I’m not sure what you mean by ‘normal breeding of adults’, but Hsu’s proposal would be basically an augmented IVF: you do IVF as usual, sequence each of the embryos to get an estimate of IQ/whatever, and implant the highest-scoring one (usually referred to as just ‘PGD’); the embryo develops into an adult, and you repeat the process.
Each generation could get a boost of maybe 5 points (it depends on how many embryos you can produce and how accurate your estimate is and how much of IQ turns out to be genuinely genetic), so in a century that could add up to quite a bit.
Ah I see, so the selection step is still in vitro, but not the entire lifecycle of an iteration. The wording had been confusing me. Thanks for clearing that up!
What would non-in vitro iterated selection be, just normal breeding of adults?
