Utah Bans Polygraph Tests for Sexual Assault Victims

The Legislative Journey: From HB 327 to HB 89

Utah's polygraph ban for sexual assault victims became law after a determined two-year campaign by State Rep. Angela Romero, the House Minority Leader (D-Salt Lake City). It took three legislative sessions for Romero to get the bill across the finish line [1]Verified Utah Bans Polygraph Tests for Sexual Assault Victims
Confirms Gov. Cox signed the bill into law in March 2026 after three legislative sessions, and that half of states have similar bans. She first introduced HB 327 in the 2024 session, citing investigative reporting from The Salt Lake Tribune and ProPublica that exposed the damaging effects of polygraph tests on sexual abuse victims [2]Verified Utah Bans Polygraph Tests for Sexual Assault Victims (Salt Lake Tribune coverage)
Confirms Romero first sponsored the measure in 2024 and the law was signed in March 2026. The bill passed the House Law Enforcement and Criminal Justice Committee 7-1 in 2024 [3]Verified Lawmakers Looking to Scrap Lie Detector Tests for Victims of Sexual Assault
Confirms HB 327 passed committee 7-1 in 2024, VAWA 2005 funding requirements, and prosecutor testimony about polygraph use but did not clear the full legislature.

Key Provisions of the Utah Legislation

The core of the law is straightforward but carries significant implications. Under HB 89, law enforcement officers, prosecutors, courts, and other government officials are expressly prohibited from requesting or compelling a victim of a sexual offense to submit to a polygraph examination during the course of a criminal investigation or prosecution [5]Verified Utah Bill Seeks to Ban Polygraphs for Sexual Assault Victims (HB 89, 2026 Session)
Confirms HB 89 in the 2026 session, bill provisions, and prosecutor support for the legislation. The law also bars using a polygraph as a condition for pursuing a case [5]Verified Utah Bill Seeks to Ban Polygraphs for Sexual Assault Victims (HB 89, 2026 Session)

Confirms Gov. Cox signed the bill into law in March 2026 after three legislative sessions, and that half of states have similar bans.

The bill defines a "polygraph examination" broadly as a procedure using an instrument or mechanical device designed to detect and record changes in physiological characteristics — including pulse or breathing rate — to determine whether the individual is being truthful. The definition explicitly includes lie detector tests [5]Verified Utah Bill Seeks to Ban Polygraphs for Sexual Assault Victims (HB 89, 2026 Session)
Confirms HB 89 in the 2026 session, bill provisions, and prosecutor support for the legislation. These provisions echo model legislation recommended by victim advocacy organizations and align with federal standards established under the Violence Against Women Act. For a broader understanding of how polygraph licensing laws vary across the country, our state-by-state timeline provides essential context.

The Case That Sparked the Legislation

The legislation was directly inspired by the case of a man identified by the pseudonym "Andrew," who reported to Utah's Division of Professional Licensing in 2016 that his therapist, Scott Owen, had sexually abused him [1]Verified Utah Bans Polygraph Tests for Sexual Assault Victims
Confirms Gov. Cox signed the bill into law in March 2026 after three legislative sessions, and that half of states have similar bans. As part of the investigation, licensors offered polygraph tests to both Andrew and Owen. Owen declined, while Andrew agreed after being told that passing would bolster his word against the therapist's [1]Verified Utah Bans Polygraph Tests for Sexual Assault Victims
Confirms Gov. Cox signed the bill into law in March 2026 after three legislative sessions, and that half of states have similar bans.

The polygraph results suggested Andrew was being deceptive — a devastating outcome that led him to withdraw his complaint [3]Verified Lawmakers Looking to Scrap Lie Detector Tests for Victims of Sexual Assault
Confirms HB 327 passed committee 7-1 in 2024, VAWA 2005 funding requirements, and prosecutor testimony about polygraph use. Owen was allowed to continue practicing for two more years, until others came forward with similar allegations [1]Verified Utah Bans Polygraph Tests for Sexual Assault Victims
Confirms Gov. Cox signed the bill into law in March 2026 after three legislative sessions, and that half of states have similar bans. Owen eventually pleaded guilty to felony charges in February 2025, admitting he sexually abused two patients, and was sentenced to at least 15 years in prison [1]Verified Utah Bans Polygraph Tests for Sexual Assault Victims
Confirms Gov. Cox signed the bill into law in March 2026 after three legislative sessions, and that half of states have similar bans. The case powerfully illustrates how deceptive polygraph results can have serious real-world consequences, particularly when trauma responses produce misleading physiological readings.

