I am about to show you a simple doctored photograph of a woman’s face. But it has been so artfully rearranged that your brain will insist that your eyes are malfunctioning somehow and it will fight to resolve the image into something that it isn’t. If you’re anything like me, this process will give you a headache very quickly. It all goes to show what an active process seeing is. You think you’re just passively taking in the world, but in fact you’re busy busy busy constructing it all the time. It takes an illusion like this to drive that point home.
Here you go: Are U drunk.
