How much do we really see?

I came across an interesting video that asks us, how much do we really see? We all think we're good observers and can watch closely and carefully but how often do our eyes really deceive us?

For example, how many times do the people in the white shirts bounce the ball on the ground? You can take a look at this video here. Watch it only once and no-pausing, the ball sometimes moves fast so pay attention. I'll wait for you to come back.


No cheating, go watch the video if you haven't already.

How many people counted 10 bounces? Perhaps 9, or 11? Ok then. How many of you noticed the gorilla? You didn't see the gorilla? It was right there in the middle of the screen! Go watch it again.

For me this was a stunning example of how we sometimes can't see what's right in front of our eyes. It also makes me wonder how many other things happen every day all around us that we simply didn't notice.
