The science of Polygraph Testing is the subject of much conjecture and misunderstanding. Used properly, it can be a very valuable tool to any business, especially in South Africa where theft in the workplace is costing the economy Billions of Rands every year..
As an aid in investigations
(Specific issue Testing)
A lot of time, manpower and money can be saved through the use of the polygraph testing in investigating incidents in the workplace.
It can be used to identify deceptive parties, clear the innocent and clarify facts under dispute.
Pre-Employment

Information
- It is important to understand what polygraph testing entails. A polygraph instrument will collect physiological data from at least three systems in the human body. Convoluted rubber tubes that are placed over the examinee’s chest and abdominal area will record respiratory activity.
- Two small metal plates, attached to the fingers, will record sweat gland activity, and a blood pressure cuff, or similar device will record cardiovascular activity. A typical polygraph examination will include a period referred to as a pre-test, a chart collection phase and a test data analysis phase. In the pre-test, the polygraph examiner will complete required paperwork and talk with the examinee about the test.
- During this period, the examiner will discuss the questions to be asked and familiarize the examinee with the testing procedure. The examiner, when appropriate, will offer the examinee an opportunity to explain physiological responses in relation to one or more questions asked during the test.
- It is important to note that a polygraph does not include the analysis of physiology associated with the voice. Instruments that claim to record voice stress are not polygraphs and have not been shown to have scientific support.
