In this timely book, Cass R. Sunstein shows that organizations and nations are far more likely to prosper if they welcome dissent and promote openness.

Sunstein demonstrates that corporations, legislatures, even presidents are likely to blunder if they do not cultivate a culture of candor and disclosure. He shows that unjustified extremism, including violence and terrorism, often results from failure to tolerate dissenting views. The tragedy is that blunders and cruelties could be avoided if people spoke out.
