초록

Objective : The objective of this study was to examine how experts and the public perceived various environmental
and technological hazards based on psychometric paradigm.
Methods : We conducted a survey that included 30 hazards and 10 risk attributes. Subjects of this study were 214 people
with three groups; (1) experts (55 people), (2) graduates( 78 people), (3) under graduates (81 people). Factor analysis
was used to confirm the common risk attribute from 8 risk attributes. Also, multiple regression analysis was used to
identify factors influencing on perceived risk and benefit of hazards.
Results : This study revealed that experts tend to be more tolerant than graduates and under graduate students for the
30 hazards. Using factor analysis, two main factors were identified: factor 1, commonly called “Dread Risk”, and factors
2, commonly called, “Unknown Risk” in the literature. We identified that environmental hormone concentration and
global warming ranked high in both dread risk and unknown risk. Multiple regression models were used to test the association
of perceived social risk and perceived social benefit with two main factors. Dread risk had significant explanatory
power on perceived social risk and benefit. We identified that the experts were less likely to perceived dread risk
and know more information about the hazards.
Conclusions : There were differences of risk perception between experts and lay people. Especially, experts' perception
of risk was commonly lower than other people's perception.
