I took this personality test in middle school and I was INTP. In high school, I was an ENTJ. I took this test a year ago and I was ENTP (but I do remember that the T and F was almost perfectly equal). Interesting to see how my personality has changed as I've matured!
It's not really supposed to change. This particular test is rather short and would be more likely to change results as your view of yourself changes over time. You might straddle two types like the ENTJ and ENTP, though I doubt you were ever actually an INTP given your extravert score. Perhaps you were just shy back in middle school? (extraverts can be shy - that has more to do with social anxiety than social preference)
Yeah, I was extremely shy in middle school; lifelong anxiety issues. As for the rest of the changes, I've only through therapy in the last year really ever began understanding and trusting emotions outside of a rational context, so I can definitely understand the shift from T to F there.
