Dismissing false Experts

One of the problems one has in life is dealing with people who know nothing whatsoever about the subject they are most aggressive in discussing; in particular, those people who supposedly occupy positions of authority and have academic credentials in their fields of alleged expertise. The others one can safely ignore, but "experts" usually have to be responded to in some polite manner. People who have true knowledge have wide knowledge. This is because they are all naturally curious, and also have an ability to associate many diverse ideas and facts into a coherent structure. As we say, in martial arts terminology: they have "strong foundation" (in the arts, the saying is that a boxer's legs go first, meaning that they are no longer able to step, slip and slide, side to side, quickly in the ring); so, for any scholar, the same truth shall apply---knowledge is based, literally, on deep, strong roots that have multiple sources of nourishment. The trick then in dealing with these false, faux scholars is to divert them onto another detour to see if their knowledge is broadly based: talk to a carpenter about plumbing and a writer about mathematics, or a physicist about biology. If they lack knowledge in another field somewhat related to their own field; they shall then lack a deep knowledge in their own field. It's an easy and non-threatening way to deal with "experts." One then can safely dismiss their false opinion.
