In this volume, political psychologists take a hard look at political psychology. They pose and then address, the kinds of tough questions that those outside the field would be inclined to ask and those inside should be able to answer satisfactorily. Not everyone will agree with the answers the authors provide and in some cases, the best an author can do is offer well-grounded speculations. Nonetheless, the chapters raise questions that will lead to an improved political psychology and will generate further discussion and research in the field. The individual chapters are organised around four themes. Part I tries to define political psychology and provides an overview of the field. Part II raises questions about theory and empirical methods in political psychology. Part III contains arguments ranging from the position that the field is too heavily psychological to the view that it is not psychological enough. Part IV considers how political psychologists might best connect individual-level mental processes to aggregate outcomes.
