This new full-length book from the CIA's center for the Study of Intelligence is an attempt to translate and make available to intelligence analysts selected cognitive psychology technical reports on the processing of incomplete and ambiguous information. Compiled by Richards J. Heuer, Jr., the volume "pulls together and republishes, with some editing, updating, and additions, articles written during 1978-86 for internal use within the CIA Directorate of Intelligence." Users can read the full text of the report by section and chapter in HTML format.
