It’s interesting that Germany looked to the US for it’s ideas on eugenics.
Excerpt from link:
Though they couldn't possible know it, the children of the Fernald State School were the victims of bad science and a newly developed bureaucracy designed to save America from the so-called "menace of the feebleminded." Beginning early in the twentieth century, United States health officials used crude versions of the modern IQ tests to identify supposedly "deficient" children and lock them away. The idea was to protect society from potential criminals and to prevent so-called undesirables from having children and degrading the American gene pool......
...... It reveals the danger in misguided science, the fearsome power of unchecked bureaucracies,
So? It also looked to the US for its ideas on assembly lines.
