Healthy persons of this subtype are noticeably more at ease with themselves and with other people, not feeling that they must assert themselves at every moment or in every situation. They are, at times, more open to concerns beyond their immediate self-interest, particularly those involving members of their own family. They are the kinder, more benign patresfamilias, strong willed but mild mannered, who have deeper feelings and more subtle appreciations than Eights with a Seven-wing. Eights with a Nine-wing are able to forge a personal, almost mystical, bond between themselves and others. They may be involved with the arts, nature, and children.

Average people of this subtype begin to show a definate split between the two sides of themselves - the aggressive side (which they show in public and in competitive situations) and the passive, more accommodating side (which they reveal to very few, principally their spouses). Their expansive forcefulness is grounded on some inner fortress of imperturbable strength which others are not allowed to breach. This inner sanctum is undisturbed and at peace, although it is doubtful that people of this subtype viit that inner part of themselves as much as they should. It remains an ideal. Since Eight is the basic personality type, people of this subtype dominate others, although with a velvet glove over an iron fist. They can be intimidating and belligerent, then accommodating and kind-hearted, especially to those who are close to them.

Since this subtype is almost immune from anxiety, unhealthy Eights with a Nine-wing can be destructive without remorse, combining ruthlessness with indeifference. They can get into a strangely dissociated frame of mind, acting in a depersonalized way, as if they were some sort of cosmic force which swatted people aside, crushing them without personal feelings entering the picture. People in this subtype tend, in general, to be less violent and destructive than those in the other subtype. However, if necessary, they may be violent toward others, personally regretting the suffering they cause, but not feeling any empathy or having any real understanding of what they do. They may make up for the lesser degree of violence they wreak on the environment by generally living longer, thus possibly doing more damage in the long run to those who have the misfortune to live with them.
