PS to the rant below. I have always felt intrigued by Typology - knowing I 'was' one of Jung's Introverts in an Extravert culture helped early on.
I have studied a lot of ways of dividing us up. Personally I feel a little nervous about all the more recent 'illnesses' and 'syndromes' that we have 'discovered' (invented?) - even though some of them may seem helpful, too many of them appear to me as inventions of drug companies (and other people with vested interests) for me to feel comfortable with them. And labelling people seems always potentially dangerous - especially if you can get them to define themselves that way.
Uh-oh, I didn't mean to start again. After reading so many 'grids' I eventually ended up at Astrology, not for the 'hidden influence' part of the theory, but for the subtle and rather complex tool it represents for attempting to describe the range of 'styles' of humans, and the ways they approach the world. It has evolved over many centuries and several cultures, and for that reason alone should interest us - rather than the latest fad.
Having said that - check out this site about the XD38 personality, an extension of the Myers-Briggs model, itself an extension of Jung's stuff. Note: I don't recommend any of this.
And before you decide you 'are' an XD38, or think I claim to 'be' one I'd like to remind you (again) of the Forer or Barnum Effect.... and of E-Prime. Have fun! (and that 'is' an order!)
