Introduction to Prediction Markets
When you gather a suitably diverse group of people together, ask them a question and average their answers, the result tends to be more accurate than the result of any one person including experts. The implication of this, is that the crowd as a whole can make better informed judgements than traditional experts. There just needs to be an ideal way to extract those tiny bits of relative information from individuals in a consistent manner. Enter the prediction market.
