WHAT IT’S REALLY ABOUT
The Coming Genetic Arms Race: Ethics, Inequality, And Human Futures
- Dr. Jonathan Anomaly and Chris Williamson explore the ethics, history, and future of eugenics and genetic enhancement, arguing that much of what we already do in mate choice is effectively informal eugenics. They explain how technologies like IVF, embryo selection, polygenic risk scores, and future methods such as in vitro gametogenesis (IVG) could allow parents to select for traits like health, intelligence, and personality at unprecedented precision and scale. Anomaly contends that the real moral line is not between environment and genes, or between ‘eugenics’ and ‘enhancement,’ but between voluntary, welfare-promoting uses and coercive, abusive ones. They also warn that these technologies will amplify existing genetic and social inequalities, potentially drive societal stratification or even speciation, and collide head‑on with blank-slate political ideologies and collapsing birth rates in wealthy societies.
IDEAS WORTH REMEMBERING
5 ideasEugenics in practice already exists through mate choice and reproductive decisions.
Anomaly defines eugenics broadly as using knowledge of heredity to shape offspring traits, noting that sexual selection, mate preferences, and existing IVF screening are all forms of ‘soft’ eugenics long predating explicit genetic technologies.
Embryo selection with polygenic scores is already technically possible for many traits.
Using genome-wide association studies and polygenic risk scores, clinics can now rank embryos for risks of diseases (e.g., diabetes, heart disease, schizophrenia) and probabilistic traits like height and cognitive ability, allowing parents to choose embryos with substantially different life prospects.
Voluntary, welfare-enhancing genetic choices differ morally from coercive state programs.
Anomaly stresses that the crucial ethical line is between parents using options to improve their children’s welfare versus governments imposing sterilizations, bans, or mass ‘improvements’; he argues the Nazi analogy is misapplied to contemporary, consent-based enhancement.
Genetic and social inequality will likely increase, but bans may worsen it.
Assortative mating by intelligence and education is already concentrating genetic advantages; adding genetic tech will accelerate this. Outright bans would mainly push access into elite black markets, so he favors regulated access and subsidies to help ‘genetically poor’ families catch up.
Environmental and genetic interventions are ethically analogous when outcomes are similar.
The discussion likens choosing against low-IQ embryos to preventing prenatal brain damage from lead or alcohol: both are irreversible, life-shaping interventions, so privileging environment as ‘natural’ while demonizing genes is often just a naturalistic fallacy.
WORDS WORTH SAVING
5 quotesEugenics, in the broadest sense, is any attempt to harness the knowledge that we have about heredity to influence the traits of our kids.
— Jonathan Anomaly
We're already getting increasing genetic inequalities in the West without any of this technology. What’ll the technology do? It’ll accelerate those inequalities.
— Jonathan Anomaly
The decision to refrain from [embryo gene editing] is itself a form of either eugenics or genetic enhancement.
— Jonathan Anomaly
All new technology is a toy for the rich until it’s not.
— Jonathan Anomaly
The decision to do nothing is a decision to shape future humans in very specific ways, whether you like it or not.
