Can You Cheat a Lie Detector Test?

Being able to cheat a private investigator lie detector test is high on their list of objectives for many people. However, most of them will never reach this goal. This is because private investigators have put a lot of effort into the job of lie detection to make them more accurate than they used to be in the early days.

Private detectives have also changed their process to make matters a lot harder for people trying to cheat investigator lie detector tests.

The accuracy of lie detector tests has been challenged many times before but many of those challenges are based on tests that were not conducted under circumstances that experienced private detectives would normally use.

With regards to the devices, lie detectors have improved significantly since their early days. The lie detectors are made with higher precision and many of them are digital. This reduces the errors that arise due to movement of parts. This also allows for more detailed and accurate analysis by the private eye.

At the basic level, lie detectors are used by private eyes to detect lies because they are able to monitor specific responses in the body that are associated with lying. Cheaters normally try to trick private detective lie detector tests using methods that can fake these responses. These methods include:

• Stepping on a pin
• Focusing on a scary thought
• Taking a drug

There is more to a private detective lie detector test than measuring body responses.

For starters, some lie detectors also measure additional responses such as movements. Professional private Investigators have also learnt how to observe the test takers to know if they are ill, under the influence of something or doing something to manipulate the test.
