What Is a Polygraph?

The polygraph machine was first invented by Mr. John A. Larson in 1921 it measures heart rate, blood pressure, and respiration rate to determine whether a person is deceiving the examiners. After many years of scientific research, the polygraph machine was strongly developed through various phases, including the ones made by the famous William Marston. With its features, the polygraph machine can detect slight changes in a person’s physiological characteristics which would then indicate the same or different answer from their verbal response to any question.

However, there were many instances where the lie detector test was carried out illegally to set up another person and admit to any accusations without reasonable cause. Thus, as the government suggests with the approval of the majority, the polygraph testing procedure would only be carried out and done when there is consent from the witness or accused. As of this date, there are many types of polygraph consent forms that are being used around the world to accommodate the different circumstances of undertaking a lie detector test.

To make a polygraph consent form, you can simply browse the Internet and research the scopes of the law under the polygraph testing procedure on witnesses. If you want to make sure that you are doing the right thing, you can refer to the components below as your basis for the document.

1. Title of the Document

It is very essential that you put the title of the document so that your readers would know what they are signing. A simple “Polygraph consent form” would do, but if you want to be specific, you can also put “Parental Consent Form for Polygraph Testing” if the subject is a minor, or “Police Consent Form” if the document is solely for use by police officers of a certain precinct.

2. Details of the Subject

By details, we mean information about the subject and the examiner. This will include the name of the subject, as well as their nationality, age, status, address, and gender. The examiner’s details will include the same details, however, they will also have to state their profession and workplace.

3. Clauses and Conditions

This is the most important section of the document that you should be careful about. It is here where you will set the conditions of the procedure and the scope of work that will be done to you. Also, the clauses and conditions may also include a waiver of liability statement that releases the examiner from any and all responsibility that may arise as a result of partaking in the test.

4. Signatures of Two Parties

With your signatures, both parties affirm that they have understood what is written on the consent form. When in court, a polygraph test without the signature of the examiner and the participant is not admissible and might even be questioned by the prosecution or judge.
