Has anyone looked into research regarding this "6-th factor"?
Is the book worth getting?
There is a Wikipedia Article on the HEXACO model: http://en.wikipedia.org/wiki/HEXACO_...lity_structure
One thing I believe is quite good about the HEXACO model as compared to the Big Five is that it seems more descriptive than normative. Even though, it seems like the H-factor has normative components, it doesn't seem as black-white and the Neuroticism factor in the Big Five.
