Polygraph Examinations

 

A polygraph examination or lie detector test measures changes in physical signs that are caused when a person answers a direct question untruthfully.  

Certified polygraph examiners conduct tests to determine the truthfulness of answers given to questions regarding drug use, marital fidelity, criminal activity and a variety of other subjects.  Polygraph examinations are used to verify the winners of many major fishing tournaments.  The Employee Polygraph Protection Act of 1988 allows examinations to be used as a pre-employment screening tool in some occupations.
