In 1906 a British statistician named Francis Galton went to
a country fair in Plymouth. While there he witnessed a contest where people
wrote down their estimates of the weight of a slaughtered and dressed ox on
display. 800 people wrote their guesses on slips of paper. Most of the people
who guessed were not butchers, and so had very little first-hand knowledge to
guide them. Some of the guesses were wildly high and others were wildly low.
Yet, when Galton totaled the guesses and divided by 800, he
found that the statistical mean of the guesses was within one percent of the
actual weight of the ox. Nobody in the crowd knew the weight of the ox, but the
crowd as a whole was remarkably precise in their estimate. (The ox weighed 1198
pounds—the average guess was 1207 pounds.)
Journalist James Surowiecki wrote a book about this
phenomenon called The Wisdom of Crowds and it is a good and fascinating
read. Now that so many people have access to the Internet, researchers are
designing studies to more clearly delineate just what sorts of questions are
good ones to ask the crowd and what sorts of questions are answered better by
an expert or two.
Social Psychologist Phil Tetlock from the University of
Pennsylvania has started an online prediction study called The Good Judgment Project, in which he collects predictions about specific geopolitical
questions. There were more than 7000 forecasters signed up for the Good
Judgment Project last year. It is being run as part of the Aggregate Contingent
Estimation program of the Office of Incisive Analysis at the Intelligence
Advanced Research Projects Agency. One goal of the project is to find out if
average people can make predictions about geopolitical affairs as well as, or
better than, experts.
Here are a few sample questions from the many dozens
forecasters are currently weighing in on:
Between 4 February
and 30 April 2015, what will be the lowest end-of-day spot price per dry metric
ton of 62% Fe iron ore?
When will France deliver a Mistral-class ship to Russia?
When will France deliver a Mistral-class ship to Russia?
At the start of the prediction season, each participant is
given $50,000 to invest in various answers to the questions. Obviously, the
dollars are not real. (My smartass daughter calls them Dork Dollars.) Some
questions are simple yes/no propositions while others offer a range of answers
that are often split by date or by quantity. It might not sound like it to you, but this project is
totally addictive.
I am, and always have been, a news junkie. That is why I love listening to NPR’s WaitWait Don’t Tell Me and it is why I spend far too much of my down time
researching obscure topics like the Antey-2500 anti-ballistic missile systems
from Russia and the HSBC China Services Purchasing Managers’ Index.
At least, I
used to.
When the season began I was frequently in the Top 20
money-makers in the “league.” Sometimes, I would bounce up into the Top Ten.
When I would crow to Isabel and Erica about an especially clever bet, Isabel
would give me a withering look and ask how many Dork Dollars I had won.
This all came to an end in January. I came across a
proposition that seemed like such a sure thing that I bet every single Dork Penny
I had on it. At the time I was ranked in the Top 20 predictors in my league of
359. The question is this:
When will France deliver a Mistral-class ship to Russia?
- · Before 1 February 2015
- · Between 1 February 2015 and 31 March 2015
- · Between 1 April 2015 and 31 May 2015
- · Not before 1 June 2015
Not to bore you with the details of my (so-far) faulty
reasoning, but I bet heavily—as in, every stinking Dork Dollar I had—on the
fact that the French would indeed deliver a ship before June 1st.
But then all hell broke loose in Ukraine and the French decided to punishRussia and to put the delivery of the Mistral-class helicopter carriers on
hold.
So, for well over two months I have been unable to withdraw
my money from the bet I have made, since to do so would leave me with nothing
left—not one single Dork Dollar to my name. And because all of money is tied up
waiting for France to make up its mind about these boats, I don’t have any
other Dork Dollars to bet on other questions. One of the greatest daily pleasures
in my (admittedly-limited) life has been taken from me. This stupid question
has been my Waterloo.
I have been reduced to setting up a Google Alert that sends
me an e-mail any time a story appears anywhere in the world including the terms
“Mistral, France, Russia.” You might not be surprised to learn that these
alerts hardly ever come.
The question will not be resolved until either France
delivers a ship or June first comes without a delivery. Until then, I am stuck watching from the
sidelines as softball questions come and go—things I KNOW I could nail if only
I had some Dork Dollars available. As things stand, I am now in 359th
place out of 359 predictors.
Yep—dead last.
But my bet is so large, if the French do deliver a
Mistral-class ship to Russia before June 1st, I will climb to #8.
If you want to help, you can write to Francois Hollande and
tell him to let bygones be bygones and deliver that ship! (To send him a note, click here.) I
appreciate any help you can give. Maybe you could spare a few Dork Dollars…?
