What does it mean to “fail” a lie detector, or polygraph, test? The implications of such a scenario are often misunderstood. Unlike a school examination, a polygraph doesn’t measure knowledge or intelligence but rather physiological responses that may indicate deception. If you’re telling the truth, passing a lie detector test should be straightforward.
The Role of the Autonomic Nervous System (ANS)
Lie detector technology operates by monitoring changes in the body, specifically within the Autonomic Nervous System (ANS). The ANS regulates bodily functions such as respiration, heart rate, blood pressure, and perspiration – functions that continue whether you’re consciously aware of them or not.
During a polygraph examination, the ANS’s defensive responses to specific questions or statements can indicate dishonesty. If the polygraph examiner concludes that there’s a pattern of deceptive responses to several questions, it is interpreted as a “fail”.
The “Deception Indicated” Verdict
A “deception indicated” verdict from a lie detector test doesn’t always mean that an individual has lied outright. However, extensive research and test results suggest that 90 to 95 percent of individuals who show such a response have either lied or withheld pertinent information, a phenomenon known as guilty knowledge.
Lie detector tests are employed in the United Kingdom for various purposes, including:
– Screening potential candidates in recruitment processes
– Assisting individuals falsely accused of an act
– Helping authorities verify the credibility of witnesses or suspects
– Monitoring criminal offenders on parole
– Verifying fidelity in relationships
– Investigating suspected fraud or theft within businesses
Failing a lie detector test due to withheld information can often mean that the subject has concealed something significant relating to the questions asked. Withholding information, especially if it might incriminate the individual, often leads the examiner to view the subject as a potential suspect. If law enforcement is involved and you “fail” a lie detector test due to withheld information, it is likely to prompt more thorough investigations.
The Next Steps After “Failing” a Lie Detector Test
The outcomes of a lie detector test are not always conclusive or legally binding. In fact, their use is controversial due to questions about their accuracy, and their results are not admissible as evidence in many jurisdictions.
However, if you “fail” a lie detector test, you should consider the potential reasons why. If it’s because you withheld information, it’s worth contemplating the reasons behind it. It’s always advisable to be completely transparent during a polygraph test to avoid misinterpretation of the results.
Remember, the aim of the test is to facilitate truth-telling. If you believe you’ve been misunderstood, it’s essential to voice your concerns to the examiner or consider a retest with a different examiner. A thorough explanation of your responses may assist in clearing up any misunderstandings, emphasizing the importance of open communication throughout the process.
In conclusion, a “fail” in a lie detector test does not necessarily equate to guilt, but it may indicate that further discussion or investigation is required. It’s crucial to approach these tests with honesty and clarity, keeping in mind the role of the ANS and the nature of the examination itself.
