Aggregating information was not enough to predict the future —this time. Our prediction exchanges won’t issue any statement about it: They will keep it under the rug. When their prediction markets succeed, they brag about it in the media. But when prediction markets fail miserably, it is a deafening silence out there. The “wisdom of crowds” is of interest to them only when chance turns their way. Pitiful.

Prediction markets provide the best objective forecast, and they respond faster to new information than the mass media —but slower than the vertical/local media do (since aggregating information takes a little time). I like that, and if you read Midas Oracle, that means you like it too. But it is overall a small benefit. There is no case for running out there and selling $400-a-seat conferences —hyping that prediction markets can run organizations and governments.
