This book investigates the nature and function of shared beliefs within societies, proposing a new framework for understanding collective psychological phenomena. Daniel Bar-Tal synthesizes fifteen years of research to establish a conceptual model for identifying beliefs held in common by entire societies and nations. The work draws upon historical, political, sociological, cultural, and educational examples from diverse societies to demonstrate how social psychology can offer a unique lens on societal structures. It advocates for the integration of insights from other social sciences to enrich social psychological theorizing.

The book is positioned as a significant contribution to the emerging subfield of societal psychology, offering a novel perspective by applying social psychological principles to the study of societies. It aims to provide a unified conceptual framework for understanding collective beliefs, drawing on a wide range of empirical examples. The work is likely to appeal to scholars and students interested in the intersection of social psychology, sociology, and political science, particularly those seeking to understand the psychological underpinnings of societal cohesion and national identity.
