When the results of PISA 2018 were unveiled, there was significant skepticism about the much improved results from Sweden, based on the unimpressive coverage ratio (86%, vs. 99% in Germany) and large share of pupils excluded on account of being "new arrivals" (11%, vs. 0.4% in Germany) Expressen reports: Sweden's PISA success is based on...

Map of Spanish PISA results via /u/bulfcc on Reddit: As usual, clear N-S gradient, if not as steep as in Italy. Incidentally, the north is in demographic free-fall (2x deaths as births), while the south is stable (births~=deaths). Here's the data from 2018: Not good, but a predictable pattern. *** Thanks to another Twitter user... Read More
Sugonyaev, Konstantin, and Andrei Grigoriev. 2019. “Эффект Флинна в России.” Экспериментальная Психология 12 (4): 50–61.

The PISA 2018 report has detailed regional data for Canada, Spain, and Kazakhstan (as well as more limited regional data for eight other countries), which you can find on pp.255-260 of PISA 2018 Results (Volume I) [excel]. We have already had maps of regional PISA-based IQ in Italy, Spain, Russia, and Germany, but this is... Read More

"Intelligence researcher" doesn't exactly have a reputation as a safe, uncontroversial profession. There are perhaps 200 people in the world who do that full-time. Despite this small population, we seem to get a story - often multiple stories - of them getting denounced, defamed, deplatformed, threatened, and even physically attacked every single year. Thanks to... Read More
Yoder, Christian N., and Scott A. Reid. 2019. “The Quality of Online Knowledge Sharing Signals General Intelligence.” Personality and Individual Differences 148 (October): 90–94. Humans don't work for free. Gold. USD. Online reputation. There needs to at least be something, because otherwise there will be nothing.

Steve Sailer has just posted Michael Woodley of Menie's lecture (hosted on Edward Dutton's YouTube) on the cognitive archeogenetics of ancient and modern Greeks at this year's Psychology Conference. Explaining the cultural/intellectual decline of Classical Greece is one of the major puzzles of history. One HBD-realistic approach is to approach it from the point of... Read More
Climate scientists and IQ researchers are both (largely) correct. Both of the sciences that they represent are hugely important for understanding the future, while both also have tribal ideological detractors on the right and left, respectively. Though this wasn't always so. For instance, Svante Arrhenius, the man who constructed the world's first climate model back... Read More

Robin Hanson once wrote a blog post about how reasonably intelligent people (for instance, the sort of people who read his blog) tend to overestimate how smart everyone else is. For instance, about half of Americans are unable to correctly read a table and do a simple addition/subtraction calculation: Such is the banal reality of... Read More
The FLynn Effect has not acted uniformly across the various domains of intelligence. To put it very roughly, in the past century, the developed world has seen a two S.D. improvement on Raven's Progressive Matrices, hardly any improvement in verbal or Backward Digit Span tests, and a one S.D. improvement in various picture arrangement and...

From a new paper by Mingrui Wang and Richard Lynn: It seems that rural Chinese teens in 2006 were already as bright as their urban counterparts in 1988. This is comparable to increases in South Korea between 1970 and 1990. Note that Raven's tests see some of the biggest increases due to the Flynn Effect,... Read More
Mankind’s IQ is 84-88. Becker May 2018 update. Belorussia has long been a blank spot on the world IQ maps (and when it was not so, its results were based on the average of Ukraine, Russia, and Lithuania's scores). However, in David Becker's latest world IQ update, there finally appeared a concrete estimate of Belorussian... Read More
Georgia makes basically no sense from an HBD perspective. Georgians aren't very bright, and GDP growth has been unimpressive For all the praise heaped upon Georgia by deregulation advocates and libertarians, its institutional miracle hasn't been accompanied by an economic one; GDP per capita is only about 15% above peak Soviet levels. This is much... Read More

While data from various IQ tests are useful for global scale analyses (e.g. GDPcc correlations), they are far less reliable for particular countries. That's why I'm a big fan of the OECD's PISA assessments, which are highly standardized, have large samples from similar age groups, take place concurrently once every three years, test those aspects...

Results of PIRLS 2016 (4th Graders) have just come out (h/t Polish Perspective).

