Liberal eugenics, also known as new eugenics and consumer eugenics, is a neologism for a claimed ideology which advocates the use of reproductive and genetic technologies where the choice of enhancing human characteristics and capacities is left to the individual preferences of parents acting as consumers, rather than the public health policies of the state. The term was coined by bioethicist Nicholas Agar.[1]


The term refers to an ideology of eugenics inspired by liberal theory and contrasted from the coercive state eugenics programs of the first half of the 20th century.[2] The sterilization of individuals alleged to have undesirable genes is the most controversial aspect of those programs.[1]

Historically, eugenics is often broken into the categories of positive (encouraging reproduction in the designated "fit") and negative (discouraging reproduction in the designated "unfit"). According to Edwin Black, many positive eugenic programs were advocated and pursued during the early 20th century, but the negative programs were responsible for the compulsory sterilization of hundreds of thousands of persons in many countries, and were contained in much of the rhetoric of Nazi eugenic policies of racial hygiene and genocide.[3]


Liberality versus illiberality[edit]

Dov Fox, a law professor at the University of San Diego, argues that liberal eugenics cannot be justified on the basis of the underlying liberal theory which inspires it. He introduces an alternative to John Rawls's social primary goods that might be called natural primary goods: heritable mental and physical capacities and dispositions that are valued across a range of projects and pursuits. He suggests that reprogenetic technologies like embryo selection, cellular surgery, and human genetic engineering, which aim to enhance "general purpose" traits in offspring are less like childrearing practices a liberal government leaves to the discretion of parents than like practices the state makes compulsory.[4]

Fox argues that if the liberal commitment to autonomy is important enough for the state to mandate childrearing practices such as health care and basic education, that very same interest is important enough for the state to mandate safe, effective, and functionally integrated genetic practices that act on analogous all-purpose traits such as resistance to disease and general cognitive functioning. He concludes that the liberal case for compulsory eugenics is a reductio ad absurdum against liberal theory.[4]

According to health care public policy analyst RJ Eskow, "libertarian eugenics" is the term that would more accurately describe the form of eugenics promoted by some notable proponents of liberal eugenics, in light of their strong opposition to even minimal state intervention in eugenic family planning, which would be expected of a social liberal state that assumes some responsibility for the welfare of its future citizens.[5]
