Today I seem to be an INFJ. The I and the N are solid, but the F and the J are wobbly: in high school I’m pretty sure I got INFP, a few years ago INTJ. But the wobblyness doesn’t help with the freedom issue, since it stems from pretty stable ambiguities in my personality: for instance I am consistently not sure whether to trust thinking or feeling more; the questions always bother me. But for some reason it doesn’t bother me, this having a personality. And these quizzes give way better random flattery than horoscopes (helps to have at least something to target at).

I can never remember what I get from one test to the next (hopefully I will, this time, I’ve got a written record I can’t easily lose) - and my results vary for the same reason as you. Everyone on the internet says mood variation, or even deceit, shouldn’t matter that much, because there are alarms for that in these kinds of tests, and I wonder what sort of mechanism that could be. No doubt lots of research has gone into it.

My issue with freedom: I don’t mind having a personality and behaving in a way determined by that personality, I mind having only one, and not being able to be flexible and clean the slate to begin again as someone else. But then I’ve always felt that way. It just comes on stronger some times than others. There was a particularly awful half hour I had when I was in the fourth grade, when I realized my face was basically unalterable - I was stuck with me. I try and avoid thinking about it, but I can’t change it, no matter how much energy I use, no matter how many different ways I channel it.
