I don't think that the thing Eliezer called "lack of status regulation emotions" that makes some people angry when they read how Harry in HPMOR interacts with teachers is what commonly called ego or lack of ego.
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.

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