Mass Predictions

An interesting article on obtaining a pool of 'experts' making predictions for you. See related post here. It seems that ProbabilityFootball has successfully done what I was talking about in that old post. The most remarkable thing:

Even when we average together the very worst participants — those participants who actually scored below zero in the contest — the resulting predictions are amazingly good.

It seems that it would be worthwhile to try something like this on the stock market. However, it would probably be a lot harder to get people making predictions about the stock market since not so many would care. Also, I keep thinking that with football it is more reasonable that people do well because they can make educated guesses which is harder to do for the stock market. I wonder how educated the pool of 'experts' needs to be in order to produce decent results. Heck... I might even try to do it...
