This follows a pretty simple pattern for me: "people don't want to be wrong" They have a certain vision for themselves, they know what's important, they spent time to do it the right way. If something is wrong, its clearly because something else failed, in this case, you. It breaks their idea for themselves. I think it is less about rationality as I've seen just about everyone do this at various points, and more being humble and willing to own up to when was had an oversight, letting go of the ego to be able to say, "huh, I completely missed that you wrote this. I understand that you said you have brought this up before, even if I don't remember it, I believe you. I will dig into this and listen better here on out." How rare is that behavior?
