In the metaphysical, Honey I Shrunk The Kids-style experiment, researchers suited up 18 test subjects with virtual reality helmets, landing them in a computer-generated room with posters on the walls. (As a cheeky aside, the posters had pictures of Mickey Mouse and a computer mouse.) Another pixely human avatar was in the room with them. The subjects were told they were going to a) be working with a human to solve tasks, or b) interacting with a rat controlling the other avatar. Regardless of what researchers told them, they were working with a rat in a box, kilometers away.
