The book "Public Opinion" is a critical assessment of functional democratic government, especially of the irrational and often self-serving social perceptions that influence individual behavior and prevent optimal societal cohesion. The detailed descriptions of the cognitive limitations people face in comprehending their socio-political and cultural environments leading them to apply an evolving catalogue of general stereotypes to a complex reality, rendered Public Opinion a seminal text in the fields of media studies, political science, and social psychology.
