In this context, it became a crucial tool in verifying evidence and ensuring the integrity of judicial proceedings.

The polygraph, commonly known as the lie detector, was invented by John Augustus Larson, a medical student and police officer. Larson built upon the groundbreaking work of William Moulton Marston, who created the systolic blood pressure test. This test ultimately became a vital component of the modern polygraph, alongside other physiological measures.

In today’s society, it has become a valuable tool for various professionals. We often utilize these tests to enhance their services. Process servers across the state have also adopted this technology to improve the accuracy and reliability of their work. The collaboration between Marston’s systolic blood pressure test and Larson’s innovative polygraph has impacted private investigation and process serving.

Professionals often collaborate with certified polygraph examiners to conduct it. These tests can provide valuable information and help reveal deception or verify the truth in investigations.

Passing it is not about achieving a specific score or meeting a set standard. Instead, it’s about the examiner’s interpretation of the physiological responses recorded during the test, which can indicate whether an individual is being truthful or deceptive. No “passing score” or “curve” is involved in the evaluation process. Professionals often rely on this to support their work. The best advice for anyone facing a polygraph test is to maintain honesty and integrity in their actions and communications so they won’t find themselves in a situation where they need to deceive the examiner.

Passing it means demonstrating truthfulness and transparency during Oklahoma and beyond examinations. Individuals can contribute to a more just and transparent society by maintaining a clear conscience and providing accurate information.

He/ She is an individual licensed by the State of Oklahoma to administer polygraph tests on people. The State of Oklahoma licenses him/her to try to determine whether or not someone is lying or telling the truth. Instead of trying to read a person’s emotions, micro-expressions, etc., he/she tries to see whether a person’s breathing rate, pulse, and blood pressure change during questioning. The person is connected to a device that monitors these bodily functions and if changes happen during the questioning process. These tests, also called “polygraph tests, ” can often help provide tremendous insights into whether or not someone is trying to deceive the polygraph examiner when asked specific questions.

A deception expert is a highly skilled individual who is trained at reading an individual’s emotions, expressions, micro-expressions, behaviors, and other deceptive practices. An Oklahoma deception expert knows what to look for in liars. This includes what they say, omit, and so much more. A true professional can usually detect whether or not a person is lying, being deceptive, or telling the truth.

According to the Council on Law Enforcement Education & Training (CLEET), the requirements for licensure as one are as follows:

  • You must be at least twenty-one (21) years of age.
  • The applicant must be a citizen of the United States of America.
  • The applicant must be a person of truthfulness, integrity, and fitness.
  • The applicant must never have been convicted of a felony or misdemeanor involving moral turpitude.
  • The applicant must hold a baccalaureate degree from a college or university accredited by the American Association of Collegiate Registrars and Admissions Officers or, in lieu thereof, be a graduate of an accredited high school and have five (5) consecutive years of active investigative experience or a character satisfactory to the Board.
  • €¢ The candidate must be a graduate of a polygraph examiners course approved by the Board and have satisfactorily completed at least six (6) months of internship training.
  • The candidate must have passed an examination conducted by and to the satisfaction of the Board or under its supervision to determine his competency to obtain a license to practice as an examiner.

The State of Oklahoma does not require a deception expert who does not perform polygraph examinations to be licensed or have specific training. However, many skilled officials have one or more of the following qualifications:

  • They might hold advanced university degrees in related fields.
  • Deception experts might have taken specialized training courses.
  • Some take experience and deception detection training from military and/or law enforcement backgrounds.
  • Many have computer-based training in reading facial expressions and emotions.
  • Some have taken it upon themselves to undergo very intensive self-study.

In addition, some deception experts are referred to as “naturals.” Most of them cannot naturally read people and tell whether or not they are lying or telling the truth without some kind of training in the field. This talent can come so naturally for others that it is almost second nature. Of course, some advanced education in recognizing various emotions, micro-expressions, etc., is almost always extremely beneficial – even to naturals.

He/ She uses a special device connected to the individual in question. After taking a baseline sample to see how a person responds, the licensed official will commence with more content-specific questions. While asking these questions, the polygraph examiner also monitors the subject’s blood pressure, perspiration, breathing rate, pulse, and specific other reactions. If one or more of the subject’s bodily functions fluctuate during the post-baseline questions, it is like he or she is trying to deceive the Oklahoma polygraph examiner.

