Abstract
This study examined the difference of information seeking behaviour depending on situations when people judge acceptance of a public project. It was confirmed by a questionnaire experiment. Waste dump construction was used as a theme, and local referendum and opinion survey by interview at street corner as the situations were used in the experiment. It was expected that internal information seeking preceded external information seeking, and people sought external information more in local referendum situation than in opinion survey situation. The results supported our expectation. It showed that people tended to behave differently in seeking information depending on their situation. Almost all participants answered that they sought internal information in both of the situations, however, they sought external information more in the local referendum situation than opinion survey situation. Furthermore, methods to provide a project's information from authorities based on the results are discussed.
