At least on the types, INTP probably refers to a real phenotype (which is common on LW)
Myers-Briggs ultimately derives from the psychodynamic theories of Carl Jung, who was himself an INTP. Thus, it makes sense that INTP roughly corresponds to an actual personality type; Jung simply described himself, and then turned to his existing theories to explain away why he was the way he was.
