5. What is the difference between the
Wisdom of Crowds and Collective Intelligence?
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. 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
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;

13. Collective Intelligence
“networked culture gives rise to new structures of power which stem from the ability of diverse
groups of people to pool knowledge, collaborate through research, debate interpretations, and
through such a collaborative process, reﬁne their understanding of the world.”

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.”
