Let me preface this by saying that economist Gregory Clark argues in "A Farewell To Alms" that one of the factors for the success of the industrial revolution was evolutionary in nature: disease killed off poorer members of the society and their position was taken over by sons of the wealthy who were less violent and more productive, thus creating the conditions needed for the industrial revolution. What I'd like to do is get my hands on some research on: 1. What percentage of people (broken down by countries perhaps) die without passing on their genes? 2. Which traits are more common among those who don't pass on their genes? 3. Which traits are more common among those who do pass on their genes? Has anyone come across any research on these topics? The idea is that by seeing what kind of people do and don't contribute to the gene pool we can predict the face of the future society. If we can find data going back far enough, we should be able to identify the effects of different cultural ideas on the gene pool. Using this information in combination with data from psychological tests from years ago, we might even be able to quantify how psychological traits correspond with reproductive success. And most importantly of all, consider the social engineering possibilities. Governments could put in place policies designed to encourage the reproduction of workers with high IQ while discouraging the reproduction of those with low IQ. The effects should be obvious in just a couple of generations and result in a high-tech society. So. Has anyone come across any research into these ideas?
