Third hand anecdote re: your footnote: a good friend of mine has a mother who she says is a narcissist, and the behaviour she describes is “can’t stand the thought she might have flaws, evidence of a flaw is brutally suppressed, reacted to with anger, blame, denial, gaslighting and displacement, and if a thought like ‘I am not perfect, specifically this is a way that I am not the best/someone else is better than me’ does get through the defenses, it results in a mental collapse and period of weeks filled with only negative thoughts, expressed to others to try and build back up her sense of self worth by getting people to say she’s wrong about the negative thoughts”. It’s like this person can’t occupy the mental territory “I’m OK, mostly good” it’s either “I am fantastic” or “I am terrible”.
I would be unsurprised if different people exhibiting narcissistic behaviour had different reasons for doing so, and some just straight up think unreasonably highly of themselves and are resistant to evidence to the contrary, without it being a defense mechanism, while others were like the anecdote above.
