A Brief History of Basic Intelligence and The World Factbook
The Intelligence Cycle is the process by which information is acquired, converted into intelligence, and made available to policymakers. Information is raw data from any source, data that may be fragmentary, contradictory, unreliable, ambiguous, deceptive, or wrong. Intelligence is information that has been collected, integrated, evaluated, analyzed, and interpreted. Finished intelligence is the final product of the Intelligence Cycle ready to be delivered to the policymaker.
The three types of finished intelligence are: basic, current, and estimative. Basic intelligence provides the fundamental and factual reference material on a country or issue. Current intelligence reports on new developments. Estimative intelligence judges probable outcomes. The three are mutually supportive: basic intelligence is the foundation on which the other two are constructed; current intelligence continually updates the inventory of knowledge; and estimative intelligence revises overall interpretations of country and issue prospects for guidance of basic and current intelligence. The World Factbook, The President's Daily Brief, and the National Intelligence Estimates are examples of the three types of finished intelligence.
The United States has carried on foreign intelligence activities since the days of George Washington, but only since World War II have they been coordinated on a governmentwide basis. Three programs have highlighted the development of coordinated basic intelligence since that time: (1) the Joint Army Navy Intelligence Studies (JANIS), (2) the National Intelligence Survey (NIS), and (3) The World Factbook.
