Assessment of Social Implications of Nanotechnologies

Application of Problem Structuring Method Based on Interview Surveys and Cognitive Maps

Abstract

　This paper aims at developing a problem structuring method based on interview surveys of key stakeholders and a visualizing technique, called “a cognitive map.”We found that this new method, based on interactive process with key stakeholders, was able to draw broader and more detailed issues than previously anticipated. We also found that the proposed method was useful for the analysis of societal implications of emerging technologies, such as nanotechnologies, which are not easily defined. It is confirmed that the proposed method can clarify common and diversified issues based on perception of key stakeholders, and identify additional stakeholders to be interviewed.
