How reliable is a Polygraph test?

The polygraph is highly reliable, providing the examiner is properly trained and using the latest validated techniques and computerized equipment. The American Polygraph Association (APA) has gathered over 200 studies on the subject. Based on twelve separate studies involving 2174 actual cases since 1980, evidence suggests that qualified polygraph examiners are 98% accurate in their overall decisions. The use of the polygraph has evolved over the last ten years; techniques are now backed by science and accuracy with the latest computerized equipment.
