Lie detector tests assess physiological reactions to questions, such as heart rate, blood pressure, respiration, and perspiration. Studying these responses allows a polygraphist to determine whether a person is lying under questioning. But innocent people sometimes fail lie detector tests because of fear, stress, or health problems. When a lie detector test is wrong, it can ruin lives, expose a family, and gridlock a police investigation. Lie Detector Experts Reveal Six of the Most Ridiculous Lie Detector False Positives Ever to tell stories of the failed lie detector tests and their consequences. And Oklahoma City private investigators use this information to develop better testing protocols.
Price of Lie Detectors’ False Positives
A lie detector false positive is when charts indicate deception. Polygraph testing only measures stress. So, anxiety, stress, and antidepressant medications can look like lies on polygraph recordings. An innocent person’s responses can be more pronounced than those of a liar. And if the examiner isn’t well-trained, he/she may interpret normal fear to be lying. Experienced OKC investigators know these and use the results as an investigative tool, but not a definitive ruling. Moreover, private investigators near me incorporate polygraph, evidence, and testimonies.
Case One: Paranoid Applicant for a Government Job
A man applied for a high-security government job with a clean background. The applicant had extreme physiological responses to questions about drug use and theft. The polygraphist deemed these to be signs of lying, and the applicant lost the position. But subsequent analyses revealed no signs of deceptive behavior. The applicant was extremely anxious during all essential questions. And fear of losing the job produced greater responses than feelings of guilt. Polygraphists now take extra care to soothe and explain processes prior to sensitive work selections.
Case Two: Widow under investigation
Police interrogated the widow of a suspicious death. Her responses to questions about the death were highly negative on the polygraph. Police took these to be signs of guilt. And, they had a sole focus on her for months. But their investigation later found a different suspect. She showed genuine fear at her predicament and grief, not guilt. Oklahoma City private detectives now advise caution when conducting polygraph exams of people who have recently suffered trauma, such as the loss of a loved one.
Case Three: Silenced by Prosecutors’ Charts
An employee at a company claimed financially damaging offenses and agreed to take a polygraph. The charts showed heightened arousal to questions about motives and truthfulness. The boss questioned the employee’s testimony based on the liar report. But an audit later found each of the whistleblower’s allegations to be accurate. Their levels of anxiety and panic attacks skewed the results. And this case prompted polygraph operators to make sure employment candidates aren’t dealing with any mental health issues before they take the test. Corporate process servers in the United States, such as in Oklahoma, now encounter these types of cases.
Case Four: Cross‑Cultural Language Barrier
An intercultural employee failed a corporate polygraph test. The examiner interpreted respectful pauses, lack of eye contact, and stiff posture as being deceptive. These behaviors aligned with the employee’s cultural norms relating to authoritative relationships. The polygraph showed a continuous state of stress. The real criminal later came forward, absolving the unfortunate employee. Private investigators in Edmond, OK, and private investigators in Norman, OK, are now taught about cultural differences in communication. In addition, ethical examiners are aware of cultural differences and their significance.
Case Five: The Drugged Subject with a Secret
A subject regularly took upper respiratory stimulants and an anxiety reducer prior to scheduling a polygraph. The drugs caused irregular respiratory and heart rate. Finally, he had a heart condition that further impacted all physiological measurements. The examiner detected deception when the subject was asked about stealing and embezzlement of funds. They terminated the worker because of the polygraph. Subsequent medical review attributed all the irregularities in the record to medications and medical issues. Process servers in Edmond, OK, now have an investigator on their team who notes these issues before the test, and tests may not be scheduled.
Case Six: The Bad Test that Led to a False Confession
The worst case is of a violent crime suspect who voluntarily took a polygraph. The results showed large reactions for each question about the crime. This allowed the police to interrogate the suspect for hours. And they continued insistently to claim that the charts showed indisputable guilt. Being grilled relentlessly, the suspect eventually simply confessed. But years later, the suspect was exonerated by DNA evidence, and the perpetrator was found. Six of the Biggest Lie Detector False Positive Fails of All Time (from polygraph experts), partly because this case demonstrates how false positives lead to false confessions. Also, police near me now train officers not to use polygraph test results as hints, clues, and suggestions.
