Public Opinion [with Biographical Introduction]

Summary:

The book analyzes the influence of mass media and propaganda on democracy and public opinion, arguing that the public is often unable to form accurate views due to the manipulation of information and the inherent limitations of individual cognition. It explores the concept of the "manufacture of consent" and suggests that a specialized class of experts is necessary to manage the flow of information in society.

Key points:

1. Perception Filter: Lippmann explains that people see the world through their own experiences and media, which creates a subjective view that influences opinions and actions.
