There must be a trope for this. You watch a tv show and X is true. However, all of the characters are totally missing the obvious clues and for some reason believe that Y or Z is true. Then, you want to scream at the tv screen, and your blood pressure is rising because it's so damned obvious that X is true.
For example, the character Michael Scott gets things so wrong so extremely often, it's actually mildly stressful for me to watch The Office because of the mistakes he makes about the staggeringly obvious.
So what trope would that be?
