I disagree. The MBTI was devised by non-scientists based on the Jungian model of the psyche - a model with severe and inherent shortcomings and flaws. Nothing Jung posited was based on empirical evidence, his theory of mind was (and is) based on the previous work of Freud and Adler, among others and all discredited. The MBTI is simply a binary test for 4 values E or I, N or S, F or T, P or J. That's it. It CANNOT explain things like sociopathy, autism, depression or schizophrenia. It's SO unscientific at this juncture to be not much more advanced that phrenology. Furthermore, people with (what Jung et al termed) neuroses while on waiting lists for Jungian (and Freudian) psychoanalysis improved or recovered at exactly the same rate as those who actually received the "treatment". Everything about Jungian psychology and everything derived from it is severely flawed and should not be relied upon to reach any conclusion. The MBTI is one of those things. Jungian things are interesting only in the context of the history of psychology and psychiatry.
Full disclosure: I'm an RPN (Registered Psychiatric Nurse) and have studied and practiced psychotherapy and cognitive behavioural therapy although not for a number of years now. Even when I was training back in the late 80s Jung and his precedents were no longer taken seriously. For anyone who's interested the ONLY therapy with strong positive evidence of efficacy is CBT and it's derivatives - including Family Therapy.
