INFX people are really complicated for no reason a lot of the time. If you look at other types, they get along in the world just fine and aren't complicated.
I think a lot depends on what a person wants from life, and expectations [ one's own and other peoples and "societies"]. Some people are innovators, others walk around in mini-skirts and go-go boots and say things like "I love starbucks! I'm so perky and popular!"
Perhaps I am jumping off from your post to something else that you didn't mean, but I'd say its important for people to both be able to 1) contribute what they can, and 2) to "adequately function" in society. People will obviously have different ideas of what it means to "adequately function" in society. As a person with an advanced science background let me try to give an example. There are LOTS of very smart scientists [and engineers] out there with great ideas that would push technology and the like. But, and here is the big but, LOTS of them suck so much at "communicating" that they aren't able to convince someone else to support/fund their research. So nothing happens until those scientists [or engineers] learn how to write/talk/communicate in a way that will mean something to the non-scientists to approve and/or fund science/engineering research. And just so no one tries to complain that "Scott is being mean to INTJ/INT's/scientists/engineers again", let me point out that I have talked about this topic with several people in my professional career and they have all agreed and said that they had seen such sorts of people "many times."
I think a lot of interactions in "society" require very little depth. For example, going to starbucks to get a cup of coffee doesn't require any detailed psychological evaluation or you proving that you thoroughly understand multivariate calculus or any deep heartfelt conversations about your feelings.
The trick is to break these traits and become normal. But a lot of people won't do that. I don't see how being complicated, overly emotional and hyper sensitive are good traits.
Complicated people are probably multi-faceted, which might mean they are good at lots of different things. I think the issue is "complicated" something that lets you bring extra skills/assets/abilities to the table, or something that makes you a pain for others at the table to deal with. Really, do we want 1-dimensional people or to deal with them?
"OMG Paris Hilton is my favorite person, I want to grow up to be JUST like her"
Overly emotional, I guess it depends on what you mean by "overly", but if I think of people that volunteer with animals, or children, or foster children I'll bet many of them could be described as "overly emotional." Also, I'll bet that lots of people that are very nurturing could also be described as "overly emotional". Maybe you are referring to "emotional theatrics" or people who get thrown around by the whims of their emotions? Don''t those kinda people make good actors and performers though???
Hyper sensitive, I think many of my comments about overly emotional apply here as well.
I still may have missed what you meant though???
