Beta: too rigid, too narrow minded, too insecure. Ugly - they have no sense of beauty or peace. Their thought process are limited by Se>Ne, and are aristocratic, creating a false sense of dichotomy. Many of them live their whole life like they are in high school, no progress, no change
Gamma: More concerned with "getting there" then where we are going, progress without direction, or in the wrong direction. Ugly - they have no sense of beauty or peace, and above in regard to disregarding Ne for Se. The attitude of "as long as my direct relationships are fine, everything else in the world is fine" (Se + Fi), which is of course a way to convince yourself that avoiding Fe and Si is acceptable.
Delta: Hedonistic to a fault - about certain things. And on other matters, they are very sound at compromising their values. It seems to be a matter of ethical perception -- what is the loophole in their principles that allows them to gratify their desires? May have an unrealistically high moral image of themselves (more for ratoinals). For the irrationals, they may have an unrealistically non-existant take on principles, focusing on whatever gratifies them. Like old people, with their grand ideals and what they consider wisdom, but little means of accomplishing it themselves. (Whereas betas are better at doing things, but may have a poor sense of direction and working with people outside of their cliques)
