are all pretty much bunk. I think we can apply a little reductionism here, and conclude that... Read More

There has been much talk here about Chanda Chisala's article "The IQ gap is no longer a black and white issue." Much of the article focuses on the Igbo (known also as Ibo), a people who live in the Niger Delta and "are well known to be high academic achievers within Nigeria." In the United... Read More
The fact that black immigrants to the United States have shown achievements that are superior to native black Americans has been a phenomenon studied since at least the 1970's. At first it was just the Caribbean blacks who were a subject of this unexpected outcome. As black Africans kept immigrating into the US, they showed... Read More
Post updated, 7/23/15. See below! At long last, I reach my 200th blog post. It's been a quite a ride! Blogging on human biodiversity – or simply humanity – has taught me a great deal. Since the start, I hoped that I could offer some meager contribution to mankind with this blog. I will continue... Read More
One of the greatest pieces of evidence demonstrating that the family/rearing environment has no effect on eventual outcomes is the absence of birth order effects. Birth order is an excellent test for these effects: it is something that systematically differs between siblings and is bona fide non-genetic (mostly). Hence, it's a great way to see... Read More

Great at reading or recognizing faces? You might not do so well on an IQ test.
The English psychologist Charles Spearman was the first to argue that a single factor, called "g," explains most of the variability in human intelligence. When observing the performance of children at school, he noticed that a child who did well in math would also do well in geography or Latin. There seemed to be a... Read More
Post updated, 10/21/14. See below! It's general trope in the HBD community: people are getting dumber. The low IQ are outbreeding the high IQ, leading to a slow decline in genetic intellectual potential in the population. Indeed, my own analyses seem to have shown that there was a fair fertility advantage among the lower IQ... Read More
My weekly posts are now appearing on The Unz Review( By accepting Ron's invitation, I hope to reach a bigger audience and bring myself closer to other writers in the area of human biodiversity. When people work together, or simply alongside each other, minor differences can be ironed out and major differences narrowed or at... Read More
Can be quite substantial. Jump off the Empire State Building and see for yourself. But, beyond that, the question remains how much of the variation in health outcomes and longevity can be explained by behavioral variation? Well, we don't quite know. But we do have evidence which indicates that – at least in the developed... Read More
Here’s a wee brainteaser for you to while away ninety minutes with. That is one of the six problems set in this year’s International Math Olympiad (IMO), just held in Cape Town, South Africa from July 3rd to 13th. You can download all six problems in the language of your choice, fromAfrikaans to Vietnamese, here.... Read More
We Had a Good Run
In this column I will explain why the Caucasian race will shortly be extinct, and why it is a good idea. This conclusion flows ineluctably from evolutionary considerations and studies of racial IQ. It is simple biology.   The Evolutionary-IQ Perspective As Race Realists have argued at length, IQ is a reliable measure of intelligence,... Read More
Gray Matter in a Brown Package
Latinos are now seventeen percent of the population, and the president is doing everything he can to increase that proportion. Will they assimiliate successfully? There are many reasons for suspecting that they will not, and others for suspecting that they will. A crucial sub-question is whether they are as intelligent as whites. Many quietly think...

Does the relatively muted reaction to Nicholas Wade’s recent A Troublesome Inheritance mean that the Political Correctness Ice Age is receding—and that we might even have another interglacial, like thebrief period in the 1990s which saw the publication of books like Jared Taylor’s Paved With Good Intentions, Charles Murray and Richard Herrnstein’s The Bell Curve...

My previous post – “Squid Ink” – has spawned a little discussion about the role of the "environment." However, I'd argue what all the discussion is about – what it is always ever about when people invoke "environment" – is changeability. This is what people really want to know about that, and they see heredity... Read More
A steady increase in reaction time seems to begin circa 1980 in Sweden, Great Britain, and the United States (h/t to hbd* chick) Has reaction time been steadily increasing from generation to generation? This was the finding of a paper last year, which argued that mean IQ had fallen in Britain by 13 points since... Read More
Allele dominance (source). A single copy of a dominant allele is as effective as two copies of a recessive allele. The current thinking is that intellectual capacity has increased in humans through new alleles that cause small positive effects at a large number of gene loci. It now seems that some of these new alleles... Read More
Post updated, 9/14/14 6/5/14. See below! In my earlier post on Gregory Clark's work, The Son Becomes The Father, I laid bare the case for the known high heritability of human behavioral traits (including values and attitudes) and life outcomes. As well, equally important, I illustrated the complete absence of shared environment influences on these... Read More
said! I spotted it in a conversation with Dennis Mangan. I guess it's good to see that someone else has brought up these points. Here's the rest of the it seems, Dennis Mangan – like many in the medical establishment – appears permanently locked into a rather unscientific way of thinking. The problem of disentangling...

World distribution of the recent Microcephalin allele. The prevalence is indicated in black and the letter 'D' refers to the 'derived' or recent allele(Evans et al., 2005) Almost a decade ago, there was much interest in a finding that a gene involved in brain growth, Microcephalin, continued to evolve after modern humans had begun to...

A vigorous discussion has been triggered by the release of Gregory Clark's The Son Also Rises: Surnames and the History of Social Mobility. In this book, Clark details his work which shows a large transmission of status from generation to generation, all across the world, going back centuries. The discussion has raged on the mode...

"Misdreavus" was having a field day on Twitter yesterday. Here are some the products of that: For the record, "misdreavus" is non-White, like me. He is also the coup de grâce about that? These are basically the running themes on my blog, and other places in the HBD-space. As we've seen with "misdreavus's" commentary previously... Read More
I may have to make "misdreavus" a co-blogger here at some point, considering how I quote him here. But, in defending HBD (Human BioDiversity), he has made a nice basic summary of the reasons why we believe in HBD (that is, overwhelming evidence). This was all in response to social anthropology scholar A. J. West,... Read More
PISA test documents at a German school (source: Theo Müller). PISA and IQ tests are informing us about differences in intellectual capacity by country. Meanwhile, genetic studies are informing us about genomic differences by country. Davide Piffer has been tapping into these two pools of data to explore the links between genes and intellectual capacity.... Read More
