Is selecting embryos to avoid devastating diseases the same thing as eugenics?
Jonathan Anomaly of Herasight says no—and the data behind his argument might change your mind.
In this episode of Optimists Make Money, we go inside the world of embryo selection and polygenic risk scoring—the technology letting parents assess real disease risk (schizophrenia, diabetes, certain cancers) in embryos during IVF, before a pregnancy even begins.
I recently caught up with Jonathan to dig into the taboo head-on:
In our interview you’ll hear:
How polygenic risk scores are calculated from biobank data
Why embryo selection for disease risk is legal in the US but restricted in the UK
Where Jonathan thinks the eugenics comparison breaks down
What's next for genetic screening technology in IVF
The line between disease prevention and trait selection
