So, as I was telling my sister the other day, I'm kind of on a philosophical "Is what you see really what you get?" kick right now. Media control, appearence vs. reality, that sort of thing. So let's do an experiment. (BTW - This will not work if you've been exposed to it before.)
There is a video you need to watch, but first some directions. The video shows a group of people passing two basketballs back and forth. The people are moving around and sometimes block your view of the balls. Your mission is to count the number of passes that are made between the people. It's not easy, so you'll have to concentrate.
Ok, here's the video. It's a 7MB java applet, so you may have to be patient. Watch it, I'll wait.
I counted 29 passes. So what, you say? Well, for "The Rest of the Story", highlight the text that's hidden below. (But not until you've watched the video!)
Did you notice anything unusual occur during the video?
I sure didn't... But now, go back and watch the video again. Don't count the balls -- in fact, ignore them completely. Look at the people.
You'll see someone in a gorilla suit walk into the group of people, thump his chest, and walk out. I'm not joking. I saw this bit on a tv program once, and I was flabbergasted. I couldn't believe that I'd missed something so obvious.
This is the same principle of distraction that makes magic work. Human focus can be dogged but can also make you blind to anything else that's happening (even things, literally, in front of your face). What kinds of questions does this raise about our perceptions of reality in more general terms? What sort of obvious stuff have I missed? What have you missed?
I suppose I should get back to work.