He/ She is trained to look for clues when the person is both talking and while staying quiet. We prefer not to give away our secrets and what we look for. However, they can certainly discuss the process with you more in-depth as to how they might be able to assist you. Please ask us when you meet with us in person, and the Oklahoma Judicial Process Servers and Private Investigators professionals will be happy to elucidate.

Both can have great success in determining whether or not someone is lying or telling the truth. A licensed polygraph examiner does have to have a consenting individual connected to a special device that monitors his or her breathing rate, blood pressure, pulse, blood pressure, and perspiration. Having a device that can often show interested parties the changes in a person’s bodily functions when someone lies is nice evidence! Given that they are not nearly as focused on human emotions, micro-expressions, etc., as their deception expert counterparts, they do not have to worry as much about misreading someone. Though the old saying, “The body never lies” is quite true, some people are more difficult to read than others.

While they do not necessarily have to focus on reading an individual’s face and other body language, they must still pay close attention to the polygraph examination results, ensuring that they are accurate. They must also watch for behavioral signs of people they evaluate for possible deceptive practices.

A deception expert can also utilize technology when trying to determine whether or not someone is lying. These can range from video cameras to voice stress analyzers and much more. However, they can sometimes catch things that a polygraph examiner needs to look for. Likewise, to determine possible levels of an individual’s deception, using technology or even being in the same room with the person is not always necessary for a deception expert.

He/ She is also ideal when an individual is not available for a polygraph examination. A trained official might only see the person through a video camera or hear his or her voice over a telephone. In these instances, a polygraph examiner would generally find less success in making a determination than a deception expert might be able to do. It goes without saying that they need the person in front of them and connected to a polygraph examination device.

Another instance when they are not as appropriate is when someone becomes easily aroused by outside stimuli. For example, if the licensed Oklahoma polygraph examiner individual is a very voluptuous female and the subject is a heterosexual male, the man’s arousal reactions to the thought of “breasts” could skew the polygraph test results. This holds true of a variety of stimuli, which is why they try to limit the stimuli in the room when giving someone the test.

Whether a polygraph examiner or a deception expert is, the right person for the job is a determination we can help you make. Indeed, sometimes, utilizing the skills of both kinds of professionals can help you achieve the results you most desire. Please contact the professionals at Oklahoma Judicial Process Servers and Private Investigators to see which specialist is right for you!

Polygraph examiners must have the person who is suspected of being deceptive in front of him or her so that the special device can monitor the person’s heart rate, blood pressure, etc. It is not possible for them to evaluate whether or not a person is answering questions in a deceptive manner, without having the individual right there in front of him or her. 

A deception expert dramatically benefits from having the potentially deceptive person before him or her. This way they can evaluate emotions, micro-expressions, and other behaviors. However, it is also possible for them to talk with the individual over the phone or through another device. However, the effectiveness of determining deception is generally increased when the person is present.

Sometimes, someone is such a skilled liar or gives conflicting messages and signals that it may not be possible to determine whether or not they are lying. Our specialists want to help you as accurately and responsibly as possible. We will always do our best to help you in the most legal and ethical way possible.

It is important to note that the field of lie detection is not an exact science. Thus, they can only sometimes tell with one hundred percent (100%) certainty whether or not a person is lying. Some people are incredibly skilled liars and have learned to “beat” lie detector tests. Individuals can even learn how to fake human emotions, and sometimes, they can get their bodies to “play along.” While it can provide great insights and is often very accurate, this field is not a perfect, black-and-white scientific field.

Because this field is not an exact science, many judges usually do not allow the results of these tests as evidence in a courtroom. Whether or not the judicial officials allow their testimony also varies by jurisdiction. Lie detection, whether performed by a deception expert, an Oklahoma polygraph examiner, or both, is not a perfect science. However, an expert can usually detect lies and omissions if performed by a highly skilled individual!

The cost to hire one of our outstanding individuals varies. The length of the questioning, whether or not testimony will be needed, etc. the amount of time spent when making the determination, and other factors will all influence the ultimate cost.
