I took a course on Freud in college, and what struck me at the time was that the framework of psychoanalysis seemed basically cruel, in that the analyst was free to say that either acceptance or rejection of their claims was evidence for them, and that it would be maddening to deal with that for any extended period of time.

Well, it's clear to me that you're only saying that because of unresolved feelings towards your mother.

I’m not OP but I felt that one. I have at times avoided socializing, not because of a superiority complex, but from anxiety

I interpreted the “uninterested in giving … attention” part of that point a bit differently. To me, somebody avoiding socialising is not giving off a superiority complex. I suspect what the author meant is being inattentive while socialising (i.e., not actually listening to you, focusing the conversation on themselves, etc.)
