Lewontin’s famous 1972 book chapter

Few people actually read this, which is a shame because the science is interesting for historical purposes, and the fulltext of his famous fallacy is rarely read. I believe this is a pity because it is really obvious when you actually read it. Lewontin, R. C. (1972). “The Apportionment of Human Diversity”. Evolutionary Biology. pp….

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…
