I copied this for someone else, then realized I wanted to post it here; then on my Visitor's Page, and blog it, too. I get so tired sometimes of being mistaken for an extravert, but more so as some other introvert, especially sensor. If I were one, no problem; but as I'm not, here for myself, and anyone who can relate:
Most likely to mistype as: ENFJ [for me, only in person, "maybe" by some who know something about MBTI; otherwise I just get "tough"; "smart"; "do your own thing" and stuff like that, including "sweet"--I'll accept some of the adjectives but not the wrong type as sealed in cement.]
Why the mistype happens:
Extroverted feeling feeds off the emotions of others, which means that INFJs require a great deal of social time in order to remain emotionally stable.
This type is highly likely to appear extroverted to those around them, as they are most animated and enthusiastic when they are in the company of others. * Most INFJs are assumed to be ENFJs by others upon first meeting them.
*This is also an important distinction between INFJ and INFP types, as they often mistype as one another.
INFJs glean energy from almost any form of positive social interaction, even the ‘niceties’ of small talk, as their extroverted feeling is highly in tune with social conventions/norms. [True for me as long as it doesn't go on too long; if it does, I get irritated; I've been known to walk away and leave my ESFj husband to deal with people as he really digs it: Movies, sports, whatever--he's game.]
INFPs on the other hand, are only energized by social interaction if it plays on their extroverted intuition – for example, if they are brainstorming ideas with someone or discussing a philosophical issue. The INFJ certainly prefers discussing the ‘big picture issues’ if given the choice, but they’re infinitely more comfortable with small talk than their INFP cousin.
I'm an exceptional brainstormer "and" I am, without question, an INFJ.
I was mistyped as INTJ for seven years; then this past year I got a lot of INTP. And some INFP.
But I am INFJ, and so many people think I am an extravert--sometimes on line; so many off-line. The people who mistake me for extravert do not do necessary research--a task I have always enjoyed.
All done, for now.
