On August 10, 1948, a pioneering television producer named Allen Funt debuted a hidden-camera reality TV show called Candid Camera. The genius of the show is that it caught people in the act of being themselves. It produced lots of laughs, but it also offered a fascinating look into the human psyche.

In one episode titled "Face the Rear," an unsuspecting person boarded an elevator and naturally turned around to face the front of the elevator. That's when three actors entered the elevator and faced the rear. A hidden camera in the elevator captured the angst of the prankee. To turn or not to turn? Finally, a fourth actor entered the elevator and faced the rear. Without exception, the person facing the front would turn around and face the rear. The social influence exerted by those facing the rear was too overwhelming for that person to remain the only one facing the front.
