Lie detection or polygraphy test is one of the scientific methods in crime detection. Guilt complex questions have been used in many of the contemporary formats at one time or another in an attempt to identify those examinees who would produce a false positive outcome because of this tendency. The need for polygraph testing is felt particularly in industries which have high risk of theft and fraud (e. g., commercial banks), high turnover (supermarkets, other retail operations), or both. papers to the doorkeeper and then signed
