What’s perplexing to Ni is that even though Ne may have seemed intrigued by, even highly enthusiastic over an Ni idea initially, Ne by nature tends to lack the theoretical staying power of Ni; it’s fleeting. This catches the Ni off-guard as it’s naturally expecting the kind of discernment and religious devotion that he himself exhibits as an introverted intuitive. The result can be Ni actually feeling betrayed, as if Ne is guilty of intellectual, or metaphysical, infidelity. Ni, having spent a lifetime carefully crafting and refining its paradigm, is horrified when Ne, like an unwitting consumer tossing back a $2,000 glass of Burgundy in a gulp or two, fails to really realize (let alone savor) what Ni has supplied. And before the Ne can even get the words, “thanks for the drink!” out, he’s already looking for the next vintage (or so it seems to Ni), because once Ne has gleaned the “basic” concept, it needs to find another new idea or theory. After all, how can Ne be certain that a given wine is the best one not having tried anything else?
For the Ne’s part, the initial encounter with an Ni’s philosophy has the appearance of something novel (since it’s likely the first time Ne is coming in contact with that theory.) Such apparent novelty implies that the Ni type is open to new theories and areas of conceptual exploration, much as the Ne is. Imagine the Ne’s surprise when he learns that the only theory that Ni is open to is his own, and that when confronted with new concepts from Ne, Ni isn’t going to be nearly as eager to entertain them as Ne was. So goes the common refrain from Ne types: “you’re so closed-minded!” or, “you’re just threatened by competing ideas!” Additional accusations may include decrying the Ni as dogmatic and hypocritical for dishing out its own perspectives without being able to receive others’ in turn.
Often, however, all that is needed is some space and time for each type to do some additional work within the functional stack, to consider one another’s type differences as well as their personal philosophies. The Ni type can’t be expected to show the same openness to a new theory that Ne would, nor can Ni expect the same commitment, “or closedness,” to a theory that Ni has. However, as Ni continues in its growth and development it will (albeit slowly) tweak and refine its paradigm to include those pieces of information that it has extracted from subconscious Se experience. In other words, if one of Ne’s proposed theories actually holds weight, Ni figures that it will eventually “discover it” for itself and incorporate it into the working Ni theory – a much more authentic way for an Ni to adopt an idea than by simply accepting it from without. The same is essentially true for Ne, except that it’s consciously collecting as many competing theories as possible from the outset so that it may work them through the remainder of the functional stack, through Si as well as the judging functions. And if an Ni theory is true, it too will be proven with time and experience.
If Ni can appreciate Ne’s need for exploration, trusting that Ne will return if, after tasting hundreds of vintages, he eventually realizes he’s found something really special in Ni’s insights, then a respectful and enjoyable relationship can occur. Conversely, if Ne uses its open-mindedness to understand the difficult position that Ni is in with respect to being able to accept a new theory from without, trusting that Ni is constantly refining its insights and learning to be open to experience so that its theorizing eventually becomes “all-inclusive,” these two types can continue sharing a particularly special rapport with one another as they each set about on the quest for knowledge and truth.
