The Augmented Human Intellect (AHI) system is a computer-based system designed to store, structure, and retrieve textual information in a way congruent with the characteristics of the individual. It provides for the hierarchical ordering of information and for the manipulation of text through a system of cross-referencing, modification, and selective retrieval. The AHI system was tested to see if its use affected the behavior of individuals, groups, and organizations. The system was implemented in a government research laboratory where job task types included an assortment of information and management positions. Direct observations, interviews, and attitude surveys were used to assess the effect of the system. The text provides a description of the system, the study design and implementation, and the results; the appendixes include tabular data relating to sampling, questionnaire findings, and other results.
