"Addressing an extremely important topic, this book can generate a new level of understanding about response instability and, more generally, the role of low information voters in democratic governance. It goes a long way to getting us out of a rut in which we have been stuck for a long time.... The editors have done a very good job of pulling together some state of the art scholarship on the topic." - Peter Nardulli, University of Illinois; "This collection is distinguished by the quality of the individual essays and the unity of the themes. Questions of non-attitudes and the effects of political sophistication are central to political psychology, and so no one in the field should miss this book." - Robert Jervis, Columbia University, author of System Effects: Complexity in Political and Social Life"
