Right. And indeed, there is already screening for polygenic scores taking place – something I think is a pretty terrible idea given our current level of knowledge, or rather ignorance, about what most genes do. I suppose the difference is that in the 1930s there were state-driven campaigns to “improve“ the population, and these led to terrible consequences. What’s happening today is decentralised, and the result of consumer choice – which doesn’t necessarily mean it isn’t dangerous.
