Infotopia

In Infotopia, Cass Sunstein examines methods for pooling information from many minds, including statistical averages, deliberation, prediction markets, and Internet-based collaboration such as wikis and blogs.

He highlights the strengths of collective intelligence, like the wisdom of crowds, while critiquing pitfalls such as groupthink, biases, and information cascades that undermine traditional group processes.

The book offers cautious optimism about digital tools enabling better knowledge aggregation for businesses, governments, and individuals.
