Humans are fantastic at ignoring noise and concentrating on whatever we want to focus on. While you're reading this very comment do you have any idea how much noise is in your field of vision that you're ignoring? Not just on this screen at the same time (literally megabytes of other bitmaps besides my words) but the rest of your field of vision. Really look around. This message contains 575 bytes of text embedded in gigabytes of moving video you're ignoring. (Just one example.)

But if the information isn't there, no amount being human can bring it out. You're stuck.
