Can crowdsourcing help find the missing Malaysia Airlines flight #MH370?

On SciCast, we’ve posted three questions about the missing plane. Can crowdsourcing help to locate it?

Dr. Charles Twardy, Project Principal, explains the different ways to crowdsource a search. “When a community turns out to help look for a lost child, that’s crowdsourcing,” he says. “The community volunteers typically aren’t as well-prepared as the search teams, but when directed by experienced Field Team Leaders, they can greatly extend the search effort. Similarly, experimental micro-tasking sites like TomNod.com let volunteers help search piles of digital images. Call it the effort of the crowd. SciCast is about the wisdom of the crowd: weighing the vast amounts of uncertain and conflicting evidence to arrive at a group judgment, of say the relative chances of several regions or scenarios. This could be as simple as an average - a robust method with much to recommend it when judgments are independent.  Or it could be something more advanced, like SciCast’s combinatorial prediction market.  A market reduces double-counting, and may be better suited to the case where most of us are just mulling over the same information, but a few have real insight. The trick is to find a large and diverse crowd, and persuade them to participate.”

Related Scenarios

Have you explored Related Forecasts yet?  The SciCast Team frequently adds new questions and new links between questions. The links create clusters of related questions supporting “what-if” forecasts.  We will be showcasing some of those here on the blog.

For example, below we see part of the network linking three clusters of questions: Arctic sea ice, the GBO-4 biodiversity reports, and the Pacific sardine population.

An arc (an arrow leading from one question to another) indicates that we think the outcome of one question might influence the other.  Questions connected by arcs will usually appear in each other’s “Related Forecasts” section.  For example, “GBO-4 Biomes” will appear for “Arctic sea ice extent” and vice versa.  Your biome forecast can depend on sea ice extent: presumably a loss of sea ice reduces that biome.
