Rushton vindicated again: developmental speed vs. intelligence
A few days ago, geneticist Shai Carmi posted a new study on Twitter. And then he deleted his tweet and reposted a "I disavow" version. Well, what happened is that…

Davide Piffer and I have a new study out: Piffer, D., & Kirkegaard, E. O. W. (2024). Evolutionary Trends of Polygenic Scores in European Populations From the Paleolithic to Modern…
Sasha Gusev is a statistical geneticist who spends a lot of time on Twitter. He has been attacking various behavioral genetics studies lately, thus earning some ire from people in…
Probably the most common objection to studies of polygenic scores for education/intelligence for race differences is that the polygenic scores are less valid for non-European populations. For instance, here's a…
Reporting the proportion of variance explained by some statistical model is ubiquitous. However, just like p-values, it is a misleading metric. I'll try explain why it is used, and why…
In popular discourse and the media, the debate is between those who recognize significant genetic causation in mental illnesses versus the status quo blank slate people who leave all such…
Okbay, A., Wu, Y., Wang, N., Jayashankar, H., Bennett, M., Nehzati, S. M., ... & Young, A. I. (2022). Polygenic prediction of educational attainment within and between families from genome-wide…
I 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.…
While we don't take anecdotes too seriously on this blog, here I will present a small one. If you are one of those who have purchased genetic test results from…
Counting significant hits was always a dumb way to measure progress in genomic prediction of a trait. Breeders using animals and plants never bothered with this approach and they used…