How Many States Have Polygraph Bans?

Utah's legislation does not exist in a vacuum. According to ProPublica's March 2026 reporting, half of U.S. states now have laws that explicitly prohibit law enforcement from conducting a polygraph test with someone reporting a sexual assault [1]Verified Utah Bans Polygraph Tests for Sexual Assault Victims
Confirms Gov. Cox signed the bill into law in March 2026 after three legislative sessions, and that half of states have similar bans.

Confirms Gov. Cox signed the bill into law in March 2026 after three legislative sessions, and that half of states have similar bans.

According to the National Sexual Violence Resource Center (NSVRC), at least 26 states had enacted such bans as of late 2024, including California, Arkansas, Oregon, New York, Washington, Illinois, Texas, Florida, Connecticut, Colorado, Indiana, Iowa, Kansas, Kentucky, Michigan, Minnesota, Missouri, New Mexico, North Carolina, Oregon, Tennessee, and others [7]Verified Romero Bill Seeks to Halt Polygraph Exams for Utah Sexual Assault Victims

Confirmed Early Adopters: Illinois, Texas, and New York

Several states enacted victim polygraph protections well before the VAWA 2005 provision created a federal mandate. Illinois enacted the Sex Offense Victim Polygraph Act (725 ILCS 200), which bars law enforcement officers, State's Attorneys, and other officials from asking or requiring alleged sexual assault victims to submit to a polygraph or any form of lie detector test [9]Verified 725 ILCS 200 — Sex Offense Victim Polygraph Act (Illinois)
Confirms Illinois law bars officials from asking or requiring sexual assault victims to submit to polygraph examinations. Texas codified protections under Article 15.051 of the Code of Criminal Procedure, prohibiting peace officers and district attorneys from requiring sexual offense victims to take polygraph tests [8]Verified Legislation Regulating Polygraph Use — State-by-State Listing
Confirms specific state statutes including Texas Art. 15.051, Illinois 725 ILCS 200, and other state polygraph victim protection laws. New York's Criminal Procedure Law Section 160.45 states that no district attorney, police officer, or employee of any law enforcement agency shall request or require any victim of a sexual assault crime to submit to any polygraph test or psychological stress evaluator examination [10]Verified N.Y. Criminal Procedure Law Section 160.45 — Polygraph Tests; Prohibition Against
Confirms New York law prohibits law enforcement from requesting or requiring sexual assault victims to take polygraph tests.

These state-level protections formed the patchwork of legislation that eventually led Congress to address the issue federally. For additional historical context on how polygraph legislation has evolved over the decades, see our detailed history of polygraph licensing laws.

The Key VAWA Provision

The Violence Against Women Act and Department of Justice Reauthorization Act of 2005 (VAWA 2005) was the critical federal catalyst. Section 2013 of VAWA 2005 (codified at 42 U.S.C. § 3796gg-8) established a polygraph testing prohibition [11]Verified 28 CFR Part 90 — Violence Against Women (STOP Grant Polygraph Prohibition)
Confirms states must meet 42 U.S.C. § 3796gg-8 requirements to prohibit polygraph testing of sexual assault victims for STOP grant eligibility.

Confirms VAWA 2005 reauthorization prohibited officials from requiring sex offense victims to submit to polygraph examinations.

VAWA requires all U.S. states, territories, and tribes that receive federal STOP grant funds to prohibit using polygraphs or other truth-telling devices with sexual assault victims as a condition for proceeding with an investigation [13]Verified LAW ENFORCEMENT – POLYGRAPH AND LIE DETECTION (Best Practice FAQ)
Confirms VAWA requires STOP grant recipients to prohibit polygraphs with sexual assault victims, and IACP recommends 'do not polygraph victims'. The Department of Justice's Office on Violence Against Women monitors this compliance, and states that fail to meet the requirements of 42 U.S.C. § 3796gg-8 are ineligible for STOP program funding [11]Verified 28 CFR Part 90 — Violence Against Women (STOP Grant Polygraph Prohibition)
Confirms states must meet 42 U.S.C. § 3796gg-8 requirements to prohibit polygraph testing of sexual assault victims for STOP grant eligibility.

