Book excerpt: This book illuminates, and ultimately defends, attitudinal hypocrisy within the personal politics of Americans by utilizing statistical analyses within political history, social psychology, public opinion, and political science. Within a simple and parsimonious model of political attitudes, along with a novel method of calculating and operationalizing what attitudinal hypocrisy is, the book argues that the wielding of conflicting attitudes is a necessary characteristic of the American electorate. It uses an innovative multidisciplinary approach to answer some of the most pervasive questions in American politics: Why do conservatives preach the value of economic libertarianism, but decry the lack of government involvement in social issues and the military? Why do liberals extol the virtues of a regulatory economic state, but not a cultural or military state?
