Infidelity Polygraph Tests

A polygraph test is a tool used to measure physical responses like heart rate, breathing, and sweating to determine if someone is being truthful. ​

The test has four main parts:

1. Pre-Test Interview: This is a conversation between the polygraph examiner and the person taking the test. It helps explain the process, the equipment used, and the types of questions that will be asked.

2. The Examination: This is where the actual test takes place. 

3. Data Analysis: After the test, the data is saved and stored on a computerized polygraph system, where it is analyzed and scored by comparing answers to relevant and control questions to assess truthfulness.

​

The possible results are:

​

• Pass: The individual’s responses indicate they are truthful.

• Fail: The individual’s responses suggest deception.

• Inconclusive: The results are unclear, and no definitive conclusion can be drawn.

• Unable to Test: Factors such as physical conditions or technical issues prevent a proper test.

How Does a Polygraph Test Work?

​

A polygraph measures various physiological responses, including heart rate, breathing patterns, sweating, and eye movement, when specific questions are asked. 

​

One of the key aspects monitored is pupil dilation, which can indicate emotional or physiological stress, potentially suggesting deception. Eye movement is also observed, as it can provide additional insight into a person’s cognitive or emotional state. 

​

Can Someone Fool a Polygraph?

​

Some people try to cheat on the polygraph, but experienced examiners and computerized polygraph scoring software are familiar with these countermeasures.

If someone tries to deceive the test, it’s often detected, and they will be removed from the test and fail the exam. The goal is to answer questions truthfully, not to manipulate the results.

​

What Happens if Someone Refuses the Test?

​

It’s important to recognize that forcing someone to take a polygraph when they are not emotionally or mentally ready can be harmful.

In some cases, if the person is experiencing extreme anxiety, trauma, or stress, taking a polygraph may not be appropriate. 

​

It’s crucial to assess whether the individual is in a healthy place to engage in the process. While a refusal could raise concerns, it should not be viewed as a definitive indication of dishonesty. 

​

Instead, it could be a signal that the person is struggling with deeper emotional issues that need to be addressed first. 

​

Can the Spouse Be Present During the Test?

​

Ethical guidelines prevent anyone from being in the room during the test except the polygraph examiner and the person taking the test.

However, the spouse can be involved in the process before the scheduled appointment. This ensures that the test remains fair and unbiased.

Important Reminder About Polygraphs

​

A polygraph is not a form of punishment; it is a tool designed to help rebuild trust and safety in relationships.

While it can provide valuable insights, it is not infallible and should not be treated as an absolute truth. It’s just one piece of the puzzle, and it should always be used alongside empathy, compassion, and open communication for healthier relationships.

​

If you choose to take a polygraph, understand that it is one step in the process.  The results of a polygraph test should never be seen as the sole reason to end a marriage or relationship.

Rather, they should be viewed as an opportunity for growth and healing, fostering honesty and trust.
