INTJ and ENTP
INTJ wants the plan to survive contact with the facts. ENTP argues for sport, and often improves the idea while doing it. Put them on a problem that is not finished yet and they will stay up. Put them in a meeting that is only there to be seen, and both of them will try to leave, by different doors.
The difficult part is that ENTP's teasing is affection, and INTJ hears an unfinished objection. ENTP likes the first draft of a new thing. INTJ likes a standard the draft has not met. If you are the pair, name which conversation is play and which one is a decision. ENTP should say the plain sentence too. INTJ should not treat every spark as a commitment to rebuild the plan.
ENTP is the start of the project and does better paired with someone who finishes. INTJ will finish, if the constraints were real and not a moving target. Agree the constraints once, in writing, and then let the argument be about the idea rather than about whether anyone is taking it seriously.
