What is a Polygraph Examination?

A polygraph examination is widely known as a lie detector test. The test gets done using a device that records bodily responses such as respiration, heart rate, blood pressure, and perspiration. All these results get used to determine whether the person is telling the truth or not.

The purpose of a polygraph examination is determined by where it gets used by measuring physiological responses. For example, it is used in ‘security screening’ to identify those individuals who pose a threat to national security.

Types of Polygraph Examinations

Counterintelligence. Counterintelligence is where the individual may get asked questions such as espionage, terrorist activity, or sabotage. It came out as a design to filter out traitors who are in contact with foreign agencies and are at risk of compromising sensitive information.


Lifestyle is where personal questions are asked; regarding illegal drug activity or manipulation of clearance forms. It gets an aim at finding out the exact details of misfortunate happenings.

How a Polygraph examination gets handled

When applying for a government position, it is mandatory to undergo a polygraph examination; however, it depends on the industry itself for private industry positions.

There is a tester who administers the exam. The room where the exam gets handled is where only the subject and tester are present.

The tester then proceeds to ask a series of yes/no questions as a polygraph screening. While the subject answers, data gets collected via the physiological changes that the subject outputs.

There is also an operator which analyzes the data and then determines whether the subject is lying or not. However, since many operators choose the lies by changes such as increased perspiration or pulse, the tests sometimes prove inaccurate.

It is advisable for individuals suffering from an illness or pregnant women not to take the test.

  1. Don’t Explain

Even if the examiner asks you to speculate in responding with your answer, do not do that. You are not being marked based on how many exotic vocabulary words you know; a simple “I don’t know” will do better.

  1. Don’t Study

It is highly advisable not to ask about how the polygraph gets done for other individuals. Remember, a polygraph is to weed out your lies. Everybody tells different types of lies. Attempting to study for the exam or preparing for it by looking at how it’s been for others will only stress you out.
