A small device, the Predictor, looks like a remote control. It consists of a button and a green display. When you press the button, the screen flashes. However, it flashes a second before you click on the button—by receiving a signal a second from the future. Millions of these devices have been sold. The Predictors create a dystopic world by providing evidence that free will is actually a myth—the future is predetermined and fixed. As a result, people become lethargic and just stop eating entirely.
