Seeing Isn’t Always Believing

Cognitive scientists say that we can predict the future up to one-tenth of a second before something actually happens. Our brain is constantly slower than the things that happen around us, this means it takes a little while for our brain to convert what we see into what is actually happening right now.

The lag in what we see and what our brain processes are compensated by our brain’s motor system, it offsets the delay by predicting the events that are most likely to occur. It’s a useful evolutionary trait which has allowed us to close the one-tenth second gap between our sight and our mind.

Optical Illusions work by making our brain predict what should be happening in front of our eyes. The trick is that our mind’s perception does not match that of reality.
