First time I took the tests? I got something of an INFX. I went through INFP>ISFP (Members here said I was sort of ISFP ish)>INFJ.
I went with INFP for all intensive purposes in the beginning. Of course, I didn't really care too much about it besides the fact that taking the test was part of a class assignment.
There are still people here who think I'm an INFP (@Elfboy), and there is even some who think that I am outside of those three types, but I think it is because I've stuck with INFP the longest so I have formed some conceptions on how INFPs "act."
So a little bit of both? From all these years I've been messing around with MBTI, it seems a few of them like to ascribe the function orders in certain timelines. During those timelines, people tend to start developing their functions to see what works and what doesn't. What doesn't work obviously gets thrown out and what "doesn't work anymore" gets thrown out to be replaced.
When I first took the test was certainly different from how I ascribe myself now.
