From Purple Giraffe:
Being a "J" personality doesn't make one more or less inclined than a "P" personality to want their way. It is simply a matter of interpreting the world. Whereas, Perceivers tend to delay making a final assessement of the situation to gather the widest variety of facts about the situation, Judgers will make come to a hypothesis and try to determine if the facts support that hypothesis. Therefore, it isn't that one wants to be right more but that they have different ways of interpreting their environment.
True. The INTP prefers to wait and gather in ALL the facts, and weigh up ALL the possible explanations, until he is sure. But for any scientific theoriest, that can take decades. In the meantime, INTPs remain in an unsure "flux mode", where we are willing to go along with whatever the other person wants, because we don't have a clear view of what to do, either for or against anything. In addition, our Fe makes us want things to be harmonious, and that means that we really want to do whatever will allow everyone to get along. So if the ENFP wants to go to that party, and the INTP really doesn't feel like it, because it means being social, but doesn't have a very solid reason not to, then he'll agree, just to keep everything harmonious.
From Purple Giraffe:
As with the nature of INTPs "mirroring" the situation, would this not in and of itself likely prove problematic and eventually cause stagnation if not eventually worked out, because the INTP's chameleon nature would serve as more of a front then as an actual representation of the INTP? So what you could potentially end up with is a long stable relationship where the two don't necessarily know each other but think you do?
INTPs live in our own heads. We think of ourselves more like organic computers than anything else. No-one really understands us, all that much. Some people have a problem with that, and drop us well within 5 minutes of meeting us. The rest are OK with it. Surprisingly, most people prefer our company.
