Okay so I am definitely FP, both in terms of the four dichotomies and function theory. I am about as Fi/Te as it gets, and usually on four dichotomy tests my highest is F or P, with E/I being very sketchy (goes back and forth). I get N on most four dichotomies, but now don't trust their wording, as people can think they're N just because they have imagination or like to read, which is a totally misleading thing. I have gotten ESFP or ISFP on a test here and there.
I don't want to hear your arguments for why I might be ENFJ or ISFJ, because honestly, I am not an Fe/Ti type, I'm just not...and I'm not even at all "J" in the Keirsey sense, and I say this with complete confidence having read Please Understand Me II, and suprisingly finding myself identifying with parts of NF and SP almost equally.
Opinionated or assertive =/= J. But it could equal Se.
I just want to take a vote to see forum perceptions.
