The truth of the matter is that the Census Bureau and NPR, along with everyone else, should stop using the term race - which implies a scientific standard that simply doesn't exist - and use ethnicity, based on culture and self-definition. This doesn't mean that people stop calling themselves black or white but that we finally face up to the fact that the most important fact about race is that it doesn't exist. As I wrote about race in The Great American Political Repair Manual:
It doesn't really exist. At least not the way many Americans think it does. There is simply no undisputed scientific definition of race. What are considered genetic characteristics are often the result of cultural habit and environmental adaptation. As far back as 1785, a German philosopher noted that "complexions run into each other." Julian Huxley suggested in 1941 that "it would be highly desirable if we could banish the question-begging term 'race' from all discussions of human affairs and substitute the noncommittal phrase 'ethnic group.' That would be a first step toward rational consideration of the problem at hand." Anthropologist Ashley Montagu in 1942 called race our "most dangerous myth."
Yet in our conversations and arguments, in our media, and even in our laws, the illusion of race is given great credibility. As a result, that which is transmitted culturally is considered genetically fixed, that which is an environmental adaptation is regarded as innate and that which is fluid is declared immutable.MORE
Many still hang on to a notion similar to that of Carolus Linnaeus, who declared in 1758 that there were four races: white, red, dark and black. Others make up their own races, applying the term to religions (Jewish), language groups (Aryan) or nationalities (Irish). Modern science has little impact on our views. Our concept of race comes largely from religion, literature, politics, and the oral tradition. It comes creaking with all the prejudices of the ages. It reeks of territoriality, of jingoism, of subjugation, and of the abuse of power.
DNA research has revealed just how great is our misconception of race. In The History and Geography of Human Genes, Luca Cavalli-Sforza of Stanford and his colleagues describe how many of the variations between humans are really adaptations to different environmental conditions (such as the relative density of sweat glands or lean bodies to dissipate heat and fat ones to retain it). But that's not the sort of thing you can easily build a system of apartheid around. As Thomas S. Martin has written:
"The widest genetic divergence in human groups separates the Africans from the Australian aborigines, though ironically these two 'races' have the same skin color. ~ There is no clearly distinguishable 'white race.' What Cavalli-Sforza calls the Caucasoids are a hybrid, about two-thirds Mongoloid and one-third African. Finns and Hungarians are slightly more Mongoloid, while Italians and Spaniards are more African, but the deviation is vanishingly slight."
