As I understand the Myers-Briggs Type Indicator, your "type" is a
composite of four trait scores: Introversion vs. Extroversion;
Intuitiveness (N) vs. Sensing (S); Thinking vs. Feeling, and
Judging vs. Perceiving. Apart from Introversion vs. Extroversion,
the three other traits are so poorly defined as to be all but
worthless from a psychometric point of view (cf. Dr. Grant's
reference to the poor test-retest reliability of the MBTI).

As for the marketing problems associated with the Big Five:
I notice that some authorities use SLOAN (Social, Limbic,
Orderliness, Accommodation, and Non-curiosity) while others use
OCEAN or CANOE (Openness, the opposite of SLOAN Non-curiosity;
Conscientiousness, corresponding to SLOAN Orderliness;
Extroversion, corresponding to SLOAN Social; Agreeableness,
corresponding to SLOAN Accommodation; and Neuroticism,
corresponding to SLOAN Limbic) as the acronym describing the Big
Five traits. Superficially, those different terminologies suggest
to the public that the Big Five is less reliable than MBTI; this
contributes to public reluctance to use it. After all, Intuitive
is Intuitive is Intuitive, right? (Not necessarily.)

For what it's worth; my MBTI trait scores usually correspond to the INTJ personality type.
