What Is Asked on a Police Polygraph Test?

In today’s world, law enforcement agencies rely on various tools and techniques to ensure the integrity and reliability of their workforce. One such tool is the polygraph test, commonly known as a lie detector test. Police departments often use this test during the hiring process to assess the truthfulness and credibility of potential candidates. But what exactly is asked on a police polygraph test? Let’s dive deep into the world of polygraph examinations and explore the questions commonly asked during these tests.

A polygraph examination is a process that measures various physiological responses of an individual while they are asked a series of questions. These responses include changes in blood pressure, heart rate, respiration, and perspiration levels. The polygraph examiner analyzes these responses to determine if the person is being truthful or deceptive.

During a police polygraph test, the examiner will typically ask a combination of relevant and irrelevant questions. Relevant questions are directly related to the specific incident or crime being investigated, while irrelevant questions serve as a baseline to measure the person’s physiological responses. The primary purpose of asking irrelevant questions is to establish a comparison point against which the relevant questions can be evaluated.

The relevant questions in a police polygraph test are designed to elicit a strong emotional response from someone who is guilty, while an innocent person would typically respond with a lesser emotional reaction. These questions often revolve around the alleged crime, such as “Did you steal the missing money from the evidence locker?” or “Were you involved in the assault that occurred last week?”

In addition to relevant and irrelevant questions, a polygraph test may also include control questions. Control questions are designed to create anxiety in both innocent and guilty individuals. These questions are not directly related to the incident being investigated but are meant to gauge the examinee’s physiological responses under stress. For example, a control question could be “Have you ever lied to someone you cared about?”
