“In psychiatry, patients don't produce information as easily as they do in other medical settings. Most patients with physical disorders are frightened by their pain and eager to give information about it. Psychiatric patients have a very different relationship to their symptoms and don't always want to answer questions. Gertrude's patient probably found his rituals deeply embarrassing. He probably wanted the help, but he also probably wanted to tell this stranger as little as possible to get it. The paranoid patient, who has an unrealistic fixed belief that people are out to get him, may not feel, at the time, that it is of any relevance to the doctor that there is a conspiracy of aliens against him. The manic-depressive patient, whose judgment is usually quite poor during periods of illness, may take a dislike to the doctor and say that she has been behaving perfectly normally. Interviewing a psychiatric patient can be like trying to catch fish with your hands.”
