We strongly support Cattell four-child goal as a reasonable minimum goal. The current fertility rates for Americans is slightly below replacement level and rates for well-educated Americans are far below replacement level. While we support the concept of Zero-Population Growth or even a population contraction for our society and for the world, we don't think that the elimination of genes associated with higher levels of intelligence is good either for the future of our world or for the attainment of the ZPG goal. For the world as a whole, the answer to the falling levels of genetic intelligence must primarily consist of educated couples raising their average fertility rate to at least the average for society as a whole. However, our community can both try to attract members who are already blessed with high intelligence and also make use of artificial insemination or egg donation to achieve this goal.
Egg donation is an expensive process.
This is actually a very good investment, but it is obviously better for a woman to have children earlier in life before her own eggs have deteriorated. Ideally, we would like as many children with high intelligence as possible. Of course, we should love and care for every child we have with an equal amount of effort and commitment. However, it seems only sensible to want the best for every child we have. It is fairly easy to find and recruit men with SAT scores of 1500 or above with excellent health and family backgrounds to be semen donors.
