I can't figure out my MBTI type, and here are the facts.
I have taken several MBTI tests and have scored ENTP and INTP equally, with some scattered INTJ scores.
I have taken a Socionics test that told me I was an LII (INTj, or MBTI INTP) but also told me that I was 99% as likely to be an ILE (ENTp and ENTP) and 97% as likely to be an ILI (INTp or MBTI INTJ).
My enneagram is even more unknown than MBTI and Socionics as I am only able to eliminate type 2 (I have taken several tests).
I also took a Jungian Cognitive Function Quiz online and found that my most developed to least developed functions are Ti 90%, Ne 90%, Ni 80%, Fi 80%, Te 55%, Si 40%, Fe 35%, and Se 30%.
I could be getting my functions wrong here but, I think I use Ni pretty often; in fact, just three hours ago me and my friend were leaving my other friend's house and I experienced something like a vibe and I almost instinctively asked my friend if he had his car keys, which he checked to see if he had but evidently didn't; he told me he had left them on the table inside my other friend's house and was surprised I caught that he left them. I'm also one of those people who can instantly figure what a movie or TV show is going to do next, i.e. if a main character is going to be hurt or dissecting complex plot twists before they happen. Consequently I feel myself using Ne as well, but only during social situations. In conversation I connect the dots from various ideas that were discussed, tying them together with brutal sarcasm and humorous wit, and this causes me to seem extremely gregarious in conversation because I'm constantly juggling ideas around and making witty jokes.
On MBTI, I always score E/I within 5 points of each other, most commonly 2-3 points apart, and I suspect that I am either an incredibly rational and intellectual INFJ, an INTP, an ENTP, or a procrastinating and spastic INTJ.
