The essays contained in this volume address three important and interrelated themes in the theory and practice of democratic politics: the use of information short cuts in political decision making; the role of deliberation in citizens' attitude and opinion formation and the pathways to civic and political participation. Drawing on well-established theory and findings from both political science and psychology each essay provides an interpretative review of research within the topic. Taken together, the essays contribute to our understanding of the complex and context-dependent dynamics of mass politics today, pointing out questions that remain unanswered and promising ways to answer these questions in future research.
