My impression of Damore’s Google Memo is that it is a thoughtful and well-considered personal opinion about workplace differences in abilities and attitudes. The tone is reserved, measured, and reasonable, avoiding sweeping claims. For example, it restricts its scope to the particular office in which he worked, and not Google as a whole. It is...

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

This week’s big story on the CultMarx front was the firing of Google employee James Damore. The firing offense was, he had written a document titled Google’s Ideological Echo Chamber and circulated it on Google’s internal network. The document was leaked to journalists, the nation’s CultMarxists threw a collective fit of hysteria, and Damore got... Read More
Simply because the immediate reaction to the Google Memo concentrated on sex differences I gathered together some posts on sex differences, showing that the sexes differ somewhat in their abilities: not very much, but enough to make a difference at the extremes, and it is the extremes which make a difference to technology based societies,...

Since Google does not employ me, it cannot sack me, but I admit to feeling a little left out of the news recently. In a late bid for notoriety I have put together a series of my previous statements about sex differences, and if you will kindly circulate these as widely as possible someone may... Read More
France is a territory which lies to the south of the English Channel, and was largely managed by the English Crown till it fell under the sway of the local inhabitants, with mixed results. It is a large domain, blessed with ample resources and noble prospects, of which its azure Mediterranean coast is a treasured... Read More

John Derbyshire writes: I gave a half-hour PowerPoint presentation under this title to the AmRen Conference on July 29th 2017. Video of the event will be posted at the AmRen website some time soon. As a pre-Information Age relic, my default format is the essay. For events like this, I first write out an essay,... Read More
The time has come for a review post on the laws of behavioral genetics. I will talk about why these laws are laws and why they are important. Eventually, this will be merged into my Behavioral Genetics Page, but for now, I will start with this primer. The five laws of behavioral genetics are: All... Read More
When did humans first become human? The answer is far from simple, because the question assumes that sometime in the past, humans achieved modernity and were locked within an evolutionary loophole where natural selection no longer applies. Despite the absurdity of this scenario, and in stark contrast to empirical data, it is widely believed that... 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
Here are two presentations from the London Conference on Intelligence in May. They are in what I would call the proper format, in that both the speaker and the slides are visible, and the sound is on throughout. Almost like being there. The conference is speakers only, so the audience is about 24 persons, hence... Read More
If solving problems doesn’t motivate you, what does?
One of the joys of attending a conference on intelligence, such as ISIR2017, is hearing people report the results of their detailed investigations into overblown claims in science reporting that one had oneself thought questionable. Will the proper researcher come to the same conclusions as you had in your own preliminary reactions? Years ago I... Read More
Things move fast here. No sooner do I give you the brief description of my visit to see the Big Brain than I can announce the movie of the same. Here is the Big Brain film, showing how it was put together, and what it is like to use. http://mcin-cnim.ca/research/bigbrain/ Here is the link to... Read More
As loyal readers will know, getting to conferences is an intellectual challenge for me. Having worked out where and when they are to take place, the problems multiply. Travel must be arranged for both before and after the conference dates, which is difficult when the venue is in a different time zone, and even more... 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. https://drive.google.com/open?id=0B3c4TxciNeJZTGpEdkJBbnVmNFE Unlike minor Scottish nobility planning regicide, they have made their judgments using the medium of facial photographs of...

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. http://www.unz.com/article/will-scrabble-have-the-last-word-on-the-iq-debate/ My reply to Chisala’s post has hardly been prompt: one source of... Read More
Dear Prof Posthuma, Thank you for your comments. These comments are not new, and that is not necessarily a bad thing. Actually, it works to my advantage because over the years I have had the opportunity to develop ways to rebut these criticisms. One of the ways of answering your criticisms, and the one which...

As you know, this blog moves at internet speed, not the glacial creep imposed by academic publishers, with their lucrative frustration of intellectual discourse. No sooner do I write about the work of Piffer, and his use of the new findings of Sniekers et al. (2017) than a senior author on that latter paper, Prof... Read More
Polygenic scores cannot predict a person's IQ, but can they tell a genius apart from the crowd?
A day is a long time in genetics research. Yesterday I made the following prediction about the method that David Piffer has used to estimate racial intelligence: Prediction: we will need very many more SNPs before we can attempt predictions of individual IQs across different races at better than a correlation of r=0.7 Having made...

