Paul (hatched January 2008) is a common octopus living in a tank at a Sea Life Centre in Oberhausen, Germany, who is used as an animal oracle to predict the results of football matches, usually international matches in which Germany is playing. He came to worldwide attention with his accurate predictions in the 2010 World Cup.

During a divination, Paul is presented with two boxes containing food in the form of a mussel, each marked with the flag of a national football team in an upcoming match. He chose the box with the flag of the winning team in four of Germany's six Euro 2008 matches, and in all seven of their matches in the 2010 World Cup. He correctly predicted a win for Spain against the Netherlands in the World Cup final on 11 July by eating the mussel in the box with the Spanish flag on it.[1] His predictions have thus been 100% (8/8) correct for the 2010 World Cup and 86% (12/14) correct overall.

Life

Paul was hatched from an egg at the Sea Life Centre in Weymouth, England, then moved to a tank at one of the chain's centres in Oberhausen, Germany.[2] His name derives from the title of a poem by the German children's writer Boy Lornsen: Der Tintenfisch Paul Oktopus.[3][4]

The animal rights organization PETA have argued that it would be cruel to keep Paul in permanent confinement. Sea Life Centres have responded that it would be dangerous to release him, because he was born in captivity, and is not accustomed to finding food for himself.[5]

According to DPA, local businessmen in Carballiño, a community in Galicia (Spain) collected about 30,000 Euro "Transfer fee" to get Paul as main attraction of the local Fiesta del Pulpo festival.[6] Manuel Pazo, a fisherman and head of the local business club made assurances that Paul would be presented alive in a tank and not on the menu. Sea Life Centres rejected the offer nevertheless.[7]

Divination

Paul's career as an oracle began during the UEFA Euro 2008 tournament.[2][4][8] In the lead-up to Germany's international football matches, Paul is presented with two clear plastic boxes, each containing food: a mussel or an oyster. Each container is marked with the flag of a team, one the flag of Germany, and the other the flag of Germany's opponent. The box which Paul opens first (and eats the contents of) is judged to be the predicted winner of the game.[9]

Paul's apparent success is comparable to a run of luck when tossing a coin. This connection has been made by Professor Chris Budd of the University of Bath, Professor David Spiegelharter of Cambridge University, and Etienne Roquain of Pierre and Marie Curie University.[10][11]

Under the hypothesis that Paul is equally likely to choose the winner or the loser of a match, and neglecting the possibility of a draw, he has a 1/2 chance of predicting a single result and a 1/64 chance of predicting six in a row. This feat would be unlikely, but not nearly as unlikely as winning the UK lottery, a chance of 1/14 million. Spiegelharter and Roquain point out that there are "other animals that have attempted but failed to predict the outcome of football matches"; it is not remarkable that one animal is more successful than the others, and only the successful animals will gain public attention after the fact.[10][11] However, if Paul or other octopuses[12] felt attracted for whatever reasons to the flagged boxes of Germany or Spain, their predections would be much more exact than tossing a coin. This applies only for ongoing international football tournaments but would fail for any other question.

Potential biases

Flag of Germany: A horizontal tricolor of black, red and gold
Germany (11)
Flag of Spain: A horizontal tricolor of red, yellow and red, the yellow stripe being twice the size of each red stripe and containing the coat of arms
Spain (2)
Flag of Serbia: A horizontal tricolor of red, blue. and white, with the lesser coat of arms
Serbia (1)
Flags picked by Paul

Roquain goes on to admit that chance is not necessarily the only explanation for Paul's choices. He could be choosing boxes systematically—if not on the basis of football expertise, then perhaps on his evaluation of the countries' flags or the food offered.[11]

The species Octopus vulgaris is almost certainly color blind; neither behavioral studies nor electroretinogram experiments show any discrimination of a color's hue.[13][14] Nonetheless, individuals can distinguish brightness as well as an object's size, shape, and orientation. Shelagh Malham of Bangor University states that they are drawn to horizontal shapes, and indeed, there are horizontal stripes on the flags he has chosen. The flag of Germany, a bold tricolor consisting of three equal horizontal bands of black, red and gold, is Paul's usual favorite. But the flag of Spain, with its broad yellow stripe, and the flag of Serbia, with its contrast of blue and white, are more vivid still, possibly explaining why Paul picked those countries over Germany.[13] Fey suggested that Paul was confused by the similarities between the German and Spanish flags; this was on July 6, when Fey expressed hope that Paul's latest pick would be wrong.[15]

