Risk is a social construction, and its understanding by information consumers is shaped through interaction with messages, opinions, shared and learned experiences, and interpretations of the characteristics of risk. Social actors and information flows can provide heuristic cues about risks, their relative importance and unimportance, and the attention that an information consumer ought to pay to a particular risk. Social cues can also accentuate particular characteristics of risk, further amplifying or attenuating attention to it and shaping behaviors. This, in turn, can generate secondary and tertiary effects resultant from the public’s reaction to risk. The process of social amplification of risk, therefore, has structural components that include the social elements that get enacted in the process of the translation of risk information. Risk amplification is also affected by message factors, which can dramatize information, increase attention and uncertainty, and generate shared signals and symbols. And finally, social amplification of risks results in reactions that can shape pathways for risk assessment and management, frame views, fuel intergroup dynamics in response to risk, contribute to the accumulation of experiential knowledge and signals of different risk situations, and label and stigmatize some groups or outcomes as undesirable.
