How does having 6 as a core influence an ENFP? Does it make them prone to mistype as INFPs (due to seemly having more Si) or even STJs? And what's the influence of a wing 5 vs a wing 7? Lastly I've read the 6 chapter in your book and I've noticed you didn't distinguish between phobic and couter phobics 6s. Is it because you don't think this concept is real (some people say all 6s can be phobic and counter phobic depending on the circumstance)?
Too bad you can't just watch me for a couple of days; that would answer all your questions about ENFP 6s, lol. And I'm too tired to write a 12k word analysis on what it's like, not that I wouldn't like to, since I love nothing more than talking about myself at length.
In short? I doubt my assumptions but never my ethics; I am often right about other people but may ignore my own instincts in favor of being more 'fair' or there being 600 different reasons why they did something than I have thought of yet; I will ask myself if I have a 'right' to feel what I am feeling or if I should get over myself; I have spirals in which when something is out of my control, I will start thinking of endless ways it will go wrong and be bad, and trying to find solutions (Ne/Te) without being able to land on anything; people often tell me that I think too fast for them to keep up with me, that I change topics too rapidly, and that I change my mind and second-guess myself instantly (I do the latter a lot less than I used to, since finding out that's a 6 trait and deciding I hate it about myself and intended to stop). I am in a weird place between respect for tradition and total disrespect for it; my spiritual beliefs do not fit in anywhere and almost no one shares them, for example. I get weird looks for being such a walking contradiction and so inconsistent, for holding views that to other people, seemingly conflict, but make sense to me. I am extremely sensitive toward other people, aware of not wanting to offend them, but unable to read their feelings; I intensely monitor their face and try to read into it, to assume whether they are having fun, are bored, want me to do something else, etc.
Yes, there are endless typing spirals; I still regularly demand to know of ChatGPT what MBTI type it sees me as (ENFP 6w7, 9 times out of 10, lol) because I don't want to bother anyone else with my inability to land. Ne never stops reframing myself, and 6 never stops fearing I may be a fraud. In answer to your question, yes, my hesitancy to speak without thinking, my wanting to reflect before I act, etc., does make me seem more introverted. I find it exhausting to be out in the world, because I am hyper-attuned to my environment in a 6ish way -- watching people, being careful while driving, feeling over-stimulated in a busy store. A few people have typed me INFP based off typing videos, because I thought about things carefully and was not going off in 100 directions all at once. 6s are pretty linear, way more than 7s or 5s. It gives me some 'direction' and if something goes wrong, I can't think about anything else until it's resolved.
I am a 6w7, so I do reach a point where despite my self-doubt, I go "screw it, let's do this and learn as we go." I will get tired of questioning and thinking in multiple or opposite directions and just pick something to have a direction, then revise on the fly. 6w5s would be even more withdrawn, hesitant to act, and never feeling like they are ready. I literally started this blog knowing almost nothing about MBTI, but I thought "doesn't seem hard, I can learn as I go," and along the way I became an expert because I never stopped learning and applying, but I know other 6w5s who go "I want to feel ready before I do something like that." Not sure if it stalls out an ENFP forever, though, the way it does introverts.
I don't believe any type has a counter-type, and that includes 6s. I think people lean more phobic or counter-phobic, but that they can still move between the two on a daily basis, depending on their comfort levels. I've had moments where I was totally intimidated and kept my head down, and other moments when I totally challenged authority, and realized in hindsight that was a bloody stupid thing to do. I contradicted a cop over a traffic ticket :P but I shy away from most online arguments.
Same goes for other 6s I know. Some of them confront what they are afraid of one minute, and avoid it the next. 6s aren't great at calculating when it's the best time to put up or shut up sometimes, lol. I am semi-aggressive in a work environment (low Te has a "is everyone stupid today, why the hell can't you just answer me?" when stressed bluntness) but fairly accommodating and passive with my friends.
I will say that now that I'm older, I'm a lot less insecure, I put up with a lot less bullshit, and I have a lot more faith in myself. Part of that is natural aging and part of it is growing through my 6-ness for the last 12 years. I can look back and see steady, massive changes over the last decade, and I feel good about that. Beats being neurotic and insecure!
