Book excerpt: Building on and reaching beyond themes in the work of Philip Converse, one of the pioneers in the study of public opinion, Studies in Public Opinion brings together a group of leading American and European social scientists to explore a number of new factors, with a particular emphasis on the structure of political choices. In twelve chapters that reflect different perspectives on how people form political opinions and how these opinions are manipulated, this book offers an unparalleled view of the state-of-the-art research on these important questions as it has developed on two continents.
