In page Eugenics:

"

Frederick Osborn's 1937 journal article "Development of a Eugenic Philosophy" framed eugenics as a social philosophy—a philosophy with implications for social order.[18] That definition is not universally accepted. Osborn advocated for higher rates of sexual reproduction among people with desired traits ("positive eugenics") or reduced rates of sexual reproduction or sterilization of people with less-desired or undesired traits ("negative eugenics").[citation needed]
