Will Philae land successfully on the surface of a comet?
3 Replies
Background
SciCasters are following the ESA’s International Rosetta Mission and counting down the days of the much-anticipated landing of the Philae on a periodic comet known as Comet 67P/Churyumov-Gerasimenko. The latest news from ESA states that it will deploy the Philae to the comet on November 12. http://bit.ly/1DQEAcy
HPV questions have resolved on SciCast
The HPV questions have resolved. There were 52 questions (one for each state) plus six cluster questions and one question about the nation (see trends graph below).
The state questions asked, “What will be the 2013 estimated vaccination coverage of HPV for females aged 13-17 in the state of <State name>.”
State HPV vaccination likely is dependent on the cluster to which the state belongs. We asked forecasters to help to fill in the conditional probability forecasts by using the “Related Forecasts” section after a forecast on the cluster question. Continue reading
The World Cup question has resolved
The question, A young paraplegic Brazilian, assisted by a neurorobotic exoskeleton, will take the ceremonial first kick at the 2014 World Cup in São Paulo, Brazil. How far will the ball travel? has resolved as “Between 1-3 meters”. Our Brier score was 0.326, better than uniform.

SciCast, Bluefin-21, and GeNIe
Reposted with permission from SciCast forecaster Jay Kominek. You can find his blog, hypercomplex.net here.
I’m going to assume you’re familiar with SciCast; if you aren’t, that link is the place to start. Or maybe Wikipedia.
There has been a open question on SciCast, “Will Bluefin-21 locate the black box from Malaysian Airlines flight MH-370?”, since mid-April. (If you don’t know what MH370 is, I envy you.) It dropped fairly quickly to predicting that there was a 10% chance of Bluefin-21 locating MH370. Early on, that was reasonable enough. There was evidence pings from the black box had been detected in the region, so the entire Indian Ocean had been narrowed down to a relatively small area.
Unfortunately weeks passed and on May 29th Bluefin-21’s mission was completed, unsuccessfully. Bluefin-21 then stopped looking. At this point, I (and others) expected the forecast to plummet. But folks kept pushing it back up. In fact I count about 5 or 6 distinct individuals who moved the probability up after completion of the mission. There are perfectly good reasons related to the nature of the prediction market for some of those adjustments.
I’m interested in the bad reasons.
