Lie detection is also called as deception detection by some. There are also those that call this as a polygraph test. This process is all about obtaining information from the person’s reactions to the questions that are asked to him or her. A lie detector is a very important tool in solving crime cases, and other activities, as it tells whether a person is lying or not.
Favorite Tool of Law Enforcers
This is one of the reasons why law enforcers usually rely on these lie detectors to know the truth for someone. It has also been proven time and time again that it indeed is a reliable way to know is someone is lying or not. As of now, there are a lot of technologies incorporated in lie detection machines.
The U.S. National Academy of Science even recommends the use of lie detectors as this can effectively tell whether a person is telling the truth or not, through the observation of various physical reactions to the questions that are imposed to a person. As of now, there are already a lot of improvements to these lie detector machines.
Technological Developments in Lie Detection Tests
One of it is the new transcranial doppler technique. This technique is more accurate in knowing whether the person is telling the truth or not, as it observes the neural pathways of the person. In simpler words, it is more accurate because it analyzes the brain processes that connect to the nervous system.
With all of these being said, it is still important to know that despite all of the technological improvements and claims done by lie detector machines, people should not still rule out the possibility that these machines may still be wrong.
