This is the second sorter of this type I have been to - both of them putting me pretty high on schizoid, though other things differ.
Thing is, having been active in computer-based classification, I know all too well you cannot get much yardage out of so few questions, AND anything a computer does needs a human operator for interpretation.
I would need to ask - is this trying to sort apples into Valencia, navel, and other orange categories? I have no idea to what extent schizoid is me. Need to look into it. But I would not put too much weight on this.
