A lie detector test is one of the most difficult things to do when undergoing criminal trials or working for certain agencies that value secrecy and clandestine services. Though you may never take one in your lifetime, it is always good to be prepared for it.  

The thought of doing one can be worrying since most people tend to negatively perceive these tests, as projected in movies. About 64% of the 2.5 million people who take these tests annually will likely fail or show some inconsistencies. 

These statistics should not worry you since many ordinary people like you have passed these tests. All it takes is adequate preparation, knowing what to do, and sometimes knowing what to say during the tests.  

Actually, preparation and having all the tips are the first and ultimate steps to passing a polygraph test. Remember, a lie detector is just a tool to gauge truthfulness, so a little preparation should boost your confidence. 

Whether taking it voluntarily or involuntarily as part of an investigation or a job, these steps should help you retain your confidence during the tests.  

1. Do The Trials Before Actual Tests 

If you're ever involved in a case where you must go through the lie detector test, you must be very reliable and knowledgeable about answering the questions. Mock tests may work; however, doing an actual test before the main one can help you notice a few things and familiarize yourself with the experience. 

Such tests can also be reliable when you must do a polygraph test for a job or one related to in-house investigations. So, you can look for reliable lie detector test centers, go through the test, and learn a few things. Actually, they are not expensive and easy to book from the website. After booking, you will get details about the closest location where you can go for the tests. 

You should watch your actions during such trials and mock the tests. If possible, record the whole test since it is not that long; it usually takes minutes. You can watch the video and compare it with the test results to see your reaction, then plan to deal with the issue that makes you vulnerable to failing the main test.

2. Read More About the Process 

You should research the process more and get some video guidelines and details. Remember, not all the guidelines will always work, so you need to be precise about what you're looking for. For instance, if it is a test related to a job, only look for details about passing such tests. Do not mix things up. 

Also, remember that the process is simple, not as complicated as people think, and tends to exaggerate. You can talk to an examiner to learn how the tests work. You can ask your attorney to take you through the process if it is for a lawsuit. 

3. Be Mentally and Physically Ready 

Get good enough sleep to help you be mentally prepared and have enough rest. Avoid alcohol so you can remain fully focused on the exam. Eat enough food but not too much since you must sit through the test without frequent breaks. However, if you need a break, especially if you notice you may get anxious, ask for it.  

4. Be Honest 

As you sit on the main chair with the polygraph machine attached to you, you need to be very honest and truthful. A little lie leads to failure and can give a lawyer or lead to doubts about your answers. So, avoid the little lies, including those embarrassing details you do not want people to know.  

If you do not want to answer some questions, you can tell the examiner you are uncomfortable answering. Avoid excuses to avoid answering specific questions, and do not be too rude if a question is personal.  

While doing the test, the machine aims to detect an inconsistency within your story. This is why you should always tell the truth. If you are unsure what to say, you can ask the person to clarify or ask questions. It does not harm to take a few seconds to think before you answer.

5. Stay Calm 

The lie detector will not catch every lie you tell. It compensates for that shortcoming by detecting changes in your heartbeat, striking temperatures, and blood pressure levels. If you are calm, none of them will spike. However uncomfortable the question is, the graph will remain consistent as long as you are composed.  

So, do not be nervous about anything. Maintain eye contact and be mentally present in the room. If you detect any discomfort, take a few seconds to think before answering. A combination of calm attitude and honesty is the best tool to beat every detector test. You can also ask the examiner to eliminate anything in the room, including colors and objects that may trigger issues, like anxieties related to an incident.

6. Be Precise 

You must answer every question; however, you are not required to provide more details and explanations. So, take advantage of this to answer as briefly as possible, and where necessary, leave it as a yes or a no. Providing more details exposes you to anxiety and some inconsistency in your story. Sometimes, whatever you say may trigger a physiological reaction, especially if you cannot recall correctly. Too many details will lead to inconsistency or a sudden change in body temperature, raising a red flag.  

Final thoughts 

There is a saying that a calm and confident lie can always pass the polygraph. Do not lie; however, you need to be confident and avoid anything that makes you anxious, including a lack of sleep. The briefer details you provide, the better since you are not required to tell long stories. You can seek clarification or take your time before answering anything.
