I pulled this from a spam thread about God.
People sometimes say: I believe what I see. This goes to show you that so much more goes around you than what you can perceive, even if it right in front of you.
The Discovery Channel aired a BBC production today that showed that we don't even "see" what we see.
They took a group of 20 adults and asked them to watch a video of 6 basketball players doing a passing drill. 3 were wearing black uniforms, 3 were wearing yellow uniforms. They were told to count the number of passes made by the players in yellow and ignore the passes by the players in black.
Midway through the video and man in an ape suit walked between the players, beat his chest then walked of screen, the video then stopped.
When asked if anyone saw anything unusual only 4 of 20 raised their hands.
The video was played again with no instructions and everyone starting gasping at missing the ape the first time.
The point was that the mind can only process so much information at once, and for those things we are not actively working on, we make assumptions of what we are seeing based on experience, and are not actually "seeing " what is there.
As the viewer you laugh, knowing for sure you would have seen the ape. The announcer then gets the apeman and says to the TV, "Does he look familiar to you?"
They then rewind the show pausing at all the times they had placed the ape in the backround, but in plain sight. I imagine most people were a little shocked.
