Polygraph Testing & Lie Detection

Trusting people is not always possible if the person is untrustworthy. Sometimes you need help to find the truth and help to get peace of mind. Lie detection via polygraph testing is the process of using technology to monitor and record the various manifestations of the sympathetic and parasympathetic nervous systems through prudently designed questions asked of the individual who is attached to the polygraph.

The manifestations of the Sympathetic and Parasympathetic Nervous Systems are comprised of deviations in blood pressure, pulse rate, electrodermal activity, and respiration. A polygraph or lie detector is a diagnostic instrument that is used by a professionally trained and experienced polygraph examiner who administers the examination in order to verify the truthfulness of a person’s claim regarding a precise issue.

Many people believe that polygraphs are inaccurate and create more problems than they solve. This is a very normal concern; however, it is essential to know that in a specific issue test, while using a validated technique, the average accuracy of a polygraph will exceed 90%.

Our professionals use voice stress analysis along with polygraph testing to determine truth. Voice stress analysis can be used in a variety of ways: in person, via recorded message, telephone, radio communications, and even archived recorded material.

Voice stress analysis is useful in the selection of qualified candidates in which stress and emotional reaction are a priority, or for professionals who have to perform critical negotiations or interpersonal assessment.

Voice stress analysis and lie detector tests can be used to measure the voice stress of competitors during meetings, corporate theft and fraud, infidelity, business negotiations, insurance claim verification, and much more.

I initially hired New York Intelligence to conduct background searches for my business when I was starting a new division. He finished all 12 reviews right on schedule! And then my Cousin Bucky went missing…well, David Schassler left his own birthday party to start tracking Bucky and he found him before my Aunt Louise even had time to worry! My family and I can’t say enough good things about Mr. Schassler and his firm. Hire them – you won’t be disappointed!
