Yeah, the Myers-Briggs isn't really a reliable "quiz", but the 16 results are all things you should be able to figure out yourself, since the Myers-Briggs was composed with the idea of understanding oneself more, you don't need to take the quiz at all, actually. Just need to know what the results are and check it with yourself.
Nobody looks into the Myers-Briggs for anything except fun anyways. I met someone who took it really seriously, though, once. It was kind of awkward.
My brother and I are twin ISFPs.
