Why do we see illusions? - Mark Changizi?

We see illusions because our brain is trying to guess what’s happening around us, just like when you play a game and try to figure out what your friend is thinking.

Illusions are tricky pictures or things that fool our brains, making them think something is one way when it's really another. It’s kind of like when you wear glasses that make everything look wobbly, even though the world isn’t actually shaking, your brain thinks it is!

Our brain is super fast and always trying to predict what comes next. When we see an illusion, our brain is like a detective solving a mystery with clues from our eyes.

For example, sometimes pictures look 3D even though they're flat, just like how a cardboard box can feel solid when you touch it, even though it's just paper and glue. Your brain thinks it’s real because it knows what boxes are supposed to feel like!

Illusions help us understand how our brain works, kind of like learning how to solve puzzles. It shows that what we see isn’t always what’s really there, it's more like a clever guess from our brain!
