The reputation of eugenics started to decline in the 1930s, a time when Ernst Rüdin used eugenics as a justification for the racial policies of Nazi Germany. Adolf Hitler had praised and incorporated eugenic ideas in Mein Kampf in 1925 and emulated eugenic legislation for the sterilisation of "defectives" that had been pioneered in the United States once he took power. Some common early 20th century eugenics methods involved identifying and classifying individuals and their families. This included racial groups (such as the Roma and Jews in Nazi Germany), the poor, mentally ill, blind, deaf, developmentally disabled, promiscuous women, and homosexuals as "degenerate" or "unfit". This led to segregation, institutionalisation, sterilisation, and mass murder. The Nazi policy of identifying German citizens deemed unfit and then systematically murdering them with poison gas, referred to as the Aktion T4 campaign, paved the way for the Holocaust.
By the end of World War II, many eugenics laws were abandoned, having become associated with Nazi Germany. H. G. Wells, who had called for "the sterilisation of failures" in 1904, stated in his 1940 book The Rights of Man: Or What Are We Fighting For? that among the human rights, which he believed should be available to all people, was "a prohibition on mutilation, sterilisation, torture, and any bodily punishment". After World War II, the practice of "imposing measures intended to prevent births within [a national, ethnical, racial or religious] group" fell within the definition of the new international crime of genocide, set out in the Convention on the Prevention and Punishment of the Crime of Genocide. The Charter of Fundamental Rights of the European Union also proclaims "the prohibition of eugenic practices, in particular those aiming at selection of persons".
=== In Singapore ===
Lee Kuan Yew, the founding father of Singapore, actively promoted eugenics as late as 1983. In 1984, Singapore began providing financial incentives to highly educated women to encourage them to have more children. For this purpose was introduced the "Graduate Mother Scheme" that incentivised graduate women to get married as much as the rest of their populace. The incentives were extremely unpopular and regarded as eugenic, and were seen as discriminatory towards Singapore's non-Chinese ethnic population. In 1985, the incentives were partly abandoned as ineffective, while the government matchmaking agency, the Social Development Network, remains active.
== Modern eugenics ==
Liberal eugenics, also called new eugenics, aims to make genetic interventions morally acceptable by rejecting coercive state programmes and relying on parental choice. Bioethicist Nicholas Agar, who coined the term, argues that the state should intervene only to forbid interventions that excessively limit a child’s ability to shape their own future. Unlike "authoritarian" or "old" eugenics, liberal eugenics draws on modern scientific knowledge of genomics to enable informed choices aimed at improving well-being. Julien Savulescu further argues that some eugenic practices, like prenatal screening for Down syndrome, are already widely practiced, without being labelled "eugenics", as they are seen as enhancing freedom rather than restricting it. UC Berkeley sociologist Troy Duster argued that modern genetics is a "back door to eugenics". This view was shared by then-White House Assistant Director for Forensic Sciences, Tania Simoncelli, who stated in a 2003 publication by the Population and Development Programme at Hampshire College that advances in pre-implantation genetic diagnosis (PGD) are moving society to a "new era of eugenics", and that, unlike the Nazi eugenics, modern eugenics is consumer driven and market based, "where children are increasingly regarded as made-to-order consumer products". The United Nations' International Bioethics Committee also noted that while human genetic engineering should not be confused with the 20th century eugenics movements, it nonetheless challenges the idea of human equality and opens up new forms of discrimination and stigmatisation for those who do not want or cannot afford the technology. In 2025, geneticist Peter Visscher published a paper in Nature, arguing genome editing of human embryos and germ cells may become feasible in the 21st century, and raising ethical considerations in the context of previous eugenics movements. A response argued that human embryo genetic editing is "unsafe and unproven". Nature also published an editorial, stating: "The fear that polygenic gene editing could be used for eugenics looms large among them, and is, in part, why no country currently allows genome editing in a human embryo, even for single variants".
== Contested scientific status ==
One general concern is that the reduced genetic diversity that may be a feature of long-term, species-wide eugenics plans could eventually result in inbreeding depression, increased spread of infectious disease, and decreased resilience to changes in the environment.
=== Arguments for scientific validity ===
In his original lecture "Darwinism, Medical Progress and Eugenics", Karl Pearson claimed that everything concerning eugenics fell into the field of medicine. Anthropologist Aleš Hrdlička said in 1918 that "[t]he growing science of eugenics will essentially become applied anthropology." The economist John Maynard Keynes was a lifelong proponent of eugenics and described it as a branch of sociology. In a 2006 newspaper article, Richard Dawkins said that discussion regarding eugenics was inhibited by the shadow of Nazi misuse, to the extent that some scientists would not admit that breeding humans for certain abilities is at all possible. He believes that it is not physically different from breeding domestic animals for traits such as speed or herding skill. Dawkins felt that enough time had elapsed to at least ask just what the ethical differences were between breeding for ability versus training athletes or forcing children to take music lessons, though he could think of persuasive reasons to draw the distinction.
