Q: What is a polygraph test?

A: A polygraph test, also known as a lie detector test, is an examination that measures and records various physiological responses of an individual while they answer a series of questions. It is used to assess truthfulness or deception based on changes in heart rate, blood pressure, respiration, and skin conductivity.

Q: How does a polygraph test work?

A: During a polygraph test, sensors are attached to the examinee's body to monitor physiological responses. The examinee is asked a series of questions, including control questions and relevant questions related to the specific issue being investigated. The polygraphist interprets the recorded responses and determines whether there are indications of deception.

Q: Are polygraph tests reliable?

A: While polygraph tests provide valuable insights, it's important to note that they are not infallible. The accuracy and reliability of polygraph results depend on various factors, including the skill and experience of the polygraphist, the quality of the equipment used, and the individual's physiological and psychological factors. Polygraph results are typically considered as part of a larger investigative process. It is important that the polygraph examiner be a member of an accredited polygraph organization.

Q: Is the information obtained during a polygraph test confidential?

A: Yes, confidentiality is a crucial aspect of polygraph testing. Polygraphists adhere to strict ethical standards and guidelines to protect the privacy and confidentiality of individuals being examined. The information obtained during a polygraph test is treated as confidential.

Q: How long does a polygraph test take?

A: The duration of a polygraph test can vary depending on the complexity of the issues being investigated. Generally, a polygraph examination can last anywhere from one to three hours (with a maximum of 4 hours).

Q: Can medications or medical conditions affect the results of a polygraph test?

A: Yes, certain medications or medical conditions can potentially impact the physiological responses measured during a polygraph test. It is essential to inform the polygraphist about any relevant medical conditions, medications, or substances that might affect the test. This information will be taken into consideration during the examination process.

Q: Are there restrictions on who can take a test?

A: People under the age of 16 years old and women who are pregnant cannot be tested.
