LIE DETECTOR TEST (POLYGRAPH TEST) in Delhi/NCR

A lie detector test, scientifically known as a polygraph test, is a tool used to measure physiological responses in an individual while they answer a series of questions. The underlying assumption is that lying is associated with certain physiological changes, and the test aims to detect these changes. Here are some key points to understand about lie detector tests:
Components of the Test:
A typical polygraph machine measures several physiological responses, including changes in
Heart Rate,
Blood Pressure,
Respiration, and
Skin conductivity.
-
Questioning Techniques:
During the test, a trained examiner asks a series of questions, typically categorized into relevant, irrelevant, and control questions.
Relevant questions are directly related to the issue being investigated (e.g., a crime).
Irrelevant questions are unrelated and serve as a baseline.
Control questions are meant to elicit a physiological response in all individuals, allowing for a comparison.
-
Indicators of Deception:
The polygraph measures changes in these physiological indicators, with the assumption that deceptive answers will produce noticeable variations.
-
Accuracy and Controversies:
The accuracy of polygraph tests is a subject of debate. Some studies suggest they can be reasonably accurate, while others question their reliability.
Controversies surround the use of polygraphs, and their results are not always admissible in court.
-
Applications:
Lie detector tests are used in various settings, including
- Relationship And Fidelity Issues
- Pre-employment Tests
- Screening of Employees
- Defence Lawyers
- Detecting Thefts & Stealing in Workplaces / Houses,
- Detecting Financial Frauds, Bungling, Pilferage,
- Spouse infidelity / Character Checks,
- Recruitment Screening,
- Conspiracy by Trusted Persons,
- Identify Addictions / Vices among Children,
- Any other cases where Truth is to be found out
-
Legal and Ethical Considerations:
The use of lie detector tests is subject to legal and ethical considerations, and their use varies by jurisdiction and purpose.
It’s essential to recognize that while polygraph tests can provide insights, they are not infallible, and their results should be interpreted cautiously. Legal and ethical guidelines often govern their use to prevent potential misuse.