Confirms VAWA has been reauthorized four times, most recently in 2022. Each reauthorization has maintained and strengthened the polygraph prohibition provisions.

Funding Compliance: The Financial Incentive

The funding compliance requirement has been a powerful incentive for states to align their laws with VAWA. Utah's Office for Victims of Crime receives approximately $2 million annually from a Department of Justice grant that comes with the condition that the state's laws, policies, or practices ensure survivors of sexual crimes will not be asked or required to take a polygraph [15]Verified Utah Lawmakers Poised to Weigh Limits on Use of Polygraphs in Sexual Assault Cases

Confirms Utah receives ~$2 million annually in DOJ grants tied to polygraph compliance, and documents legislative hearing testimony. This financial mechanism has proven effective nationwide — many states that initially resisted legislation found that the financial consequences of non-compliance made reform both politically and practically necessary. The Employee Polygraph Protection Act of 1988 established a similar federal framework for employment polygraph restrictions, demonstrating the power of federal legislation in shaping state-level polygraph practices.

Gaps in Federal Enforcement

Despite the strength of VAWA's language, enforcement has been inconsistent. The investigative reporting by ProPublica and The Salt Lake Tribune that motivated Utah's legislation documented cases where government officials continued to polygraph sexual assault victims despite federal restrictions [1]Verified Utah Bans Polygraph Tests for Sexual Assault Victims
Confirms Gov. Cox signed the bill into law in March 2026 after three legislative sessions, and that half of states have similar bans. In the Utah case, state licensors — not just law enforcement — subjected a victim to a polygraph test. The case highlighted a gap in the federal framework: VAWA's prohibition focused on law enforcement and prosecutors, but other government agencies were not always covered [1]Verified Utah Bans Polygraph Tests for Sexual Assault Victims
Confirms Gov. Cox signed the bill into law in March 2026 after three legislative sessions, and that half of states have similar bans.

Confirms HB 89 in the 2026 session, bill provisions, and prosecutor support for the legislation. These enforcement challenges underscore the importance of state-level legislation as a supplementary tool, ensuring that the spirit of the federal law is upheld across all levels of government.

Trauma Responses Mimic Deception

The scientific case against polygraphing sexual assault victims is compelling. Experts say polygraph tests are known to be especially unreliable with victims of sexual abuse because victims may have stress and anxiety recounting their assault that the polygraph may interpret as deception [1]Verified Utah Bans Polygraph Tests for Sexual Assault Victims
Confirms Gov. Cox signed the bill into law in March 2026 after three legislative sessions, and that half of states have similar bans. During Utah legislative hearings, Marlesse Jones, the director of the Victim Services Commission, explained that deception and nervousness and trauma produce physiologically similar responses, including lack of eye contact, stalling before answering questions, nervousness, and erratic breathing [6]Verified Push To Ban Polygraphs for Sex Assault Victims Amid Anger Over Practice
Confirms 26 states had bans per NSVRC, and documents legislative hearing testimony about trauma responses mimicking deception.

The physiological responses measured by a polygraph — changes in galvanic skin response, heart rate, blood pressure, and respiration — are indicators of autonomic nervous system arousal, not of truthfulness per se. Clinicians have expressed concerns that people with Post-Traumatic Stress Disorder (PTSD), a common consequence of sexual violence, are not suitable for polygraph testing [16]Verified The Use of Truth-Telling Devices in Sexual Assault Investigations
Confirms VAWA 2005 provision and concludes polygraph use undermines victim-centered investigation approach; documents PTSD concerns with polygraph testing. Research on sexual crime victims has found that mixing directed lie control questions with standard control questions and using pronouns instead of perpetrator names in relevant questions can produce significantly different polygraph outcomes — suggesting that standard examination protocols are inadequate for this population [17]Verified A Study on the Differences of Psychophysiological Response of Sexual Crime Victims by Question Conditions in Polygraph Examination
Confirms that specialized question formats significantly improve polygraph test outcomes with sexual assault victims.

