Introduction:
The polygraph, often called a "lie detector," is a tool sometimes used in law enforcement investigations, including during the screening process for police officer applicants. While its admissibility in court is often debated, polygraph tests remain a significant part of the background check for many police departments. This article delves into the types of questions typically asked during a police officer polygraph examination, explaining the process and its limitations. Understanding the nature of these questions can help aspiring officers prepare and navigate this crucial part of the recruitment process.
Understanding the Polygraph Process for Police Officer Candidates
A polygraph test measures physiological responses – heart rate, blood pressure, respiration, and perspiration – while the subject answers questions. The examiner interprets these changes to assess truthfulness. The process typically involves three types of questions:
-
Control Questions: These are designed to elicit a measurable physiological response from anyone, regardless of truthfulness. Examples include questions about past minor infractions or embarrassing moments. The purpose is to establish a baseline of physiological responses.
-
Relevant Questions: These are the central questions pertaining to the specific investigation, in this case, concerning an applicant's honesty, integrity, or suitability for police work. Examples might include questions about past drug use, involvement in criminal activity, or instances of dishonesty.
-
Irrelevant Questions: These are neutral questions unrelated to the investigation, used to establish a baseline and identify unusual responses. Examples include simple questions about the subject's age, address, or current job.
Types of Relevant Questions for Police Officer Applicants:
The specific questions asked will vary depending on the department and the information already gathered during the background check. However, some common categories include:
1. Criminal History & Behavior:
- Have you ever committed a crime, even a minor offense, that you have not disclosed?
- Have you ever used illegal drugs, even if it was only one time?
- Have you ever been involved in a physical altercation where you used excessive force?
- Have you ever lied to a police officer or other authority figure?
- Have you ever stolen anything, no matter how small?
2. Honesty and Integrity:
- Have you ever cheated on a test or exam?
- Have you ever falsified information on any application or document?
- Have you ever violated any rules or regulations?
- Have you ever taken something that didn't belong to you?
- Have you ever engaged in any behavior that could compromise your position as a police officer?
3. Character and Mental Fitness:
- Have you ever been diagnosed with a mental health condition? (This will often be followed up with specific clarifying questions.)
- Have you ever experienced significant emotional distress or trauma?
- Have you ever attempted suicide or self-harm?
- Have you ever had problems with alcohol or substance abuse?
- Have you ever engaged in any behavior that could be considered violent or aggressive?
4. Financial Responsibility:
- Have you ever declared bankruptcy?
- Have you ever had any significant financial issues or debts?
- Have you ever been involved in any financial impropriety?
Important Note: The questions are carefully worded to avoid ambiguity and to focus on specific behaviors rather than general character traits. Examiners are trained to detect evasiveness and attempts to deceive.
Limitations of Polygraph Tests for Police Officer Screening:
It's crucial to understand the limitations of polygraph testing. While the technology can detect physiological changes, it cannot definitively determine truthfulness. Factors such as anxiety, nervousness, and other physiological conditions can affect the results. Furthermore, experienced individuals can sometimes manipulate their responses to influence the outcome.
Countermeasures: Some individuals employ countermeasures, techniques designed to influence the results. This can involve controlling breathing, mentally focusing on distracting thoughts, or even physically manipulating their physiological responses. While sophisticated polygraph techniques aim to detect such countermeasures, they are not foolproof.
Preparing for a Police Officer Polygraph Test:
While you can't "beat" a polygraph, honest and thorough preparation can improve your experience.
- Review the application materials carefully: Make sure you understand the expectations and requirements. Thorough preparation will reduce anxiety during the test.
- Be honest with yourself: If you have concerns or uncertainties, address them proactively before the test.
- Obtain legal advice: Consult with an attorney if you have concerns or questions regarding the process. They can advise you on your rights.
- Be calm and composed: A relaxed approach is more conducive to achieving accurate results.
Conclusion:
The use of polygraph tests in police officer screening is a complex issue. While they provide one piece of information in the comprehensive background investigation, their limitations must be recognized. Understanding the types of questions asked and the process itself can help applicants approach the examination with confidence and transparency. Remember that the goal is to demonstrate honesty and suitability for the role of a police officer. Open communication with the testing authority and legal counsel, if needed, is paramount throughout the process.
