" Negative feedback always says in effect, “Stop what you’re doing, or the way you’re doing it—and do something else.” Its purpose is to modify response, or change the degree of forward action—not to stop all action. Negative feedback does not say, “Stop—period!” It says, “What you are doing is wrong,” but it does not say, “It is wrong to do anything. "