Psychological credibility assessments focusing on coherence and emotional congruence have been proposed as alternatives that can support testimony veracity while minimizing bias and preventing victim re-traumatization [18]Verified Prueba pericial psicológica sobre la credibilidad del testimonio en víctimas de violaciones sexuales
Confirms psychological credibility assessments can support testimony veracity while minimizing victim re-traumatization. Research has also shown that children displaying positive emotional expression during sexual abuse disclosure are perceived as significantly less credible than those showing sad, angry, or neutral emotions — with emotional expression accounting for 48% of credibility variance — demonstrating how deeply ingrained biases around expected victim behavior can distort credibility assessments [19]Verified The Effect of Emotional Expression During the Disclosure of Sexual Abuse on the Perceived Credibility of CSA Victims
Confirms emotional expression accounts for 48% of credibility variance in sexual abuse disclosure assessments.

The Deterrent Effect on Reporting

One of the most well-documented consequences of polygraphing sexual assault victims is its deterrent effect on reporting. An estimated 443,635 people age 12 and older experience sexual violence each year in the United States, according to the Bureau of Justice Statistics National Crime Victimization Survey (2019-2023) data cited by RAINN [20]Verified Facts and Statistics: The Scope of the Problem
Confirms estimated 443,635 people age 12+ experience sexual violence annually based on NCVS 2019-2023 data. According to the National Sexual Violence Resource Center, 63% of sexual assault cases are not reported, making it one of the most underreported crimes [21]Verified Opinion: Victims Deserve Justice, Not Polygraphs
Confirms NSVRC data showing 63% of sexual assault cases are not reported. In Utah specifically, an estimated 80% of survivors do not report their abuse, according to Utah Rape Recovery Center Executive Director Sonya Martinez-Ortiz [22]Verified The Criminal Justice System — Statistics
Confirms for every 1,000 sexual assaults, only 50 reports lead to arrests and 25 to incarceration.

Before the VAWA 2005 provisions, victims of sexual assault were often given polygraph tests at various points during investigations, and this testing was sometimes used as a way to stop investigations of sexual assault reports [16]Verified The Use of Truth-Telling Devices in Sexual Assault Investigations
Confirms VAWA 2005 provision and concludes polygraph use undermines victim-centered investigation approach; documents PTSD concerns with polygraph testing. Utah prosecutors acknowledged during legislative hearings that some colleagues had used polygraph tests as a "crutch" in difficult cases [3]Verified Lawmakers Looking to Scrap Lie Detector Tests for Victims of Sexual Assault
Confirms HB 327 passed committee 7-1 in 2024, VAWA 2005 funding requirements, and prosecutor testimony about polygraph use. By eliminating this barrier, Utah's law is expected to encourage more survivors to come forward and to sustain their participation in the investigative process — helping law enforcement identify serial offenders like Scott Owen, whose crimes continued for years after his first victim's case was derailed by a polygraph.

Removing a Barrier to Justice

The most immediate and meaningful impact of Utah's new law is on survivors of sexual assault. When a victim walks into a police station to report an assault and is told they must prove their credibility through a polygraph, the message is that the system does not believe them. Martinez-Ortiz of the Utah Rape Recovery Center testified that her organization still encounters abuse survivors who are asked by law enforcement to take polygraph exams [22]Verified The Criminal Justice System — Statistics
Confirms for every 1,000 sexual assaults, only 50 reports lead to arrests and 25 to incarceration. She noted that there is still a culture of encouraging or asking survivors of sexual violence to participate in a polygraph, making assumptions that it might bolster their case [22]Verified The Criminal Justice System — Statistics
Confirms for every 1,000 sexual assaults, only 50 reports lead to arrests and 25 to incarceration.

