Would it be possible to have a world in which human beings of all kinds and races are free to study what they want, and to be hired depending simply upon their merit and ability, and not  upon "the science of the subject," which may well prove to be premature? We are far from finished  investigating the "Nature and Nurture" aspect of the subject, which may vary markedly from time to time and from race to race. We also do not know what causes the "excess testosterone" in utero that (allegedly) predisposes males to STEM subjects and females away from them. Since we really and truly do not yet know the definitive answer, can we please remain open and simply employ the best and the brightest beings until we know better (if ever?)?
