In recent years, the field of lie detection has faced a significant challenge to its credibility and reputation because of the presence of unqualified polygraph examiners. These individuals, lacking proper training and expertise, have not only compromised the accuracy and effectiveness of lie detection but have also tarnished the overall image of the entire industry. The consequences of their actions extend far beyond individual cases, casting doubt on the reliability of polygraph examinations as a whole. 

In this blog, we’ll talk about how unqualified polygraph examiners gave the lie detector industry a bad reputation.

How Does a Polygraph Instrument Work?

In today’s world, most people are familiar with polygraph tests, often through movies and TV shows. These portrayals typically focus on the charts created by the machine, with lines indicating the subject’s responses. The examiner then interprets the results and determines whether the person is telling the truth or not.

However, it’s important to note that the technology used in modern polygraph testing has evolved. Instead of the traditional moving pen and paper system seen in movies, electronic recording systems are now widely used. These systems collect data electronically, providing more accurate and detailed information for analysis.

Phases of a Lie Detector Test


The pre-test phase involves an initial consultation between the polygraph examiner and the examinee. During this phase, the examiner explains the purpose of the test, establishes rapport, and clarifies any doubts or concerns. Relevant questions are discussed, and the examinee’s physiological baseline is established through non-intrusive measurements.

Data Collection

While answering a series of predetermined questions, the examiner monitors and collects the physiological data of the examinee, capturing any changes that may indicate deception or truthfulness.


In the analysis phase, the collected data is meticulously examined and interpreted by the polygraph examiner. Based on these analyses, the examiner forms an expert opinion regarding the truthfulness of the examinee’s responses.

What to Look for When Choosing a Lie Detector Test

When choosing a lie detector service, whether it’s for yourself or someone close to you, the stakes can be high. You want to ensure that the examiner and their equipment are of utmost quality to obtain the most accurate results. 

Verifying the truth or detecting deception can have significant implications, such as resolving conflicts, making informed decisions, or protecting one’s reputation. Therefore, it is important to select a reputable and skilled examiner, equipped with reliable and advanced technology, to maximize the chances of obtaining reliable and meaningful outcomes from the lie detector test.

Beware of Unqualified Polygraph Examiners

Before hiring a polygraph service, ensure to check the qualifications and expertise of the examiner, as well as their utilization of the latest technology. Additionally, consider if they are members of any reputable organizations in the field.
