I can compare. I used to think I had PoLR, now I don't. I used to think my "Supervisor" made me uncomfortable, now the exact same person doesn't. It was all in my head. It has more to do with how I feel about the person rather than the other way around. How I think about myself creates potentials within myself that I can follow or ignore.
See, people make assumptions about themselves or the world. Then often, they are proven wrong by new experience.
Socionics might make that observation about you, and say you are that way forever.
It could be true that you will be that way forever, or it could not.
Again, previous experiences are proven wrong by new experiences. What was true about you could change. Actually, it's what you think is true about yourself. You don't really know what you're "really" like, because what you know about yourself could be wrong.
Hence, I don't think it's very meaningful to make an observation, and say that that observation will stay the same forever. Because you could easily make the wrong observation.
