Polygraph Testing FAQs
Whose side is the polygraph examiner on?
The polygraph examiner serves as an independent and neutral party, ensuring that the lie detection process is fair and accurate. Their primary responsibility is to conduct the polygraph test and accurately report the polygraph test results, which is crucial when preparing for a polygraph test.
What question(s) will be on the lie detector test?
The client and the polygraph examiner collaborate to develop test questions tailored to the client's specific concerns or issues. These questions can be crafted for a single issue or multiple issues of interest. Additionally, some questions are designated as control questions, which are standard inquiries used in every test. Preparing for a polygraph test involves understanding that the results will assist in determining a person's past actions or conduct, making lie detection a critical component of the process.
What are the possible polygraph test results or outcomes?
The following are the possible polygraph test results, which play a crucial role in lie detection:
- No Deception Indicated (NDI): This outcome means the person has passed the polygraph test.
- Deception Indicated (DI): This result indicates that the person has failed the polygraph test.
- Inconclusive (INC): In this case, the person has neither passed nor failed the polygraph test. If this outcome occurs, up to two additional attempts can be made to achieve an NDI or DI result.
- No Opinion (NO): This means that there was not enough data or information collected from the individual being tested to yield an NDI, DI, or INC result. (Note: for a NO result, the client will be responsible for the full cost of the polygraph test. If requested, another test can be rescheduled at full cost.)
When preparing for a polygraph test, it's essential to understand these potential outcomes.
What is the cost of a polygraph tests?
The cost of a polygraph exam can vary based on the complexity and type of the polygraph test being conducted, as well as the location (town, city, state, or country; see 'Services' for starting price). Factors such as lie detection methods and polygraph test results also influence the pricing.
To schedule a test, a non-refundable deposit of $300.00 is required, which will be applied to the total cost.
If you need to reschedule your polygraph test within 2 days of the scheduled date, an additional deposit of $300.00 may be necessary, which again will contribute towards the total cost of your polygraph test. Additionally, taking the time to prepare for a polygraph test can help ensure accurate results.
How long does a polygraph test take?
The length of time required for a polygraph test, which is crucial for accurate lie detection, can vary significantly. Most tests are completed in less than two hours, while others may take up to four hours. To ensure a smooth experience, it's advisable to allow extra time when preparing for a polygraph test. A good rule of thumb is to block out four hours.
What happens during a polygraph test?
The examination begins with a general introduction and overview of the reason for the lie detection test. You will need to sign one or two forms before proceeding to a detailed pretest interview. Next comes the actual polygraph test, which involves the collection of data and charts. Following this, there will be an analysis of the polygraph test results, and a post-polygraph test interview. During this final interview, an oral advisement of the polygraph test results will be provided, ensuring you are fully informed about your experience and outcomes while preparing for a polygraph test.
Will I received an official report of the polygraph test result?
A written report of the lie detection test results will be emailed to the client (the person paying for the test) within 72 hours. The examinee (the person polygraph tested) is entitled to request the report as well. This written report will be available only after a quality control (QC) review of the polygraph test charts is completed by an independent certified QC polygraph examiner, ensuring the accuracy of the results and proper procedures in preparing for a polygraph test.
How do I prepare to take a polygraph/lie detector test?
It's crucial to arrive at least 15 minutes early when preparing for a polygraph test. Wear comfortable clothing during the examination, and ensure you eat your usual breakfast or lunch. If having coffee or caffeine is part of your routine, that's fine. Don't forget to take your daily prescription or allergy medications; vitamins won't impact your lie detection results. Refrain from consuming alcohol or recreational drugs for 24 hours before the test. Aim to get a good night's rest before your appointment. Clear your schedule for at least 4 hours from the time your polygraph test is scheduled. Remember to bring your valid driver’s license or another form of government identification. Using the bathroom just before the polygraph test can help avoid unnecessary disruptions. It's important to note that no cellular phones or weapons are allowed during your appointment, and you should not bring friends, relatives, or children. Hydrate properly by drinking at least 32 ounces of water daily for at least 2 days leading up to the test. If you are pregnant, injured, or ill (e.g., with a cold or flu), please call in advance for specific guidance, as pregnant women will need a doctor's note. Additionally, refrain from researching 'how to pass a lie detector test', as this could adversely affect your polygraph test results.
