"Denouncing Nazis and appealing to national defense were only a few immediate ways in which eugenicists sought to cleanse their branding of negative associations. In 1948, the American Society of Human Genetics founded and had high leadership crossover with the American Eugenics Society so it could easily be seen as an effort at rebranding. However, many human geneticists still described themselves as eugenicists, although some tried to distance themselves from older eugenics practices. For example, geneticist James Neel once in 1954 described his work as “new eugenics, where I define eugenics simply as a collection of policies designed to improve the genetic well-being of our species” [12].
