I'm not sure it's at all analogous, but I have noticed over the years that when a lot of pundits pick the same cinderella in the NCAA tournament, that team tends to advance. Any one pundit is more likely to be wrong than right, but if you put enough of them together, the consensus can be predictive. It's sort of like ants building an anthill, or the "ask the audience" lifeline on Who Wants to Be a Millionaire. I think the concept is called "emergence." Then again, it could just be a bandwagon effect, in which case it is not at all predictive of anything.