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
Underestimated associations
It is now commonplace to denounce any observed associations between groups and behaviours as being “stereotypes” with the strong implication that these preliminary impressions are dreadfully wrong, and malevolently so. However, these first impressions should be evaluated against objective measures, in which case they can be shown to over or under estimates of the association... 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
After the slaughter of innocents, the ritual of abnegation. While parents pleaded for news about the pieces of their children, the citizens of Manchester met in a public show of solidarity, in an all faith meeting to show that “the bombers would not win”. We have plenty of experience of organizing those. Commendable, very Christian,... 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
My attitude to exercise was best summed up by cartoonist Paul Terry: However, I am not deaf to the cacophony of advisers recommending that people should keep active, particularly the over 50s. The notion seems to be that the elderly serve some undefined but useful purpose which could be prolonged by physical exertion. I find... 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...

There was a time when boys played games of marbles following strict playground rules: contestants had to stand a prescribed distance away from the little pyramid of marbles, and chuck only marbles of the prescribed size. Rules ruled. Piaget was intrigued by the explanations children gave for moral judgements, and the playground is the arena... Read More
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
Estimating blogger productivity
This is not about baseball, but about blogging, but times are hard for some columnists, so I needed to get your attention. Steve Sailer has put up his March statistics (More records for iSteve, April 3) showing that last month his posts generated 19,707 comments containing a total of 1,485,295 words. By any standards, this... 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
I can claim to have been assaulted by micro-aggressions. I find myself profoundly hurt when people in my presence say “Intelligence – whatever that is”. They do it to vex me, which is beastly of them. Other aggressive behaviours include people in conversation denouncing anyone who holds a particular political opinion, without considering that I...

The mental convolutions in which some will engage in order to ignore the evidence that the polar ice caps are melting—and if not from warming from what?—is as astounding as the convolutions and denial of basic facts that characterize those who believe the government’s official 9/11 fairy tale. If all science is rigged, as a... Read More
I am fortunate in having readers who look after me. Some have offered me refuge in their countries and their homes from what they expect otherwise will inevitably be the midnight knock on my door. Others correct my mistakes from typos to content. As I have never considered myself infallible, I carefully read what they... Read More
Earth has not anything to show more foul
As these things go, it was not too bad. One idiot in a car murdered 3 people, with 7 more in a critical condition who may die, at least 40 with terrible injuries, and many more people traumatized. Crowds of tourists ran away from the place of slaughter at Westminster Bridge. Earth has not anything... Read More

Saturday is a relative slow day in my household, so it felt somewhat of a rebuke to read on the BBC that the Tsimané people have an ideal lifestyle, walking some 17,000 steps a day, as compared to the lethargic wealthy West, who aim for 10,000 daily steps but rarely take them. http://www.bbc.co.uk/news/health-39292389 Those of...

Despite being interested in intelligence, I am also on guard against judging the mind from the face (there's no art to find the mind's construction in the face) while probably doing just that all the time. I assume that I judge mental ability by conversations which go beyond pleasantries. Indeed, perhaps measuring how quickly people... Read More
blade-runner
Blade Runner had an impact on me, both as a film and because it was an introduction to the writings of Philip K Dick, whose whimsical work was based on wondering what it meant to be human. Are we as individuals merely constructions of fundamental genetic coding mechanisms, which create treasured but probably false memories... 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
Personally, after reading the above description, I have Linda in my mind’s eye, and I can just see her lecturing me on what sort of yoghurt I should eat. If I ever met her, I would not dream of admitting that I drive a diesel car, and that I have very recently taken up sketching... 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
Throughout my American Nations series (based on the books American Nations: A History of the Eleven Rival Regional Cultures of North America by Colin Woodard and Albion's Seed: Four British Folkways in America by David Hackett Fischer) I've talked about how North America is divided into distinct ethnocultural regions based on historic settlement patterns. These... 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
In my earlier entry (Clannishness – The Series: How It Happened), we saw that the thing that made the difference between WEIRD Northwestern Europeans and their more clannish neighbors was the selective pressures that each underwent during their histories – particularly since the fall of Rome until the present. This era in time established the... 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