The Franco-German media organization Arte recently produced a documentary about the decline of global average IQ. What courage in the Current Year! What resolve! Not only do they treat IQ as a legitimate concept, but are even willing to seriously contemplate whether it is declining, and what could be done about it. Could the tide... Read More
Just came back from a workshop on "Intelligence and Culture as Factors of National Competitiveness" organized by the Institute of Psychology RAS. The most interesting presentation was by Konstantin Sugonyev, which may be published in a forthcoming paper. It concerned the following test: This is a test on the Russian Defense Ministry's website, where potential... Read More
I posted about German regional academic performance back in 2016. The evidence seemed to indicate that German IQ was fairly uniform across Germany, once you took the immigrants out. However, soon afterwards I got the following curious email from one Carolin: You can read the report here (I can't read German so you'll have to... Read More
David A. Hardy This week I was mainly occupied with writing a massive (6,300 words) overview of the history of IQ testing in Russia and what we currently know about the geography of Russian intelligence.

Surviving political repressions in Communist regimes is one of those rare problems that don't seem to be at all g loaded. When someone like spandrell talks of "IQ shredders" he refers to the role of modern cities as fertility vortices for society's best and brightest. But in the 20th century those shredders could be all... Read More

From Turkey's PISA 2015 National Report: In 2015, Richard Lynn and coauthors did one of their standard national IQ analyses on Turkey (based on the results of PISA 2012). Summary: There are seven points of interest in the results. First, the total PISA scores adopted as IQs were significantly positively correlated with per capita income... Read More
Via Stuart Ritchie: This looks about right. Opinions on the validity of g seem to mostly correlate with your position on the economic part of left-right spectrum. This explains why academia is so allergic towards it, while the otherwise SJW-wy but libertarian-heavy, autistic, and high-IQ rationalist/futurist crowd takes such an unexpectedly close interest in it....

Now that we have established that immigration is not much good, let's take a look at another component undergirding our transition to Idiocracy - the differential fertility rates of different IQ groups. This is a highly contentious topic, and not just on account of the usual political kurfuffles, but also on real disagreements as to... Read More

HBD, Hive Minds, and H+
Today is the publication date of Hive Mind, a book by economist Garett Jones on the intimate relationship between average national IQs and national success, first and foremost in the field of economics. I do intend to read and review it ASAP, but first some preliminary comments. This is a topic I have been writing... Read More

Chanda Chisala's article on black/white IQ differences has been making quite the stir in the HBDsphere. It is well worth reading in its entirety, as some of the points he makes - e.g., the evidence for high IQ amongst certain African ethnic groups such as the Igbo - are quite compelling and novel even to... Read More
Why is the HBDsphere so damn interested in IQ, anyway? While I can't speak for the "movement" at large, in my own case the interest stems from the fact that it explains so much about our world. (In fact, I was interested in this topic long before I discovered HBD, Charles Murray, Jensen, Lynn, Rushton,... Read More

This conference is organized by brain health and IQ researcher Hank Pellissier, and its aim is to bring all kinds of quirky and visionary folks - "Biohackers, Neuro-Optimists, Extreme Futurists, Philosophers, Immortalist Artists, Steal-the-Singularitarians" - together in one place and have them give speeches and interact with each other and the interested public. One of... Read More
This Sunday I had the pleasure of meeting up with Hank Pellissier, who used to work for the IEET, a futurist/transhumanist institute, and is now a blogger-journalist and amateur researcher at the Brighter Brains blog. As one may glean from the title of that blog, his current area of major interest lies in IQ and... Read More
Further to my post on the remarkable failure of Scandinavian education systems to develop their students to anywhere near the levels indicated by their IQ potentials, a professor of mathematics at a Wisconsin university sent me data on the percentage of respondents in the TIMSS who gave the correct answer to the following question: Below...

I had been meaning to post about this for a long time. Better late than never, I suppose.The TIMSS and PIRLS are international assessments of academic ability in math, science and literacy that are conducted once every four years. They are similar to the PISA tests, although the latter are less purely academically focused and... Read More

In one of the recent posts on corruption, commentator AP wrote: Is this true?

Regular readers of this blog may remember my comments regarding Ron Unz's theory that East Asians have high IQ's independent of time/nutrition/urbanization whatever it is that causes the Flynn Effect.

About Anatoly Karlin

I am a blogger, thinker, and businessman in the SF Bay Area. I’m originally from Russia, spent many years in Britain, and studied at U.C. Berkeley.

One of my tenets is that ideologies tend to suck. As such, I hesitate about attaching labels to myself. That said, if it’s really necessary, I suppose “liberal-conservative neoreactionary” would be close enough.

Though I consider myself part of the Orthodox Church, my philosophy and spiritual views are more influenced by digital physics, Gnosticism, and Russian cosmism than anything specifically Judeo-Christian.
