I’m INTP, but the only one that is “strong” is the T, although the I and N are both pretty consistent across different tests, usually something like 60%-40%. I’ve scored as INTJ, and a lot of the P/J questions I end up just sort of picking at random at times or wisihing I could skip.
My introversion/extroversion does seem to fluctuate a lot at different points in my life. I was more extroverted when I was in the dating pool and meeting more new people.
