Abstract |
福島第一原発事故を契機とする福島県産作物に対する「風評被害」は、事故発生後数年を経てもなお完全には消えていない。その背後には、放射能関連リスクにかんする人々の態度・認知・情報ソースの信頼性・感情反応などが、互いに強い相関関係を持ちつつ全体として否定的な方向に動くという、他リスク要因 (火事、病気、地震など) とは異なった特徴を持つためであることが示唆された。そうしたリスク認知の背後には、危険を見落とした際 (第二種の過誤) の損失を避けるバイアスが働いていること、そのために食品に関する批判的思考スタイルを持つことが、却って福島県産作物への買い控えにつながる可能性が示された。
Reputational damage towards Fukushima products (a.k.a. Fu-hyo-higai), persists in Japanese society despite several years since the nuclear power plant accident in March 2011. The current research proposed that such persistence is not a result of lack of scientific literacy in the society but a result of “rational” responses of people to minimize damages that will be incurred if one fails to detect radioactive contamination. In support of the proposal, we found that 1) negative attitudes, cognition, emotion, and perception towards radioactive related risk factors were highly interrelated with each other, and 2) individuals with higher media- and food-literacy were more likely to refrain from buying Fukushima products. We suggest that understandings of people’s rational error management psychology are required to prepare for highly probable future disasters in an earthquake hot zone with numbers of nuclear plants (i.e., Japan).
