MBTI depends on Jung's personality type theory. Jung's ideas on personality are actually quite interesting and involve a lot of nuance. If you go and read Psychologial Types, you'll quickly realize that Jung developed his notions regarding personality as a tool for literary criticism. That is, to have a way to explain why authors, throughout history, took opposite stances on issues. For example, he begins the book by interpreting the Trinitarian and Christological debates at the dawn of Christianity. My takeaway is that Jung's typology is less of a science than it is a philosophy of the psyche, or even a philosophy on how the psyche expresses itself, and thus belongs more in the domain of the humanities. I like MBTI as a shortcut to talk about Jung's theories. As a scientific tool, MBTI is obviously extremely blunt. Testing for your MBTI type is therefore not a very good idea, IMO. As far as I can tell, many people who really are into MBTI will rather try to "type" you in a guided conversation than you merely taking a test. This is much more in the spirit of analytical psychology anyhwow.
