Disagree: the DiSC personality assessment codifies dominance as a key motivator of behavior. As much as I think the DiSC assessment is just business horoscopes, I still see canonizing dominance as a response to a real impulse, along with a way to easily sell decision makers on the fact that they are, in fact, just wired differently from all those other people below them.
Yup. There's probably an infinite appetite for business horoscopes that tell people what they want to hear. Just have to dress it up with a veneer of authority.
