However, if you have a stable population you need to make more copies of good genes and fewer of bad. It would seem likely that smart genes are being made in fewer copies each generation now. If you have a good gene, but fertility is not above replacement, how does it spread in a population? It seems bad genes can spread, but good can't in our current world. I call this the Genetic Liquidity Trap. This may be true during periods of growth in population. However, if you have a stable population you need to make more copies of good genes and fewer of bad.
