Scientific Validity of Polygraph Testing: A Research Review and Evaluation--A Technical Memorandum [open pdf - 1MB]
From the Foreword: "This technical memorandum presents the results of the Office of Technology Assessment's (OTA) review and assessment of the scientific evidence on the validity of polygraph testing. Conducted at the request of Rep. Jack Brooks, Chairman, House Committee on Government Operations, and Rep. Frank Horton, the Ranking Minority Member, the OTA memorandum is intended to assist the committee in its deliberations on proposed changes in polygraph use by the Federal Government. [...] We first discuss the various types of polygraph testing procedures and ways in which the polygraph is used, and then summarize the judicial, legislative, and scientific controversy over polygraph testing validity. Next, we review and evaluate both prior reviews of the scientific research on polygraph validity and the individual research studies. Finally, we discuss the range of factors that may affect polygraph validity and the possibilities for future research, and present OTA'S conclusions about the scientific evidence for current and proposed Federal Government polygraph use."
