" I had the foolish idea that we should test for desirable and useful traits so that we could assemble ideally balanced teams to the colonies. [...] It's like those foolish attempts to control immigration to America based on the traits that were deemed desirable, when in fact the only trait that defines Americans historically is "descended from somebody willing to give up everything to live there. "
