" Watch a man--say, a politician--being interviewed on television, an you are observing a demonstration of what both he and his interrogators learned in school: all questions have answers, and it is a good thing to give an answer even if there is none to give, even if you don't understand the question, even if the question contains erroneous assumptions, even if you are ignorant of the facts required to answer. Have you ever heard a man being interviewed say, " I don't have the faintest idea," or " I don't know enough even to guess," or " I have been asked that question before, but all my answers to it seem to be wrong?" One does not " blame" men, especially if they are politicians, for providing instant answers to all questions. The public requires that they do, since the public has learned that instant answer giving is the most important sign of an educated man. "
