What is the purpose of the pre-testing interview before a polygraph examination?

The pre-testing interview before a polygraph examination serves multiple essential purposes that encompass various aspects of the examination process. One of the primary goals is to help the subject relax, which can lead to more accurate results during the polygraph test. A relaxed subject is less likely to exhibit heightened physiological responses that may confuse the interpretation of the results.

Additionally, this interview allows the examiner to establish rapport with the subject. This interaction is crucial for fostering trust and open communication, which can result in more honest responses. Understanding the subject’s background, concerns, and any emotional states can aid the examiner in preparing for the examination and addressing any misconceptions related to the process.

Moreover, while the primary focus of the polygraph is not to judge character, the pre-testing interview does enable the examiner to gain insights into the subject's demeanor and psychological state, which can be relevant for overall interpretation of the results.

By encompassing all these elements—relaxation, rapport-building, and gaining insights into the subject—the pre-testing interview is a vital step in the polygraph process, making it clear why selecting an option that acknowledges all aspects is correct.
