Alpha: Betas tend to regard Alpha types as pleasant company, fun, creative, and generators of ideas, but too goofy and present-oriented, lacking focus and ambition, needing to be led.
Gamma: Betas tend to regard Gamma types as stand-offish and occasionally emotionally hostile, judgemental, and inclined to not seeing the "big picture" in political or work situations, a combination of political naivity and moral stiffness which may end up jeopardizing the Betas' goals. Socially boring, "can't take a joke", vindictive.
Delta: Betas tend to regard Delta types as noncommittal in their unwillingness to support goals decided in a group, lack of drive, and ethical self-righteousness. Rather than back group efforts that require vision and concentration of effort, Delta types prefer to just work on personal projects.
