My function program, the one I just updated, says you are an ISFP. You should read up on ISFP.
ISFP is a total mismatch with me. Actually I discarded S from the very beginning. INFP sounds more suitable than ISFP anyway.
Yup I'm a dreamer and idealist, so I can't see how the practical and grounded S fits me. If I sound practical, it is because I learned it from other people.
I don't know which part of me makes me sounds like a F. I don't say I'm not because in the first moment I knew MBTI, I chose F too. But maybe because it sounds great to be a gentle girl, decent lady, whatever. Or because I love arts, and artists are supposed to be F.
Wait, can childhood be a good reference on what you are?
I just remember I was told that I cannot control my temper, which in my opinion I was just excited. I was told that I was detached and always ran away from groups and did things alone. I was told that I should talk in a more subtle way but I thought, why bother as long as I wasn't lying? But I remember occasional tantrums tho.
J (Judging) means prefer having things done, making a decision. P (Perceiving) means prefer leaving options open, delaying decision making as late as possible.
So I suppose a J will have their decision making function as their dominant function, while P will have their information-gathering function as their dominant function.
This is applicable to Extroverts. But why things are opposite for Introverts?
It's just the way J and P are defined. They signify what kind of function is your first extroverted function. If they had defined it differently (switched for introverts), it's not like any information is gained.
It's just an arbitrary definition for signifying function usage. That is all.
