问答题 Blacks have traditionally been poorly educated—look at the crisis in urban public schools—and deprived of the sorts of opportunities that create the vision necessary for technological ambition. Black folkways in America, those unspoken, largely unconscious patterns of thought and belief about what is possible that guide aspiration and behavior, thus do not encompass physics and calculus. Becoming an engineer—unlike becoming a doctor or a lawyer or an insurance salesman—has not been seen as a way up in the segregated black community. These folkways developed in response to very real historical conditions, to the limited and at best ambivalent interactions between blacks and technology in this country. Folkways, the "consciousness of the race," change at a slower pace than societal conditions do—and so a working strategy can turn into a crippling blindness and self-limitation.
