摘要

In a set of experiments, information is presented to individuals on the likelihood of serious accidents from a chemical facility. Comparisons are made with other risks, such as fatalities from automobile accidents, to see whether laypersons can determine the relative safety of different plants. The conclusion is that a fairly rich context information must be available for people to be able to judge differences between low probabilities. In particular, it appears that one needs to present comparison scenarios that are located on the probability scale to evoke people's own feeling of risk. The concept of evaluability recently introduced in (Ref. 1) provides a useful explanation of these findings. (15 refs.)
