Why Use Qualified and Accredited Examiners?

There are currently very few laws and regulations in South Africa monitoring the implementation and use of polygraph examinations. The result is that there are a lot of unqualified and unaccredited individuals offering polygraph examinations which can have detrimental consequences for the persons being examined, the investigation and the company. To increase the concern, there are many tools and instruments being sold as 'lie detector tests' that simply has not been scientifically verified as valid and reliable means of detecting deception. Even worse, some of these tests are being advertised as 'polygraph examinations' or some variation thereof.

Using unqualified and unaccredited examiners or detection of deception instruments that has not been scientifically validated can have severe implications for the future of company employees, and can have detrimental financial implications for your company. These examinations are also rarely accepted as part of a bundle of evidence during independent hearings and arbitration. In essence, the company has a responsibility to all parties involved to ensure that the correct examinations are implemented.

Using qualified and accredited examiners that are members of professional organizations ensure that scientifically valid and reliable techniques are utilized according to the correct protocols. Members of professional organizations are also actively monitored to ensure good standards of practice and the ethical implementation of polygraph examinations. The organizations also provide continuous and advanced educational seminars, ensuring that their members stay up to date with the latest advancements in the field.
