Lie Detector Test Machine
The Lie Detector Test Machine we use is commonly called a Polygraph, which stands for many writings, in the United Kingdom we know the Lie Detector Test Machine as a Lie Detector. The Lie Detector Machine was invented in the 1920s by John Larson and was an analog device, it continued to be improved and the computerized Lie Detector Machine were introduced in the 1992. Now all examiners will use a computerized machine to record the results more efficiently. Below is pictured a 1980s Analog device that Lie Detectors UK own but do not use. Its purely a prop in our offices.
A lot has changed in the industry due to the research that has gone into the techniques and validated methods that are used to polygraph someone today. Accuracy levels have risen greatly, now a single-issue lie detector test is 92% to 95% accurate. Most Governments now have polygraph programs, in the UK there are more Government employed examiners than there are private examiners. The UK Sex Offender Polygraph Program has put over 170 sex offenders who were on probation back behind bars it has been that successful.
There are four main brands of Lie Detector Test Machines available today and quite simply put they all do the same job, some excel in different areas. Lie Detectors UK use Stoelting CPS Pro polygraphs however Limestone, Lafayette and Axciton also make computerized Lie Detector Machines that are used by other qualified APA Examiners. Whilst it is not mandatory to use a computerized polygraph it’s something a consumer should be aware of and ask for, all qualified UK Examiners use the latest polygraph machines.
