Why Couples in Nevada Choose Polygraph Testing for Infidelity
The Scale of Infidelity and the Need for Truth
Infidelity is far more common than most people realise, and Nevada couples are not immune. According to data from the General Social Survey, approximately 20% of men and 13% of women report having had sex with someone other than their spouse while married [1]Verified Institute for Family Studies — Who Cheats More: Demographics of Cheating in America

Nevada's Rigorous Polygraph Regulation: The PILB Advantage
NRS Chapter 648: Your Legal Protection
Nevada stands out among states for its comprehensive regulation of polygraph examiners. Under NRS Chapter 648, the purpose of licensing polygraphic examiners is explicitly "to protect the public safety and general welfare of the people of this State" [8]Verified Nevada Revised Statutes Chapter 648 — Polygraphic Examiners
Confirms NRS 648 purpose of licensing polygraph examiners to protect public safety and welfare of the people of the state. No person may engage in the business of polygraphic examiner without a PILB licence under NRS 648.060 [9]Verified NRS 648.060 — License Required for Polygraphic Examiners
Confirms no person may engage in polygraph business without PILB license under NRS 648.060. This means that every polygraph examiner operating legally in Nevada has been thoroughly vetted and meets stringent professional standards.
The PILB licensing requirements are substantial. Before the Board grants any licence, applicants must be at least 21 years of age, be a citizen of the United States or lawfully entitled to remain and work in the United States, and undergo a criminal history background check [10]Verified Nevada PILB — Licensing Requirements
Confirms licensing requirements including minimum age of 21, citizenship, and background checks. Applicants must also have completed successfully at least 24 hours of advanced polygraphic training acceptable to the Board during the two years immediately before the date of application [11]Verified Nevada PILB — Polygraph Examiner License Information
Confirms 24 hours of advanced polygraphic training required within 2 years before application. Additionally, they must provide evidence of completing a basic course of instruction in polygraphic examination from a school certified by the American Polygraph Association [12]Verified NAC 648.395 — Licensing: Required Instruction
Confirms applicants must complete basic course of instruction from trained to APA standards school.
Instrument Standards and Quality Assurance
Nevada goes further than most states in regulating not just the examiners but also the instruments they use. Under NRS 648.185, the PILB must approve all polygraph instruments, which must be capable of recording cardiovascular activity, respiratory activity, and changes in skin resistance [13]Verified NRS 648.185 — Approval of Polygraph Required
Confirms PILB approval required for all polygraph instruments including recording of cardiovascular, respiratory, and skin resistance activity. The Nevada Administrative Code requires that a polygraphic examiner shall verify that a polygraphic instrument meets accuracy standards at least once during each 30 days the instrument is in use and maintain a record of that verification [14]Verified NAC 648.365 — Standards of Accuracy and Reliability of Instruments

The PILB has reported to the Nevada Legislature that there are inherent risks to public safety without proper licensing, as anyone could otherwise offer polygraph services without adequate training or oversight [15]Verified Nevada PILB Report to Legislature — Risk Assessment
Confirms inherent public safety risks without proper licensing of polygraph examiners in Nevada. This regulatory framework gives Nevada residents confidence that their infidelity polygraph exam will be conducted with properly calibrated equipment by a qualified, licensed professional. For more information on Nevada's complete polygraph legal framework, visit our polygraph test in Nevada booking guide.
Examinee Rights Under Nevada Law
Nevada law provides robust protections for anyone undergoing a polygraph examination. Under NRS 648.189, a polygraphic examination must not be conducted unless the person examined is advised of the purpose of the examination, and the person examined consents to it in writing [16]Verified NRS 648.189 — Explanation of Purpose of Examination; Consent
Confirms polygraphic examination must not be conducted unless person is advised of purpose and consents in writing. The examination cannot be conducted on anyone under 18 years of age without written parental consent [16]Verified NRS 648.189 — Explanation of Purpose of Examination; Consent
Confirms polygraphic examination must not be conducted unless person is advised of purpose and consents in writing.
Furthermore, NRS 648.187 requires that the examiner or intern shall, before beginning a polygraphic examination, inform the person examined that they have the right to refuse to answer incriminating or degrading questions [17]Verified NRS 648.187 — Right to Refuse Incriminating Questions
Confirms person examined must be advised of right to refuse incriminating or degrading questions under Nevada law. These protections ensure that infidelity polygraph exams are always voluntary, transparent, and conducted with full informed consent.

How Accurate Are Infidelity Polygraph Tests?
