The Only Way to Beat a Lie Detector Test

 The Only Way to Beat a Lie Detector Test

Although a lie detector (polygraph) is CALLED a test, it isn’t really a test, it is more of an exam. Its role is to try and intimidate a person into telling the truth and making a confession. It is absolutely impossible to ‘detect‘ a lie because there is no lying reaction. As Doug Williams once said in an interview “It is the longest-running con game in the world.

Doug Williams was imprisoned for two years for training a federal agent to use the technique described below and he is also prohibited from giving this information and allowing a person to practice it on his own polygraph instrument. Check this out:

What it actually records is the nervousness of the individual that is being interrogated. Well, what if I told you that you could pass any polygraph in the world? Would you believe me? Well, I’m going to show you how easy it really is because there is a lot of false information out there.

A polygraph records four things which are your:

  • Blood pressure
  • Pulse rate
  • Breathing by means of the straps/tubes around your chest and stomach
  • Sweat activity by means of the electrodes placed on the fingers

As it turns out, the more of a conscience that you have, the more chance you have of failing the so-called test. The polygrapher assumes whether you are telling the truth or lying simply by watching your breathing, blood pressure, pulse rate and sweat reaction changes on the machine. Not at all possible!

Go to any website that teaches you how to spot when somebody is lying and they will say that they start sweating, their breathing changes, and their blood pressure rises. The fact is, these reactions can also be present when you are telling the truth. Embarrassing questions can lead to these very same reactions even when you are being completely honest.

There is a reason that a polygraph can hardly ever be used as evidence in court and that is because the results just can’t be trusted. There is no accuracy in it, much like flipping a coin.


As I mentioned above, as you inhale and exhale the pen moves up and down and for a normal relaxed person, the line that the pen makes will be nice and rounded at the top and the bottom of each wave. When you try to control your breathing, instead of it being even it becomes jagged because you are consciously thinking about it and don’t allow enough time to let the waves round off.

Instead what you should do is:

  1. Slowly breathe in (pen moves up)
  2. Slight pause to allow the wave to round off
  3. Slowly breathe out (pen moves down)

Keep your breathing nice and even and you have perfected the control. Don’t take in more air in one inhalation than the last but try and keep it as even as possible throughout. Practice this until it isn’t obvious that you are trying to control it.

If you look at the image below, it shows the five common pneumo reactions in which you must memorize one or more of them.

Doug Williams: pneumo patterns

If you have already learned to control your breathing then this will come a lot easier than it may look. Again, you don’t want any jagged edges to appear. In figure 3 you are simply breathing normally and then holding your breath for around seven seconds before breathing normally again. So choose a reaction from the 5 in the image above and practice it until you can manipulate the pneumo tracing confidently.

Blood Pressure

For this, all it takes is the tightening and relaxation of the sphincter muscle which is a reaction to things such as fear. The thing is, you don’t need to actually be frightened to tighten this muscle which will increase your blood pressure just like you were. That’s right, act like you are trying to stop a bowel movement and you will notice the cardio tracing pen increases straight away which makes the polygrapher believe that they have a major cardio reaction. Simply put, tighten this muscle to make the pen move up and relax it to make the pen move down.

Sweat Activity

This will be controlled by manipulating both the breathing and blood pressure shown above.

In order to successfully manipulate the chart tracings, you need to get your timing right which is why you must practice as much as possible so that it becomes second nature to you. You need to know when to control a reaction and when to manipulate a reaction. It doesn’t matter whether you are really frightened or just manipulating the reactions, it will show up the same on the polygraph results.

The Questions

During a polygraph there are two types of questions that are asked:

  1. Relevant – has to do with what you are being interrogated for
  2. Control – more general questions that don’t directly pertain to the crime

Now when it comes to the relevant questions, you need to show absolutely no reaction at all while on the control questions you need to show a reaction. This is because they are going to compare your reactions to the sets of questions that were asked. If the reactions are greater on the relevant questions than they are on the control questions then they assume that you are lying, if vice versa then they assume that you are telling the truth. For this reason, you want to give the biggest reaction to the control questions.

When being asked control questions you will be asked questions that they assume you will lie about such as ‘have you ever stolen anything?‘ or ‘have you ever lied to somebody?‘. They may also throw an embarrassing question into the mix so that your reactions can be compared to the relevant responses. Control questions are more general in nature. If you are suspected of stealing £1000 from your brother then a relevant question maybe “did you steal £1000 from your brother” while a control question might be “have you ever stolen any money?

How to Answer the Questions

In order to successfully “pass” the test in regards to the control questions, you need to cause a reaction in both your breathing and blood pressure and when you answer the relevant questions, you need to appear calm and relaxed.

  • Control – think of something that puts fear into you such as falling off a building and hitting the ground
  • Relevant – think of something calm and relaxing such as a nice beach somewhere

Keep concentrating on your responses and do not allow the polygrapher to scare or intimidate you as this is what they rely on. They are nothing more than a fraud and if you can control your reactions then you will pass the test. While it is not important, you can add a nice little finishing touch by looking at the examiner straight in the eyes when you answer all of his questions.

Some examples of questions include:

  1. Is your name _______?
  2. Do you know who stole the money? – Relevant
  3. Have you ever stole anything? – Control
  4. Can you name the person that stole the money? – Relevant
  5. Have you lied to me about any of these questions? – Relevant
  6. Besides what you told me, have you ever stole anything else? – Control
  7. Are you now concealing any information about the case? – Relevant

It is during the first two questions in which you are becoming accustomed to the sound of the polygraphers’ voice that you need to start duplicating your normal breathing. You need to give your largest reaction to question 6 because that is the LEAST incriminating control question so tighten that sphincter and breathe more erratically. Just don’t make it obvious!

If asked which question you remember most of those that were asked, always say the least incriminating control question is the one that you remembered the most so that it appears to be the one that troubled you the most. In no way do you ever mention that any of the relevant questions bothered you.

Make Sure that you Practice

Like anything in else in life, you need to practice as much as possible so that you don’t even need to think about your responses. These examiners are trained to lie and fraudulently lead you into making a confession and they are very good at it so without practice you won’t confidently pass the fraudulent test.

If you want a more in-depth look at beating the polygraph test I recommend reading the book by Doug Williams that inspired this article “How to Sting the Polygraph
