The word eugenics usually ends debate before it begins. It evokes forced sterilization, racial planning, and the worst crimes of the twentieth century. That reaction is understandable. But it also hides an important distinction. Not every attempt to influence heredity is the same. There is a world of difference between state coercion and private choice.
Today, millions of people already make reproductive decisions based on genetics. They screen embryos, test for inherited disease, and avoid passing on severe disorders. Whether we like the term or not, the old question has returned in a new form. The real issue is no longer whether eugenics exists, but who controls it.
The answer depends on whether we are dealing with authoritarian eugenics, liberal eugenics, or what might be called libertarian eugenics.
Authoritarian Eugenics: Biological Central Planning
The original eugenics movements were products of the modern administrative state. Politicians, academics, and reformers believed society could be scientifically improved by controlling who reproduced. In the United States, numerous states adopted forced sterilization laws. Progressives and technocrats often supported these measures as enlightened social policy.
This was not merely bad ethics. It was also bad economics.
Like all central planning, authoritarian eugenics assumed that a small group of experts possessed enough knowledge to redesign a complex social order. Ludwig von Mises showed why such thinking fails. Central planners cannot gather the dispersed knowledge embedded in millions of individual choices. They replace spontaneous order with bureaucratic command. The result is not rationality, but what Mises called planned chaos.
The same logic applies to reproduction. No board of experts can objectively define human value, predict future social needs, or determine which traits should prevail. Intelligence, temperament, creativity, resilience, and moral character emerge through combinations too complex for political management. Once the state claims authority over heredity, error becomes tyranny.
That is why Mises opposed both eugenics and social darwinism. Human flourishing comes through cooperation, exchange, and civilization, not through administrative breeding programs.
Liberal Eugenics: Choice Inside the Regulatory State
Modern biotechnology changed the terrain. Instead of governments sterilizing citizens, parents can now make private choices. Genetic screening can reduce the odds of passing on Tay-Sachs, Huntington’s disease, or other severe disorders. IVF clinics already allow embryo selection in many countries.
This is often called liberal eugenics: the use of reproductive technology through voluntary decisions rather than coercion.
Whatever one thinks of the label, it is fundamentally different from the old model. No police force compels conception. No ministry assigns breeding permits. Families choose according to their own values.
Even controversial cases reveal this distinction. In a widely discussed case, a deaf couple deliberately sought a sperm donor likely to produce a deaf child, viewing deafness less as a disability than as a cultural identity. Many found the decision troubling. But the controversy itself proved the point: modern genetics raises questions of preference, pluralism, and parental authority, not simply dictatorship.
Markets already handle morally complex choices every day. People choose schools, doctors, neighborhoods, diets, and lifestyles based on competing values. Genetics extends that frontier.
The danger, however, is that liberal eugenics still operates inside a political framework. Licensing boards, subsidies, bans, mandates, and insurance systems can easily convert private choice into soft coercion. Once bureaucrats decide which traits deserve funding and which deserve prohibition, we drift back toward central planning.
Libertarian Eugenics: Decentralized Human Selection
A genuinely libertarian approach begins with self-ownership, private property, freedom of association, and voluntary exchange. It rejects all state control over reproduction while allowing peaceful individuals to use lawful technologies as they see fit.
That means parents may seek to avoid disease. Others may prefer natural reproduction. Religious communities may reject genetic intervention entirely. Experimental communities may embrace enhancement. Different norms can coexist because no central authority imposes one model.
This is where libertarianism offers something deeper than either prohibition or technocracy: competition among ways of life.
Jeremy Kauffman has provocatively spoken of something like a “libertarian gene.” He does not mean a single gene that mechanically produces Rothbard readers or tax resisters. Rather, he points to growing research suggesting that political temperament may be partly heritable. Traits such as openness to risk, low conformity, distrust of authority, independence, and tolerance for social experimentation may have biological components. If so, libertarianism may not be only an ideology learned through books. It may also reflect underlying dispositions.
That would explain an old puzzle of politics: why some people encounter the same arguments for freedom yet remain instinctively hostile to them, while others embrace them almost immediately. Reason matters, but reason often sits on top of temperament.
If libertarian inclinations are unevenly distributed, then Kauffman argues that libertarians should think less like missionaries and more like founders. Instead of trying to persuade entire mass democracies, they should concentrate geographically with those already sympathetic to liberty.
The Free State Project follows precisely this logic. Rather than winning a national election, thousands of libertarians moved to New Hampshire to build local influence through migration, association, and concentration. The Amish achieved something similar in another form: a durable semi-autonomous order built through community norms, fertility, and separation from mainstream institutions.
This is not state eugenics. No one is forced. No one is sterilized. No one is classified by a ministry of health. It is selection through voluntary sorting, family formation, culture, and migration.
Over generations, communities formed around shared values often reproduce those values both culturally and, potentially, biologically through assortative mating. People tend to pair with those who resemble them in beliefs, habits, education, and temperament. If political disposition has any heritable component, then a concentrated libertarian population could gradually reinforce libertarian traits without a single law being passed.
In that sense, libertarian eugenics would not be a breeding program. It would be the spontaneous order of heredity itself.
The twentieth century tried to improve mankind through the state. It produced horror.
The twenty-first century may instead see communities shaping their future through freedom, family, and voluntary association.
