“[F]or a social theorist ignorance is more excusable than vagueness. Other investigators can easily show I am wrong if I am sufficiently precise. They will have much more difficulty showing by investigation what, precisely, I mean if I am vague. I hope not to be forced to weasel out with 'But I didn’t really mean that.' Social theorists should prefer to be wrong rather than misunderstood. Being misunderstood shows sloppy theoretical work.”