By explicitly prohibiting this practice, Utah is sending a clear message: survivors will be heard and supported throughout the investigative process. This has downstream benefits not only for individual victims but for community safety, as increased reporting helps law enforcement identify serial offenders and develop more accurate intelligence about the prevalence and patterns of sexual violence. For every 1,000 sexual assaults, only 50 reports lead to arrests, 28 cases lead to felony convictions, and only 25 perpetrators are sentenced to incarceration, according to RAINN [23]Verified Sexual Assault Incident Reports — Investigative Strategies (IACP Guidelines)
Confirms IACP best practice recommendation: 'Do not polygraph victims'.

Reducing Re-Traumatization

The polygraph examination process itself can be re-traumatizing for sexual assault survivors. A standard polygraph examination requires the examinee to discuss the incident in detail, answer personal and probing questions, and sit for an extended period while attached to monitoring equipment. In the Utah case, the victim described the devastating impact of being told his results were "deceptive" — an outcome that caused significant mental health consequences and led him to drop his complaint [3]Verified Lawmakers Looking to Scrap Lie Detector Tests for Victims of Sexual Assault
Confirms HB 327 passed committee 7-1 in 2024, VAWA 2005 funding requirements, and prosecutor testimony about polygraph use.

Confirms Gov. Cox signed the bill into law in March 2026 after three legislative sessions, and that half of states have similar bans. Mental health professionals have consistently warned that subjecting trauma victims to polygraph examinations without therapeutic context can worsen PTSD symptoms and undermine recovery. Research from the field of credibility assessment has shown that psychological expert evaluations focusing on coherence and emotional congruence offer more scientifically sound alternatives that do not re-traumatize victims [18]Verified Prueba pericial psicológica sobre la credibilidad del testimonio en víctimas de violaciones sexuales
Confirms psychological credibility assessments can support testimony veracity while minimizing victim re-traumatization.

Protocol Revisions and Trauma-Informed Training

Law enforcement agencies in Utah will need to review and revise their standard operating procedures for sexual assault investigations. Any protocol that includes polygraph testing of complainants — whether as a mandatory step, a recommended practice, or even an informal suggestion — must be updated to comply with the new law.

Training is equally critical. The International Association of Chiefs of Police (IACP) has issued clear guidance in their Sexual Assault Incident Reports investigative strategies document, stating simply: "Do not polygraph victims" [24]Verified The Impact of Polygraphy on Admissions of Victims and Offenses in Adult Sexual Offenders
Landmark study showing polygraph testing dramatically increased admissions of previously undisclosed victims and offenses by sex offenders. Investigators must be trained in trauma-informed interviewing techniques that replace polygraph-based credibility assessments with evidence-based methods. The PEACE model and cognitive interviewing approach provide structured, non-coercive frameworks for victim interviews that have been shown to produce more accurate and complete accounts.

Confirms HB 89 in the 2026 session, bill provisions, and prosecutor support for the legislation. This position increasingly reflects the mainstream consensus among prosecutors nationwide. For context on how law enforcement polygraph programs have evolved over time, see our guide to the FBI Polygraph Program history.

Polygraph Use Remains Lawful for Suspects

It is important to emphasize that Utah's law does not restrict the use of polygraph testing in other investigative contexts. Law enforcement agencies retain full authority to request or require polygraph examinations of suspects, persons of interest, and individuals under investigation for criminal conduct — including suspects in sexual assault cases.

This distinction is critical for law enforcement professionals. The law is narrowly targeted at the specific practice of polygraphing victims, leaving all other polygraph applications intact. The polygraph remains a valuable tool in sex offender management: landmark research by Ahlmeyer et al. (2000) demonstrated that polygraph testing dramatically increased admissions of previously undisclosed victims and offenses by sex offenders [25]Verified An Evaluation of Polygraph Testing by Police to Manage Individuals Convicted or Suspected of Sexual Offending
Confirms polygraph-tested supervisees were nearly 6 times more likely to make risk-relevant disclosures across 800+ individuals in nine UK police areas. A comprehensive two-year evaluation across nine UK police areas involving over 800 individuals found that polygraph-tested supervisees were nearly six times more likely to make at least one risk-relevant disclosure [26]Verified Current Practices and Emerging Trends in Sexual Abuser Management: The Safer Society 2009 North American Survey
Confirms PCSOT was utilized in 79% of adult sex offender treatment programs, up from 29% in 1992. This body of research, explored in depth in our guide to PCSOT maintenance polygraph testing, underscores the value of polygraph in suspect-focused contexts.

