What is a Lie Detector Test?

The “lie detector” is the common name given to the “polygraph examination”. These tests are ideal for peace of mind for any situation involving issues of honesty and integrity whether it be for individuals or the corporate and business sector E.g.
Relationships
Sexual abuse
Historical sexual allegations
ACC claims
Bullying
Sexual harassment
Sexual addictions
Porn addictions
Online activities
Corruption
Drug use
Steroid use & banned methods
Disclosure Statements
Commercial Investigations
Criminal/Civil investigations
and .......... more.

The polygraph test is based on key pertinent questions asked of a subject which only require a yes or no answer.  During a test the subject’s physiology is monitored and any movements in his/her cardio activity, electro dermal activity and breathing are recorded on a moving computerised chart. These charts and data are subsequently analysed to make a determination as to truthfulness or deception.

The time for the entire test process will vary and is dependent upon the complexity and number of issues to be addressed. Typically 2.5  to 3 hours can be expected for 3 series of tests.

A 3 Stage Test

Accused preparing for polygraph test
Pre-test interview 
A Consent & Indeminity  form are signed and general information is obtained from the subject. 

The polygraph process and equipment is explained to the examinee; all questions that are intended to be asked during the polygraph test are confirmed and reviewed with the examinee. 

There are no trick or surprise questions. No questions will be asked in a test that have not been discussed, fully reviewed and agreed upon with the examinee before hand.

The polygraph test 
At the commencement of this stage the examinee will have the polygraph components attached to their body on the outside of their clothing. 

These components include two pneumographs (to monitor cardio and thorasic breathing), cardio cuff (to monitor heart rate and blood pressure) and finger sensor cuffs (to monitor electro dermal activity). 

The actual main test follows an Acquaintance Test (warm up test) and contains the key question (issue to be addressed). The test is run a minimum of three times. The process is repeated for additional key questions.

A final analysis and result will be conducted subsequently and if necessary a  comprehensive written report will be prepared. 

Accuracy of the Tests

Over the last few decades, polygraph tests have proven to be one of the most powerful, robust and useful scientific tools and investigative aids in Relationships, Criminal and Civil investigations, Pre-Employment and Personnel screening and more....

Lie detector testing using the polygraph has been in use in the United States for almost one hundred years and is now widely used throughout the world. It is routinely used in almost all major investigations in advanced countries employing this forensic tool.
Whilst nothing is 100% accurate, the polygraph at 96% - ranks much higher than other investigative aids such as DNA, Police  Fingerprinting (28%), hand writing and witness evidence.

Note: The notion that the the Lie Detector and its evidence is inadmissible in New Zealand Criminal & Civil courts is totally incorrect. Only a Court Judge can decide as to its admissibility and this is considered on a case by case basis, primarily whether or not the evidence could be substantially helpful.
