What do you say about co-operation of iNFJ and eNTP? Could it work? What could be the possible problems? What would be the benefits? Any ideas?
tl;dr: refer to phobik's post above.
It sounds like you mean in a team situation, such as in a work or study environment. in which case, yes, co-operation between INFJs and ENTPs can be
theoretically wonderful, Ne and Ni are extremely productive in brainstorming, Fe flattered by Ti is wonderful in understanding how can something be perceived and understood and is a great tool for extracting the social dynamics of a group, Ti flattered by Fe is a pretty good problem solving tool to see what can be done with the ideas from the Ni/Ne brainstorm and the information at hand, and to break down any problem to manageable bits.
I say theoretically, because there are likely problems along the way that can cause a lot of tension.
first of all: space. E vs. I
extroverts in general do not intuitively understand the idea of "needing space", i mean sure i am a large guy and probably consume a large a sizable agricultural area within this planet, but other people are allowed to be there (to work the farms). i do need space for myself on occasions, but i don't need space away from people in order to contemplate things. it took me a very long time to figure out why introverts start - what appeared to me - to be acting insane, as if after some point in a conversation your mere presence is pushing them with their back against the wall (and not in the sexy way).
a larger question is the question of questioning:
when the ENTP's Ti>Fe pushes the INFJ into Ni-Ti analysis-paralysis.
xxTPs swims in doubt, because doubt is very much an element of who we are, the way Ti (for both NTPs and STPs), is almost like a question generator in the back of your head, and so we live in a constant state of doubt about almost everything. the cooping mechanism for that is an
over confidence in one's competence. we are incredibly used to making the wrong gambles, and so become over confident in our ability to deal with whatever consequences come. to quote a battler who never quite bothered to exist,
"Why do we fall? So we can learn to pick ourselves up".
xNxJs do not function very well in states of doubt. Not intellectually mind you, many of them like the idea of doubt, but to quote Douglas Adams,
“We demand rigidly defined areas of doubt and uncertainty!â€. in action,
'analysis paralysis' seems to be a genuine problem for them. the cooping mechanism for that is an
overconfidence in one's understanding.
while this might seem like a good thing, and often it is when facing external challenges, it also creates problems in long term dynamics, because while initially their cooperation might be facing an external subject, more and more, their dynamic will include facing each other, and the xNFJ can find themselves flooded in the doubt generated by the xxTP, pushing them into Ni-Ti loops, a state in which they find themselves unable to properly function or make decisions.
this leads to another problem: objectivity.
when the INFJ's Fe>Ti pushes the ENTP into a Ti-Si grinding-water.
as said before, INFJs Ni-Fe can be wonderful at figuring out the perception of things, what something mean to people, what things look like. but many of the less mature ones, that is all that there is, that is what compels them, the part that matters to them, how something appears to be is what something is. this leads them into quite the life long struggle with the desire for something genuine, and the ability to define and identify what something genuine would look like. you know the saying "clothes make the person"? replace "clothes" with "an intricate understanding of the sociological meanings, context and innuendo" and you pretty much got it. the desired need for resolution can make one quite comfortable in taking the appearance as it is, with no further inquiry.
ENTPs on the other hand, have an innate desire for the objective. while many of us might be subjective in our philosophy, Ti cringes at rational inconsistencies, desires to fix them, point them out, or alternatively make light of them so that the space-humor continuum can rest in peace. basically, in the end everything
has to come down to a leveled playing field we're all playing in, and we might as well call it "objective reality", because calling it T
he-iScream didn't sit well.
again, on the surface it looks like a perfect match, one to take care of this area and another to take care of that area, and sometimes it is, again, as long as what they face is external, but soon enough the realities they will face won't be merely the external challenges, but each other, and sooner or later, the xNFJ is going to make a decision, a conclusion about something whose rational basis smells very unsatisfying. for the xNFJ, that means no more inquiry, its a done deal, topic closed. for the NTP, no further inquiry means having to relay on past inquiries, it means going to our baby Si and asking it for help. except no matter how many questions you ask your memories, if no new information comes, your not going to get new answers. each question just leads to more inconsistencies, more hypocritical patterns found, more possible answers which lead to more questions... and there's no discovery to save you or guide you, because the information you have just sits there and degrades on it's neurological ass, and your mind just starts grinding water. the part of you that cares about the matter can't let go, because it can't reach anything to go to.
hypothetically, any two mature indeviduals can overcome such problems, and many others. practically, your talking about the tricksters who get their grove by 1up-manship (and asserting that we are better), and mystics aspiring to world peace by believing they are always right (so everyone else is wrong)... maturity becomes a scarce resource.
have you considered hiring SJs instead?
