Establishing the truth in a world where lies rule is a costly venture, as clearly demonstrated by the Cost of a Lie Detector Test. The test, also commonly known as a polygraph test, clocks an average of 80%-98% on its accuracy ratings.
Depending on the length of the exam, a polygraph test has a wide range of prices, from about 200 dollars to as high as 2000 dollars. A single session test lasting two hours will cost between 200-800 dollars. Different certified professional examiners will quote various low ends. A session can last for several hours a day, pushing the costs to over 2000 dollars. A home lie detector costs much less, starting from 90 dollars. However, its accuracy is not reliable.
The lie detector test should be administered by a validated specialist to guarantee reliable results, despite the exorbitant prices they charge.
