Lie detector tests, also known as polygraph tests, are controversial and their accuracy is often debated. These tests measure physiological responses like heart rate, blood pressure, respiration, and skin conductivity while a person is asked specific questions.
Narcissists are known for their manipulative and deceptive behavior. While it is possible that a narcissist may pass a lie detector test due to their ability to remain calm and composed even when lying, it's also possible that they could fail it if their physiological responses give away their deception. Ultimately, the accuracy of the test and the individual's ability to manipulate their physiological responses can vary.
In a divorce case, lie detector test results may or may not be admissible as evidence, depending on the laws and regulations of the jurisdiction where the divorce is taking place. Even where they are admissible, they might not carry substantial weight as the sole evidence in court.
If you suspect that your spouse is a narcissist and you're dealing with a difficult divorce situation, it's essential to consult with a qualified attorney who can advise you on the best course of action. Legal professionals can help you gather relevant evidence, protect your rights, and navigate the complexities of the divorce process.
