On Public Opinion

Walter Lippmann asked, in 1922, a question that has only grown more urgent: how can the people govern themselves if they cannot actually know the world they are trying to govern? Public Opinion is his unsettling examination of the gap between the world outside and the pictures in our heads, between reality and the simplified, secondhand images of it that we carry around and act upon. It is one of the foundational works of media criticism, written before radio and television, and it diagnosed problems that the centuries since have only deepened.

Lippmann's starting point is that the modern world is far too large, complex, and distant for any citizen to know directly. We cannot personally witness the workings of government, the conditions in faraway places, the forces shaping events. Instead we depend on reports, on the press, on others' accounts, and on the mental shortcuts Lippmann famously called stereotypes, the prefabricated pictures through which we make a manageable, simplified map of an unmanageably complex reality. We act not on the world as it is but on the world as it has been represented to us and as we have arranged it in our minds, and the fit between the two is often poor.

This poses a deep problem for democratic theory. Self-government assumes a public capable of forming sound judgments about public affairs. But if the public's picture of those affairs is necessarily partial, secondhand, and shaped by whoever controls the flow of information, then the foundation of democratic decision-making is shakier than the comfortable theory allows. Lippmann was skeptical that ordinary citizens, occupied with their own lives and dependent on imperfect information, could master the complexity that modern governance required, and the book wrestles seriously with what that means for the ideal of popular rule.

Lippmann's own conclusions tended toward a reliance on experts and a more limited role for mass opinion, and that elitist drift is one a democratic reader should engage critically; others, notably John Dewey, answered him by insisting that the remedy for the defects of democracy was more and better democracy, not less. That argument between them is one of the great debates about self-government in the media age, and it is still live. But whatever one concludes, Lippmann's diagnosis of the problem remains penetrating and indispensable.

The book belongs in this library because the relationship between information, media, and self-government is among the permanent questions of the republic, and Lippmann framed it more clearly than anyone before him. It sits at the head of the press-and-media cluster on these shelves, from Orwell and Postman to the modern works on truth and propaganda. Public Opinion is public domain and freely available. Read it for the enduring problem at the heart of democracy: that a people can only govern a world they are able to know, and that knowing it has never been simple.
