Crafting Powerful Polygraph Inquiries: A Detailed Handbook
Polygraph exams, often referred to as lie detectors, are complex and nuanced tools used to investigate significant issues. When used correctly, they can provide valuable insights. Here's a guide to designing effective polygraph questions based on key guidelines.
**Effective Polygraph Questions: The Basics**
1. **Question Types**: Polygraph questions can be divided into three main categories: control questions, relevant questions, and comparison questions. Control questions establish a baseline physiological response, relevant questions are specific to the issue being investigated, and comparison questions help compare responses between relevant and control questions.
2. **Question Structure**: Questions should be clear, concise, specific, and avoid ambiguity. They should focus on specific behaviors or actions rather than general attitudes or beliefs.
3. **Question Sequence**: Questions should follow a logical sequence, often starting with control questions to establish a baseline. They should be spaced to allow physiological responses from previous questions to dissipate, typically between 20 to 25 seconds apart.
4. **Question Format**: Questions should be framed to elicit a simple "yes" or "no" answer to reduce ambiguity. Standardized formats like the UTAH test (one question) or the AF/MGQT (three question) format are recommended to ensure accuracy and reliability.
5. **Examinee Preparation**: Examinees should understand the testing process and be encouraged to ask questions if unclear. They should be well-rested and avoid stimulants before the test to ensure accurate results.
**Choosing the Right Type of Exam**
Polygraph exams can be categorized into several types, including Single Issue Exam, Multi-Facet Exam, Multiple Issue Exam, Screening Exam, and Statement Verification Exam. Each type serves a unique purpose and is chosen based on the circumstances of the case.
For instance, the Single Issue Exam is the most accurate and scientifically validated format for legal proceedings, while the Screening Exam is used to scrutinize various aspects of an individual's past and behavior, from criminal activities to job performance.
It's important to note that hypothetical questions about future intentions or hypothetical situations are not permissible, and questions must have a factual basis. Appropriate terminology should be used, avoiding legal jargon or inflammatory language.
**Maximizing Accuracy and Reliability**
By following established rules and choosing the appropriate type of exam, the accuracy and reliability of the results can be maximized. No overlapping questions should be asked in a polygraph exam, and questions should be clear, unambiguous, concise, and specific. They should directly relate to what the examinee has disclosed to the examiner.
In a Multi-Facet Exam, questions should be related to ensure accuracy. Clients are encouraged to outline the primary issues they wish to address, and collaboration between the client and the examiner is crucial when preparing for a polygraph exam.
Polygraph exams are designed to address key issues rather than numerous detailed questions. Despite their limitations, when used correctly, they can provide valuable insights into significant issues. However, it's important to remember that polygraph results are not admissible in court in many jurisdictions due to concerns about their accuracy and reliability.
