Maybe here's the first problem.
Selftyping hasn't got anything to do with self awarenes, but with comparing yourself with groups.
example, I once asked an IEI-ni gilfriend of mine whether she saw herself as an introvert or extravert (after explaining roughly what that meant.)
She said 'a bit of both'.
After I said, well do you look most like your gilfriend x (an introvert) or your girlfriend y (an extravert). She immediately said, oh I'm more like x.
It's easyer when you compare yourself to others, then to describe yourself.
