The absence of probable-lie comparison questions in an EyeDetect test eliminates concerns about any overlap that might occur between “relevant” and “comparison” questions (see “How is the polygraph typically used? What is the average accuracy for those uses?” above). The reactions to two sets of “relevant” questions are compared and each relevant issue serves as a control for the other issue.
An EyeDetect exam is almost completely automated and is administered by a computer. Therefore, the validity of the test does not depend on the interview skills of the examiner or their ability to properly interpret the physiological recordings. In contrast to a polygraph, the examinee for the EyeDetect exam does not attempt to appear truthful to an examiner.
EyeDetect tests can be developed for any language, allowing testing in the native tongue of an examinee. This eliminates the need for a translator and prevents language misunderstandings.
An EyeDetect test is less invasive than a polygraph test. During a polygraph, a variety of sensors are attached and some may cause discomfort. For EyeDetect, because a remote eye tracker records eye behavior during the test, there are no sensors attached to the examinee.
An EyeDetect tests takes about 40 minutes, in contrast to a polygraph examination, which may take 2-4 hours. An organization can conduct up to six EyeDetect tests in the time it takes to conduct one polygraph test.
Note: EyeDetect has a limitation that is not an issue for polygraph tests ― the examinee must have proficient reading skills.
