You're completely wrong and if you looked into it, you would find that out. However you're not going to look into it. The reasons why are (1) that you have heard that "MBTI doesn't work", because the "dichotomy spectrum test" as adminstered via pimple-faced HR grads and Facebook quizzes has low replication (and any responses to "debunking" may as well be ducks quacking as far as "debunkers" are concerned), and (2) it is culturally identifying for debunkers to caustically criticize anything that "smells of woo", and to give ideas that smell of woo a fair hearing is just not done, in debunker culture. Debunkers are shallow, motivated reasoners, and in my experience anything they hate and mock is always very interesting to look into. ("BUT WHY WOULD YOU IT'S RUBBISH" they sneer.)

You're going to get upvoted, and I'm going to get downvoted, because trying to explain how functional preference orders (Ni-Fe-Ti-Se) relate to MBTI is somewhat analogous to posting an explanation of how Vedic astrologers use natal charts; the immediate result is that a crowd of Dunning-Kruger's poster children will respond to the explanation with "LOL HOW CAN 1/12 OF HUMANITY HAVE THE SAME DAY PREDICTED IN THE NEWSPAPER, FUCK YOU HAVE A DOWNVOTE YOU FUCKER".
