Recently I got a private question from anon: A quick question if you don’t mind: how come Blacks from sub-Saharan Africa have an average IQ of 70, which is even lower than that for Blacks from the United States (85)? Shouldn’t it be the case that both of these groups have a similar IQ? After…
Continue ReadingLast year, this meme was floating around: The data are real enough, and the years are right. It seems that Franco was able to sustain fertility in Spain during his regime. Is he the only one? Well, his neighbor, Portugal, also had a dictator of sorts, Salazar, who was in power 1932-1968. How does their…
Continue ReadingI keep getting asked about this, so I figure a short note is in order. Some months ago, Commie Kevin (Twitter) AKA. Kevin Bird published an anti-hereditarian study: Bird, K. A. (2021). No support for the hereditarian hypothesis of the Black–White achievement gap using polygenic scores and tests for divergent selection. American Journal of Physical…

The Negative Religiousness-IQ Nexus is a Jensen Effect on Individual-Level Data: A Refutation of Dutton et al.’s ‘The Myth of the Stupid Believer’. Journal of Religion and Health, 1-23.

Continue ReadingMany people are aware that American universities practice something called affirmative action. Really, this just means a kind of reverse racism that was instituted during the 1960s cultural takeover (or glorious revolution, depending on your view). It consists of providing easier access to universities, and sometimes jobs, based on your sex and race. Easier as…
Continue ReadingIn 2012, Ron Unz (of Unz.com) wrote a long article with the title Race, IQ, and Wealth published in The American Conservative (follow-up also in 2012 Race/IQ: Irish IQ & Chinese IQ). Unz did not shy away from the central race and intelligence debate. In fact, he relied on data from the 2002 book by…
Continue ReadingBook review of The Genetic Lottery: Why DNA Matters for Social Equality by Kathryn Paige Harden. Most people know about the top woke biologists of the past. I am of course thinking here of Richard Lewontin (evolutionary biologist mainly population genetics) now known primarily for his Marxism and fallacy about classification, and Steven Jay Gould…
Continue ReadingBack in October Razib Khan had Carole Hooven on his podcast. She’s the author of a new popsci book on testosterone: T: The Story of Testosterone, the Hormone that Dominates and Divides Us (342 pages). In the book she mentions some other recent woke books on testosterone, specifically: Testosterone: An Unauthorized Biography (288 pages) by…
Continue ReadingA reader sent me this interesting report that I had previously somehow not heard of: Rune Jørgen Sørensen, Jon Marius Iversen, Johan From, and Hans Bonesrønning. Culture and school performance: Evidence from second-generation immigrants in Norway. 2015-2020 The paper studies how the cultural orientation of immigrant parents affects the school performance of their children. We…
Continue ReadingThis mistake is very common, and here we look at an arbitrary example I was sent promoted by Rob Henderson on Twitter. This error is quite common (first example I found), so this was not chosen to say Rob is particularly bad at this. The same error can often be found in discussion of The…