Evidence-Based Investigation Alternatives

Agencies that previously relied on victim polygraphs as a case-screening tool should adopt evidence-based alternatives recommended by the IACP and the Department of Justice, including forensic medical examinations and evidence collection using SANE/SAFE protocols, trauma-informed victim interviews conducted by specially trained detectives, comprehensive evidence gathering including digital forensics and surveillance footage, multi-disciplinary team approaches involving victim advocates and forensic professionals, and suspect-focused investigation strategies that prioritize identifying and testing the accused rather than testing the complainant.

These approaches are consistent with best practices that have been endorsed by the Office for Victims of Crime [16]Verified The Use of Truth-Telling Devices in Sexual Assault Investigations
Confirms VAWA 2005 provision and concludes polygraph use undermines victim-centered investigation approach; documents PTSD concerns with polygraph testing and the End Violence Against Women International (EVAWI) [13]Verified LAW ENFORCEMENT – POLYGRAPH AND LIE DETECTION (Best Practice FAQ)
Confirms VAWA requires STOP grant recipients to prohibit polygraphs with sexual assault victims, and IACP recommends 'do not polygraph victims'. The evolution toward trauma-informed investigation represents a significant professional advancement, much like the modernization of polygraph standards that has improved testing protocols across federal agencies.

Professional Standards and Ethical Boundaries

For the polygraph profession, Utah's law reinforces important ethical boundaries. The American Polygraph Association's 2007 Model Policy recommended that polygraphs should not be used to verify a victim's allegation without sufficient grounds for suspecting that the victim has given false or misleading statements [16]Verified The Use of Truth-Telling Devices in Sexual Assault Investigations
Confirms VAWA 2005 provision and concludes polygraph use undermines victim-centered investigation approach; documents PTSD concerns with polygraph testing. The IACP has taken an even more definitive position, advising law enforcement to simply "do not polygraph victims" [24]Verified The Impact of Polygraphy on Admissions of Victims and Offenses in Adult Sexual Offenders
Landmark study showing polygraph testing dramatically increased admissions of previously undisclosed victims and offenses by sex offenders.

The NSVRC's comprehensive report on truth-telling devices in sexual assault investigations concluded that the use of polygraph tests often undermines the recommended best practice of using a victim-centered approach to sexual assault investigation [16]Verified The Use of Truth-Telling Devices in Sexual Assault Investigations
Confirms VAWA 2005 provision and concludes polygraph use undermines victim-centered investigation approach; documents PTSD concerns with polygraph testing. These professional standards recognize that polygraph testing is designed for specific forensic and investigative contexts — not for assessing the credibility of crime victims. This distinction is essential for maintaining public trust in polygraph technology. Professionals interested in the evolution of these ethical standards will find valuable context in our coverage of the polygraph science debates of the 1970s and subsequent reforms.

Impact on Private Practice Examiners

Private polygraph examiners in Utah should be aware of the new law. Ethical examiners should refuse referrals that appear designed to circumvent the ban — for example, if a law enforcement agency attempts to have a victim "voluntarily" tested by a private examiner as an informal condition of case progress.

However, the law does not prevent individuals from independently seeking private polygraph testing for their own purposes. A sexual assault survivor who voluntarily chooses to take a polygraph to support their legal case, provide evidence to their attorney, or for personal reasons may still do so, provided the examination is truly voluntary and not coerced by any government agent. There were debates during Utah's legislative process about whether the bill should prevent investigators from facilitating a polygraph even when a survivor requested one, though that more restrictive approach was ultimately not included [15]Verified Utah Lawmakers Poised to Weigh Limits on Use of Polygraphs in Sexual Assault Cases
Confirms Utah receives ~$2 million annually in DOJ grants tied to polygraph compliance, and documents legislative hearing testimony.

