Dysgenics: As the World Burns
The future looks precarious. The brainy nations are becoming grayer and reproducing below the replenishment rate of 2.1 children per woman (see the nearby charts--click to enlarge).
....Globalization will continue to make migration easier. As newly-arrived, formerly destitute third-worlders enjoy the prosperity of the developed host, they become more fecund (Hispanics in the US average 2.8 babies per woman. That's higher than Mexico's 2.42 per woman, and indeed is more fertile than much of Latin America). By depressing wages and making housing less affordable, they also have the effect of decreasing the fecundity of the host country's natives. As the relative size of the smart fraction dwindles while the duller side grows proprotionally (and absolutely, of course), more human resources will have to spent by the brights to take care of the dulls. Crime and poverty will increase, living standards will be pressured, and human progression will be slowed. Source.
He then makes a few suggestions for possible remedies, possible incentives for smarter people to have more children. Good luck. The idea of artificial wombs would probably do more than most current incentives being tried around the world, and even then the idea of the creche or the kibbutz might have to be dusted off. Modern professionals do not want to sacrifice for the next generations, even though it is the next generations who will finance tomorrow's social democratic welfare states.
The outlook for Europe is particularly bad, combining dysgenics with religious antagonism. Across Europe, prisons are filling up with muslim immigrants and children of immigrants. North America does not get off free, however. Hispanic crime rates are three times higher than crime rates of americans of european origin. Mean IQ of latin american immigrants to North America is no higher than 90, which is higher than mean IQ of the muslim immigrants to Europe. The importation of third world values and traditions, along with the dysgenic impact and higher crime rates, will change the aspect of many North American and European cities.
China will not experience the same dysgenic forces What dysgenics China does experience will be due to the fact that there are far more Chinese (often of high intelligence and education) trying to leave China than foreigners trying to enter. The same applies to Russia. Japan is turning to limited time guest worker permits, and even more to robotics and automation to replace retiring workers--but not immigration, with its dysgenic potential.
Not many people are brave enough to speak about this topic in the open, due to the hypocrisy of politically correct societies. Nevertheless the research on intelligence has established genetics as considerably more important than external accoutrements, other than nutrition and early childhood experiential enrichment.
