Abstract
CIE (the Civil Information and Education Section of GHQ/SCAP) made Japan acquainted with public opinion surveys during the occupation period (1945-1952). Until now, there has never been an analysis which clarifies how the social environment was investigated by CIE when public opinion surveys were first introduced and applied in Japan. The purpose of this paper is to show how CIE and Japanese researchers analyzed the undemocratic social environment that made public opinion surveys difficult. I will show this by investigating the material of Herbert Hyman. It was vital for Hyman’s analysis to acquire information from Japanese social scientists and the members of survey associations. As a result, CIE had to conduct public opinion surveys in cooperation with Japanese scientists and members of survey associations. Through their endeavors to inform Hyman of the social environment, Japanese scientists and agents clarified the relation between Japanese attitudes and the undemocratic social environment in Japan.
