The Brain That Invented Ghosts — Why We Can't Bear Misfortune Without a Reason

Tens of thousands of years ago, everything outside the door belonged to the unknown.

Lightning with no warning. A drought that ran for months. A sickness nobody could see, killing a hunting partner who had been fine the day before.

There was no science and no medicine. People had nothing to set against this chaos.

So the brain found a way to handle the fear. The psychologist Arie Kruglanski called it the "need for cognitive closure": a mind that cannot stand not knowing the cause.

What the brain finds hardest to bear is a gap between cause and effect. Misfortune that arrives for no reason.

When "why me?" has no answer, the helplessness wears the mind down from the inside. So the brain makes up a cause.

This is when people began to believe that trees, rocks, and wind had souls and intentions like ours. That is what animism and shamanism are at bottom.

1. No reason: "Why does the child suddenly burn with fever and lie dying?" → Nothing to do, nothing to predict. The whole group freezes.
2. A reason made up: "An evil spirit is eating the child's soul." → Once there's a cause, the fear becomes something you can act on.

Once misfortune is labeled "ghost," the helplessness lifts. If an evil spirit is the cause, there is something to do.

Call a shaman for a gut. Scatter red beans at the door. Smear it with an animal's blood.

People invented ghosts that didn't exist so that the world would have a reason in it, and so they could feel some control.

Giving an invisible fear a physical cause, then blocking it to protect your life: this old response is called byeoksa (辟邪, "warding off evil").

Byeoksa was not superstition. It was a way of thinking. The first shield a mind raised against a chaos it couldn't understand.

To fix that defense in place, people set a wooden board across the mouth of the cave and drew a line between inside and outside. That was the start of the door.
