Frequently Asked Questions:

How Reliable and Valid is Polygraph Testing?
    The American Polygraph Association has a compendium of research
    studies available on the validity and reliability of polygraph testing.
    The 80 research projects listed, published since 1980, involved
    6,380 polygraph examinations or sets of charts from examinations.
    Researchers conducted 12 studies of the validity of field
    examinations, following 2, 174 field examinations, providing an
    average accuracy of 98%. A valid examination requires a combination
    of a properly trained examiner, a polygraph instrument that records
    as a minimum cardiovascular, respiratory, and electrodermal activity,
    and the proper administration of an accepted testing procedure and
    scoring system.
