I made a fairly discombobulated post on here a while back which never went anywhere, then I gave up on this whole MBTI thing, and now I'm giving it another shot, trying to type myself and hopefully being more coherent in the process. Feel free to reference my other post, but this one will be much more lucid and organized.
So: long story short, I am INxx, and whenever I take any test, the last two letters are neck-and-neck. By answering a single question differently, I could come out as F vs T or vise versa, and the same goes for P and J. The only exception to this is that on the IDRlabs test (formerly CelebrityTypes), I come out with a strong J.
As far as the dichotomies go, I really feel split between T and F, and for most of my life I have been much more stereotypically P than J. Especially in contrast to my family (mom, dad and sister are all SJs), I am chronically late, messy, disorganized, absent-minded, forgetful, and have a long history of procrastination. My default mode is to put things off as long as possible, and to make any decisions as late as possible.
As far as the cognitive functions go, the ones I most strongly relate to are Ni and Ti. I've made similar posts on other forums, and when I've described myself, the vast majority of people tell me I sound like an Ni dominant. From the reading I've done, Ni absolutely fits me. However, Ti fits me just as much, and I also strongly relate to Ne. I would more easily accept INxJ if it weren't for the fact that I am SO stereotypically P. I've been working on overcoming this for my whole adult life, trying to become more organized, scheduled, time-conscious, decisive, etc., and have been largely successful, but it definitely goes against my nature.
I were to list the functions I relate to most strongly, it would probably go Ni -> Ne -> Ti -> Fe -> Fi -> Te -> Se -> Si. I have absolutely no grasp of Si and actually react quite violently against it. My mother is an ISFJ and we are just such opposites.
I am almost positive I am Ti/Fe rather than Te/Fi. I'm open to differing opinions on this, but I'll stick with this as a given for now, unless the conversation goes in the direction of questioning this.
So, I'm down to INTP or INFJ. If I'm an INTP, I also use quite a bit of Ni, and my Fe is relatively well-developed. If I'm an INFJ, I have very malnourished Fe, abnormally high Ti, and strong use of Ne. Basically, I feel as if I relate strongly to both types.
Rather than going into a long-winded description of myself, I'm hoping that you all can ask me specific questions that might clarify my type, as sort of a dialogue. What should I be asking myself to determine between these two types? What further information could I give to help clarify things?
