Polygraph Information

Why is a polygraph therapeutic and important?

A passed polygraph test result is an important way to help repair the broken trust in the relationship. It also promotes the healing that comes from a formal disclosure.

A polygraph holds the unfaithful partner more accountable to tell the entire truth… remember the twelve step slogan, “You are only as sick as your secrets”.

It may seem like the entire process is only for the betrayed partner, but it actually helps both the unfaithful partner and the coupleship to heal as well.

The Accuracy of Polygraphs:
While there are numerous myths about the accuracy of polygraphs and their permissibility, Dan Ribacoff explains that polygraphs are a proven and accurate science. Polygraphs have been experimented with and optimized over the past 100 years, since their initial conception in 1921. Dan Ribacoff, who is a certified member of the American Polygraph Association, claims that the most accurate form of polygraph examinations is 99.4% accurate, which is more accurate than most medical tests!

While on the subject of medical tests, Ribacoff also explains that polygraphs can be classified as a scientifically proven medical test, as it includes the use of medical instruments to test for physiological changes in a subject when making a past-event-based statement. While there may be skeptics and critics of polygraphs, you can’t argue with science. Especially with a science that has been globally tested and has even been tested and approved for accuracy by the United States Military.

Polygraph Fees
Fees for polygraph examinations vary widely depending on the situation and the type of testing involved. A typical polygraph exam conducted in one of our New York offices can range from $500+ plus taxes. 100% retainer fee is required for all clients, at the time of booking an exam. Please note that retainers are non-refundable and appointments are non-refundable and non-reschedulable. You are purchasing a time slot in our testing schedule.

"But too often, Ribacoff says, we want to believe the best about people, so we wind up suppressing that intuition. “We have human intuition built into us from caveman days—fight, flight, freeze, or surrender,” he says. “And people wind up killing that [intuition], and that’s how they become victims. They’ll actually turn their own radar systems off.”
So how can you tell if someone is being dishonest? Ribacoff says that there are physiological changes that happen in your body when you lie. The polygraph machine is an instrument that was created to measure these changes.

“The polygraph is actually several medical instruments that were put together to detect physiological changes that take place in the human body when a person lies,” Ribacoff says. “The truth is in your memory. Your memory is like the hard drive in your computer—record found, no record found,” he explains. “When you give me the truth, your brain is not working very hard, because it’s accessing information that is already there or not there. When you want to lie, your brain must work harder. You have to create the lie, usually by accessing information that is already in your brain, and mixing the two: lie and truth. And then you have to express the lie in a way that seems credible.”

Ribacoff says that magnetic resonance imaging (MRI) scans show that when someone tells the truth, they use only about seven parts of their brain. But when they lie, they have to use about 15 parts of their brain.

He compares the experience of watching a polygraph machine work to watching a mechanic check a car engine. “Your brain really goes into ‘rev the engine’ mode when you lie,” he says.

In fact, the human brain and a car motor are actually quite similar in what they need to operate. Just as an engine needs fuel, oxygen, and cooling to run properly, the brain needs blood, oxygen, and cooling. “When you lie, you call for more blood, your blood pressure increases, your heart rate [increases], your oxygenation of that blood has to increase,” Ribacoff says. “And your sweat glands have to activate, otherwise your brain will overheat.” These bodily changes, all medical in nature, are how the polygraph does its work. “You can’t feel it, you can’t control it. But we can measure it.” Obviously, you’re not going to be able to hook everyone you suspect of lying up to a polygraph machine. Even if you could, you wouldn’t want to. The process is tedious. A lot of preparation goes into a polygraph interview, and the test often has to be done three to five times. And although it’s not true that a polygraph machine can be “beat,” it is possible to deceive an inexperienced examiner.

There is no way to beat a polygraph instrument,” Ribacoff says. “[But] you can defeat the examiner.” The internet is full of misinformation on how to “beat” a polygraph. “Really, none of it works, because an experienced examiner will see that [the behavior is] not natural,” says Ribacoff, adding, “because there’s only one reason to try to beat a polygraph test: You’re lying!”"

The Utility of Polygraph in Sex Addiction Therapy
Polygraph testing is a valid and reliable way to discern truth from deception on a wide range of issues including in therapeutic settings. In the past polygraph and professionals working in psychology were at odds. However improved technology and better standards in polygraph have brought the two camps together. Now, polygraph plays a critical role in the risk assessments done by psychologists in post-conviction sex offender cases. Virtually every state now includes polygraph in their post-conviction release process for sex offenders.

In a 2003 report on polygraph by the National Academy of Sciences, the panel stated, “We conclude that specific incident polygraph tests can discriminate lying from truth telling at rates well above chance but below perfection.” Much of the criticism of polygraph, including the criticism by the NAS is focused on pre-employment screening tests, not specific incident testing such as sex addiction disclosure testing.

In a 2020 meta-analysis of polygraph research, Charles Honts, Professor of Psychology at Boise State University (2020) found polygraph accuracy rates to be 91.6%. Across dozens of studies, the ability of humans to determine truth or deception is 54%. This includes police, prosecutors, judges, and the general public. So, polygraph provides significant information gain to therapists.

In a study by Elliot, Egan, and Grubin (2017) titled the “Bogus Pipeline Effect,” the researchers found that participants in the study who faced the prospect of undergoing a polygraph examination provided dramatically more information (86% vs. 36%) compared to a control group where polygraph was not mentioned. So, therapists who use polygraph increase the amount of information they obtain simply by including the polygraph in their client discussions.

There is now very little debate in the scientific community that when properly administered polygraph can be of significant value to end users. Sex addiction therapists who use polygraph have by and large been very happy with the information produced. Therapists should be careful to only use examiners who are full members of the American Polygraph Association.
