Now, Huntigton expands on his article, explores further the issues he raised then, and develops many new penetrating and controversial analyses. In the article, he posed the question whether conflicts between civilizations would dominate the future of world politics. In the book, he gives his answer, showing not only how clashes between civilizations are the greatest threat to world peace but also how an international order based on civilizations is the best safeguard against war.

    The text draws from political science, public administration, economics, decision analysis, and social and political theory.

    Sunstein shows that organizations and nations are far more likely to prosper if they welcome dissent and promote openness. Attacking "political correctness" in all forms, 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.Sunstein casts new light on freedom of speech, showing that a free society not only forbids censorship but also provides public spaces for dissenters to expose widely held myths and pervasive injustices. He provides evidence about the effects of conformity and dissent on the federal courts. The evidence shows not only that Republican appointees vote differently from Democratic appointees but also that both Republican and Democratic judges are likely to go to extremes if unchecked by opposing views. Understanding the need for dissent illuminates countless social debates, including those over affirmative action in higher education, because diversity is indispensable to learning.Dissenters are often portrayed as selfish and disloyal, but Sunstein shows that those who reject pressures imposed by others perform valuable social functions, often at their own expense. This is true for dissenters in boardrooms, churches, unions, and academia. It is true for dissenters in the White House, Congress, and the Supreme Court. And it is true during times of war and peace.

    Through statistics like these, we feel that we understand our fellow citizens. But remarkably, such data now woven into our social fabric became common currency only in the last century. Sarah Igo tells the story, for the first time, of how opinion polls, man-in-the-street interviews, sex surveys, community studies, and consumer research transformed the United States public.Igo argues that modern surveys, from the Middletown studies to the Gallup Poll and the Kinsey Reports, projected new visions of the nation: authoritative accounts of majorities and minorities, the mainstream and the marginal. They also infiltrated the lives of those who opened their doors to pollsters, or measured their habits and beliefs against statistics culled from strangers. Survey data underwrote categories as abstract as the average American and as intimate as the sexual self.With a bold and sophisticated analysis, Igo demonstrates the power of scientific surveys to shape Americans sense of themselves as individuals, members of communities, and citizens of a nation. Tracing how ordinary people argued about and adapted to a public awash in aggregate data, she reveals how survey techniques and findings became the vocabulary of mass society and essential to understanding who we, as modern Americans, think we are.
