How accurate is a polygraph?

​

U.S. Government studies have concluded that when a qualified examiner conducts the test properly, the polygraph exam is between 88 and 91 percent accurate.

​

What type of questions can be asked?​

​

Test questions must be limited to “yes” or “no” and "true" or false" answers. The test questions must have definite objective answers and may not be opinions. The test questions must relate to past events of a factual nature.

​

How many questions can be asked?​

​

An examiner can usually cover one (1) to three (3) relevant questions during an exam. The more questions, the more the test will cost. Also, this assumes these questions are related to one another (see the question above). It takes about 60 minutes to cover these three questions effectively.

 

If it is necessary to ask more questions, another exam must be designed and conducted. This will add to the time and cost involved. Test results are usually less reliable with an increase in the number of relevant test questions. A healthy individual can only produce readable polygraph charts for a limited period of time; after this time has passed it is impossible to generate a conclusive polygraph test.

How Much Is A Polygraph​

​

We provide a wide range of polygraph pricing options to cater to different needs. Our polygraph exams are available in the price range of $300 to $400 per test, with three distinct packages to choose from.

 

OPTION One 1. "Examiner's Choice" Basic Infidelity: Price $300

This package includes a polygraph exam with one assigned question.

The assigned question cannot be substituted, but it can be adjusted to include specific names, dates, and times.
The question used in this package is as follows:

 

"Have you had any sexual contact with anyone other than your [insert relationship name, e.g., wife, husband, boyfriend, fiancé] since [insert marriage date, specific date, or start of the relationship]?"

 

This question can also be customized to include a specific person's name.

​

"Have you had any sexual contact with [insert suspected persons name ]"

or

"Have you had any sexual contact with [insert specific suspected persons name] since [insert date]?"

OPTION TWO. 2 Question Test: Price $350

​

Our second package is the "Two Question Test." Priced at $350, this package allows you to select three specific questions for your polygraph exam. However, please note that the chosen question will need to be reviewed and approved by our polygraph administrator before the test can proceed.

 

With this package, you have the flexibility to focus on a particular area of concern or interest. Our expert polygraph administrator will ensure that the chosen question aligns with the standards and guidelines of polygraph testing.

​

Please note that we offer additional packages with varying features and pricing options to meet your specific requirements.

​

OPTION THREE. 3 Question Test: Price $400

​

Our second package is the "Two Question Test." Priced at $400, this package allows you to select three specific questions for your polygraph exam. However, please note that the chosen question will need to be reviewed and approved by our polygraph administrator before the test can proceed.

 

What does the test consist of?​

​

The polygraph examiner receives and reviews the facts of the case. The examiner formulates the specific test questions based upon the facts of the situations and the examinee’s version of the events.

​

The examiner explains the test process to the examinee and reviews the facts of the case during the pretest interview. At this time the examiner reads each question to the examinee to make sure each one is easily understood.

​

The examinee is attached to the polygraph instrument and given additional instructions. 

 

The questions are read by the examinee while they are attached to the polygraph instrument using sensors that measure eyes, heart rate, breathing, seat pad and sweat gland activity. These measurements are charted on graphs or stored in the memory of computerized polygraph units.

​

Upon completion of the questions, the computer will analyze the charts and numerically score the charts to make sure that his analysis is within the acceptable limits of the instrument. This score results in a conclusion that the examinee has answered either truth, deception or is determined to be inconclusive.

​

The examiner will transmit the test results to the client via email with a polygraph report by the end of the business day. 

 

NOTE: Polygraph exams are conducted in private. No other persons are allowed in the examination room during the test. Most reputable examiners videotape the examination for the protection of all parties involved.

 

Prior to the polygraph exam, clients are required to abstain from consuming any drugs or alcohol. It is strictly prohibited to employ any countermeasures during the test. Additionally, clients who wear eyeglasses are advised to bring them to the examination. However, if you have eyelash extensions, or any contact lenses used to alter the pupils, they must be removed before the test.

How Does The Polygraph Detect Lies From The Eyes?

​

The EyeDetect technology is a computer-based deception detection system that uses eye behavior combined with a standard computerized polygraph instrument o assess truthfulness. It does not directly involve the eyes themselves but rather measures various eye-related parameters to infer deception or truthfulness.

 

EyeDetect utilizes an infrared eye-tracking camera to monitor and analyze specific eye behaviors during a test. These behaviors include pupil dilation, blink rate, fixations, and saccades (rapid eye movements). The system tracks these eye movements and combines them with other physiological responses such as changes in skin conductance and respiration patterns.

 

The underlying principle is that deceptive individuals may exhibit distinct physiological responses, including changes in eye behavior, when they are lying or being deceptive. The EyeDetect software compares the eye-related measurements and other physiological responses against established baselines and algorithms to determine the likelihood of deception.

​

EyeDetect works with our polygraph instrument, providing our clients with TWO polygraph exams all in one. The EyeDetect primarily relies on analyzing eye behavior, including pupil dilation, blink rate, fixations, and saccades, along with other physiological responses such as changes in skin conductance and respiration patterns.

 

But, unlike the old polygraph equipment where the examiner determines if your telling the truth or not, this test is administered and scored by algorithm — not an examiner — so it has perfect reliability!
