What Is a Polygraph?

A polygraph, often called a lie detector, does not detect lies. Instead, it measures a subject’s physiological reactions to questions. These reactions are then analysed by a trained examiner to determine whether the subject is likely being truthful or deceptive. Think of it like noticing subtle signals in everyday life: avoiding eye contact, shifting posture, or changes in tone can indicate dishonesty. A polygraph works on the principle that lying produces stress, anxiety, or worry, which triggers measurable physical responses.

What Is Involved in a Polygraph Test?

A polygraph test is typically conducted over about two hours at our testing location. A certified examiner will guide you through the process, ensuring a professional and comfortable experience.

Pre-Test Interview:
The examiner will discuss your background, the circumstances of the test, and your feelings toward the process. This helps establish a baseline and builds a profile to interpret physiological responses accurately.

What the Polygraph Measures:

Heart Rate
Blood Pressure
Respiratory Rate
Perspiration

These responses change naturally when someone is stressed or anxious — often the case when attempting deception.

How a Polygraph Machine Works

The examiner attaches sensors to measure your bodily responses:

Cardiograph: Tracks heart rate and blood pressure.
Pneumograph: Measures breathing patterns with chest and belly strain gauges.
Electrodes: Detect changes in skin electrical resistance caused by perspiration.

The test includes baseline questions (simple, factual questions to establish normal responses) and specific questions related to the investigation or concern. Afterward, the examiner analyses the data to provide accurate, professional results.
