1990s books and articles by William H. Tucker are outstanding, and include some interesting insider information.

I can get back with more later. For now, here is a 1942 IQ test used by doctors in Germany to support the "clinical execution" of an 11-year-old German boy. From the 1994 edited book, "Cleansing the Fatherland" (G. Aly et al.).

Thank you for this excellent article. If you decide to write a follow-up to this story, I suggest looking into the "high IQ heritability" pseudoscience that race scientists cite in support of their claims, which mainly consists of twin studies.

Researchers who conducted 20 years of psychiatric and schizophrenia candidate gene studies never seemed to be embarrassed that these studies crashed and burned. One wonders how researchers making current claims about GWAS/PRS/CNV will react when these studies inevitably crash and burn.

GWAS problems aside, the article fails to mention that Bouchard never published his 16PF personality results, or that Plomin's 1998 adoption study found no personality test score correlation between birthparents and their 240 adopted-away 16-year-old biological offspring. gwern.net/doc/genetics...
