Abstract
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.
