I was wanting to discuss this sort of thing too. I have come out the MB as an INTP, by the way.
I agree with some of what's been said. I tend to find the conversation in such situations pretty difficult. To me, it's like there's a kind of social game being played. Perhaps few believe that what is being said and acted out is that 'genuine' but because everyone seems to be doing it, then each of us believes that the other people believe it is 'genuine' and so we have little choice but to conform.
There is the introvert v. extrovert difference as well. Perhaps the extrovert type is quite happy playing the social game and wants to play it, even is able to be more genuine within it, while the introvert not only isn't very good at playing it, but thinks it is a bad game also.
Personally, I'm becoming more and more reluctant to enagage in such social games. Even in one-to-one relationships with those who are closest I am not able to be genuine. I fear I would be rejected. Even on this forum I will not be genuine although moreso than in 'real' life and that is largely why I am here.
I feel I am rejected for who I am to some extent and so to survive in some genuine way I have started to reject those social situations that always seem to conform to the game of making out things are a certain way.
In terms of advice, it is hard to give because I don't know what you are trying to achieve, I have little success myself, and we are all coming from and going to somewhere slightly or greatly different from each other in our life experiences. But if someone were to try and advise me to learn to play the game, at the moment I'd want to tell them where to go.
That said, I'm quite happy to play the game of superficial relationships in superficial situations e.g. business transactions. What bothers me is when the people involved are meant to be important to me personally and I still have to play this BS game.
