Here's my two cents from an INFJ perspective:
"Because INFJs use Fe to relate to the outer world, they may seem more outgoing than they really are. Their personal approach and ability to find common ground with others combines with their intuitive need for innovation and alternative views, and they frequently find themselves in positions of authority. They may not seek leadership, but they are often elected by others to serve on boards and committees. People appreciate their ability to listen and to consider group feelings and values." - (Personality Type: A User's Manual)
My Personal Experience:
As far as leadership in the crowds? My friends probably do consider me the leader of our little circle, but I emit this silently through integrity, responsibility, and reliability. My friends have never called me in need of help and not received it.
I always end up being the leader in some form or fashion. I'm very reliable and easy going and I don't mind being the "servant leader", but most of the time people always end up taking me for granted. My senior year of high school I was the Vice President of NHS, but I ended up doing all the President's work too. She was praised by the Principal for all the hard work she did at our awards banquet... while I was the one that did it. My only problem with being a leader is that EVERY SINGLE TIME I NEVER GET ACKNOWLEDGED FOR THE WORK I DO WHILE OTHERS ALWAYS DO. Even for the tiniest efforts!
For example, in the Residence Hall at the University I go to I am a Sophomore Adviser (a step below Resident Assistants). I work the office during the week and one of the RAs regularly didn't have our Newsletter ready the day it was due. Who ended up doing it? ME. I took his messy newsletters (that represented Microsoft Publisher at its worst) and turned it into a very professional and smooth-looking product. I did this at least four or five times. No one ever thanked me. An RA at the beginning of this semester had to do the Newsletter (because the other RA forgot yet again) and she got so many kudos at our Staff Meeting for something that looked worse than the other RAs newsletters! (Which I didn't think was possible.) Mainly they were complimenting how quickly she adapted and completed it within 5 hours. I've had to do it in less than 2 hours before. Did I ever get Kudos? NEVER.
Another example would be how the Director gave another RA kudos for adding a glitter "swirl" at the bottom of our Banquet invitations (a fifth grader could have done it). However, I failed to get kudos for picking up the card stock used for the background, typing and printing the actual invitation, cutting the invitation out with the scissors that cut in patterns (which was a bitch because I am left handed), cutting the card stock into even blocks, and then gluing it all together. She added a tacky swirl and they acted like she was some kind of saint.
Yeah, so this definitely turned into a rant, but my experience has always been like this when it comes to leadership positions. After a while I always inevitably give up and stop giving my all to the position. Those who barely do anything get the praise for doing something and those who have done something all along are ignored. Sometimes I think I should just become a permanent flake.
If someone actually read all of this... then .
