Why You Flinch Before You Even See What Scared You

A balloon pops behind you and your body reacts before your mind even knows why. You like to think you're in control of every move you make. The real answer is far stranger than instinct, and far older than you. In this video, you'll discover the hidden neural shortcut that lets your brain react to danger a full quarter-second before you're consciously aware anything happened. You'll learn why your visual system is secretly biased toward spotting threats, how scientists proved your brain can fear something you never even saw, and why this 200,000-year-old alarm system still runs the show today. By the end, you'll understand exactly why you are not broken, not overreacting, just running ancient software.
