In the summer of 1939, President Charles G. Haines set up this committee and instructed it to study broadly the contribution which political scientists are making to government, their relations with public officials, and how these relations might be made closer and more effective. The problem assigned to the committee is one of great importance to the future of political science. The challenge to political scientists to make an effective contribution to the improvement of government processes and institutions was never so real and so great as it is today. The preservation of democratic institutions, in the long run, will depend in large measure upon scientific study and research, and intelligent, imaginative, and constructive consideration of governmental problems. If political scientists are not making their full contribution to the development and improvement of government—and we believe they are not—it is time to stop and take stock, and to set about purposefully to attune political science to the needs of modern society. We are not unmindful of the very great contribution which all social sciences may make, but we believe that the responsibility of the political scientist is especially great.
