The difference between the behaviors manifests in default cognitive tunnelling combined with not keeping up with social rules and cues -- from perceived and expressed superiority of self and inferiority of others.
If one removes said cognitive tunnelling and social issues out of the way, would they still have the same superior self and inferior other?
And does the lack of superior self and inferior other very reliant on said cognitive tunnelling and social related issues that just looked like arrogance?
Is someone bombarded by the senses, thoughts and feelings -- usually ended up freezing because of too many processes or had those things into a stream of an expression (infodump), especially one that has issue just as related to gear shifting from said initial senses, thoughts and feelings unto a completely different realm that is the outside of said thoughts, feelings and even senses by itself -- an arrogant person?
It's the same vein as uneven developmental emotional profile, mistaken for personality disorders like narcissism, really.
Or how about alexithymia traits made autism became associated with psychopathy along with the lack of empathy crap and incapable of feeling emotions?
Or basically anything executive dysfunction, really -- be it mental illness or neurodivergence or basically "not expected" or "not by minimum standard" mistaken for some aligned agenda personality flaw than something else?
Or how about physical symptoms mistaken for psychiatric illness because behavioral?
I could go on and on and on about it -- the internal processes and intent vs the perceived external because the behaviors out of it 'doesn't socially vibe'. 
Personally, it's just another aspect of executive functioning to me.
And nothing to do with whatever social dynamics because I don't even have a social interest to play superiority and inferiority complexes.
To transition between internal indulgences and whatever focus I prefer to not be disrupted over -- towards external interest and social attention.
To anyone else, they don't care. They don't care if it's executive dysfunction or because you're not fast enough.
They just feel neglected, ignored, unheard, awkward or whatever.
Do I perceive myself superior because of my supposedly "priority" is not them first?
No. Because I do not see the point of comparisons. Transition is transition.
But do I perceive them inferior to be ever be a priority to me?
No.
I don't even care who's superior or inferior, but that's their perception.
