Football fans found an unlikely oracle during the 2008 European championship: an octopus named Paul. Before each match his keepers at the Sea Life Centre in Oberhausen, Germany, would lower two boxes of food into his tank, each bearing the flag of an upcoming competitor. Surprisingly, Paul correctly chose the winner in four of Germany’s six games.
When some observers expressed skepticism, Paul went on to pick the winners of all seven of Germany’s World Cup games in 2010, as well as the final between Spain and the Netherlands, giving him an overall success rate of 85 percent.
Competitors sprang up around the world, including a Singaporean parakeet, a German parrot, and a saltwater crocodile named Dirty Harry, who predicted the result of Australia’s general election by snatching a chicken carcass dangling beneath a caricature of Prime Minister Julia Gillard. Maybe we should quit while we’re ahead.
