Analytics savant Nate Silver and his team at the FiveThirtyEight blog have hit a wall with the upcoming papal election.
They will not be sticking their necks outwith a prediction for the conclave vote, citing a dearth of conventional polling data to plug into their models.
Sitting out the most-watched election on the planet speaks to the difficulties of building a statistical model to short-list the papabili, or men most likely to be appointed pope.
The outcome of the papal conclave vote is far more difficult to forecast than, say, a political election.
For starters, you have to account for a two-thirds clinching vote rather than a simple majority.
Secondly, historical voting data from the College of Cardinals will get you only so far. For example, 67 of the 115 cardinal electors voting in this conclave (or, 58 percent) are first-timers.
Still, these obstacles aren’t stopping Vatican watchers and oddsmakers from predicting the next pontiff. They contend there is enough available data to crunch from previous conclaves to handicap the 2013 field. After running the numbers, here is what the papal forecasters have to say about the upcoming vote:
The frontrunner factor
As conclave veteran John L. Allen Jr. wrote in National Catholic Reporter last week, you can throw out the old bromide, “He who enters as pope exits as a cardinal.”
Allen crunched the data on the past six conclaves dating back to 1939, concluding that there has only been one complete stunner—Cardinal Karol Wojtyla, elected Pope John Paul II in 1978.
All other future popes entered the conclave riding a wave of positive buzz.
This time round, many oddsmakers, including Oddschecker.com andPaddy Power, are tipping Italian cardinals Angelo Scola and Tarcisio Bertone and Ghana’s Cardinal Peter Turkson as the ones to watch, with Cardinal Sean O’Malley of Boston emerging as a dark-horse candidate.
The fab five
There may be 115 candidates for this conclave, but history shows that after the initial voting rounds, the serious contenders will be winnowed down to “a subset of five or fewer,” according to a 2004 study by J.T. Toman, an econometrics and business statistics professor at the University of Sydney. Continue reading
