Abstract

Experts have been claimed to perceive risks in a different way than the general public. It is likely that experts often see risks in their own field of expertise as smaller than the public does, but that does not imply that their risk perception is also driven by other factors. Topical experts and general risk assessors are two quite different types of experts. Still, common assertions as to the simple structure of expert risk perception, said to be related only to technical or statistical risk estimates, builds on a meager database consisting of 15 general risk assessors. Results from a study reported here show that the factors explaining experts’ risk perception are similar to those of a comparable group of nontopical experts with a similar level of technological literacy and to the general public, and that the level of explained variance is quite comparable for experts and the general public.
