I may have come across as harsh in the thread, but that's basically because I was pointing out the faults of the INTJ quite exclusively. Can the types help eachother? That is really up to the INTJ. If they continue to see us as threats to their egos (they can be very ego-driven if left unchecked) we really can't do anything for them. If they however were to develop the playful attitude to their surroundings that we. the INTP, have, not taking things personal, we could be great assets to one another. We could be the depth-perception of the thought. I however have not been successful in reaching this harmony with my friend, but only simulated it by posing scenarios and so on, which is to say impersonal matters. They have great abilities buried in them, and I think we're the only type that can really pull those out of them.
