I usually get ENFP and on rare occasions very rare INTP. if someone is typist against SJs they'll say that if they want to insult me, but really? I don't take that as a mistype more as a them trying to piss me off, it doesn't work.
I've never been mistyped by a person, as I hardly know anyone in real life who is familiar with MBTI. Tests have mistakenly typed me as INTP, INFP, and ISTJ.
I've never been mistyped by anyone in real life either, as my friends either don't know/care about mbti, or aren't obsessed with it so wouldn't try typing me as something else anyway!
I've met multiple people from typ-c, though, and even when I was questioning my type they all seemed to think INFJ was obvious. Same w/ via email w/ a few people on here - even when I tried to argue other possibilities for myself, they wouldn't deviate from the infj prognosis!
In my early 20's though I never tested as an F - I always came out INTJ (although T was the weakest preference of the 4).
