Fair enough. "Lack of status regulation emotions" is a bit more narrow, perhaps? Either way I see them as very similar concepts, and in the context of HPMOR readers' anger especially so.
If someone who is high status lacks status regulation emotions they will be nice to a person with low status who seeks help from them and treats them as an equal.
That's the opposite behavior of what's commonly called having an ego.

I guess there'll be a fair bit of traffic coming from people looking it up?
