Introduction
Lie Detection Services
Valid scientific process or airy fairy speculation?
An uncomfortable situation develops in business when there is reason to suspect that one or more employees have been stealing from the business – in the form of products or assets; or intellectual property and business secrets being sold to, or shared with competition firms; or company benefits and/or assets have been abused, leading to loss of profit and the escalation of costs; employees being influenced to strike by trouble makers; etc.
What makes this problem sensitive, is the fact that you do not want to confront your employee(s) with unproven accusations, destroying the trust between you, unless you have valid proof supporting your accusation. Whatever method you use to get to the truth must therefore not create the impression that guilt is already assumed, but rather that you are following a due diligence process for truth verification – in the process also exonerating innocent employees from suspicion of involvement in any wrong-doing.
Using Lie Detecting services readily comes to mind – but can Voice Stress Analysis or Polygraph Examinations REALLY provide valid, scientific answers? And can they REALLY be conducted without alienating the examinee subjected to the test?
We propose that it is all possible - while these tests can be used to professionally determine the best avenue of investigation of possible deviant behaviour by verifying the truth spoken by the subject, their effectiveness lies primarily in the choice of service provider – their reputation for accuracy, reliability and validity; the equipment used, as well as the qualifications and experience of the examiners conducting the tests.
Welcome to the National Voice Stress & Polygraph Network
Because we realise the sensitivity of Lie Detecting, we build a trust relationship with our clients, putting them at ease that our examiners will conduct themselves in an ethical and professional manner, allaying negative perceptions employees may develop resulting from these examinations.
Our Network uses the best accredited equipment available globally, while all our examiners are highly qualified, experienced, and ethical. Being based in all the main centres of South Africa, we provide impeccable professionalism country wide, and in record time.
Any website enquiry is answered within 24 hours. (Examiners’ diaries may require 3-5 working days' notice, so please make your appointment without delay once you have decided).
