*throws big wrench into conversation just to be amusing*
Are you an INTP?
LOL I'm still not sure! It seems most likely. Others who know me well assume I'm an INTP and likewise are surprised to hear I've tested as an INFP before. I didn't think I was an INTP until an INTJ friend suggested I take a second look at my old, early-college MBTI results.
This INTJ friend cited a great deal of information about why he didn't get the INFP vibe, and his reasons for thinking INTP rang much truer for me than the INFP descriptions did. Even back then, I answered about 60% feeling and 40% thinking preference and my job preferences indicated both "investigative" and "artistic" occupations as my main interests.
Now that I've lived on my own for several years, I usually test as an INTP on online tests, but I'll still get an INFP now and then if I'm in a certain mood.
I recently took this test --->

I've also tested as INTJ (not even remotely possible). But it seems most likely that I was born an INTP and was artificially rearranged by my environment into INFPness for as long as I had to be dependent on others for my survival.
In early adolescence, I was really nerdy (lost interest in everything aside from drawing comic books) and got picked on all the time. So I was pulled out of school and isolated in an extreme religious setting. I got completely exhausted by all the screaming matches and other unnecessary punishments when I'd argue science versus religion, and some of the religious kids were actually quite nice to me. It was a real relief.
I learned to appreciate their quest for authenticity and something beyond what one can see, and I learned how to survive that setting.
It seems that feeling as though one was born an atheist seems to be related to having a "rational," type of personality, which explains a lot about why I slowly but surely gravitated back as far away from religion as possible into a comfortable relationship with critical thinking and skepticism. Now that my former high school/early college friends and I have all gone our separate ways, my former INF friends and I have less and less and less in common. They can't stand my newly deepened interests in math, science, and non-religious philosophy. They also think I'm very strange to dream about getting a PhD when they mainly just want deep, close, meaningful relationships, etc.
I think the frequently-off typing that INTPs often engage in might be due to the need to constantly question, rethink and reevaluate. I'll never be certain that I'm any type at all. I'm very skeptical of psychology in general.
