  • Glossary

    Accuracy goal

    The communication purpose in which the intent of the sender is to convey accurate information for the receiver.

    Accuracy motivation

    A person's drive to learn and process information to gain sufficient confidence that his/her judgments are accurate.

    Action efficacy

    The belief in the effectiveness and efficiency of certain behavior in reducing the risk under consideration.

    Adherence goal

    The communication purpose in which the intent of the sender is to move the receiver's attitudes and actions in the direction desired by the sender.

    Collective efficacy

    Individuals’ belief that the larger group, organization, or community that they belong to is capable of carrying out a chosen course of action.

    Crisis communication

    A specific, unexpected, and nonroutine organizationally based event or series of events that create high levels of uncertainty and threat or perceived threat to an organization's high priority goals.

    Cultivation theory

    The theory of cultivation, proposed by George Gerbner, focuses on the role that television plays in shaping viewer's perceptions of social reality. The theory predicts that those who spend more time watching television will be more likely to view reality in terms of the very images that television portrays.

    Decision from description

    Choices between risky options that are based on symbolic and complete descriptions of options and their probabilities (e.g., graphical representations, numerical representations).

    Decision from experience

    Choices between uncertain options that are based on various sources of experience about possible outcomes and their probabilities (e.g., on-line samples from the options, samples of relevant experience from memory, and samples of relevant vicarious experience).

    Deliberative democracy

    A body of political theory that focuses on the role of public dialogue in decision making about public issues and on which risk communication scholars have drawn insight when designing public engagement mechanisms.

    Deliberative risk delineation

    A procedure for identifying and constructing risk that works from the claim that risk is best delineated in any given case when it is the product of participatory democracy and deliberative decision making.

    Discourse of renewal

    A means by which organizations, after experiencing a crisis, recognize fallacious assumptions or unforeseen vulnerabilities while reestablishing core values.

    Edgework

    High-risk activities undertaken voluntarily that involve a clearly observable threat to one's physical or mental well-being or one's sense of an ordered existence.

    Edgework communities

    Networks of risk takers who assist one another in skill development, build group structures for assessing individual member readiness for high-risk behavior, set controls for less skilled members, and inculcate the value of learning from small failures so that future harms are avoided.

    Ethics

    Coming from the Greek word ethos, which means character, ethics addresses morality questions such as right and wrong or good and evil. Ethical issues in risk communication often entail fair distribution of risks and benefits, empowerment of recipients of risk communication messages, and adequate disclosure of information that enables informed decision making.

    Framing

    The process whereby social movement actors assign meaning to events and circumstances with the intent of mobilizing possible supporters, acquiring the sympathy of bystanders, and demobilizing opponents.

    Fuzzy-trace theory

    A theory that integrates reasoning and decision making in a new way to explain numeracy by distinguishing between meaning-based gist representations, which support fuzzy (yet advanced) intuition, and superficial verbatim representations of information, which support precise analysis.

    Genetic counseling

    The professional provision of assistance and guidance in resolving human problems associated with a genetic disorder or the heightened risk of a genetic disorder in an individual or family.

    Graphical displays of risk information

    Data-driven visual message elements featuring numerical information, such as risk ratios, hazard ratios, and other probabilities; frequency comparisons; and multivariate projections of mortality and morbidity.

    Group polarization

    The tendency of a group to move toward a more extreme position compared with the average individual group member. The direction of the shift is determined by the majority of the members’ predeliberation preferences.

    Illustrative displays of risk information

    Visual messages and visual message features conveying information related to threats, hazards, or risk avoidance that are not numerical in nature, such as pictures of people alongside textual information to influence perceptions of risk susceptibility, grotesque images that convey risk severity, as well as sequential images that provide instructions about how someone might reduce his or her risk by taking safety precautions (e.g., airplane safety guides) and other visual representations of risk that are nonnumeric and have indexical qualities.

    Impression involvement

    The extent to which one is concerned with other people's impression of his or her publicly expressed attitude.

    Information dissemination

    The relative reach, rapidity, and timeliness of information sharing. Social media can provide a means of distributing information about risk to large audiences in a quick and timely manner.

    Information processing

    The mental process of manipulating, storing, and retrieving information. The process may or may not integrate information into existing mental models already maintained by the individual.

    Information seeking

    An effort—usually conscious—to acquire information in response to a need or gap in knowledge.

    Information subsidy

    Information provided to journalists, without any investment of money or effort on the journalists’ part, in the hope of influencing what they cover and how they cover it; press releases distributed by public relations staff fall into this category.

    Informed decision making

    Primarily discussed in health care settings, informed decision making aims at increasing individuals’ participation in decision making at a level they desire. Supported by adequate information, informed decision making promotes decisions that are consistent with individuals’ values and preferences.

