" Collectives can be just as stupid as any individual, and in important cases, stupider. The interesting question is whether it's possible to map out where the one is smarter than the many.

There is a lot of history to this topic, and varied disciplines have lots to say. Here is a quick pass at where I think the boundary between effective collective thought and nonsense lies: The collective is more likely to be smart when it isn't defining its own questions, when the goodness of an answer can be evaluated by a simple result (such as a single numeric value,) and when the information system which informs the collective is filtered by a quality control mechanism that relies on individuals to a high degree. Under those circumstances, a collective can be smarter than a person. Break any one of those conditions and the collective becomes unreliable or worse.

Meanwhile, an individual best achieves optimal stupidity on those rare occasions when one is both given substantial powers and insulated from the results of his or her actions.

If the above criteria have any merit, then there is an unfortunate convergence. The setup for the most stupid collective is also the setup for the most stupid individuals. " --

" The pre-Internet world provides some great examples of how personality-based quality control can improve collective intelligence. For instance, an independent press provides tasty news about politicians by reporters with strong voices and reputations, like the Watergate reporting of Woodward and Bernstein. Other writers provide product reviews, such as Walt Mossberg in The Wall Street Journal and David Pogue in The New York Times. Such journalists inform the collective's determination of election results and pricing. Without an independent press, composed of heroic voices, the collective becomes stupid and unreliable, as has been demonstrated in many historical instances. (Recent events in America have reflected the weakening of the press, in my opinion.)

Scientific communities likewise achieve quality through a cooperative process that includes checks and balances, and ultimately rests on a foundation of goodwill and "blind" elitism — blind in the sense that ideally anyone can gain entry, but only on the basis of a meritocracy. The tenure system and many other aspects of the academy are designed to support the idea that individual scholars matter, not just the process or the collective. " --

" The Wikipedia has recently slapped a crude low pass filter on the jitteriest entries, such as "President George W. Bush." There's now a limit to how often a particular person can remove someone else's text fragments. I suspect that this will eventually have to evolve into an approximate mirror of democracy as it was before the Internet arrived. " --

" Another example of the slow hive problem: There was a lot of technology developed slowly in the millennia before there was a clear idea of how to be empirical, how to have a peer reviewed technical literature and an education based on it, and before there was an efficient market to determine the value of inventions. What is crucial to notice about modernity is that structure and constraints were part of what sped up the process of technological development, not just pure openness and concessions to the collective.

" The illusion that what we already have is close to good enough, or that it is alive and will fix itself, is the most dangerous illusion of all. By avoiding that nonsense, it ought to be possible to find a humanistic and practical way to maximize value of the collective on the Web without turning ourselves into idiots. The best guiding principle is to always cherish individuals first. " --
