I have heard it said that one's MBTI and Socionics type will generally differ.
This leads me to ask, what aspect of the personality are each of these systems measuring, and so how can you identify each side as distinct from the other? I assume that both systems are based in Jungian Cognitive Functions, but apply the analysis to a different side of the person.
On the other hand, you may believe that we only have one type and that MBTI type = Socionics type. If so, what makes you think this?
And lastly, if you do believe the 2 systems are looking at different things, are there other mutually valid ways of assigning Jungian type?
