Myers Briggs? I bet that it shows that everyone is different. Or, it isn't that (impossibly) refined and one could use it and lump people in multiple categories. Sure, that would be helpful, especially if there is really no choice about interaction.
But, everyone is different.
When we try too hard to lump people together, we need to look at some folks with, what is considered, serious disabilities. Some blind people live alone, take care of themselves, go on errands, make it to appointments. We admire people like that; I suspect because we can't imagine the skills that would take. Are those folks really more successful and happy than the person living entirely by the assistance of others?
The deaf have capital D people and small d people. The Deaf have a very developed subculture. The deaf often interact and live in the hearing world. There are hard of hearing people, plenty of them and losing hearing as we age is common. These people often learn how to get around okay with limited hearing. Is "getting around" enuf in life?
I don't like the feeling of being limited and that means I mostly act within my own "realm." Being alone in a crowd - absolutely, I know that feeling.

"Smile, because I really don't know what is going on." I'm enjoying growing olde because others are coming to expect me not to know what is going on. I was asked the other day if I was "4 20-friendly." Um, no. 's'okay.
I've always felt some relief when others can enjoy themselves without my involvement. However, I will wind down to absolutely nothing if I felt that someone or something didn't need me to take some action. Of course, everyone needs some rest and relaxation.
