Deciding between two testing methods comes down to accuracy, cost and admissibility, and this guide compares EyeDetect head to head with a conventional lie detector test.
Two lie detection technologies — different science, different costs, different legal standing. This expert guide compares EyeDetect ocular-motor deception testing against traditional polygraph examination across every metric that matters: accuracy, admissibility, examiner requirements, cost, and real-world use cases.
TL;DR — The Short Version
- Polygraph accuracy averages 89% for event-specific diagnostic tests (confidence interval 83–95%) and 85% for multi-issue screening, according to the APA's comprehensive meta-analysis of 3,723 examinations.
- EyeDetect reports 86–88% accuracy for screening tests and up to 90% for specific-issue diagnostic tests, though independent validation remains limited.
- Polygraph results are admissible in some jurisdictions under stipulation or specific conditions. EyeDetect has virtually no legal admissibility precedent.
- EyeDetect costs roughly $70–$150 per test; a professional polygraph exam typically costs $300–$800 or more.
- For legally sensitive or high-stakes situations, the polygraph remains the gold standard. EyeDetect works best as a high-volume preliminary screening tool.
- When used together in a layered screening approach, Converus claims the combined outcome confidence can reach 97–99% based on Bayesian probability models.

Overview: Two Technologies, One Goal
The Quest to Detect Deception
For as long as human societies have existed, there has been a need to determine whether someone is telling the truth. From ancient trial by ordeal to modern psychophysiological testing, the methods have evolved dramatically, but the goal remains the same: find a reliable, objective way to distinguish truth from deception.
Today, two technologies dominate the credibility assessment landscape: the polygraph (commonly known as the lie detector test) and EyeDetect, a newer ocular-motor deception test developed by Converus, Inc. Both attempt to measure involuntary physiological responses associated with deception, but they do so through fundamentally different mechanisms, at different price points, and with different levels of research backing and legal standing.
The polygraph has been the primary credibility assessment tool worldwide for over a century. It measures cardiovascular activity, respiratory patterns, and electrodermal (sweat gland) responses through sensors attached to the body. A 2021 peer-reviewed meta-analysis found resident polygraph examiners in 65 countries, with 24 professionally recognized training schools and 12 professional organizations with international memberships Verified State-by-State Polygraph Rules & Lie Detector Tests in US
Confirms New Mexico as the only state generally allowing polygraph results in judicial processes and provides state licensing details. Many states allow polygraph evidence when both parties stipulate to its admission prior to testing. For international applications, see our guides on polygraph admissibility in the Philippines and polygraph testing in Zambia.
Stipulated polygraphs — in many jurisdictions, if both prosecution and defense agree before testing that the results will be admissible, courts will accept the results.
Probation and parole — polygraph testing is widely used and mandated in post-conviction supervision, particularly in sex offender management programs (PCSOT). Research has demonstrated that polygraph testing produces actionable information for risk management Verified Eye Scan EyeDetect Lie Detector (British Polygraph Society Review)
Confirms that EyeDetect combined accuracy claims only apply when both tests agree, and that tests are nullified when results disagree. The examiner's expertise in question formulation, rapport building, and behavioral observation adds significant value.
EyeDetect's automated process eliminates the interview component entirely, which means it cannot produce the same depth of information. For situations where information gain — not just a pass/fail result — is the primary goal, the polygraph's more comprehensive process may provide superior value despite the higher cost. For organizations screening large numbers of candidates where a basic pass/fail determination suffices as an initial filter, EyeDetect's cost advantage becomes compelling.
Examiner Training and Requirements
Polygraph Examiner Training
Becoming a qualified polygraph examiner requires substantial education and training. Candidates must complete a minimum of 400 hours of training at an APA-accredited polygraph school Verified Eye Scan EyeDetect Lie Detector (British Polygraph Society Review)
Confirms that EyeDetect combined accuracy claims only apply when both tests agree, and that tests are nullified when results disagree.
In the recommended layered model, EyeDetect is administered first as a cost-effective initial screening step. Subjects who pass then proceed to a full polygraph examination. This approach filters out deceptive individuals early, reduces overall screening costs, and maximizes accuracy for those who complete both tests.

