"Proponents of democratic decision making usually avert their eyes from the fact that many citizens know little about the issues on which they are asked to make judgments or, even worse, they 'know' things that are factually mistaken. Scott Althaus addresses this problem head-on and finds that variations in knowledge do indeed bias the outcomes of opinion surveys in a troubling way. But not always, and not unavoidably--this is no jeremiad. Instead, Althaus gives sensible, thoughtful, usable suggestions for overcoming problems that most would rather ignore. This is a vitally important book for all who care about both democracy and political fairness." Jennifer L. Hochschild, Harvard University
