Lie Detector Testing Cost


How Much Does Lie Detector Testing Cost?

 
low costHome Voice Stress Machine: $90 average costTwo-Hour Session with Polygraphist: $200-$800
post Post   Comments (25)  

Lie detector tests, also called polygraph tests, are used to determine whether a person is telling the truth. According to the American Polygraph Association, research has shown standard lie detector tests are 80%-98% accurate[1] . The accuracy of voice stress testing, however, is much lower, research has shown. Lie detector tests are used for a multitude of reasons including infidelity, immigration, theft, robbery, drug use, sex offender history and vandalism. The test usually measures physiological responses in blood pressure, pulse, respiration and skin conductivity.

Typical costs:

  • Lie detector tests conducted by certified professionals typically cost $200-$2,000. The length of the test plays a factor in the price, with all-day tests on the high end of the range. Typical two-hour, single-issue polygraph exams are generally $200-$800. For example, Holland Polygraph Services[2] , servicing western Washington state, starts tests at $400, but warns the price can go much higher. The Polygraph Examiner[3] , which operates in North Carolina, South Carolina and Georgia, claims most tests it administers cost $350-$600. Capitol Polygraph[4] , in Michigan, charges $325-$500 for most tests.
  • Home lie detectors are also available for about $90-$700, although the accuracy of home testing units and voice-based testers is not considered reliable. (The American Polygraph Association says research has shown about 65% accuracy[5] in voice-stress tests.) A voice-stress test called the De-FIB-ulator[6] sells for $89-$99. Older lie detector units are sold on eBay[7] , typically for about $700.

What should be included:
  • A single-issue polygraph test typically takes about two hours to complete. During the test, four to six sensors are attached to the test-taker's body. The test begins with a pre-test interview with control questions and is followed by the actual test and collection of physiological data. The test subject is likely to be asked to lie in order to elicit a physiological response as a part of the control questions. Most tests end with an analysis which is shared with the test taker.
  • Police Link, an online police community resource, posted an article on "Taking the Mystery out of the Polygraph Test"[8] that provides an overview of what to expect during an exam.
  • The Employee Polygraph Protection Act, a federal law established in 1988, set guidelines for private employers to conduct lie detector tests. The American Polygraph Association provides an overview of the law[9] . The Department of Labor has the full text[10] of the law.
  • Polygraphists are certified through the American Polygraph Association after completing an accredited training program. StateUniversity.com[11] describes a polygraphist's necessary training and education.
Discounts:
  • Some professional testing services offer discounts on multiple tests on the same issue. For example, C & C Polygraph[12] , with several offices in Idaho, offers unspecified discounts on multiple tests. C & C Polygraph also offers a 20% discount to return customers. Equalizer Polygraph, serving western Washington, has a "His and Her" special, with $50 off the total cost when two partners take an infidelity related polygraph test.
Shopping for lie detector testing:
  • The American Association of Police Polygraphists offers a searchable database[13] of lie detector testing professionals.
  • The American Polygraph Association has a searchable listing[14] of its members.
  • Contrary to a popular myth, polygraph tests are admissible in court. The Polygraph Examiner provides an outline of previous cases involving polygraph admissibility[15] .

Was with my boyfriend for 12 years. Was 100% faithful. But bc I was raped in 2013, he started to question my honesty and fidelity. After YEARS of abuse, criticism, fights and nervous breakdowns, I decided to spend the money and have one done.. Not just to prove myself to him once and for all but TO PROVE TO THE WORLD THAT I WAS INFACT, THE HONEST, REAL, TRUTHFUL WOMAN I CLAIMED TO BE! I take pride in being that girl & you cant put a price tag on PEACE & PRIDE.
Needless to say I passed with flying colors.. waiting on him to muster up the guts to go and have one done! Probably not going to happen.. IDC.

I was saddened when I saw how much a test would cost. My daughters are in the midst of a very sad war. My oldest daughter has been accused of stealing $300.00 from my youngest 13 year difference). My oldest is a clepto by defined by the dictionary. She promises she is innocent and they hate one another. She said she would take a test and I am disabled, (they don't work), if you know SSec. you know they are not the best payers. I hope something stops this, it is tearing this family apart!
