Veeery interesting. This person - X - has tested ESFP, ENFP, ESTP, INTP and ENTP too!!!
To begin with, X is a colleague of mine. I have known X for 6-7 years now and I am yet to figure out what type she is!
I am fairly sure she's an extravert, she's one of the most popular persons in my class; she tries to get along with everybody and she pulls it off, she's like Switzerland, fairly neutral, but appreciated by everybody.
She is a grade A student and she gets pretty emotional about her grades. I mean, straight As. But straight straight! Her GPA was 10 out of 10 for years. When she first got a C in high school, her parents came by to talk with the teacher. And voila, it turned to an A.
Whenever she got less than A, she concealed her frustration from everybody, except her dear ones. Once, it happened that a teacher scolded her for having an ugly notebook and a messy, disorganised writing. So, by the next day, the entire notebook had been re-wrote with beautiful caligraphy. The teacher eventually was impressed by her tenacity and gave her an A for the effort solely.
She was the one to stay whenever all the people in our class decided to "skip" some classes. She would go, pretending to leave like everybody did, only to return after. Or she didn't even bother to go. If she left, she'd throw a fit, making all of us feel guilty of making her leave; of course, this wouldn't happen in front of the entire class.
She remained neutral in every situation, even when her friends were involved, just to keep herself in the safezone. She'd avoid to reveal her true beliefs to people, but to her friends. She is in a rush to please people, especially teachers.
Even she is the teachers' favourite, she is very smart and industrious and most of the time well deserves her grades. She is willing to study at whatever subject when needed.
She's a highly creative person and she has a sense of fashion. She surely dresses feel good, to look good and to be different - in a good way. She plays guitar and has put a lot of hardwork into this too, I might she's very determined.
She often underestimates herself intelectually speaking, especially in comparison with her boyfriend. However, she takes up the role of organizer when in a team or project, but her leadership skills are not very good. She is kind of orderly, not too much, but surely more than me!\\ Her IQ is of around 140.
She's interested in different kind of subjects: computer science, math, but english and french too!
She's quite sexually uninhibited and has no reserve in talking about it to her friends. She was the first in our group (of girls, duh!) to have a boyfriend, to kiss a boy etcaetera and she has had many relationships. She's very fun to hang around with and she's most likely to honor an appointment when she says she will.
She is not very earthy, most of the time not being aware of real consequences of actions, facts etc. She is idealistic sometimes (in theory) but when it comes to the practical side, she'll see her interest. She can trick herself into believing what is more comfortable, rather than the more or less bitter truth.
She is easily manipulated by her INFP (which I deeply suspect of being INTJ!!!) boyfriend, seldomly she's aware of it and just lets it happen.
I have never heard her using a bad word(e.g. "f*ck") in all of her life. The harshest swearing she ever said was the equivalent of "what the hell".
My guess is that she has a strong J component altought at whatever test she took she was P. I have no clue aboit N/S or T/F. So please, members of TypologyCentral, enlighten me!
