SO FRUSTRATING. There were many times that Haier talked about shifting the bell curve or lowering the number of people with IQs below 85. And every time Lex stopped him. WHY!! This is so relevant. If we could do this it would have a profound impact on society. Haier talked about what did not work but he wanted to talk about what could. We got hints: lead poisoning, nutrition and I can think of others like fetal alcohol syndrome. I wish he was allowed to elaborate. Otherwise a really fascinating interview. Lex please bring him back and explore this.,(reply>), If you have heard about crispr there is interesting theories that by turning on certain intelligence genes we could raise intelligence by magnitudes of order
