You are thinking of the alarm fatigue[1], but it doesn't apply here -- there are no constant alerts warning that you are doing something dangerous to the point you get desensitized and start to ignore them. The correct analogy here are checklists -- things that you need to check if you are to do this "dangerous" activity (AUR usage), akin to pre-flight checklist.

Oh yeah, that's the name of it. But I guess something similar happens with checklists, you do it so many times without anything bad ever appearing that you start to subconsciously assume nothing will ever happen. Why check the rotor of my helicopter when nothing ever happened to it for 5 years? This checklist is a waste of time!
