I'm pretty sure I'm an ENTP and lately I've really been looking in depth into MBTI and Socionics and even told a bunch of my friends to see what type they were. Some were much more interested than others, and some even said that they can't be classified according to the tests.
To me, this personality stuff seems very relevant and has helped give me some perspective on the way I look at things and also on personal interactions, but some other people I know just acknowledge it because I bring it up, but don't really show interest in personality stuff.
Have any of you found that certain types are more interested in personality theory than others?
In general I've found more N's interested, but I had a really long, interesting conversation with an ESTJ about it who seemed very intrigued.