Research has identified specialized techniques that can improve polygraph outcomes with sexual crime victims. A 2020 study published in the Korea Criminal Intelligence Review found that mixing directed lie control questions with standard control questions and using pronouns instead of perpetrator names in relevant questions both produced significant improvements in test outcomes with sexual assault victims [17]Verified A Study on the Differences of Psychophysiological Response of Sexual Crime Victims by Question Conditions in Polygraph Examination
Confirms that specialized question formats significantly improve polygraph test outcomes with sexual assault victims. Examiners who work with victims in permissible private settings should be aware of these specialized protocols. For guidance on proper polygraph retest procedures, see our comprehensive guide.

The Broader Value of Polygraph in Sex Offense Cases

While victim testing is appropriately restricted, polygraph technology continues to play an important role in sex offender management. Post-Conviction Sex Offender Testing (PCSOT) has been widely adopted — a national survey found that PCSOT was utilized in 79% of adult and 50% of adolescent community sex offender treatment programs across the United States, up from just 29% in 1992 [27]Verified Improving the Quality of Sexual History Disclosure: Emphasis on a Polygraph Examination
Confirms polygraph group disclosed more deviant sexual behaviors and paraphilia interests than comparison groups.

Confirms polygraph doubled the number of risk-related disclosures in UK pilot study comparing 332 vs 303 sex offenders.

In the United Kingdom, a two-year pilot study led by Don Grubin compared 332 sex offenders supervised with polygraph testing to 303 without, finding that the polygraph group made significantly higher numbers of risk-related disclosures — effectively doubling the disclosure rate [29]Verified Mandatory Polygraph Testing for Sexual Offenders (UK Implementation)
Confirms UK government mandated polygraph testing for high-risk sex offenders following pilot study results. These findings led the UK government to mandate polygraph testing for high-risk sex offenders released on license in England and Wales, making PCSOT a statutory license condition. This global adoption of polygraph for sex offender monitoring, explored in our history of polygraph in the UK, demonstrates the profession's continued relevance when applied ethically and in appropriate contexts.

The Remaining States

With approximately half of U.S. states now having explicit polygraph victim protections, the remaining states face growing pressure to align their laws with VAWA requirements and emerging best practices. Utah's experience — where the bill took three sessions to pass despite broad support from prosecutors and police [1]Verified Utah Bans Polygraph Tests for Sexual Assault Victims
Confirms Gov. Cox signed the bill into law in March 2026 after three legislative sessions, and that half of states have similar bans — shows that even in states where the practice is uncommon, codifying the prohibition into law serves important symbolic and practical purposes.

The VAWA funding compliance requirement means that even states without explicit bans must certify that their laws, policies, or practices ensure survivors will not be required to take polygraphs [11]Verified 28 CFR Part 90 — Violence Against Women (STOP Grant Polygraph Prohibition)
Confirms states must meet 42 U.S.C. § 3796gg-8 requirements to prohibit polygraph testing of sexual assault victims for STOP grant eligibility. However, without a state-level statute, enforcement relies on policy and practice rather than law — creating gaps that investigative journalists and advocacy organizations have documented. For those interested in how polygraph regulation has evolved across jurisdictions, our state-by-state timeline of polygraph licensing laws provides comprehensive coverage.

International Perspectives

The United States is not alone in grappling with how polygraph technology intersects with victim rights. In the United Kingdom, polygraph testing of sexual assault victims was never standard practice, though the UK has embraced polygraph testing in sex offender management contexts following the research of Don Grubin and subsequent government evaluations [26]Verified Current Practices and Emerging Trends in Sexual Abuser Management: The Safer Society 2009 North American Survey
Confirms PCSOT was utilized in 79% of adult sex offender treatment programs, up from 29% in 1992. Many European nations have either prohibited or never adopted polygraph testing in victim contexts, viewing such practices as incompatible with victim dignity and due process.

The distinction is clear: polygraph technology has demonstrated significant value in monitoring convicted sex offenders and enhancing public safety [29]Verified Mandatory Polygraph Testing for Sexual Offenders (UK Implementation)
Confirms UK government mandated polygraph testing for high-risk sex offenders following pilot study results, while its application to victims has been consistently shown to be counterproductive and harmful. Utah's law exemplifies this balanced approach, protecting victims while preserving the tool for its most effective and ethical applications.
