Your Fear of Dark Hallways Isn't Irrational | It's Ancestral

Why do we have a primal fear of the dark? Is it monsters, or something deeper? Discover the evolutionary psychology behind why humans are hardwired to fear the night and how ancient survival instincts shape your modern behavior. Tonight, when you flip a light switch, you're doing something your ancestors couldn't. For most of human history, darkness meant vulnerability. In this video, we explore the science of nyctophobia and why your brain treats a dark hallway like a critical threat to survival. We break down why fire was the ultimate tool for human evolution, why the fear of the dark is actually a fear of "uncertainty," and why that nervous flinch you feel at night is an ancestral message from the survivors who kept our species alive.
