Actually; I've only been to one single psychiatrist in my entire life, which is the one I went to in order to get diagnosed. She was very competent, so I've no idea whether or not it is a guarantee for knowing anything or not. I've heard horror stories about people being to shrinks who had no damn clue what they were talking about, though. There are plenty of stories of incompetent shrinks here in Sweden, where most doctors would rather prescribe medication than listen to your problems.
