“One of the many interesting and appealing things about questioning is that it often has an inverse relationship to expertise—such that, within their own subject areas, experts are apt to be poor questioners. Frank Lloyd Wright put it well when he remarked that an expert is someone who has “stopped thinking because he ‘knows.’”2 If you “know,” there’s no reason to ask; yet if you don’t ask, then you are relying on “expert” knowledge that is certainly limited, may be outdated, and could be altogether wrong.”
