Many people wonder how to pass a lie detector test. The best way is to be honest with all the questions and remain calm throughout the exam.
Invented nearly a century ago by William Moulton Marston, the polygraph monitors changes in blood pressure, heartbeat, respiration and perspiration to detect physiological reactions associated with lying. Some famous guilty criminals like Green River Killer Gary Ridgway and Russian mole Aldrich Ames have used so-called countermeasures to beat polygraph tests.
Breathing
Breathing is a subconscious process that takes place in your lungs and diaphragm. It should be effortless, steady and relaxed at all times. If it isn’t, you are likely taking shallow breaths, which can increase your heart rate and make the machine detect a lie.
Lying usually causes a person’s heart rate to increase, their blood pressure to rise and they begin to drip sweat. Polygraph machines, also known as lie detector tests, detect these physiological responses and are able to distinguish between the truth and lies.
To pass a lie detector test, you should practice deep breathing and relaxation techniques. It is also important to avoid caffeine and alcohol before the test. You should also stay calm and answer all of the questions truthfully. If you don’t, the examiner will consider your answers as suspicious and you may fail the test. The examiner will ask you a series of control questions and relevant questions about the incident that you are being tested for.
Listening
In addition to breathing, it’s important to listen properly during a polygraph test. The examiner may ask you to repeat back his questions, so that he has a record of your answers. If you’re not listening carefully, the examiner may think you’re lying and give you a negative result.For more info I’ll suggest you visit the website Lie Detector Test.
There are a variety of ways to beat a lie detector test, but most don’t work. Spontaneous countermeasures like being upset or nervous throughout the test can skew results. Likewise, biting your tongue or putting a tack in your shoe to use pain to affect perspiration levels don’t work because the machine is measuring your body’s reaction to stress and not the difference between truthful and dishonest answers.
Some people use mental countermeasures such as daydreaming or imagining calming scenes to control their physiological responses during the test. Others try to manipulate the examiner by using a different voice or changing the frequency and pitch of their voice during the tests.
Answering Questions
Despite what you may have seen on TV, modern polygraph machines are not infallible. If you do the proper preparation, you should be able to give truthful answers and pass the test.
During the test, you will answer a series of control questions and then comparison questions that are designed to elicit your physiological responses. You will only fail if the spike in your responses to the question that is relevant to the case or situation is significantly larger than the spikes you create during the control questions.
Some people have tried to cheat the test by trying to alter their body’s responses by drinking alcohol or taking drugs that can be detected on a breathalyzer or urine test. However, this can backfire, because the examiner will know that you are trying to trick the machine and can judge your results more harshly once the test is complete. Other people have attempted to use mental countermeasures like daydreaming or imagining calming scenes to reduce their physiological reactions.
Countermeasures
Many people search the internet for ways to “beat a lie detector test.” However, most of these tips won’t work. For example, biting your tongue can cause pain and alter stress responses that the machine is measuring. The same goes for putting a tack, nail or piece of broken glass inside your shoe to affect your blood pressure and perspiration rates. These methods can also tip off investigators to your attempts to manipulate your results.
Another way to cheat a polygraph is to daydream about something relaxing. This can calm your physiological responses and mask a lie from the truth. Unfortunately, the examiner will know that you’re trying to manipulate your results and may judge your answers more harshly once the test is over.
