I've taken several of these tests and I always get different results that always start with I, with ISTJ being the most common but I'm not really vibing with the description of the type, and the stigma that all ISTJs are boring and love traditions and conservatism too much.
I always have issues when the test gives me a vague question that I just don't understand, or find relatable in any way.
From the descriptions given here in the post I guess I'm an IS??P. (and taking the test right now gave me the same type, with 81% introversion). But also I feel like MBTI doesn't take into account stuff like mental illness (depression or anxiety that can lead to far more introverted behaviour than a person would be if they didn't have depression and\or anxiety) or in my case, autism, which also puts a bit of distance between me and people. I could argue that most of my introversion is kinda learned due to experiences of being excluded while growing up and learning to enjoy solitude.
ngl the biggest reason I wanted to know my type is to see what fictional characters have it according to a few blogs that analyse characters in that way.
Edit: to make my comment more fun here's a link to Funky MBTI in Fiction, a blog that analyses fictional characters and assigns them MBTI and Enneagram types
speaking of personality stuff, have you ever heard of Enneagram? It's also a personality type system, and I personally find it a bit more accurate.
