I've often wondered why somebody is the type they are. Like, why am I an INFP? Why am I not ESTJ or ISTP?
My thoughts are:
1) Genetics: My father is INTP while my mother is INFJ. Therefore I believe it is natural that I be an INxx because both of my parents are. If I had siblings, one would probably be INTP, INFJ, INTJ, or, like myself, INFP.
2) Nurture, how you are raised I think can factor your personality type. I don't know how...but...maybe... :/
3) Choice. We simply choose to be a certain type of person because that personality is what we find attractive.
What do you guys think? Environmental, emotional or genetic factors? Or just pure coincidence?
