One consequence of the popularity of the MBTI is that it has become increasingly detached from psychological type theory - often to the detriment of the individuals whom it is intended to benefit. Reconnecting the MBTI to type theory has critical practical implications and applications. In this regard, the overall goal of this edition is identical to that of the two editons that preceded it, and indeed to that of the Indicator itself: to make the theory of psychological types described by Jung understandable and useful in people's lives.
