The Myers-Briggs categories are more neutrally named than those of the "Big Five".
SENSING VS INTUITION is called OPENNESS in the Big Five.
THINKING VS. FEELING is called AGREEABLENESS
JUDGING VS. PERCEIVING is called CONSCIENTIOUSNESS
So people who rate as SENSING, THINKING, and PERCEIVING in the Myers Briggs scale would be rated as "low" in openness, agreeableness, and conscientiousness in the Big Five.
Seems pretty clear why the Big Five would never catch on in popular culture. Oh, and the fifth category is "Neuroticism". Not exactly a neutral label either.
I think even if it were more neutrally named it would still be less popular than Myers-Brigs because MB gives you an either or which gives you the simple [E/I][S/N][T/F][J/P] categories which maps to just 16 convenient categories where the Big Five tests spit out numerical scores ranking you relative to the population. The former lends itself to the kind of short in grouping and desire for fast categorization that keeps horoscopes popular, Myer-Brigs giving you ENSP is a clear group to belong to with all sorts of "what does it mean to be ENSP" articles to write, where the former doesn't really give you a clear concise slot to use it in. The closest would just be ranking high or low in each category but that's 32 groups and long to type compared to the 4 letter MB personality groups.
