Why You Can't Stop Checking Your Phone (Your Brain Is Ancient)

Four minutes ago, you picked up your phone. You checked it, put it down — and your hand is already moving again. You don't know why. But the real answer is far stranger than you think, and it reaches back hundreds of thousands of years before smartphones ever existed. In this video, you'll discover why your brain was literally built to keep checking — how an ancient survival system called the wanting loop hijacks your attention, why dopamine has nothing to do with pleasure, what neuroscientist Kent Berridge found when he separated wanting from liking, and why willpower will never be enough to stop the cycle. The engineers who built your phone already knew all of this. Now you will too.