APA Research and Accuracy Data
The accuracy of polygraph testing has been extensively studied, and the results strongly support its value for specific-issue testing like infidelity examinations. The American Polygraph Association (APA) conducted a comprehensive meta-analytic survey examining criterion accuracy across validated polygraph techniques [18]Verified American Polygraph Association — Polygraph Validity Research
Confirms 89% aggregated accuracy for specific-issue diagnostic testing with 83-95% confidence interval and 11% inconclusive rate. The data showed that techniques intended for event-specific (single-issue) diagnostic testing produced an aggregated decision accuracy of 89%, with a confidence interval of 83% to 95% [18]Verified American Polygraph Association — Polygraph Validity Research
Confirms 89% aggregated accuracy for specific-issue diagnostic testing with 83-95% confidence interval and 11% inconclusive rate.
Researchers conducted 12 studies of the validity of field examinations, following 2,174 field examinations, providing an average accuracy of 98% [19]Verified Global Polygraph Network — About Polygraph Accuracy
Confirms 98% average accuracy in 12 field studies, 92% in independent analyses, and 90%+ requirement for APA-validated specific-issue techniques. Independent analyses of 1,609 sets of charts from field examinations confirmed by independent evidence produced an average accuracy of 92% [19]Verified Global Polygraph Network — About Polygraph Accuracy
Confirms 98% average accuracy in 12 field studies, 92% in independent analyses, and 90%+ requirement for APA-validated specific-issue techniques. In 2010, the APA established standards requiring that any polygraph technique used in specific-issue testing must achieve a minimum accuracy rate of 90% to be considered validated [19]Verified Global Polygraph Network — About Polygraph Accuracy
Confirms 98% average accuracy in 12 field studies, 92% in independent analyses, and 90%+ requirement for APA-validated specific-issue techniques. These standards ensure that the techniques used in your infidelity exam meet rigorous scientific benchmarks.
For a deeper understanding of the factors influencing test outcomes, see our guide on 9 factors that affect lie detector test results.
Why Specific-Issue Tests Excel for Infidelity
Infidelity polygraph examinations are typically administered as specific-issue tests, which is the testing format that achieves the highest level of accuracy. Most current research on polygraph is contingent upon the use of a specific-issue format with one relevant question, and adding even one question to a specific-issue test doubles the error rate [19]Verified Global Polygraph Network — About Polygraph Accuracy
Confirms 98% average accuracy in 12 field studies, 92% in independent analyses, and 90%+ requirement for APA-validated specific-issue techniques. This is why professional examiners carefully design the test to focus on the core issue of infidelity rather than attempting to cover numerous unrelated topics.
The APA notes that while no polygraph technique is infallible, "when administered by a competent examiner who follows proper protocols, polygraph testing is one of the most accurate means available to determine truth and deception" [20]Verified American Polygraph Association — Polygraph Frequently Asked Questions
Confirms polygraph examination phases including pre-test interview, chart collection, and data analysis, and that no surprise questions are used. Infidelity questions are typically direct and factual, such as whether sexual contact occurred with a specific person or during a specific timeframe, making them well-suited to the specific-issue format that produces the highest accuracy. To understand what questions may be asked during your exam, explore our comprehensive guide on lie detector test questions for couples.
What to Expect During an Infidelity Polygraph in Nevada
The Pre-Test Interview
A typical infidelity polygraph examination in Nevada takes approximately 2 to 3 hours from start to finish. The process begins with a pre-test interview, during which the polygraph examiner will complete required paperwork, discuss the test with the examinee, and answer any questions [20]Verified American Polygraph Association — Polygraph Frequently Asked Questions
Confirms polygraph examination phases including pre-test interview, chart collection, and data analysis, and that no surprise questions are used. During this phase, the examiner will discuss the test questions and familiarise the examinee with the testing procedure [20]Verified American Polygraph Association — Polygraph Frequently Asked Questions
Confirms polygraph examination phases including pre-test interview, chart collection, and data analysis, and that no surprise questions are used. There are no surprise or trick questions — every question is reviewed and discussed before testing begins [20]Verified American Polygraph Association — Polygraph Frequently Asked Questions
Confirms polygraph examination phases including pre-test interview, chart collection, and data analysis, and that no surprise questions are used.
