I was wondering, why does the sound of chalk across a blackboard give us the chills?
Good question! Studies suggest that the sound of nails on a chalkboard may activate a primal instinct in our brains that alerts us to danger. The high-pitched screech is similar to the distress call of some primates, which could trigger a fight or flight response.
