One-Upmanship and Folk Psychology

From Stephen Potter, One-Upmanship, p. 22:

"After this opening treatment, Doctor may, under certain circumstances, ask Patient his symptoms. But he will let it be seen that he is not listening to what Patient is saying, and may place his hand on Patient's wrist, or better, stomach, as if to suggest that he as Doctor can tell more through the sensitive tip of one finger than from listening to the layman's self-deceiving, ill-observed, and hysterically redundant impressions of what is wrong with him".
