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.
Walter Lippmann was an American writer, reporter, and political commentator famous for being among the first to introduce the concept of Cold War, coining the term "stereotype" in the modern psychological meaning, and critiquing media and democracy in his newspaper column and several books.
