The effects of mortality salience on perceived risk and trust in the managing bodies of nuclear power: The moderating effect of nuclear power support

Abstract

AbstractPublic concern regarding nuclear power has arisen due to accidents involving radiation leakages, natural disasters, terrorism, war and other incidents. That is, people's concerns regarding the use of nuclear power have grown as situations that threaten their survival have increased. This study uses terror management theory to examine how mortality salience affects people's risk perception and trust in the managing bodies of nuclear power. The results of Study 1 and Study 2 revealed that when the level of support for nuclear power is low, the effect of mortality salience increases trust in the managing bodies. Study 2's findings reveal mortality salience leads to decreased risk perception of nuclear power. In the case of risks that are managed by others and that are difficult to understand, such as nuclear power, people tend to place higher value on the managing bodies because they cannot handle the risk themselves. These results highlight the changes in people's perceptions of nuclear power managing bodies when they are conscious of death and provide important information on the nature of communication between citizens and experts regarding nuclear power.
