Meyers-Briggs was never meant to pigeon-hole people so that organizations could be better aligned, or for social engineering purposes. As a psychoanalytic tool, its main purpose is to help the subject understand his or her own inclinations. Any application outside of therapy or introspection is pop-science; and any application within those fields is only relevant if the subject accepts the categorizations of the test.
