When I was a graduate student at the University of Chicago, a very long time ago, it was common for undergraduate acquaintances to have, and talk about having, a shrink—a psychoanalyst. I never saw much evidence that psychoanalysis was improving their psyches to any significant degree, which led me to suspect that the real function of the shrink was to make the patient feel better, and perhaps more important, by paying attention to him or her. A friend who was getting his doctorate in psychology asked one of his professors what the evidence was that psychoanalysis worked, read the articles the professor suggested, and concluded that the evidence was that it didn't; I take that as at least mild support for my interpretation of the role of the shrink.
So far as I can tell by very casual observation, the shrink has pretty much vanished from that particular role, being replaced by the trainer, aka coach, someone hired to provide advice to his client on how to live his life. As best I can tell, being hired for that job does not, in practice, require any evidence of expertise in living one's own life.
Nor does it require the eight years of medical school plus residency that were the entry requirements for becoming a shrink, but not truly essential for the job of making clients feel as though someone is paying attention to them. It's nice to see progress in the world.