Matthew Fuller, the senior aquarist at the Weymouth park, judged the flag-shape theory to be plausible: "[Octopuses] are the most intelligent of all the invertebrates and studies have shown they are able to distinguish shapes and patterns so maybe he’s able to recognise flags."[16] Vyacheslav Bisikov, a Russian biologist, agrees that it is possible for an octopus to become attracted to a striped flag.[17] However, Pascal Coutant, director of the La Rochelle Aquarium states: "It's complete chance that guides his choices."[18]

Octopus vulgaris is also equipped with sensitive chemoreceptors on its tentacles, which are used to taste food and "smell" the water. Biologist Volker Miske, of the University of Greifswald, suggests that minor chemical differences on the surface of each box might account for Paul's decisions.[19] Bisikov states that Paul could be "easily trained" to choose the right box by smell.[17] According to Paul's keepers, there are holes in the jars to help him choose.[20]

Theories of his behavior could be systematically tested if Paul were to repeat his selection many times, but he only selects one box per game.[19] A scientific experiment would be more vigilant towards sources of bias, including the flag visuals and potential differences in the preparation of the food.[11]

Results

Paul holds a press conference, 6 July 2010.

In UEFA Euro 2008, Paul correctly predicted the outcome of 4 out of 6 of Germany's matches. He failed to predict their defeats by Croatia in the group stage,[21] and by Spain in the championship's final.[2][nb 1]

2010 FIFA World Cup

Paul's accurate choices for the 2010 World Cup, broadcast live by German news channel NTV, have endowed him with celebrity status.[2] Paul predicted the winners of each of the seven 2010 FIFA World Cup matches that the German team played, against Australia, Serbia, Ghana, England, Argentina, Spain,[23] and Uruguay. His prediction that Argentina would lose prompted Argentine chef Nicolas Bedorrou to post an octopus recipe on Facebook.[2]

There are always people who want to eat our octopus but he is not shy and we are here to protect him as well. He will survive.

— Oliver Walenciak (Paul's keeper)[24]

Paul correctly predicted the outcome of the semi-final, by choosing the food in the box marked with the Spanish flag. German supporters drew hope from his incorrect choice for the Germany versus Spain match in the UEFA Euro 2008 but were disappointed.[25] The prediction led to death threats as German fans called for Paul to be cooked and eaten.[26][27] In response, Spanish prime minister Jose Zapatero jokingly offered to send Paul official state protection, and the Industry Minister Miguel Sebastian called for Paul to be given safe haven in Spain.[28][29] Paul maintained a 100% accurate record during the tournament by correctly predicting Spain's victory over the Netherlands in the final.

Statistics

Assuming Paul's predictions were no better than fair independent coin flips, the probability of 12 successful predictions in 14 attempts is 91/1684 ≈ 0.56%, as given by the binomial distribution[35], and the probability of 8 successful predictions out of 8 attempts is 1/256 ≈ 0.39%.[36]. Of course there were many public predictions about World Cup results using quirky methods that were wrong and hence did not get international attention. It is an example of the Prosecutor's fallacy to use the same data that brought Paul to fame to suggest that he has precognition. Paul started to receive international recognition after he correctly predicted Germany's win over England, and after that he only made four more predictions. The chance of all of those being correct was 6.25%.

Similar oracles

Some other oracles did not fare so well in the World Cup. The animals at the Chemnitz Zoo in Germany were wrong on all of Germany's group-stage games, with Leon the porcupine picking Australia, Petty the pygmy hippopotamus spurning Serbia's apple-topped pile of hay, and Anton the tamarin eating a raisin representing Ghana. Mani the Parakeet of Singapore picked the Netherlands to win the final.[37][38][39]
