This is a good point. I agree with your larger point about the glass ceiling being related to traits, but it also seems to me that even if a female employee is a wolf, there's a lot of disadvantage that comes with all of the male executives in the C-suite deciding that she looks like a bunny the moment she arrives.

Maybe that's the source of a lot of the classic "glass ceiling" effect -- groups of male executives deciding en masse that a female executive is easy game, based on nothing but her appearance alone. At that point, she'd have to fight against 10x as much opposition as any of her male colleagues in the same position. Even a wolf has limits when everyone else is against them.
