My father told me ages ago all the psych types he worked with in mental wards struck him as being in the field to diagnose what was wrong with themselves.
My Mother used to say, “some people are so smart, they’re stupid”. That explains Washington D.C. and Sacramento, CA.
My father told me that exact same thing eons ago. One of his best friends was a psychiatrist so he had first hand knowledge. My psych major niece fits the profile as well.