Can EyeDetect results be used in court?
As of 2026, EyeDetect has virtually no established legal precedent for court admissibility. No significant court decisions have established admissibility under Daubert or Frye standards in any U.S. jurisdiction. Federal regulations, including DoD Directive 5210.91, currently prohibit the use of any credibility assessment technology other than the polygraph for government screening purposes [17]Verified Lie Detector Firm Lobbies CIA, DOD on Automated Eye-Scanning Tech
Confirms federal prohibitions on non-polygraph credibility assessment technologies and advisory board skepticism about EyeDetect's evidence base. The polygraph, by contrast, has an extensive legal framework across many jurisdictions.
How much does each test cost?
EyeDetect screening tests typically cost around $70 per test plus initial equipment investment of approximately $4,000 [22]Verified Criminals watch out — because the eyes don't lie (Daily Herald)
Confirms EyeDetect hardware cost of $4,000 and per-test cost of around $70, Ohio court submission, and law enforcement adoption. A professional polygraph examination typically costs $300 to $800 or more, depending on complexity, location, and examiner qualifications. The polygraph's higher cost reflects the extensive examiner time required for the pre-test interview, multiple chart collections, numerical scoring, and post-test discussion.
Can EyeDetect and polygraph be used together?
Yes, and this layered approach may represent the most effective use of both technologies. Using the Bayesian successive hurdles model, when a subject passes both an EyeDetect test and a polygraph test, the outcome confidence can reach 97–99% according to research published in the AAPP Journal [3]Verified Low Base Rate Screening Survival Analysis & Successive Hurdles
Confirms that combined EyeDetect and polygraph use can produce outcome confidence of 97–99% using Bayesian successive hurdles model. The recommended approach uses EyeDetect as a cost-effective initial screen, followed by a full polygraph examination for subjects who pass.
How long does each test take?
An EyeDetect test takes approximately 30–40 minutes from start to finish, including a brief orientation, 15–30 minutes of automated testing, and about 5 minutes for algorithmic scoring. A professional polygraph examination typically takes 90 minutes to 3 hours, including a detailed pre-test interview (30–90 minutes), multiple chart collections, numerical scoring, and a post-test discussion.
What training is required to administer each test?
Polygraph examiners must complete a minimum of 400 hours of training at an APA-accredited polygraph school [26]Verified PEAK Basic Polygraph Examiner's Course
Confirms APA-accredited basic polygraph examiner course consists of a minimum of 400 hours, typically followed by supervised internships and ongoing continuing education of at least 30 hours every two years [27]Verified Policy for APA Continuing Education Hours

EyeDetect standard proctors can be trained in approximately one day, with advanced training taking 3 additional days for those already trained as polygraph examiners [11]Verified EyeDetect+ Revolutionizes Polygraph Technology with Less-Invasive Data Collection Methods
Confirms EyeDetect+ accuracy of 87–91% depending on test type, less-invasive sensor design, and 20–45 minute test duration.
Can nervousness affect the accuracy of these tests?
Both technologies address the nervousness factor through their design. The polygraph uses comparison questions specifically designed to account for general test anxiety — the examiner compares reactions to relevant questions against reactions to comparison questions, effectively controlling for baseline nervousness. EyeDetect's automated, non-invasive process may reduce test anxiety for some subjects since there is no examiner present during testing and no sensors attached to the body. Learn more in our guide on whether nervousness can influence a polygraph test.
Which technology should I choose for my situation?
For legally sensitive matters, criminal defense, specific-issue investigations, or situations where the results may need to be presented in court, the polygraph is the clear choice due to its established legal framework, higher accuracy in specific-issue testing, and depth of information provided through the examiner interview. For high-volume pre-employment screening where cost and speed are priorities, EyeDetect offers compelling advantages. For maximum accuracy and confidence, use both technologies in a layered approach.
