I was chatting over on another MBTI forum and someone mentioned that ISFP, not ESFJ, was the true antithesis to INTP.
I realized at least in terms of pure function use, this is correct.
ESFJ = Fe + Si + Ne + Ti
INTP = Ti + Ne + Si + Fe
ISFP = Fi + Se + Ni + Te
And it sort of fits with what I've said in the past (and in terms of total shadow function theory), where Fi (and NOT Fe) to me is the worst enemy of Ti because it operates in the exact same sphere as Ti is trying to, but with a completely different set of priorities.
So for the Ti person, the Fe neighbor might be annoying but they live in the house next door and like to apply their rules to the gardens outside, and so you can accommodate the way they do things, maybe even apply them to your own garden (even if your house inside is run by Ti), because they are applying different rules but in a different sphere than you are.
However, the Fi person who lives in the same bedroom and house as you is using a completely different set of standards and yet still operating in exactly the same areas as you're trying to. You *will* have disagreement now... and even direct interference if neither of you can back down.
Which made me ponder: ESFJs used to annoy me in terms of working style, but now I find them a lot of fun and I connect very easily with them. When young, they come off as stubborn and inflexible, but as adults they actually seem to sense the prevailing social attitudes and change with it based on the current needs.
ISFPs, meanwhile, were usually okay in terms of working style and we had fun together... but on the few occasions I've had to bump heads with them, it was almost impossible to get any sort of compromise. Basically, the Fi values (fueled by Se) are conflicting direction with my Ti values (fueled by Ne). Because we are both I, we'd simply avoid having conflicts and avoid the controversial topic, so as to have a happy comfortable fun time together. But now that I've had a few instances where the ISFP was mad at me for violating their values, we had a lot of distance -- they weren't interested in or able to promote a rational argument to change my mind, and I could not just accommodate their values that I thought were wrong, and so now we had an issue.
Does anyone else have thoughts on this?
