Are some Enneagram types incompatible/not possible in certain MBTI types? (e.g. INTJ 4, ESTJ 2, INFP 3, ISFJ 8, ESTP 5) I've seen some talk of such, like how it goes against "natural" tendencies of type and cognitive functions.
There are correlations/tendencies -- that's undeniable, but are some combinations simply nonexistent?
If not, how would these seemingly contradictory types manifest itself in people?
