ABSTRACT
The intelligence function adapts itself to changing conceptions of policy and to innovations in the procedures by which facts are gathered, analysed, and presented. New policy ideas are to-day resulting from the vast transformations that are taking place in the structure of society, state, and government. New methods of observing, analysing, and reporting data have arisen as an outcome of the growth of modern social and psychological sciences. So swift is the stream that we may fail in every effort to chart the banks within which it flows; yet the importance of seeking to understand the complex relationship of policy and intelligence is great enough to justify the risks involved.
