Selection, because of the Christard ban on gentile money-lending Ashkenazi Jews were solely responsible for banking in Europe. Other jobs were unavailable to them since Christards viewed banking as evil and the other jobs as noble so the Jews in Europe were solely 'relegated', for lack of better word, to banking. Now to succeed in banking intelligence is a great asset as it allows the banker to make better decisions, those Jews who were stupid made less smart decisions and didn't have the monetary means to afford a family. Several generations passed and the stupid genes were weeded out of the Ashkenazi population. This also explains why Ashkenazi Jews have more often than not wealthy families, they were practically given a monopoly on banking by Christards.
