The polygraph technique is a useful investigative tool. It should not be a substitute for other types of investigations. Its use should be controlled with the utmost care, compassion, and sensitivity. Examiners should resist pressure to use the polygraph technique prematurely. Instead, investigators should work within the framework of a written policy that begins with conducting an investigation. Use of the polygraph is appropriate if inconsistencies or conflicts between different types of information emerge. The examinee may be someone suspected of making a false complaint to the police or falsely swearing to testimony, but technically the examinee is a victim until proven to the contrary. Sexual assault victims usually cooperate fully when they understand why they are being asked to undergo a polygraph examination. Criteria to include in a written policy include offering the suspect or accused a polygraph examination before testing the victim and avoiding polygraph examinations of sexual assault victims in the absence of any conflicting information.
