Roles of science in eugenics

The relationship of eugenics to science is intricate and many-layered, starting with Sir Francis Galton’s original definition of eugenics as “the science of improving stock”. Eugenics was originally conceived of not only as a science by many of its proponents, but as a new, meliorative science emerging from findings of a range of nascent sciences, including anthropology and criminology in the late 19th-century, and genetics and psychiatry in the early 20th-century. Although during the years between the two World Wars many central claims made by eugenicists were critiqued by scientists in these disciplines, in more recent years forms of eugenics (e.g., liberal eugenics”) have been defended as an inevitable outcome of biotechnologies and respect for autonomous choice. Understanding the shifting and varied roles that science has played in eugenics requires an appreciation of the ways in which science and values are intertwined.
