Public anxiety about risks: Investigation of the structure and influential approach to them

全国性调查衡量了日本公众对各种危险的焦虑程度。采用分层两步随机抽样的方法，生成了具有代表性的日本公众样本。多元统计和随之而来的方差分析表明，人们最关心的危险因素是高负荷的“全球环境危机”因素，其次是“主要致死原因”危险因素。众所周知的灾难和事故并不引起人们的关注。结果还显示，当公众猜测每种危险的死亡人数时，他们对危险的担忧减少了。2011年东北地震后的调查结果显示，公众对核电站事故和地震以外的各种危险的担忧有所减少。2011年的大灾难让日本公众变得不那么谨慎。

Nationwide surveys measured the public’s anxiety toward a variety of hazards in Japan. A stratified, two-step random sampling method was used to generate representative samples of the Japanese public. A multivariate statistics and a consequent analysis of variance revealed that people were most concerned about hazards that highly loaded on a “global crises of environment” factor, followed by a “major cause of death” hazards. Well-known disasters and accidents were of low concern. The results also revealed that public’s concern about hazards reduced when they had guessed the number of deaths by each hazard. The results of the post-2011 Tohoku earthquake survey revealed a decrease in public anxiety about various hazards excepting nuclear plant accidents and earthquakes. The great disaster of 2011 made the Japanese public less cautious.
