Abstract

In this chapter, the authors explore the causes and consequences of the factual divide between Red and Blue America. They propose a three-part account of how such differential beliefs arise or, more precisely, an account of how prescriptive beliefs shape descriptive ones. The authors discuss people’s tendency to selectively expose themselves to ideologically sympathetic people, groups, and media sources also plays a significant role in the development of political conflict. Politics is and in fact should be about moral vision: individuals and political parties offering their unique vision of what is right and wrong for the country and its citizens, and how to realize that vision through public policy.
