   mean expectation of 119, but the distribution indicated that there was a   
   12% chance that the kid could have an IQ below 80.  The Herasight guy   
   just claimed that that was the probability estimates that the parents   
   had to deal with when making their embryo selections.  Before I retired   
   we did a much better job at predicting breeding values using genomic   
   selection than they can do for IQ.  One of our most important traits was   
   feed conversion and it has a published heritability (in the narrow   
   sense) of only around 0.2 and we have to do much better than Herasight   
   to make everything cost effective (we can't afford to be so wrong so   
   often because of our breeding population size limits).  There are   
   estimates of heritability in the narrow sense for IQ of around 0.5, but   
   the estimate is likely bullshit because they know that they haven't   
   figured out how to measure the trait, let alone build a population   
   suitable for measuring the heritability accurately.  Wiki notes that the   
   estimate drops to 0.3 when culture is factored in.  The heritability for   
   human height is pretty firm at around 0.8 because it is based on   
   millions of observations in multiple environments and cultures, but even   
   human height can be significantly affected by environment.   
      
   You have to consider the fact that non Africans took only a fraction of   
   the genetic variation that existed in Africa with them when that sub   
   population left Africa 60,000 years ago.  Did they leave the worst   
   genetics behind.  Was there anything that they should have taken with   
   them, but they did not due to founder effects for that sub population?
