Review

"This extraordinary work synthesizes the latest in how we know, with the latest in what the web has become to map more compellingly than any other book the promise and risk of the information society. As with everything Sunstein writes, this beautiful and clear book has something to teach the experts, and lots to teach the rest of us."--Lawrence Lessig, author of Free Culture and The Future of Ideas
"Infotopia is a persuasive and sophisticated meditation on the ways in which the Web is not just living up to its early hype, but transcending it. Cass Sunstein has given us a brilliant integrative view of how the distributed users of the Internet can band together to produce extraordinary work--along with the circumstances that best give rise to deliberation rather than groupthink."--Jonathan Zittrain, Professor of Internet Governance and Regulation, Oxford University
"Cass Sunstein's new book is a lively illustration of emerging mechanisms for collective rationality never anticipated in the classic writings of Madison, Marx, or Milton (Friedman). Neither a utopian nor a Luddite, Sunstein provides just the right mix of enthusiasm and caution. Ironically, in arguing for the tremendous potential of the group mind, Sunstein demonstrates a command of law, social science, and computer science rarely found in any individual author--and produces a very fun read."--Robert MacCoun, Professor of Public Policy and Law, University of California at Berkeley
"In our knowledge-based world, extracting useful information from society is more important than ever. Sunstein convincingly reveals the limitations of popular processes like deliberation while showing how collectives--under certain conditions--can effectively solve many problems. An engaging read, full of eye-opening examples,Infotopia shows how and why our efforts to harness knowledge must evolve."--Michael J. Mauboussin, Chief Investment Strategist, Legg Mason Capital Management and author of More Than You Know: Finding Financial Wisdom in Unconventional Places
"Sunstein, one of the biggest of America's internet big thinkers, has written an intriguing new book in which he argues that Hayek's insights about the genius of markets are equally true of the internet. Sunstein argues, for example, that sharing scientific information online would cure some of the worst problems of the US patent system and foster innovation much more efficiently than costly patent litigation. Sunstein recognizes all the potential flaws of such collaborative projects. Groupthink can be dangerous. But, says Sunstein, the wisdom of the many is a great thing, and sharing knowledge online can lead to remarkable advances for companies, for governments and for the rest of us."--Patti Waldmeir, Financial Times
"A survey of the evidence on how information technology affects political debate and institutional decision making. The result is a vivid, readable, and informative work of empiricist skepticism--a show-me-the-money guide to what soars and what stumbles from the stable of Internet dreams."--Jedediah Purdy, American Prospect, Duke University

Product Description

The rise of the "information society" offers not only considerable peril but also great promise. Beset from all sides by a never-ending barrage of media, how can we ensure that the most accurate information emerges and is heeded? In this book, Cass R. Sunstein develops a deeply optimistic understanding of the human potential to pool information, and to use that knowledge to improve our lives.

In an age of information overload, it is easy to fall back on our own prejudices and insulate ourselves with comforting opinions that reaffirm our core beliefs. Crowds quickly become mobs. The justification for the Iraq war, the collapse of Enron, the explosion of the space shuttle Columbia--all of these resulted from decisions made by leaders and groups trapped in "information cocoons," shielded from information at odds with their preconceptions. How can leaders and ordinary people challenge insular decision making and gain access to the sum of human knowledge?

Stunning new ways to share and aggregate information, many Internet-based, are helping companies, schools, governments, and individuals not only to acquire, but also to create, ever-growing bodies of accurate knowledge. Through a ceaseless flurry of self-correcting exchanges, wikis, covering everything from politics and business plans to sports and science fiction subcultures, amass--and refine--information. Open-source software enables large numbers of people to participate in technological development. Prediction markets aggregate information in a way that allows companies, ranging from computer manufacturers to Hollywood studios, to make better decisions about product launches and office openings. Sunstein shows how people can assimilate aggregated information without succumbing to the dangers of the herd mentality--and when and why the new aggregation techniques are so astoundingly accurate.

In a world where opinion and anecdote increasingly compete on equal footing with hard evidence, the on-line effort of many minds coming together might well provide the best path to infotopia.

4.0 out of 5 stars Complements Wikinomics, Solid but Incomplete, January 17, 2007

By	Robert D. Steele (Oakton, VA United States) - See all my reviews (TOP 50 REVIEWER)

Amazon Verified Purchase

I was initially disappointed, but adjusted my expectations when I reminded myself that the author is at root a lawyer. The bottom line on this book is that it provided a very educated and well-footnoted discourse the nature and prospects for group deliberation, but there are three *huge* missing pieces:

1) Education as the necessary continuous foundation for deliberation

2) Collective Intelligence as an emerging discipline (see the Innovators spread sheet at Earth Intelligence Network); and

3) No reference to Serious Games/Games for Change or budgets as a foundation for planning the future rather than predicting it.

In the general overview the author discusses information cocoons (self-segregation and myopia) and information influences/social pressures that can repress free thinking and sharing.

The four big problems that he finds in the history of deliberation are amplifying errors; hidden profiles & favoring common or "familiar" knowledge; cascades & polarization; and negative reinforements from being within a narrow group.

Today I am missing a meeting on Predictive Markets in DC (AEI-Brookings) and while I regret that, I have thoroughly enjoyed the author's deep look at Prediction Markets, with special reference to Google and Microsoft use of these internally. This book, at a minimum, provides the very best overview of prediction markets that I have come across. At the end of the book is an appendix listing 18 specific predictions markets with their URLs.

