      Have we reached enough known intelligence genetic variants to justify IVF embryo selection by genetic testing?

      Not yet. The polygenic scores can still only predict a small % of IQ variance. But that will probably keep increasing in the next few years.

      Never. Each individual locus only affects intelligence to the tune of a fraction of a percent...

      ... and IVF embryo selection can only select on at most a very few loci at once.

      Think about it. Here we have 536 genes explaining 4% of intelligence variation.

      So the maximal IVF selection would give you a 4% tweak to intelligence one way of the other. Small beans, tho still ethically unacceptable.

      Why ethically unacceptable? Is selective mate choice ethically acceptable?
