“Cognitive theorists have a term for what Eve just experienced. They call it her Hypersensitive Agency Detection Device, or HADD. This is a biological process that arose deep in our evolutionary past, all the way back in the days when hominids were still stooped and hairy. In its simplest terms, HADD leads us to detect human agency, and hence a human cause, behind any unexplained event: a distant sound in the woods, a flash of light in the sky, a tendril of fog slithering along the ground.”
