I found this personality matrice by accident, its probably less scientific than MBTI or its rivals so is it any use? I like some of the descriptions of archetypes in it, such as the priest, warrior and scholar and in her book she talks about combinations, much like how MBTI combines cognitive traits with dominance effecting the overall personality, so you could have a warrior-scholar but it will be either predominantly warrior or scholar.
Anyway, I find it interesting but mainly because the archetypes appeal to interests of my own, for instance the warrior-scholar archetype is one I've deliberately tried to integrate in my own personality and the descriptions resonate with me. Although that said you could say the same about world or warcraft. So what do you think?
