It is surprising how easy it is to misperceive what is right in front of you. Sometimes, even the obvious is not obvious. When under a high workload, or under stress, you perceive what you want to see regardless of the visual evidence.
I think that many aviators have experienced this, usually without a bad result. There are many tricks that can be used to help you but, in the hurly-burly of the real world it is not always easy to apply them.
I think we should wait until the aviation psychologists have had something to say about this one.
