ABSTRACT
A prominent view of risk communication is through the lens of risk information; that is, as a process during which people exchange information about risk. 1 These exchanges typically involve the transfer of information about risks—risk messages—from experts to non-experts, and back again. The content of these risk messages generally takes the form of: (1) facts or hypotheses about the level of risk that exists within a system; (2) the significance or meaning of the risk relative to other issues of concern; or (3) decisions, actions, or policies that may be undertaken to manage or control it (NRC 1989).