The author goes on to provide an overview of the Wiki world, and is generally very kind to Jimbo Wales and Wikipedia, and less focused on the many altneratives and enhancements of the open Wiki. It would have been helpful here to have some insights for the general reader on Doug Englebart's Open Hypertextdocument System (OHS) and Pierre Levy's Information Economy Meta Language (IEML), both of which may well leave the mob-like open wiki's in the dust.

Worthy of note: Soar Technology is quoted as saying that Wikis cut project development time in half.

The book draws to a close with further discussion of the challenges of self-segregation, the options for aggregating views and knowledge and for encouraging feedback, and the urgency of finding incentives to induce full disclosure and full participation from all who have something to contribute.

This book excels in its own narrowly-chosen domain, but it is isolated from the larger scheme of things including needed educational changes, the importance of belief systems as the objective of Intelligence and Information Operations (I2O), the role of Serious Games/Games for Change, and the considerable work that has been done by Collective Intelligence pioneers, who just held their first convergence conference call on 15 January 2007.

Final note: the author uses NASA and the Columbia disaster, and CIA and the Iraq disaster, as examples, but does not adequately discuss the pathologies of bureaucracy and the politicization of intelligence and space. As a former CIA employee who also reads a great deal, I can assert with confidence that CIA has no trouble aggregating all that it knew, including the reports of the 30 line crossers who went in and then came back to report there were no Weapons of Mass Destruction. CIA has two problems: 1) Dick Cheney refused to listen; and 2) George Tenet lacked the integrity to go public and go to Congress to challenge Dick Cheney's malicious and impeachable offenses against America (see my reviews of "VICE" and of "One Percent Doctrine" on Cheney, and my many reviews on the mistakes leading up to and within the Iraq war). See also my reviews of "Fog Facts" and "Lost History" and Gaddis' "The Landscape of History."

To end on an upbeat note, what I see in this book, and "Wikinomics" and "Collective Intelligence" and "Tao of Democracy" and my own "The New Craft of Intelligence: Personal, Public, & Political," is a desperate need for Amazon to take on the task of aggregating books and building out from books to create social communities where all these books can be "seen" and "read" and "understood" as a whole. We remain fragmented in the production and dissemination of information, and consequently, in our own mind-sets and world-views. Time to change that, perhaps with Wiki-books that lock-down the original and then give free license to apply OHS linkages at the paragraph level, and unlimited wike build-outs. That's what I am in Seattle to discuss this week.

3.0 out of 5 stars Read the 1/5 about deliberation, leave the rest., June 13, 2007

By	The Dilettante "Dilly!" - See all my reviews (TOP 1000 REVIEWER)

Amazon Verified Purchase

In the 1960's, legal scholars discovered what the rest of us always knew: that pure legal scholarship is really, really boring. Law and economics demonstrated that a multidisciplinary approach could breath fresh life into the corpse of law. Then, suddenly, all the rock star law professors were interdisciplinarians. And along with this devaluation of pure legal thought came a general loss of intellectual rigor. By the 1990's, celebrity law professors were becoming like journalists with really good grades, each writing outside of his or her area of competence with an astonishing self-confidence. Richard Posner, who was on relatively solid ground in economics, crowned himself an expert on military intelligence. Lawrence Lessig wrote a whole series of books without any thesis or logical argument. And this new breed of scholar seemed to be in a race to publish as much as possible as quickly as possible, without regard for quality.

I have always thought that Cass Sunstein epitomizes the worst of this trend. He seems to rush a book into print every six months, and with each new work drifts further and further away from "law." But after hearing him on Russ Roberts' fantastic EconTalk podcast, I was genuinely dying to read this book. The topics chosen are all fascinating, and no one has really treated them all under one roof before.

The problem is that, once again, Sunstein has given short shrift to these topics. All of them, with the exception of group deliberation, has been covered better elsewhere. Where Sunstein is not stealing the limelight from people like Robin Hanson (prediction markets) he is rehashing the pop science books of people like James Surowieki (statistical group judgments).

The reason this book gets three stars instead of zero is that the material on bias in group deliberation is genuinely insightful and original. In brief: deliberative bodies make very poor decisions, due to a whole slew of biases and feedback loops. When Sunstein suggests that we reform deliberative bodies, generally, to incorporate anonymous voting and minority voices, he is offering something genuinely useful. (Interestingly, at one point in the podcast mentioned above, Sunstein all but admits that this was initiated as a book about deliberation and that the project was changed to incorporate the other topics in media res. This explains a lot.) Read it for the bits on deliberation, but be prepared to be bored and underwhelmed by large portions.

4.0 out of 5 stars Like The Wisdom of Crowds without the hype , July 18, 2008

By	Peter McCluskey (Mountain View, CA USA) - See all my reviews (REAL NAME)

This review is from: Infotopia: How Many Minds Produce Knowledge (Paperback)

There's a lot of overlap between James Surowiecki's The Wisdom of Crowds and Infotopia, but Infotopia is a good deal more balanced and careful to avoid exaggeration. This makes Infotopia less exciting but more likely to convince a thoughtful reader. It devotes a good deal of attention to conditions which make groups less wise than individuals as well as conditions where groups outperform the best individuals.
Infotopia is directed at people who know little about this subject. I found hardly any new insights in it, and few ideas that I disagreed with. Some of its comments will seem too obvious to be worth mentioning to anyone who uses the web much. It's slightly better than Wisdom of Crowds, but if you've already read Wisdom of Crowds you'll get little out of Infotopia.
