What Questions are Asked on Police Polygraph?
A polygraph examination, also known as a lie detector test, is a tool used by law enforcement agencies to determine whether a person is telling the truth or not. During a police polygraph, a trained examiner will ask a series of questions designed to detect deception. But what kind of questions are asked on a police polygraph?
Types of Questions Asked on a Police Polygraph
There are different types of questions asked on a police polygraph, including:
- Direct Questions: These are questions that directly ask about the specific topic or incident under investigation. For example: "Did you steal the money from the cash register?"
- Control Questions: These are questions designed to determine the test subject’s level of honesty. For example: "Have you ever lied to get out of trouble?"
- Probe Questions: These are questions that ask about specific details related to the incident under investigation. For example: "What was the color of the suspect’s shirt during the robbery?"
Types of Polygraph Questions
Polygraph questions can be categorized into two main types:
- Behavioral Questions: These questions are designed to detect deception by asking about specific behaviors or actions. For example: "Have you ever been in a fight?"
- Event-Specific Questions: These questions are designed to detect deception by asking about specific events or incidents. For example: "Were you at the scene of the crime?"

Here are some examples of polygraph questions that may be asked during a police polygraph:

Common Polygraph Question Categories
Here are some common categories of polygraph questions:
| Category | Examples of Questions |
|---|---|
| General Questions | "Have you ever been in trouble with the law?", "Have you ever broken a rule?" |
| Event-Specific Questions | "Were you at the scene of the crime?", "Did you witness the accident?" |

Important Considerations
It’s important to note that polygraph examinations are not infallible, and a negative result does not necessarily mean that the person being tested is telling the truth. Additionally, a positive result does not necessarily mean that the person is guilty of a crime.
Conclusion
In conclusion, the types of questions asked on a police polygraph are designed to detect deception and uncover the truth. By asking a combination of direct, control, and probe questions, polygraph examiners can gather valuable information to aid in investigations and help law enforcement agencies make informed decisions. While polygraph examinations are not perfect, they can be a valuable tool in the investigative process.
