When a character fails to notice something important or obvious, something they would want to know, even when looking. Differs from Weirdness Censor (where they don't see it because it's so bizarre), Selective Obliviousness (where they don't want to see it), and Somebody Else's Problem (where they ignore it because they don't care). Also differs from Attention Deficit Ooh Shiny, as there usually isn't that excuse. Opposite of Hyper Awareness. Can often result in Right Behind Me (although that might be closer to failing a Listen check) or I'm Standing Right Here.
