I have experienced this in person with a developer who was failing to debug something. An error message was popping up on screen and he was reflexively clicking it away faster than anybody could read it. Even after being told “an error message is popping up, don’t dismiss it”, even after being told “[do the thing that triggers the bug] and then completely stop without doing anything else”, and a whole bunch of other ways of phrasing it, he was unable to understand that the error message contained useful information that we needed to see. I’m not even sure he was consciously aware it existed or that he was doing it. After many failed attempts at getting him to stop I literally had to take the mouse away from him and do it myself. I was shocked that apparently nothing anybody could say would stop him from dismissing the error message without even looking at it.
