Fortunately, there’s an interesting thing that happens when you watch TV—your eyes focus on the person who’s talking. This is a form of something called “inattentional blindness.” Daniel Simons, in Smithsonian magazine, describes it like this: “This form of invisibility depends not on the limits of the eye, but on the limits of the mind. We consciously see only a small subset of our visual world, and when our attention is focused on one thing, we fail to notice other, unexpected things around us—including those we might want to see.”
