Unfortunately, the existence of such emotional tags, while making memory retrieval quicker and easier, does not guarantee that the memory retrieval will be more accurate. Here is an example. If you are like most Americans, you remember right where you were when you first learned that the World Trade Center Twin Towers in New York City had been attacked on September 11, 2001. You probably remember the room you were in, roughly the time of day (morning, afternoon, evening), and perhaps even who you were with or who you spoke to that day. You probably also remember watching the horrifying television images of an airplane crashing into the first tower (the North Tower), and then, about twenty minutes later, the image of a second plane crashing into the second tower (the South Tower). Indeed, according to a recent survey, 80% of Americans share this memory. But it turns out this memory is completely false. The television networks broadcasted real-time video of the South Tower collision on September 11, but video of the North Tower collision wasn't available and didn't appear on broadcast television until the following day, on September 12.
