Can You Lie On a Lie Detector Test?

There are many people who believe wholeheartedly the results from lie detector tests. As a result, many people believe that if they can find a way to beat private investigator lie detector tests, they can get away with a lot of things.

There have been numerous attempts made to beat lie detector tests conducted by private investigators over the years. Although some of these attempts were successful, there were other factors that contributed to this. As a result, modern professional investigators have developed many ways to limit the possibility of anyone tricking the test.


Accuracy Of Lie Detector Tests Conducted By Detectives

The accuracy of a lie detector test will depend on several factors. These include:

  • The skill and experience of the private detective conducting the test
  • The setting in which the test is conducted
  • The quality of equipment used to perform the test
  • The physical fitness of the subject of the test

A good private investigator must know how to mitigate the negative effects that can be caused by instruments, environment and fitness of the person taking the test. This is why skill and experienced are such important factors.

At the end of the day, an investigator working with the best tools but lacking the necessary experience can't deliver reliable results while an experienced detective can achieve accuracies of over 90 percent.


Why Would Someone Take A Test Knowing They Would Lie?

It's not unusual for someone who is guilty to take a stance that puts them at risk of being exposed. Many people do this in the hopes that you'll take their willingness to be put to the test as proof of their innocence.

When someone who is guilty offers to take a lie detector test, quite often, they do so hoping that you won't take them up on the offer. After all, the fact that they're willing to submit to the test shows that they're willing to do whatever it takes to prove their innocence.

Surprisingly, this tactic works and many private eyes can tell you of clients who paid the non-refundable deposit and in the end didn't take the test. This is a bold tactic that many dishonest people have learnt to use. This is also why you should always proceed with the test if you already agreed to it.

Some people also agree to take lie detector tests either because they don't believe they work or because they believe they can outsmart the machines. As many of them find out, they're usually wrong.


Ways That Someone Would Try To Beat A Lie Detector Test

There are a few ways that a person can try to cheat a private investigator lie detector test. These include:

  • Making sudden movements when answering control questions
  • Inducing sudden pain when answering control questions
  • Thinking scary or stressful thoughts during control questions
  • Taking a drug that relaxes the body before the test
  • Answering simple questions with complicated answers

The use of these methods is supposed to trick the machine. However, it takes military operatives years to perfect these skills, which means the average person is unlikely to master the means to confuse the machines overnight. Additionally, while it's possible to get the machine to register a false reading, it's not so easy to trick the investigator if they have the necessary experience and skills.
