When someone wants to investigate something, they might prefer polygraph examiners and polygraphists. However, there are some instances where the most experienced experts cannot execute polygraphs or lie detector tests on people. Here are 7 such situations in this blog post which are shared by professionals including private investigators in Oklahoma City.
● Medical conditions
Polygraph examiners mostly avoid testing individuals with health issues that can interfere with the precision of the tests. For example, people who have heart problems, respiratory problems, or hypertension may show physiological responses. Those responses can mimic the results with false positives. Private investigators in Oklahoma City will not proceed on such polygraphs as they prioritize the safety and health of their clients.
● Mental illness
People with mental illness such as PTSD, anxiety disorders, bipolar disorder can also cause obstacles for polygraph examiners. These conditions can cause confusing physiological responses that are not easily interpretable. These responses make it very tricky to provide accurate results. Investigators near me suggest substitute ways to gather information in such cases.
● Substance influence
The physiological responses become unreliable if the person is under the influence of alcohol or drugs. It makes the results inaccurate. Polygraphists will not conduct tests of people who were admitted to recent substance use or look visibly intoxicated. Private investigators in OKC emphasize the importance of abstinence during the polygraphs to ensure best results.
● Extreme exhaustion
Fatigue can impact an individual’s physiological responses while conducting a polygraph test. If a person is awake for a long time or hasn’t slept properly, their body may produce unreliable reactions that can affect the accuration of results. Polygraph examiners ensure the person is active and relaxed before the test.
● Language barriers
For a successful polygraph examination, effective communication is really important. If the examiner and the subject can’t understand each others’ language, misunderstandings can lead to inaccurate results. Polygraph examiners may suggest alternative methods of investigations or use of a qualified interpreter for such cases.
● Intellectual debility
During the polygraph examination, individuals with intellectual disabilities may find it difficult to understand the questions. It can cause inconsistent responses and confusion. Polygraph examiners make sure that the individual comprehends the process completely. If the subject is not aware of the procedure, the examiner may refuse to conduct the test.
● Lack of agreement
It is essential that the individual is fully agreed for the process before the test. If the individual doesn’t approve the process or withdraws at any point, the polygraphist should terminate the test immediately. Private investigators in Oklahoma City emphasize the well-being and rights of the individuals and never force anyone to endure a test.
While polygraph experts can be helpful for uncovering the truth, it is important to know the limitations. By understanding the situations where polygraphic tests are not recommended, private investigators in OKC can ensure most accurate results for their clients. If there’s an issue, it is advised to talk to a professional who can guide you about the appropriate way of investigation for every unique situation.
