Visual Illusions And Your Brain's Construction Of Reality. What This Means And Why It Matters

So many illusions work like this: Even when you’re told about the trick, you can’t unsee the illusion. Take the classic checker-shadow illusion by Edward Adelson. Squares A and B are the exact same shade of gray when seen side by side. But when B is cast in an apparent shadow and surrounded by apparently darker tiles, it just looks lighter. There’s nothing about the physical construction of our eyes that would cause this effect, I’m told.The apparent lightening of tile B is a story told by our brains.
