Given enough motivation, QRPs, biased reviewing and time, one can build an entire literature of studies proving anything. There’s plenty of all of these to prove left-wing ideological beliefs (and libertarian in economics). However, it is much harder to QRP large N datasets to give preferred results. So, what do large scale studies show about […]

We have a new big paper out: Kirkegaard, E. O. W., & Fuerst, J. (2017). Admixture in Argentina. Mankind Quarterly, 57(4). Retrieved from mankindquarterly.org/archive/issue/57-4/4 Abstract Analyses of the relationships between cognitive ability, socioeconomic outcomes, and European ancestry were carried out at multiple levels in Argentina: individual (max. n = 5,920), district (n = 437), municipal […]

In reply to: nautil.us/issue/48/chaos/what-both-the-left-and-right-get-wrong-about-race www.geneticshumanagency.org/gha/origin-of-race-differences-in-intelligence-is-not-a-scientific-question/ There’s a new kind of ‘environmentalist’ (rather, anti-hereditarian) defense in town, or at least, one that’s not commonly seen. It goes like this: This is the first of a series of blog posts about race and intelligence. My opinions on this topic are, I think, the least popular arguments I […]

On the commentariat here, and why I don’t think I can be associated with this community, despite liking the blog. My reply, as found in the comments. Most of it seems to be just rewritten stuff from RationalWiki’s collection of inaccuracies. I repost my reply below here for prosperity, and also for those too lazy […]

Back in January, Steve Hsu did an interview with Daphne Martschenko who is a phd candidate at Cambridge in education. She’s basically doing science journalism on behavioral genetics as far as I can tell. Now there’s a new interview up. I have some comments to it because Steve was a little too nice. Bias from […]

So, I posted this: Abstract We used data from the PING study (n≈1200) to examine the relationship between cognitive ability, socioeconomic outcomes and genomic racial ancestry. We found that when genomic ancestry was not included in models, self-reported race/ethnicity (SIRE) was a useful predictor of cognitive ability/S, but when genomic ancestry was included, SIRE lost […]

Data from the OKCupid project. In light of a recent paper examining who prefers to date within their own religion, I recalled that there was a question about this in the OKCupid dataset, except that it is for race: “Would you strongly prefer to go out with someone of your own skin color / racial background?” […]

I forgot to post this blog post at the time of publication as I usually do. However, here it is. As explored in some previous posts, John Fuerst and I have spent about 1.25 years (!) producing a massive article: published version runs 119 pages; 25k words without the references; 159k characters incl. spaces. We […]

Medical researchers have noticed that some diseases differ by SIRE (self-identified race/ethnicity) groups which differ by genomic (racial) ancestry. Hence, when genomic measures became available (last 15 years or so), they measured peoples relative proportions of ancestry in mixed populations to see if the diseases would be predictable by ancestry. They were. This establishes with […]

A PDF of this paper without formatting errors can be downloaded here. Abstract I review recent findings in human behavioral genetics and their implications for selective breeding and estimation of genotypic racial differences in polygenic traits. Key words: behavioral genetics, cognitive ability, GWAS, intelligence, IQ, race, selective breeding, embryo selection, genetic engineering, educational attainment 1. […]
