On My heart’s in Accra Ethan Zuckerman reviews Cass Sunstein’s book “Infotopia”, which discusses how the internet changes group decision making processes. Zuckerman writes:
… In his new book, Infotopia, [Sunstein’s] become a cyber-enthusiast to an extent that would have been hard to imagine a few years ago. Specifically, he’s excited about the ways new online tools make it possible for groups of people to assemble information and accumulate knowledge. He’s become a devotee of Friedrich Hayek, the Austrian economist who saw markets, first and foremost, as a way to aggregate information held by a large group of people. There’s ample evidence that Hayek was right in an examination of the failure of planned economies – smart men sitting in a room do a far worse job of setting the price of copper ore or bread than the collected actions of thousands of consumers, iterated over time.
Markets aren’t the only way to aggregate information from a large group of people. Deliberative groups, where a set of people get together and share the knowledge they have on a problem or an issue, are favored by many political theorists, including Jürgen Habermas, who bases much of his political philosophy on the establishment of a public sphere where deliberation can occur. Sunstein is deeply suspicious of the optimistic claims made for deliberation, and cites a wealth of studies that demonstrate that deliberation, in many cases, leads to bad decisions and the reinforcement of extreme views.
(You can think of Infotopia as a caged deathmatch between Hayek and Habermas, streamed live on the Internet. Habermas taps out somewhere around page 200.)
