His syndicated column "Today and Tomorrow," featured in the New York Herald-Tribune, reached millions globally and earned him two Pulitzer Prizes.

Lippmann describes it as a subjective mental construct shaped by media, culture, and selective information. Individuals respond to this distorted "world inside their heads" rather than objective reality, creating gaps between perception and truth.

What does Lippmann say about stereotypes in Public Opinion?

He argues stereotypes simplify complex realities but perpetuate biases. They act as cognitive filters, shaping how people interpret events and defend their social identities. This leads to moralized, oversimplified views of public issues.

It refers to the strategic shaping of public opinion by elites using media and symbols. Lippmann contends this engineering is necessary in complex societies but raises ethical concerns about manipulation vs. informed democracy.
