I think he’d be a grandiose narcissist. He truly believes he’s the best and can’t be wrong. And when someone calmly and carefully explains why he is wrong about a particular thing, his mood flips 180 degrees and he blows up and gets super defensive. If we don’t give up trying to convince him, his mood gets even more sour and he essentially mopes like toddler. This can be for anything, even the most trivial bullshit that wouldn’t phase anybody else.
And he does all that while bragging to anyone that will listen that he’s open-minded and loves being proven wrong.
Oh yeah, that last point rings true for my dad too. My family hired a health aid to assist with our relative who he’s helping care for in home hospice, and we fought with him for weeks to defer to the aid’s expertise. He believes, despite the fact that this is literally her career, that he knows better how to take care of someone on their deathbed. Despite not having gone through it before, or having any medical or healthcare experience. He would snap at the aid for showing him how to do something.
We ultimately had to have a heart-to-heart with the aid to apologize for his behavior and to teach her how to use his own narcissism against him so he would do things the right way.
