6 vs 7: Type 7 is much more likely to be charming than type 6 and considerably more adaptable. The experience of anger, in the other hand, is more prominent in type 6. Most striking is the difference in regard to guilt as characteristic in the latter by its presence as it is in the former by its absence. Whereas type 6 has a hierarchical view of relations type 7 approaches people as equals and is little intimidated by authority. While type 7 is, in a broad sense of the word, a fear type, he is not prompt to anxiety as type 6, and fear is only a psychodynamic aspect behind compulsive gentleness.
He did not write comparisons for 5 and 7, AFAIK, and that’s related to why I’m recommending him here (though to be fair I usually do recommend him). 5 and 7 are both head/fear types but they deal with the whole thing in dissimilar if not opposite ways, so it should (keyword, should) probably be hard to confuse them or relate to both as a possible core. Enough so that Naranjo seems not to have thought comparing them very necessary.
5 vs 6: May be confused in virtue of the schizoid features of type 5 as well as the sad moods of the more avoidant subtype. Also type 5 can be, as type 6, distrustful, yet the distrust is more avoidant than even in the avoidant or phobic type 6 who is more dependent, more affectionate and generous, both in terms of availability and in the quality of being good hosts. Also type 6 is comparatively more disciplined, and takes external authority more into account, both in terms of submissiveness to conventional or actual authority, and dominance towards those lower in the authority hierarchy.
