Your Brain Deletes Most of What You See (And Your Ancestors Needed It To)

Nothing you have ever seen was real. Not your phone, not your room, not your mother's face. Every image you've ever had was a guess your brain made up and showed you as fact. Your eyes send your brain far more than it can handle, so it throws most of it away and invents the rest. In this video, you'll see how your retina squeezes 126 million signals into 1 million, why you go blind several times every second without noticing, the blind spot your brain paints over in both eyes, the invisible gorilla experiment, and the door study where people didn't notice they were talking to a completely different person. Then the twist: this isn't a flaw. For your ancestors on the savanna, a brain that saw everything would have been slow, hungry and eaten. A brain that deleted most of reality and noticed only what mattered kept them alive, and it's still running in your head today. ━━━━━━━━━━━━━━━━━━━━ ⏱️ CHAPTERS ━━━━━━━━━━━━━━━━━━━━ 0:00 Nothing you have ever seen was real 0:31 126 million signals in, 1 million out 1:48 Try this: your vision is mostly blurry 2:27 Saccades and why you're blind many times a second 3:20 The stopped clock illusion 3:55 The blind spot in both your eyes 4:44 The invisible gorilla experiment 5:41 The door study and change blindness 6:29 Why evolution built a brain that deletes reality 7:45 Predictive processing: your brain guesses first 9:14 Why you stop seeing the people you love 9:47 How your phone hijacks your attention 10:15 What you can do about it ━━━━━━━━━━━━━━━━━━━━ 📚 THE RESEARCH IN THIS VIDEO ━━━━━━━━━━━━━━━━━━━━ Retina: https://en.wikipedia.org/wiki/Retina Optic nerve: https://en.wikipedia.org/wiki/Optic_n...
