In perhaps the most elaborate example of Nobel guesswork, the scientific division of news and financial information provider Thomson Reuters analyzes thousands of citations and papers in high-impact academic journals to identify possible winners of the science and economics awards.
Even though they allow themselves three guesses for each of those four prizes, the Thomson Reuters analysts led by David Pendlebury haven't predicted a winner since the 2009 medicine award. Of the 158 scientists they have identified as potential Nobel laureates since 2002, 26 have won, but only nine in the year they had predicted.
"If we do get any of these right it's all the more remarkable, because we have no field expertise," said Pendlebury, whose academic background is in ancient history. The main difficulty in making forecasts, he said, is that "there are more people of Nobel class than there are Nobel Prizes to go around."
The scholars and literature buffs speculating on Nobel Prizes may be different from the crowd predicting scores in sports bars, but the psychology is similar.
When accurate guesses are rare, a person making an inaccurate guess can easily dismiss it by saying that most other people got it wrong too, said Jiao Zhang, a professor at the University of Miami who has studied the dynamics of guess-making.
"Whereas in the rare case when his guess is accurate, he can say to himself, 'I'm among the few who got it right,'" Zhang said in an email. "Vindication and validation are sweet."
Economics — which wasn't in Nobel's will but was tacked on to the other prizes by Sweden's central bank in 1968 — is arguably the most difficult discipline to predict. Unlike Nobel-winning scientists who discovered things like X-rays or the AIDS virus, economics laureates are typically rewarded for abstract theories about market behavior.
Hubert Fromlet, a professor of international economics at Sweden's Linnaeus University, each year offers a "narrow" list with the 10 economists he believes are most likely to win. He also provides a "relatively narrow" list with 20 names and a "broader" one with 40.
But with 40 names, does it really count as I-told-you-so if one of them wins?
"Of course I feel happy when I have someone in the Top 40," Fromlet said. "But if you have someone in the top 10, it's a little bit more fun. It's not a competition. It's just something I like to do."
