Okay, I need someone to clear up a few questions for me about the plus and minus version of socionics, you know, with -Se and +Se, etc. So, I get that it can be useful insofar as it basically denotes which other function the IM in question is blocked with. But after that I really don't get it, so I have questions.
1) Why + and - as the symbols? What is the rule governing which Se (blocked with Ti or blocked with Fi) is + and which one is -? Or are the symbols just arbitrary, and it would be just as easy to label it *Se and ^Se?
2) What is the deal with one's superid functions being different + and - than one's dual's ego functions? That is, when I tried to read up a little on the plus-and-minus-socionics, I was very confused by the fact that IEI superid is, I think, +Se and -Ti, whereas SLE ego is, I think, -Se and +Ti. What does that signify/mean/imply?
3) How do I know how to assign + and -? Like, how would I figure out if it's Beta Ni is + and Gamma Ni is -, or Beta Ni is - and Gamma Ni is +?
