Have you ever been lied to by a potential candidate?


Have you ever been “lied’ to in an interview? Even just a small white lie?

“81% of people lie during an interview”, says Ron Friedman, award-winning social psychologist and the author of The Best Place to Work.

People are dishonest because it seems like it is the only way to actually get a job.

We are proud to announce that iFacts has recently added an exciting new addition to our range of services, namely the Voice Stress Analysis (VSA). We believe that companies can derive certain benefits from conducting VSA as part of their pre-employment process. Organisations are all too familiar with the more well-known methods for conducting pre-employment checks, including CV verification, interview processes, background checks, and a range of other tests. However, adding a VSA to your process can reveal a range of other results that might not typically be uncovered via these other methods.

Figures suggest that typically around 80% of people that are tested are actually ‘innocent’, and so it certainly makes sense to give these subjects as ‘friendly’ a test as possible. iFacts is of the belief that the VSA is a friendlier test, in comparison to the more widely known polygraph test, and this is why iFacts now offers this service.

What exactly is a VSA?

How would you feel about being made to take a ‘lie detection test’? Do you think you would pass or fail?

People typically know or have at least heard, of the analysis instrument called a polygraph. At a very general level, the polygraph is used to tell whether somebody is lying. However, the truth (excuse the pun) is that the Polygraph, and the VSA, is able to pick up much more subtle changes in behaviour or reactions in an individual, and this data can be used to make important decisions.

The mechanics of the VSA are fairly straightforward, at least in principle. The VSA measures the flexibility of a subject’s vocal chords. Typically, when a person is put under stress, they will enter into “fight, flight, or freeze” mode. This, in turn, causes their throat muscles to tighten, which has an effect on their vocal chords. Subjects are asked a range of questions by a qualified analyst, and the VSA measures the physical changes taking place in the subject’s body. However, unlike a polygraph, this is not done through any physical attachments.

Current trends indicate that people and organisations are actually moving away from the previously used polygraph test (the one made famous by movies), to the new Voice Stress Analysis. Opinions do differ in terms of which method is better, but the industry is certainly moving in the direction of the VSA. iFacts is proud to offer the VSA as part of our service offering, as we do believe that it can offer tangible benefits to particular (if not all) organisations.
