I saw an article on ITN which set out to explain how difficult it was to cheat a polygraph or lie detector test.Apparently it is almost impossible to hide your sweaty brow and twitching sphincter when you're asked if you exaggerated your insurance claim, slept with your secretary or murdered your wife and buried her in a landfill. I had a look around an found www.polygraphs.co.uk , the website of a company called Distress Services, who offer their expertise thus:
"From cheating husbands and wives to accusations of sexual abuse, Company theft to pre employment screening, Distress Services can offer advice and unique expertise in all aspects of the polygraph and lie detection. All enquiries are treated in confidence."
I have heard that although polygraphs are difficult to cheat they are far from an infallible method of telling if someone is lying. I would have thought that a system which relies on nervous reaction would not be able to filter out entirely the person's nervousness in being in an interview situation in the first place. It does however seem to be an increasingly high profile and presumably lucrative business as Distress Services site further explains:
"Bruce Burgess – Is employed to conduct polygraph tests for ITV's "Jeremy Kyle Show" and the UK production of the "Jerry Springer show".
As well as the above both Bruce and Guy have appeared on a number of other television productions. Distress Services offer unique expertise and experience to individuals and organisations across the UK, Ireland and Europe."
Jeremy Kyle? Jerry Springer? – It MUST be kosher!
There's a link to the ITN article (which centres around a company offering their employees the opportunity to try a polygraph in their lunch hour!)
