I have a right dominant eye.
Extend your arm completely, hold one finger up, with both eyes open align your finger with a distant object, like the corner of a wall. Now close one eye, then open that eye and close the other. Most people should see a major shift in perception from one eye, while the image from the other eye appears relatively the same.

I necessarily have the passion for writing this, and you have the passion for condemning me; both of us are equally fools, equally the toys of destiny. Your nature is to do harm, mine is to love truth, and to make it public in spite of you. - Voltaire

That is your Master Eye. That's the one you should be using to line up the sights on your rifle.
Hail, Hail!!!

Count how many times the people in the white shirts pass the basketball.
EDIT: This particular study is not included on the DVD.

See, if you can see what's wrong with this scene.
Note, the woman is unaware of the experiment.

You have co-dominant eyes then. Lucky you.
Are you a woman?
Maybe you have 4 pigments for color as well.
Yes, I'm a woman

Cool, women have a chance of having 4 pigements for colour, where as men have a chance of only have 2. So, while men can be color-blind, women can have super color vision.
I guess that's why women are more fashionable, statistically speaking.
Cool, I knew there had to be a scientific explanation as to why I have such a keen fashion sense!

they switched the papers,...
~Ron Burgundy
Actually, two of the people switched places as the two men with the board walked in-between.
The experiment was to see if the people would notice that they were talking to a completely different person, or that the guys clothes had changed.
Interestingly they don't notice.
EDIT: Although, some of the people claimed to have noticed, even though they didn't appear to at the time.
i looked at them again and holy shit, totally didn't catch it,... how many people catch on the first time? i don't want to be the solo idiot
~Ron Burgundy
I didn't catch it, and I just showed it to a coworker that didn't catch it. Clearly the subject in the video didn't notice, and to think those guys had different faces and probably different voices as well.

There are 3 frames, first frame is unedited, second frame is blank (required), 3rd frame is doctored.
So the idea is, to see what is different between the first frame and the 3rd frame.
The 2nd frame is required for the experiment, going from the original photo to the editted photo and the solution is too obvious. With the blank frame, it tricks the eyes.
So, when you see it cool, please don't post what it is, because it will spoil it, once you know the difference, you will always see it, even a year from now.

This is David Copperfield guessing your card via the internet.
It's a very simple trick, really.
lol. Yea, it's a relatively large change.
There are dozens of these change-blindness examples on the internet. They are kind of fun do to, and kind of frustrating.
BTW, It's inversely related to IQ!
No, I'm just joking.
I tried the other ones. That one is the toughest.
Yea, I like that one, there is a full explanation of it, between the Eyes, Visual Cortex and B1 B2 neural networks. The eyes are actually seeing everything in all of these experiments, it's the visual cortex and the connected neural networks that are erroneous.

I should note here too, that if you have 4 pigments for color, there is a likelihood that you could have a color-blind son. I don't if that is exactly true or why, that's just what I heard on a lecture series about visual cognition.
Is there a zebra wandering around?
