Mainstreamers keep making progress: educational attainment variation “likely” caused by ancestry variation in Europe

Lawson, D. J., Davies, N. M., Haworth, S., Ashraf, B., Howe, L., Crawford, A., … & Timpson, N. J. (2020). Is population structure in the genetic biobank era irrelevant, a challenge, or an opportunity?. Human genetics, 139(1), 23-41. Replicable genetic association signals have consistently been found through genome-wide association studies in recent years. The recent…

Species genetic variation and number of subspecies/races/breeds/breeding populations/clusters etc.

A straightforward research idea: Compare the recognized count of subspecies (races/breeds/breeding populations/clusters etc.) with measures of genetic variation. The most obvious is the Fst but it’s not an optimal metric. There is some literature on this: Woodley, M. A. (2010). Is Homo sapiens polytypic? Human taxonomic diversity and its implications. Medical hypotheses, 74(1), 195-201. Fuerst,…

Sesardić’s conjecture: preliminary evidence in favor

In Making sense of Heritability (2005), Sesardić wrote: On the less obvious side, a nasty campaign against H could have the unintended effect of strengthening H [hereditarianism] epistemically, and making the criticism of H look less convincing. Simply, if you happen to believe that H is true and if you also know that opponents of…

IVF tech by country: historical growth

Some time ago, I made a plot of this that Steve Hsu ended up posting. However, here’s a newer one. The public datafile is here. Latest published report is here, which reports data for 2014. They publish a paper every year, or so, which report on ~5 year old data. I see no report for…

Predicting IQ from genetics: how far have we come? [January 2020]

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 ridge regression for best predictive power (a “two cultures” problem no doubt). Researchers in human genetics are starting to catch up, implementing clever Enet approach…

New paper out: Racial and ethnic group differences in the heritability of intelligence: A systematic review and meta-analysis (Pesta et al 2020)

So, our big Scarr-Rowe meta-analysis dropped recently. I was traveling at the time, so there was a bit of a delay to this posting. I also recorded a long video covering the reasons why this kind of study is important. Pesta, B. J., Kirkegaard, E. O. W., te Nijenhuis, J., Lasker, J., & Fuerst, J….
