Many natural disasters and industrial accidents are not unforeseen; in many cases, scientists and other experts have conducted analyses and communicated the potential risks in advance. When a disaster does occur, journalists and the media react immediately. Politicians and administrators, spurred by this media coverage, then begin to work to change laws and regulations. Finally, representatives from the business sector not only change production processes and products but also invest in new research and public relations: this is done to shape media coverage in the event of another accident or disaster and to inform the public and reach acceptance of risks and uncertainty. A theory of risk communication, however, is only beginning to develop. The term risk communication appeared for the first time in the mid-1980s, as an interdisciplinary field bringing together a wide array of disciplines: economics, sociology, psychology, and communication research (Jungermann, et al. 1988; Lundgreen and McKaien 2013, cited under Communication about Risks). Analyses dealing with risk communication describe and explain (1) what persons communicate in what ways about risks, (2) how the mass media covers risks, and (3) what influences the way the general public receives, understands, and uses risk-related information. Based in the United States and beginning in the late 1960s—and supported by several major industrial accidents (e.g., the Bhopal gas leak and the Chernobyl [see Chernousenko 1991] and the Three Mile Island nuclear meltdowns)—a scientific and political controversy was ignited. Key issues were (1) how experts perceive and assess risks; (2) how journalists, the media, and the general public perceive and evaluate risks based on expert opinion; and (3) if a dialogue between experts and non-experts would result in more acceptance toward the undesirable but inevitable consequences of risks. Risk communication research explores the general public’s concerns regarding important scientific findings, technological innovations, and their social consequences, as well as the skepticism of experts, journalists, and information recipients toward uncertain consequences of technological innovations. These forces can be seen both in media coverage about science and in public-relations materials. Risk communication research emphasizes that basic research and innovations are associated with risks but that these risks are necessary to increase wealth and knowledge.
