hm.... if there's any correlation between my personality and background, it's that I'm extraordinarily stubborn. I've gotten nothing but hassle for INTP characteristics from parents... and they were there from a young age, alright. I've been stubbornly individualistic from day 1... I was watching some home movies this summer, and my brother (4 years older) kept trying to get a 2-3ish year old "me" to play with him, and I kept getting bored and walking around the yard to look at things on my own. My parents told me I actually taught myself how to read, occasionally asking my brother "and what sound does ___ make?" every time I forgot one. I know I could multiply and divide before school, too, because my dad explained the idea of division once and then asked me two questions... first "what's 100 divided by 4?" and I immediately answered "25." When he asked me how I knew, I said "4 quarters in a dollar!" So, thinking I didn't really get it, asked what 100 divided by 5 was. I sat there for "a while" (not sure how long) and said with impatience "20. ...[little hesitation]... dad, I get it already."
If anything actually did mold me... it must be the core of stubbornness. Supposedly my dad tried to teach me what hot was by heating up a cup to warm, putting my hand near it, and saying "hot," (which seems like a very sensing thing to do, to me). lol but when I was outside and he was grilling something, and he said "this grill is hot" the first time... contrary to his hopes, I distinctly remember thinking "how hot could something be?" and touching it anyway . haha that one backfired quite a bit.... "warm" feels good, "hot" does not. Maybe that pushed me away from learning by Sensing.
The same goes for Judging. Both my parents are SJs, and they equated J-ness (organization, discipline, planning) with maturity. Every time I acted like a P, they would get upset. It also kept me away from quite a few sleepovers and having out with friends, because they needed (in my opinion) obscene amounts of forewarning to even have a chance of letting me do anything. Perhaps the frustration turned me Perceiving.
Thinking was another one... you'd think with two STJ parents that wouldn't be a problem, but Ti and Te are much different. A pronounced Te they would have been thrilled with... since it's a Judging function extroverted. A pronounced Ti made them think I was neurotic or at least weird. All the little rules and games I used to come up with that lead to twitching and odd motions and habits (the details of which are getting too far from the relevance of the thread) just worried them to the point where they tried, gently, to push me to go see a doctor to make sure there was nothing wrong with my brain... but I stubbornly refused.
The I/E, on the other hand, they never pushed me either way. Well... only when I started to turn what looked "unhealthily" introverted did they start to get concerned about that too (I used to play with kids fine when I was younger. Then a bunch of stuff happened and I stopped, so they only tried to push extroversion because of the change--which was, at least, a legitimate concern).
As for the strong F-side... that's largely due to my brother and friends. As much as the STJ parents grated against me, the ENFP brother took it all much harder (and fought back quite a bit more, too). Try telling an ENFP to plan and think instead of deciding by instinct.... see how that works out for you. Let them go by their instincts, and it's amazing how much better their decisions turn out to be. I think that watching that opened my eyes to subjectivity a good deal, how opposite decision making can land you at the same places. It just took a solid 16 years for me to get to that point .
So to answer your question... if everything in my past is what made me who I am now, then I am, at the core, one extremely stubborn person. *shrug*.... doesn't sound unreasonable to me.
