  6. 6. ...aggregating anonymously produced quantifiable data “There are four key qualities that make a crowd smart. It needs to be diverse, so that people are bringing different pieces of information to the table. It needs to be decentralized, so that no one at the top is dictating the crowd's answer. It needs a way of summarizing people's opinions into one collective verdict. And the people in the crowd need to be independent, so that they pay attention mostly to their own information, and not worrying about what everyone around them thinks.” “the aggregation of information in groups, [results] in decisions that…are often better than could have been made by any single member of the group.” -The Wisdom of Crowds, James Surowiecki

  8. 8. Does the Wisdom of Crowds work for politics? quot;given a large enough and varied population offering up their best estimates of quantity or probability, the average of all responses will be more accurate than any given individual response.quot;(1) quot;The [Intrade] markets offer a great way to track the market-based consensus on political and current events. People put real money on the line in making predictions, which is better than snap judgments in opinion polls or no-stakes views of pundits.quot; Tom Gallagher, ISI Group (1)

  18. 18. Tapping into the wisdom of crowds through game play “What he showed was a mockup of a Star Wars Galaxies medical screen, displaying real medical imagery. Players were challenged to advance as doctors by diagnosing the cancers displayed, in an effort to capture the wisdom of crowds. The result? A typical gamer was found to be able to diagnose accurately at 60% of the rate of a trained pathologist. Pile 30 gamers on top of one another, and the averaged result is equivalent to that of a pathologist — with a total investment of around 60-100 hours per player.” -- Ralph Koster
