I haven't taken the temperament test for years, but still "self-identify" as INTJ, and believe that it is my core. In another thread (perhaps the comment thread to the ERE personality blog post), someone wise said that with personal growth and experience (read: years of struggle in the universe) comes a balancing of personality. I recall something in the temperament literature about "X" being used when one tests 5/5 in a category. e.g. XNTJ would be someone who scored 5x E and 5x I of the 10 questions. So, would the ideal (for us here) be someone who started life as a "natural" INTJ, but who has learned to *operate* as an XXXX (4X?) when interfacing with the universe? ;-\
Back to this thread, I wanted to share what several mechanisms I have developed to facilitate INTJ-to-Universe communication, on my road to "4X":
* unfortunately, one must embrace some temporary pretense for the purposes of "getting in" to a particular conversation -- the good news is that it's just an intentional mechanism and it does not infect one's inner INTJ core: when you know you are right, you *must pretend* that you do not believe that you are absolutely right, e.g. "That's a strong point. It's possible that you are right and that I am wrong, but for the sake of this little argument, let's consider what the world would look like if I were right, and then compare that world to this world and get a sense of whether it's possible, or maybe probable, that I am right." That's actually a little more strongly worded that I pull off for real. There is more to it than the words; a modest demeanor is key, modest but still with a laser focus on the facts and the direction of the discourse. This is a modified form of "The Colombo". Read the 2nd paragraph here, and if you understand this, you can perhaps see how this applies to INTJ life:
* you *must not dismiss* any input from others! this is not just a matter of politeness, it's a matter of approaching the Universe as if there is always something to learn -- there may not always be something to learn, but that can only be ascertained after a moderate level of investigation. In a social situation, find some little quantum of interest in some little corner of someone's remark, and drill down as hard as you possibly cannot without crossing the creepiness / insane boundary (that balance is a different skill). You asking the question endears you to those around you. Quite often, I have found that I really can learn something useful from someone whom I thought I could not (and would not wish to) learn anything. The connection won't be on the order of INTJ-to-INTJ conversational serendipity, but it often feels good to have put in a strong effort on something social, even if the yield is not retirement portfolio ready.
