I guess he's changed his mind!
Really interesting coming from a guy who wrote this in 2003...
Review Why Societies Need Dissent...shows that demands for lock-step conformity are wrong and uninformed thinking. Sunstein's important new study is filled with empirical evidence of the significance of opposition, found in his compelling explanations of the need for, and benefits of, disagreement. Sunstein reveals that, in fact, the influence of dissenters is for the better, be it with courts, juries, corporate boardrooms, churches, sports teams, student organizations or faculties, not to mention 'the White House, Congress and the Supreme Court...during times of both war and peace.' --John W. Dean (Los Angeles Times Book Review )
