Sometimes in education this happens as well and of course, this affects children's lives very seriously. If students aren't learning we need to have the right tools to diagnose why and know what we need to examine. We need to listen and observe and experiment carefully to see what can "fix" the "problem" or what the problem actually is. Spending time and money, for instance, administering and scoring standardized tests is a very ineffective use of resources. This isn't opening the "control panel". Careful observation by a skilled practitioner of how a student learns does open the control panel.
P.S. I just found this website (not that this was exactly what the third electrian did) -maybe the first two electricians should have watched this video.
