- IDEA 1 OF 8
We act on images, not reality
Lippmann argues that people cannot directly know the vast world beyond their experience.
Instead, they act on simplified mental images, which may differ greatly from reality. In his view, this gap is a basic problem for public life.
- IDEA 2 OF 8
We live in a pseudo-environment
Lippmann describes the pseudo-environment, the picture of the world that each person builds from limited information.
People respond to this picture, not to reality itself. Because each person's picture differs, people can sincerely disagree about what is happening.
- IDEA 3 OF 8
Stereotypes simplify the world
Lippmann popularised the word stereotype for fixed mental pictures we use to make sense of people and events.
They save effort but can mislead. Once a fixed idea is in place, we tend to notice only what fits it.
- IDEA 4 OF 8
Information is limited
Lippmann explains that censorship, privacy, time and attention all limit what people can learn.
Most citizens cannot follow complex public affairs. Even an honest and busy citizen has only a small part of the facts available.
- IDEA 5 OF 8
Consent can be manufactured
Lippmann argues that leaders can shape public opinion through careful persuasion.
He saw this as a growing feature of modern politics. In his view, skilled communicators can steer what large groups believe without the groups noticing.
- IDEA 6 OF 8
The press cannot do it all
Lippmann argues that newspapers cannot provide citizens with all the knowledge they need.
News is selective and incomplete. A paper reports what happens at a certain moment, so deeper trends can pass unseen.
- IDEA 7 OF 8
Democracy faces a problem
Lippmann questions the idea that ordinary citizens can form sound opinions on every issue.
This challenged traditional democratic theory. He doubted that every voter could judge every question well, and thought this needed a fresh response.
- IDEA 8 OF 8
Experts should inform decisions
Lippmann proposes organised intelligence, bodies of experts who gather facts for decision-makers.
His view sparked a famous debate with John Dewey. In his view, these experts would give leaders clear facts, while Dewey wanted more public involvement.
