The perception of technological risks: A literature review

Abstract

In response to rising concern about technological risks, a concerted effort is being made to improve risk analysis methods and risk management approaches. As part of this effort, behavioral and social scientists have produced a substantial body of knowledge of value to risk analysts and decision makers. This paper focuses on behavioral and social science studies of human intellectual limitations in thinking about the risks, factors influencing risk attitudes and perceptions, and factors contributing to social conflicts and disputes about technological activities. A basic assumption of the paper is that analysts and decision makers can benefit from a better understanding of how experts and nonexperts think and make decisions about technological risks. Without such understanding, well-intended policies may be ineffective or even counterproductive.
