Pretty self-explanatory, are certain types more likely to have similar scores on the Big Five categories (Openness, Conscientiousness, Extroversion, Agreeableness, Neuroticism)? It seems that, since the Big Five is one of the more accepted personality descriptors, if we can associate type and the five dimensions, it may be beneficial for precision or... something else, no doubt.

And apologies if there is already a thread related to this.
