From the Ted Talk "Al Seckel: Visual illusions that show how we (mis)think"

Unscramble the Blue Letters

So I'm going to show you some ways that we can violate your expectations. First of all, I want to show you the particular illusion here. I want you first of all when it pops up on the screen to notice that the two slheo are perpendicular to each other. These are all perceptual ctrisk. These are real objects that I'm going to show you. Now I'm going to show you how it is done. I've looped the film here so you can get a very interesting experience. I want you to see how this illusion is constructed, and it's going to rotate so you see that it's inside out. Now hactw, as it rotates back, how quickly your perception snaps. OK now. Watch it as it oretast back again. And this is a very bright audience, all right? See if you can stop it from happening, even though you know 100 percent it's true that — bam! You can't undo it. What does that tell you about yourselves? We're going to do it again. No dubot about it. See if you can stop it from happening. No. It's ftdifcuil.

Original Text

So I'm going to show you some ways that we can violate your expectations. First of all, I want to show you the particular illusion here. I want you first of all when it pops up on the screen to notice that the two holes are perpendicular to each other. These are all perceptual tricks. These are real objects that I'm going to show you. Now I'm going to show you how it is done. I've looped the film here so you can get a very interesting experience. I want you to see how this illusion is constructed, and it's going to rotate so you see that it's inside out. Now watch, as it rotates back, how quickly your perception snaps. OK now. Watch it as it rotates back again. And this is a very bright audience, all right? See if you can stop it from happening, even though you know 100 percent it's true that — bam! You can't undo it. What does that tell you about yourselves? We're going to do it again. No doubt about it. See if you can stop it from happening. No. It's difficult.
