In our previous post (see Fate of Flight 370 … below), we quixotically called for the creation of a single-event prediction market in order to (1) bypass all the rampant speculation regarding the ill-fated Malaysia Airlines flight, which has been missing since 8 March 2014, and (2) determine more rigorously the truth values (i.e. probabilities) of the various conjectures and conspiracy theories surrounding this perplexing mystery. In the absence of an actual prediction market, however, would it be possible to recreate a “virtual” or “shadow” market, one based on, say, the number of tweets, Facebook posts, or Reddit entries in support of a given theory or conjecture? Although this alternative would be crude and would require some automated method for aggregating and sorting through an enormous statistical population consisting of millions of data points, what other rigorous options are there?
