In a Sev2 that might become a Sev1, people argue about preferences when the real issue is structure. You see it in a shortcut that becomes the new operating mode, where the system teaches everyone the wrong behavior. If you introduce a measure, name the distortion it creates, because the distortion is part of the cost you are choosing.
