FAQ-Frequently Asked Questions about a Polygraph

The Top Three Questions about Lie Detector Tests

Question #1:
He or she is very smart and I want to know if is it possible that they "fool" the machine or beat the polygraph?

Anyone can be fooled by someone's lie and facial mannerisms or other gestures that are not as reliable as a professional polygraph examination. Our personal impressions do not influence the electronic measurements at Texas Polygraph Counselors. We rely on advanced polygraph technology and training to interpret multiple high sensitivity signals and repeated clear questions. Attempts to conceal fail.

Decades of advancement in experimental controls and improvements provide a number of checks and balances that help us derive a professional opinion of truth or deception from multi-sensor charts. One of these sensors and repeats will reveal deception-faking. A few people try to manipulate the polygraph and there are a lot of goofy and incorrect ideas on the Internet, but we keep up with these amateur attempts that are caught by the modern computer polygraph and a well-trained licensed examiner. Those untrained attempts to fool the polygraph often result in nervousness and then backfire to confirm deception.

Question #2:
How much does a polygraph test cost?

Professional fees for a private issue or domestic infidelity examination administered by a reliable and licensed examiner is usually $350.00 to $500.00 in the Dallas area. Don't fall for a cheaper price without first meeting the examiner in person or taking a tour of the office and examination lab. A criminal case or someone facing criminal allegations or under investigation is usually $900.00 to $1,500.00 plus you must agree to pay for any court time or depositions if the examiner is subpoenaed later. Employee theft cases are usually $250.00 each times the number of people scheduled for an appointment.

Question #3:
How many questions may I ask?

Several questions can be asked but they must be of the same topic or issue being examined. A valid polygraph examination includes three or four types of questions as called for in the methodology but this is where your examiner can help during the pre-test interview. The interview homes in on and clarifies the most important issue into positive easy to understand fact-based questions. The questions are reviewed in advance to avoid any unfairness, uncertainty or surprise. A person with nothing to hide feels relieved and relaxed about questions that clear up the issue.

NO! Don't be fooled by these "toys"! In Texas only a state licensed polygraph examiner may legally examine someone for the purpose of verifying the truth of a particular statement. The so-called CVSA "machines" do not have any scientific support and no reputable federal agency relies on any of their claims. If someone offers you those as a substitute, that tells you their methods are not scientifically backed. It says they may be deceptive themselves.

What about accuracy and trying to fool the polygraph?

How accurate is a real polygraph examination?

Let's start with the understanding that while the polygraph technique is not infallible, research clearly indicates that when administered by a competent examiner, the polygraph test is the most accurate means available to determine truth and deception. U.S. Government studies have concluded that the single-issue test conducted properly by a qualified examiner is 87 to 95 percent accurate. Your national security organizations that quietly protect you every day rely at least in part on polygraphs regularly.
