I was reading in this thread that it is believed that people are born with their types set, but I'm curious if any of you believe that how you are raised has anything to do with it.
I ask because an MBTI test I recently took typed me as an ISTP instead of ISTJ. (When I have taken the tests elsewhere, I usually score about 52% Judging, 48% Perceiving, so this isn't exactly impossible) According to my mother and my best guesses, it seems likely that my brother is an ENTJ, my dad is an ExTJ (Mom thinks S, I think N), and my mom is an INFJ.
Therefore, if I really am a P, is it possible that I exhibit several J functions due to my upbringing, which is strongly J dominated? Am I perhaps missing out on my natural preference because I didn't have any Ps to guide me growing up?
So I guess what it comes down to is: are we born with one type, and then it is modified based on how one is raised, or will the prevailing type shine through regardless?
