The movement for the better brain started much before half a century ago.<p>If you study Jewish history you will find out they have been doing this all along. For instance, as a very literate culture, they would encourage the less capable of learning to leave the faith, much like a Rumspringa without end. This had the effect of culling the less intelligent, which was an effect they understood and seeked purposefully. On the other side of the coin, as opposed to Christianity which discourages its representatives (priests) from reproducing, Rabbis were encouraged to have prolific offspring on account of their being the most educated people, and the community engineering so that there will be more intelligent Jews (sons of cultured Rabbis) than unintelligent ones (those who are encouraged to give up on faith studies).<p>But yes, evil Germans and their eugenics, carry on.
