Embryo selection is a potential emerging technology and is the subject of several previous Metaculus questions and a notebook. In particular, two previous questions asked about embryo selection for intelligence in the United States.

A 2020 Pew poll found that 17% of Americans said it would be appropriate to "change a baby’s genetic characteristics to make the baby more intelligent", and another poll found Democratic support at 18% compared to Republican support at 13%. Some on the left have referred to embryo selection as eugenics.
