Many people become anxious when hearing about lie detection tests. They consider such tests to be massive, powerful machines that can determine whether someone is lying or telling the truth. The source of this anxiety is limited knowledge of these tests.
This article explains what a lie detector test is, followed by simple tips to pass it. Remember that “pass” doesn’t mean fooling the machine or tricking the examiner. It implies giving truthful answers calmly as well as confidently to ensure that test results reflect the truth accurately.
How to Pass a Lie Detector Test?
A lie detection test (or polygraph test) is a process that measures a person’s body’s reactions when they answer questions. The reactions may include:
Heart rate
Blood pressure
Breathing pattern
Skin sweating
The test is based on this idea:
The person’s body reacts in certain ways when they lie or feel stress or fear.
It is important to prepare for the test because such states of mind can affect the results even when a person is telling the truth.
Nervousness
Fear
Confusion
Stress
That said, let’s walk you through the guide to prepare for the lie detection test.

1) Always tell the truth
What’s the most effective way to pass the lie detection test? By telling the truth.
This is what happens when you speak the truth during the test.
Your answers remain consistent.
Your brain does not need to remember fake details.
Your stress level is lower.
When you lie, you have to:
Create a false story.
Remember what you said earlier.
Deal with the fear of getting caught.
All these actions lead to stress. A lie detection machine can detect stress easily.

2) Understand how the test works
Fear comes from a lack of knowledge. Some people believe that a lie detection machine can read minds. This is a false idea.
This test measures the body’s reactions when the examiner asks the following types of questions.
Relevant questions. Directly related to the issue.
Control questions. General questions, like “Have you ever lied?”
Neutral questions. Simple facts like your name or age.
The person’s body may react in certain ways during the interrogation. The reactions will expose truth and lies.
Before the test:
The examiner simply explains the process.
You will comprehend what sorts of questions will be asked.
You may be asked simple “yes” or “no” questions.

3) Stay calm as well as relaxed
Even honest people can feel nervous during a lie detector test.
Here is how to beat nervousness:
Focus on slow, deep breathing.
Sit still.
Make sure you are comfortable.
Listen carefully to each question.
Don’t overthink.
Don’t assume that the machine will think you are lying. This thought itself can increase stress levels.

4) Listen carefully and only answer what is asked
Listen to what the examiner asks. And then, answer in “Yes” or “No”. Don’t overexplain.
If the examiner asks:
“Did you take the money?”
Wrong approach:
“No. But I was there. And I saw it. And I thought about it.”
Correct one:
“No.”

5) Be honest during the pre-test interview
There is a pre-test interview before the actual test.
This is what happens during the pre-test interview.
The examiner explains the questions.
You are asked about your background.
You can clarify misunderstandings.
You can share your medical history as well as anything that can impact the test results.
Tip: Do not hide any information from the examiner in the pre-test interview. It will always come up later.

Winding Up
A lie detection test can seem scary. Truth tellers who know how to calm down their anxiety can pass the test. That too effortlessly!
Give your body a light, healthy meal before the test.
