      Considering Charles Murray's new book comes out tomorrow it's good timing that this little side-project I took on (in the middle of my comprehsensive exams!) just came out.https://osf.io/preprints/socarxiv/2qfkt/ …

      I'm annoyed this paper needed to be written. This debate just won't die, no matter how poor the proclaimed evidence is. I suspect this is because there's a concerted effort to maintain the debate in popular discourse. See: https://kevinabird.github.io/2019/12/18/The-Genetic-Hypothesis-and-Scientific-Racism.html …

      Here's a brief summary: Hereditarians make two major claims about Black and white IQ gap. 1. The gap in intelligence and educational attainment we see is substantially caused by genetic differences and 2. These genetic differences are the result of natural selection.

      Historically these arguments have relied on indirect evidence based on heritability estimates (criticized here http://www.acteon.webs.upv.es/ARTICULOS/KEMPTHORNE-LOGICAL_EPISTEM-_1978-_BIOMETRICS.pdf …) life-history theory (criticized here http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.731.3826&rep=rep1&type=pdf …) or comparing national IQ scores (criticized here http://emilkirkegaard.dk/en/wp-content/uploads/Why-national-IQs-do-not-support-evolutionary-theories-of-intelligence.pdf …)

      Recently, however, the wealth of genome-wide association studies led to some determined (and inexperienced) race scientists to use SNPs associated with educational attainment to prove genes caused the racial achievement gap. They got results like this and rejoicedpic.twitter.com/YcgfP0bYP2

      Unfortunately for them, we quickly found out you can't just compare SNP frequencies between populations because systematic biases are introduced based on what population in which the SNPs were identified. (see https://www.nature.com/articles/s41467-019-11112-0 …)pic.twitter.com/7tNtkbCbL1

      These biases have been shown to cause false signals of selection, even in traits we have spent a lot of time studying, like height (see https://elifesciences.org/articles/39725  & https://elifesciences.org/articles/39702 ) one solution is to use less biased effect sizes based on within-family studies.

      These concerns were not taken into account by the people who wanted to show black people were genetically less intelligent, so I took it upon myself to show the results they found were caused not by actual evolutionary patterns but by systematic biases in GWAS data.

      I used two approaches: first I compared the difference in polygenic scores of African & European populations from the 1000 genomes project to 10000 comparable randomly generated polygenic scores. When this method is applied to skin pigmentation it looks like thispic.twitter.com/GOfODnMzHS

      When I used this method from the a GWAS on educational attainment using between family effect sizes I saw signals of divergent selection, like hereditarians claim, but when I used within-family effect sizes the signal completely disappearedpic.twitter.com/g2ob1tGIsQ

          Next I used the method from https://www.nature.com/articles/s41467-018-04191-y … which compares genetic differentiation of populations (measured as Fst) between SNPs associated with a trait and 10,000 sets of SNPs not associated with a trait but similar in other aspects. Here's what SNPs height looks likepic.twitter.com/BO9hzW1oq2

          When I used the GWAS results from an educational attainment and cognitive ability study I found this pattern which is not suggestive of natural selection. It also shows that SNPs related to these traits are not very different in frequency between Africans and Europeanpic.twitter.com/7U3jTcovhE

          One thing I can do with that knowledge is compare how much genes related cognitive ability vary between groups & how much IQ varies between groups. Using national IQ data sets from hereditarians, I find that <15% of variation in IQ scores can be explained by genetic variation.

          Using the most reliable methods right now I show no signs of divergent natural selection acting on intelligence or cognitive ability and that genetic variation explains a very small portion of IQ score variation. When you hear about Murray's book keep this all in mind!

          where did you find the within family SNPs? I had looked a while back but couldn't retrieve them. Can you please send me the file?

          I emailed some of the corresponding authors requesting the data. I'll want to check with them before sharing prior to publishing since it isn't really my data, or you can email yourself. They responded promptly!