The pre-test interview is a critical component of the examination. It establishes rapport between the examiner and examinee, ensures informed consent under NRS 648.189 [16]Verified NRS 648.189 — Explanation of Purpose of Examination; Consent
Confirms polygraphic examination must not be conducted unless person is advised of purpose and consents in writing, and allows the examiner to explain the physiological measures that will be recorded. The examiner will also confirm that the examinee is not under the influence of medications or substances that could affect the test, and that no arguments or emotional disruptions occurred immediately before the examination, as pre-test arguments can skew results [21]Verified Family and Life Solutions — Polygraph Testing in Infidelity Recovery
Confirms polygraph is used to confirm betrayer's truthfulness in counselling and that pre-test arguments can skew results.
The Chart Collection Phase
During the chart collection phase, the examiner administers and collects a number of polygraph charts [20]Verified American Polygraph Association — Polygraph Frequently Asked Questions
Confirms polygraph examination phases including pre-test interview, chart collection, and data analysis, and that no surprise questions are used. The polygraph instrument records multiple physiological channels simultaneously, including thoracic and abdominal respiration patterns, cardiovascular activity, electrodermal (skin conductance) activity, and seat activity via a motion sensor [22]Verified APA Standards of Practice (2019)
Confirms thoracic and abdominal respiration recording requirements, seat activity sensor, and APA research standards. These are involuntary physiological responses that occur when a person is being deceptive.
For infidelity-specific examinations, the relevant questions focus on the particular act or behaviour under investigation [20]Verified American Polygraph Association — Polygraph Frequently Asked Questions
Confirms polygraph examination phases including pre-test interview, chart collection, and data analysis, and that no surprise questions are used. Questions are designed to be objective, factual, and require a simple yes or no answer. Subjective questions about emotions or feelings are not included, as they cannot be reliably measured [19]Verified Global Polygraph Network — About Polygraph Accuracy
Confirms 98% average accuracy in 12 field studies, 92% in independent analyses, and 90%+ requirement for APA-validated specific-issue techniques. The examiner will typically collect three to five charts to ensure sufficient data for an accurate analysis.
Results and Post-Test Process
Following chart collection, the examiner analyses the physiological data using validated scoring methods. Results for infidelity polygraph examinations in Nevada are typically delivered the same day, allowing couples to begin processing the outcome immediately.
The examiner will provide a professional opinion classifying the results as either Deception Indicated (DI), No Deception Indicated (NDI), or Inconclusive (INC). If results are inconclusive, the APA meta-analysis found an estimated inconclusive rate of approximately 11% for specific-issue tests [18]Verified American Polygraph Association — Polygraph Validity Research
Confirms 89% aggregated accuracy for specific-issue diagnostic testing with 83-95% confidence interval and 11% inconclusive rate. An inconclusive result does not indicate deception — it simply means the physiological data was insufficient for a definitive opinion. Many examiners will offer the option to retest if results are inconclusive.
Legal Considerations for Infidelity Polygraphs in Nevada
Private Use vs. Legal Proceedings
Most infidelity polygraph tests in Nevada are conducted for private, personal use rather than as part of legal proceedings. When used privately, the results serve as a tool for personal decision-making and relationship resolution. There are no legal restrictions on taking a voluntary polygraph test for personal relationship matters in Nevada.
However, if you anticipate that polygraph results might become relevant to a divorce or custody case, it is wise to consult with a family law attorney beforehand. Under NRS 648.183, a polygraphic examination must meet minimum standards and be administered by a licensed or exempt and qualified person before it can be considered or accepted into evidence [23]Verified NRS 648.183 — Polygraphic Examination Standards for Evidence
Confirms polygraph must meet minimum NRS standards and be administered by licensed person for evidentiary use.
Admissibility in Nevada Courts
Nevada is one of the states that permits polygraph evidence under specific conditions. In Jackson v. State (2000), the Nevada Supreme Court confirmed that polygraph results may be considered reliable "when taken under proper conditions and with proper safeguards in place" [24]Verified Jackson v. State — Nevada Supreme Court (2000)
Confirms Nevada rule that polygraph results may be reliable under proper conditions with written stipulation requirement for admissibility. However, the safeguards include the requirement of a written stipulation signed by all parties providing for the submission to the test [24]Verified Jackson v. State — Nevada Supreme Court (2000)
Confirms Nevada rule that polygraph results may be reliable under proper conditions with written stipulation requirement for admissibility. Absent a written stipulation, polygraph evidence may properly be excluded [24]Verified Jackson v. State — Nevada Supreme Court (2000)
Confirms Nevada rule that polygraph results may be reliable under proper conditions with written stipulation requirement for admissibility.
