I think it's the xNFP ability to empathize. The Ne intuition, plus the Fi/Te, naturally reads things that other types usually miss.
Most see INTJs as impassive, imperturbable. They notice that we aren't interacting with anyone. If they're more perceptive, they notice that we have an intense, but low-key presence that is very still, waiting for something that may never happen.
But xNFPs, and especially ENFPs, wonder what's behind the mask, and because they understand such things in terms of their Fi, their guesses and speculations are more often not correct.
Then, especially the ENFPs, due to their extroversion, walk up to the INTJ and interact with the INTJ using their speculation of the INTJ's inner self as the keystone ... and everything clicks.
This isn't a guaranteed reaction, one should note. Not all ENFPs nor all INTJs are capable of dealing with the other maturely.
But given that the two of them click, the main thing that the INTJ sees in the ENFP is a complete acceptance of the INTJ as is. (Hence the need for maturity ... accepting an immature INTJ can be bad.) Both Ni-dom types have as one of their chief complaints is that no one understands them. Ni comes from left field. The Ne-dom ENFPs read Ni material pretty much as it was intended, with very few, if any, misunderstandings. It is the Ni-dom fear of misunderstanding that makes us reluctant to open up to others. By removing that fear of misunderstanding, ENFPs (and to a lesser degree INFPs) get INTJs to open up in ways that few others ever see.
I get this a lot, from my INTJ, that I *actually* understand him, where most people do not.
Granted, I don't understand all aspects of him, but I read both his implicit and explicit signals/signs well.
What, hmmm, worries me about your above statement is this part, "the main thing that the INTJ sees in the ENFP is a complete acceptance of the INTJ as is."
That's all?
Acceptance?
No mutual exploration?
No mutually found depths of life, and meaning?
SillySapienne wants more from her mate than her mate exclusively wanting her understanding and acceptance.
I give that shit out like candy, granted, INTJs are a bit more complex than your average Joe, but still, that's all you want from us?!!?
Really???!!?
And, once again, this might be due to my enneagram, but I feel misunderstood and freakish all the damn time.
Yes, I have the ability and facility to connect with many life forms, and the universe itself, but still, on a human, existential level, I feel quite unique to a negative, lonely extent.
I was not built like other girls, my desires are vast, varied, and deep.
And, I think what makes me fall in love with people is their ability to "get it", in general, and more specifically, their ability, which is rare, to get me. :blushing:
