As far as Introverted Thinking being so "objective" and "truthful", lets see what Carl Jung had to say about that:
Eat that, suckas!!!!!! :workout:
Introverted thinking is primarily oriented by the subjective factor....It does not lead from concrete experience back again to the object, but always to the subjective content. External facts are not the aim and origin of this thinking, though the introvert would often like to make his thinking appear so. It begins with the subject and leads back to the subject, far though it may range into the realm of actual reality....Facts are collected as evidence for a theory, never for their own sakes. (C. G. Jung, Psychological Types, 380.)
****EDIT: Matter of fact, I think that quote deserves a whole thread of it's own.