    Institutional efficacy

    Belief that large societal institutions are fair, just, and reliable.

    Interactivity

    The degree to which stakeholders in an organization can communicate directly with one another. Interactivity is an affordance of social media that can be used by organizations or governments to communicate with their audience(s) in a two-way fashion that allows for information exchange.

    Media framing

    Involves the process of selectively emphasizing one aspect or dimension of a complex subject over another. Media “frames” set a specific train of thought in motion, communicating why an issue might be a problem or pose a threat, who or what might be responsible, and what should be done.

    Media priming

    The issues or events at any given moment that are receiving the greatest amount of media attention often serve as the criteria by which the public evaluate the performance and credibility of a political leader, government agency, scientific organization, or corporation.

    Media routines

    The set of professional practices typical of day-to-day journalistic work by which journalists and editors choose news topics, create narrative stories framed in particular ways out of “raw” information, and select sources and statements to include in those stories.

    Narratives

    Stories that connect actions and events involving characters with thematic and temporal sequences.

    Numeracy

    The ability to understand and use numbers.

    Outcome involvement

    The extent to which the issue under consideration is important to one's goals.

    Personal risk perception

    Judgments that one is facing a threat.

    Probability neglect

    The idea that probabilities are ignored when judging consequences of decisions. Affect-rich presentations of risk can evoke probability neglect in risk perception.

    Public engagement

    A broad area of study focused on the procedures through which decision makers and other actors communicate around current or potential policy question. Health and environmental risks are common topics for public engagement.

    Reference class

    When determining the probability of a negative event or outcome, as a first step, a risk communicator must begin by choosing a reference class. The reference class determines which numbers will be presented. For example, the frequencies of plane crashes can be computed by month, year, or decade; air company; category of distance traveled; or plane size. All these categories specify different reference classes. Often, misunderstandings about the meaning of a particular risk message can be attributed to confusion about the identity of the reference class.

    Rhetoric of risk

    A subfield of scholarship grounded in the assumption that risk is, to some extent, discursively constructed and dedicated to exploring the symbolic constitution of risk over time and in specific historical moments.

    Risk

    Defined as the probability and the magnitude of harm, where harm refers to threats to humans and things they value. Risks are generally measurable, that is, outcomes and their probabilities are known.

    Risk as feeling

    The hypothesis that risks are experienced affectively. These feelings intuitively influence how dangerous risks are perceived.

    Risk perception

    Refers to the subjective assessment of the probability and the magnitude of harm. Risk perceptions include people's beliefs, attitudes, and judgments regarding risky events. Theories of risk perception acknowledge that the interdependence of the individual with societal and cultural contexts may amplify or attenuate individual perception.

    Risky shift phenomenon

    The tendency of groups to form riskier decisions than their average group member.

    Shared and unshared information

    Shared information refers to information items that are known to several group members prior to group deliberation. Unshared information refers to items that are only known to individual group members.

    Societal risk perception

    Judgments that the society or collective at large is facing a threat.

    Societal risk reduction action

    Behaviors to reduce the threat faced by the larger society by changing the conditions and contexts surrounding the threat, such as willingness to support changes in policies regarding risk; to voice opposition or support for social changes; to donate time, money, and other resources that can be utilized in efforts to facilitate changes; and to lower barriers to changes in social, political, and economic environments.

    Spiral of silence

    The spiral of silence, authored by Elisabeth Noelle-Neumann, is a communication theory describing the process by which a point of view can become dominant in society. The theory posits that the willingness of an individual to express his or her opinion is a function of how he or she perceives the climate of opinion. Out of an innate fear of isolation, people tend to remain silent when they believe that their views are in the minority, but they are more vocal when they believe that their opinions are similar to those of the majority.

    Survival rate

    The proportion of patients who are alive after a fixed period (e.g., 5 or 10 years) after they have been diagnosed with a disease. Survival rates are misleading as a measure of how well screenings work. Survival rates will increase whenever cancers are diagnosed earlier, even if the time of death is not postponed.

    Transactional communication

    In interpersonal communication, each individual simultaneously influences and is influenced by the other. It is within this mutually constructed context that the individuals relate to each other.

    Uncertainty

    In contrast to risk, uncertainty is not measureable as either the probabilities of outcomes and/or the outcomes are unknown. A more relaxed definition allows for a quantification of uncertainty in form of confidence intervals, ranges, or expert confidence ratings.

    Uncertainty management theory

    Uncertainty theories focus on how individuals assess, manage, and cope with ambiguous and complex situations inherent in risk communication. Uncertainty management theory is one of the most widely used uncertainty theories, and it posits that uncertainty engenders other emotions besides anxiety and that people are not always motivated to decrease their uncertainty.

    Value involvement

    The extent to which the issue under consideration is related to one's perspective on how the world should operate.
