Introduction


In January 1903, S.S. McClure, the founder and editor of the popular mass-circulation magazine McClure's, drew his readers' attention to the "coincidental" appearance of three articles in that month's issue--one, by Lincoln Steffens, on corruption and machine politics in Minneapolis; the second, an installment in Ida Tarbell's continuing history of Standard Oil; and the third, a piece by Ray Stannard Baker critical of organized labor's attempts to keep non-union men from working. These were not the first investigative pieces exposing what McClure described as a "contempt for law" in American institutions. But what McClure had discovered was the salience of these issues to his readers; what he glimpsed was the influence that periodicals like his could have on the public's social consciousness. "Capitalists, workingmen, politicians, citizens--all breaking the law, or letting it be broken," he editorialized. "Who is left to uphold it? . . . There is no one left; none but all of us." What followed was a uniquely 20th-century phenomenon: a public crusade, fueled by the popular press, producing within a decade sweeping reforms of municipal government and state and federal civil service, electoral reform, pure food and drug regulation, antitrust legislation, and myriad other "progressive" social reforms. With no specific agenda of its own, McClure's nonetheless launched a new era in mass communication and social agenda-setting.

Nearly 80 years later, in December 1981, an editorial in the New England Journal of Medicine directed readers' attention to another coincidence--independent reports from the field about the appearance of rare opportunistic illnesses in young homosexual men. What have we learned since McClure's day about how the media shape the social agenda, for good or ill, or influence the public's capacity to take effective action? In the history of the AIDS crisis, did the popular media contribute to unconscionable inaction in the early days by relegating the story to the margins of social deviance? Or did they ultimately help mobilize public opinion around an extraordinarily difficult social issue? Or did they do both? What do we know now about harnessing the power of mass communication to influence public attitudes or change behavior? Are there lessons to be drawn from campaigns designed to alter health-compromising behaviors, such as those against smoking or drunk driving?

In October 1993, The Annenberg Washington Program and the Harvard School of Public Health's Center for Health Communication convened a group of scholars, journalists, activists, and public officials to address these questions. The conference was funded by The Annenberg Washington Program, The Alfred P. Sloan Foundation, and The John D. and Catherine T. MacArthur Foundation. The meeting, initiated by Jay Winsten, Director of the Center for Health Communication of the Harvard School of Public Health, had two primary tasks. The first was to take stock of what we know about these questions, generically, as Harvard Professor Mark Moore explained in the opening session:

We hope to learn how mass communication shapes . . . society's ability to deal with its problems; gets issues on the public and governmental agenda; reinforces or alters norms . . . and attitudes within the general population; and imparts specific information to specific individuals that changes the way those individuals behave.

The group's second task was to bring these insights to bear on the particular effort now underway to address the problem of violence in our society.

For two days, the participants reviewed scholarly findings, reflected on their own professional experiences concerning AIDS, smoking, and drunk driving, and considered how the power of mass communication could be marshalled to respond effectively to the problem of violence. The report that follows is based on those deliberations.
