Scientists are also notorious for being ideologically infiltrated by authoritarian or totalitarian ideologies/regimes. https://en.wikipedia.org/wiki/Lysenkoism The Soviet Union was convinced that collectivism was the ultimate form of human society and organization. Lysenkoism fed their biases, and Soviet Agrarian scientists struggled to point out the new collective experimentation by the government was a disaster (a similar problem was faced by Chinese scientists and Bureaucrats trying to implement Mao's great leap forward). https://en.wikipedia.org/wiki/Phrenology Nazi Germany was convinced they were the greatest race on Earth, that Jews and Slavs were sub-human. Phrenology promised them a way to determine racial purity and back it up with scientific results. The scientific community brought us lobotomies and eugenics too.
