Public Opinion is a book by Walter Lippmann, published in 1922. It 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.[1] The detailed descriptions of the cognitive limitations people face in comprehending their sociopolitical 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.
