“As objects go, it doesn’t look like much. It’s, you know, a yellow card. But when theatrically brandished by an official, almost literally in the face of a player who has done something uncool, it has wild power. It sets off a stadium-full of whistling, and cartoonish arm-flailing from the carded player and his colleagues. A yellow card has real consequences: Possession, a free kick, and the possibility that if the carded competitor blunders again he’ll leave his team understaffed for this match, and will sit out the next.”
And what if we could introduce this system into everyday life?
