Questions we can answer!
Q: What is a lie detector test or polygraph?
A: “Poly” means many and “Graph” means writing. We monitor five parameters (many) of a persons physiology. The polygraph is not a machine. It is a scientific instrument that measures involuntary responses of electrodermal activity, heart rate, blood volume, and thoracic and abdominal breathing.
Q: How many questions are allowed?
A: We limit the number of questions you can ask to no more than 5. The reason for this is the latency effect. We do not want the person being tested to keep saying no or yes too many times. Such responses could easily skew the results
Q: How do I beat a lie detector test or polygraph test?
A: Don’t show up for the polygraph exam. The testing method we use is 97% accurate and 3% inconclusive (meaning that we cannot determine truth or deception).
There are many different opinions regarding whether or not it is possible to beat the polygraph. Some people who have failed the polygraph test have written articles discrediting the polygraph, stating that it is possible to beat the polygraph. These people, who do not fully understand how the polygraph works, try to advise others how to successfully beat it through the use of counteractive measures such as alcohol, medical drugs or self hypnosis.
Today, all existing countermeasures are well known to polygraph examiners. There are many ways to identify the attempts of using countermeasures during a polygraph test. In other words, a person who tries to use countermeasures during a polygraph test (or tries to beat the polygraph) will be readily identified by the examiner. It is always necessary to remember that a person who has nothing to hide will not try to use any countermeasures or any other actions to beat the polygraph during the examination.
