This study clarifies why information providers conceal risk information in a continual relationship with asymmetric information, even though it possibly causes damage to the provider in long-term interaction. In an experiment, participants were divided into pairs of "provider" and "receiver," and they interacted repeatedly. The results of the experiment were as follows, (1) Information asymmetry possibly elicited risk aversion in receivers, and the providers' expectation of the degree of this risk aversion influenced the behavior of the providers. (2) Concealing risk information generated benefit as long as the receivers did not detect it, but once they learned of it, they became more risk averse and decreased trust in the provider. The providers, however, did not change their behavior, continuing to conceal the risk information instead of becoming honest. These results suggest certain circumstances in which concealing risk information might benefit providers in the short term and could prevent damage caused by a receiver's risk-averse behavior in the long term.

It is important to infer and respect others' values and attitudes for fruitful communication. This paper examines how experts and lay people infer others' risk perception. According to the 2009 questionnaire survey for academic professionals and the general public, professionals estimate that there is a larger difference in risk perception of the technology that they study between themselves and lay people than the general public does. The professionals who hold this feeling perceive the risk of technology as being lower and estimate lay people' s risk perception to be higher. They also focus on positive more than negative aspects of the technology, evaluate its benefits, and tend to presume that negative media coverage greatly affects public perception.

A new method of detecting and controlling for acquiescence response biases in questionnaire studies was developed and applied to a cross-national survey data on trust collected by Yamagishi & Yamagishi (1994). Instead of including a set of balanced items or a large number of mutually unrelated questions as was common in conventional methods for assessing acquiesence, the proposed method uses multiple, mutually independent sets of items selected based on a principal component analysis. A relatively high correlation (r=.56) between two independent indices of acquiescence (obtained from two independent sets of items) suggests validity of the proposed method. No statistically significant differences in acquiescence were found between American and Japanese respondents suggesting that the results of Yamagishi & Yamagishi's results were not due to crossnational differences in acquiescence responses.

温暖化対策としての原子力の重要性が高まる中で, 信頼回復の切り札のひとつと考えられているのがリスクコミュニケーションの実施であるが, 原子力分野でこれを意図した活動が幅広く行なわれているとはいえない. 本稿では, 東海村を実験地として行われたリスクコミュニケーション活動の設計意図と実施内容を示すとともに, リスクコミュニケーションに対する住民と原子力事業者の評価を分析し, 原子力技術利用に伴うリスクに対する住民の視点を明らかにする. また, これらの住民の視点がどのように原子力施設の安全に関与するかを示し, リスクコミュニケーションにおける課題を論じる.