This stipulation requirement was originally established in Corbett v. State (1978) and has been consistently upheld in subsequent Nevada case law [24]Verified Jackson v. State — Nevada Supreme Court (2000)
Confirms Nevada rule that polygraph results may be reliable under proper conditions with written stipulation requirement for admissibility. For family law matters, this means both spouses would need to agree in advance that the polygraph results will be admissible. While this stipulation requirement may seem restrictive, it actually serves as a quality assurance mechanism — ensuring that only properly conducted examinations are presented as evidence.
Approximately half of U.S. states allow polygraph evidence to be used in court cases when both parties agree to it [25]Verified American Psychological Association — Do Lie Detectors Work?
Confirms about half of U.S. states allow polygraph evidence when both parties agree to it. Nevada's approach reflects a balanced standard that recognises the value of polygraph evidence while maintaining appropriate judicial safeguards.
Your Right to Refuse
No one can be forced to take a polygraph test against their will [26]Verified LegalMatch — Admissibility of Polygraph Tests in Court
Confirms you cannot be forced to take a polygraph test against your will. Under the Fifth Amendment and Nevada law, polygraph testing is always voluntary. NRS 648.187 specifically requires that the person examined must be advised of their right to refuse to answer incriminating or degrading questions [17]Verified NRS 648.187 — Right to Refuse Incriminating Questions
Confirms person examined must be advised of right to refuse incriminating or degrading questions under Nevada law. If you are being pressured into taking a test, consult with an attorney about your rights.
Preparing for Your Infidelity Polygraph Test
Before the Examination
Proper preparation helps ensure accurate results. Here are essential steps to take before your infidelity polygraph in Nevada:
Get a full night's sleep the night before. Fatigue can affect physiological baselines and potentially produce inconclusive results. Avoid alcohol and recreational drugs for at least 24 hours before the test, as these substances can alter autonomic nervous system responses.
Avoid arguments or emotionally charged conversations on the day of the exam. Research confirms that pre-test arguments can skew results — one study noted that a man who had been upset and crying during an argument just before a test showed deceptive responses despite actually telling the truth [21]Verified Family and Life Solutions — Polygraph Testing in Infidelity Recovery
Confirms polygraph is used to confirm betrayer's truthfulness in counselling and that pre-test arguments can skew results. Arrive at the testing location calm and well-rested.
If you are taking medications, inform the examiner beforehand. While most medications do not affect polygraph results, certain substances that impact the autonomic nervous system may need to be disclosed. Pregnant women should also consult with the examiner about testing suitability [21]Verified Family and Life Solutions — Polygraph Testing in Infidelity Recovery
Confirms polygraph is used to confirm betrayer's truthfulness in counselling and that pre-test arguments can skew results.
Understanding the Questions
All test questions will be reviewed with you during the pre-test interview before any testing begins. There are no surprise or trick questions [20]Verified American Polygraph Association — Polygraph Frequently Asked Questions
Confirms polygraph examination phases including pre-test interview, chart collection, and data analysis, and that no surprise questions are used. For infidelity-specific tests, relevant questions tend to require only a yes or no answer and are direct and factual.
Typical infidelity polygraph questions include inquiries such as whether you have had sexual contact with someone other than your spouse or partner during a specific timeframe. Questions about feelings, emotions, or subjective experiences are not asked because they cannot be reliably measured. The examiner will work with you to ensure you understand every question clearly before testing begins.

Confirms significant number of tests administered at therapist request and therapeutic disclosure exam options. This verification provides the betrayed partner with confidence that the full truth has been shared.
For couples in open relationships where boundary violations are the concern, our guide on open relationship boundaries and polygraph testing offers tailored guidance.
Seasonal Patterns and When to Test
It is worth noting that demand for infidelity polygraph testing follows seasonal patterns. Our data shows that polygraph bookings spike after summer holidays and the Christmas period, when increased social opportunities and travel create conditions where infidelity may be more likely to occur.
Regardless of timing, the key is not to delay once the decision to test has been made. The sooner a polygraph can be administered after concerns arise, the more useful the results will be for the couple's recovery process. If you suspect a workplace affair, early testing can help address the issue before it escalates further.

Frequently Asked Questions
Do I need to tell my partner I'm arranging a polygraph test?
For a relationship polygraph to be effective, the person taking the test must participate voluntarily and with informed consent. Under Nevada law (NRS 648.189), the purpose of the examination must be explained and consent obtained in writing before testing begins [16]Verified NRS 648.189 — Explanation of Purpose of Examination; Consent
Confirms polygraphic examination must not be conducted unless person is advised of purpose and consents in writing. The person being tested must always know they are taking a polygraph. However, some providers offer arrangements where the requesting partner can observe remotely or receive verbal updates immediately after the examination.
