Seems to be an ambitious rethinking of depression. As someone diagnosed bi-polar, I'll watch the development of this idea with interest.

Immobilization has an important role. It dulls pain and makes us feel disconnected. Think of a rabbit hanging limply in the fox’s mouth: that rabbit is shutting down so it won’t suffer too badly when the fox eats it. And the immobilization response also has a metabolic effect, slowing the metabolism and switching the body to ketosis. Some doctors speculate that this metabolic state could help to heal severe illness.

I could see this being the case. If I hate my job and have no other prospects on the horizon, my getting angry at stupid decisions by mgmt threaten my ability to preserve my position. But sarcastically resenting them keep me in stasis. I don't think that's a great analogy for what is being described here, but that's what I've got off the cuff.
