Eye-Detect

After Dektor invented the PSE system for lie detection in 1969, soon various people started to create and sell their various gadgets and ideas for lie detection. Gadgets used red or green blinking lights,  numbers, meters, etc. to indicate “lies” by people. Some sellers have tried to claim their gadgets were “voice lie detectors”, the same as the PSE system because their device or software program reacted to vocal sounds. That is NOT Voice Stress Analysis®. Only Dektor created the technology of Voice Stress Analysis in 1969. With the invention of the portable laptop computer in about 1980, some people are selling software programs, using various software gimmicks, to make people think their programs were doing lie detection. They are still selling them to both the private sector and law enforcement with disastrous results to the buyers because of their very poor accuracy and they usually do not offer any training at all. Some of the more elaborate “lie detectors” tried to claim brain “mermers”, facial muscle changes, body language, etc. could be used for lie detection. Today, there are still only two proven systems for lie detection: PSE and computer polygraph. The polygraph system has many limitations, drawbacks and inconclusives. There are many counter-measures that will alter the results of a polygraph test that cannot be detected by the polygraph examiner. The PSE system does NOT have any of those polygraph problems.

About 2015, another type of gadget started to be sold for lie detection called Eye-Detect. It is sold by a company in Utah called Converus. It uses a special camera, connected to a desktop computer, to record the movements of the eyes while the test subject vocally answers various questions on a computer screen about a crime or for employment screening. At the end of the test, the device gives the results based on a mathematical formula the sellers claim they have invented.

As of May, 2018, Eye-Detect is being pushed by former polygraph examiners. It was sold by the Lafayette polygraph business for a short while, but has since stopped selling it. Converus website is very fancy, with a lot of flash type graphics. It gives very little in useful information. A person must call to find out the important information, such as price, how it works, etc.

There are many problems with this device and Converus selling and promoting it. About ten years ago, the polygraph business created a hand held gadget called Pcass. The polygraph business was pushing it only because it was a polygraph type device. Its so-called “accuracy” was being pushed by various high level polygraph people. Pcass was a polygraph type device with one wire attached to a person for the test. After the very short “lie test” was given, the “answer” would appear as green, yellow or red. Green meant truth and red meant lie. It cost the U.S. tax payers about $3 million to develop. It was for U.S. military in Iraq to test civilians to see if they were terrorists. The military bought 100 of these gadgets at $7,500 each. The problem was there were no independent studies done to determine its accuracy BEFORE Pcass was bought and used by the military. It was later proven the accuracy was no better than a coin toss.

Although Converus says on its website it has many scientists, highly educated advisors and several high level polygraph examiners, the final product and its lack of any real lie detection training are NOT able to determine completely accurate and reliable truth or deception, especially when it is compared to the PSE system. It is clearly just another lie detection gimmick sold to make the sellers money. Converus calls the buyers of Eye-Detect “partners”. Walmart calls their employees “associates”.

Lie detection is NOT something that can be learned easily by having only a extremely short (two hour) on-line only course on how to use Eye-Detect and perform a lie detection test. That is only what Converus gives to “train” examiners. At the end of that so-called “training”, a person is given two, fifty question tests as the final exam. If the two tests are passed, he is “certified’ as a Eye-Detect examiner. Untrained examiners (those that have not taken a complete Dektor or polygraph course) would not know how to talk to a suspect about an incident, how to obtain confessions or how to interview or interrogate a suspect about an incident and how to properly compose questions.

There are many, many other problems with Eye-Detect. There is never any recording of the pre or post test interviews, if any are ever used by the examiner. This leaves open the probability of lost confessions that can be used in court as evidence or lawsuits against the Eye-Detect examiner because of untrue accusations by the person taking the test, such as accusing the Eye-Detect examiner of making racist remarks to the suspect, unkept promises made by the Eye-Detect examiner, claims of sexual demands by the Eye-Detect examiner, etc. Major disasters waiting to happen to any Eye-Detect examiner. According to their website, drugs or alcohol will affect the results. No tests are given to ever determine if drugs or alcohol are present before a Eye-Detect test so any test results cannot be relied upon. Eye makeup or movement will throw off the tests which may not be seen by the Eye-Detect examiner. A person must have average reading ability or else the test cannot be given. A blind person cannot take the Eye-Detect test because he cannot read the test questions. Fatigue will also affect test results. Any condition that affects the autonomic nervous system will affect Eye-Detect test results.

The employment screening test has 300 questions and a specific test has 100 questions. Each test takes about 35 minutes. While taking the test, the person must rest his chin on a hard, plastic stand. This causes much discomfort because each test takes about 35 minutes. The person must sit absolutely rigid for that time. If a person is in any type of pain, he will not be able to concentrate on the questions and that would cause a false answer. Those same problems also exists in every computer polygraph/polygraph test. On their website, the sellers of Eye-Detect say their test is a good start before a polygraph test is given. If their gadget is not accurate enough for lie detection, why should anyone buy it and waste their money? The PSE test only takes about two minutes and the person sits in a comfortable chair and can move around without causing any problems with the test results.

The cost of Eye-Detect is $3,800. The Eye-Detect equipment is not portable. The complete PSE system is totally portable in a lightweight laptop. The owner of a Eye-Detect must pay $100 to Converus for EVERY test they give to one of their employees or $50 for EVERY test they give to a person not in their company, for LIFE!! The fact is, the owner of a Eye-Detect device will never own his device, he is only leasing it. When a person buys the PSE, he owns it. He never has to pay any extra fees, such as “recertification fees” per examiner, per year for life that imitation “voice lie detectors” charge.  The PSE is a far superior system to buy and use for lie detection.

When all the factors are considered, the PSE still proves it is the “Easy to Learn, Easy to Use” lie detection system and still superior over all other gadgets and devices for lie detection.
