I'm just curious. I personally was trying to explain this mess. My mom always remarks how similar I am to my father in personality When really we couldn't be more different (INTJ vs ESFP) and I knew that, but in general, what is it? The convenience of being able to diagnose traits into a box? Finding people similar to one's self in a world where no one seems to understand us?
So, what's your type, what attracts you about this stuff, and then for each type what is your theory?
