Polygraph testing is an examination of a person’s truthfulness with a measure of science. This is accomplished by measuring physiological reactions by the person taking the test while answering a series of questions. The person taking the test first needs to fill out an information form that includes a pre-test interview. They will then take the polygraph exam with up to twenty questions which are asked one after another and answered with yes or no responses. These tests can be used for various cases such as criminal cases, background checks, law enforcement work, immigration cases, and more.
Who Does A Polygraph Test In NYC?
The polygraph test can be performed by a certified technician or person trained to use a Polygraph machine. They must take the pre-test interview so that they know about any medical conditions, medications, and other things that may affect the results of the test. The entire process of this exam is different based on if you are taking it for employment purposes or if there has been some sort of crime committed.
How long do these tests last?
It depends on how many questions are asked and also how comfortable you are with taking the polygraph test since this could play a role in your heart rate as well as other things. When being taken for a job, someone usually takes around 20 questions under 5-8 minutes while one done by law enforcement officers is longer with around 80 questions, at least forty minutes in length.

How Accurate IS Polygraph TestING
Polygraph tests are not perfect. There have been many cases where an innocent person is taken for a guilty one due to given false information and also false test results.
The accuracy of the polygraph depends on how many questions you’re asked. When less time is dedicated to taking the test, it will not be as accurate as when time is allotted for the person being examined to recover from each question before moving on to another one. The more intense the subject matter, emotional reaction, or length of details given in facts towards a crime that has been committed; this can increase the heart rate or activity which could complicate the reading results in some cases too. As you can see, these tests aren’t exact science, but they do provide some guarantee that there’s a real chance of seeing some truthful reactions during the test.
Are Polygraph Tests Admissible in Court?
Polygraph tests are in many cases not admissible in court. Investigators often use this method to make a preliminary determination as to how truthful someone is. If it shows that they have lied or has an inconclusive result, then this will not help prove innocence in your regard. Many people believe that polygraph exams are foolproof, but nothing’s perfect when it comes to science and technology. However, these machines still provide law enforcement with useful information which can be used against you as well as for you if you were innocent or guilty of something based on given results at the time. You can always ask for a dismissal of charges based on a voluntary test. There is, however, no guarantee that it would be granted.
