They say you can run a hundred miles with a lie, but you can never hide from the truth. But before you can see through those sweet words and dignified composures, at the highest accuracy possible, you will be needing the help of a polygraph test.
Known for its common moniker “lie detector test”, the person who will take the test will be connected to a machine where his/her stimuli and physiological responses to certain questions will be evaluated. To increase the accuracy of the test, only licensed investigators are allowed to read and analyze the results and tell whether a person is stating a fact or just weaving a story. Also, a polygraph test will only be considered legal and ethical if it is conducted by a licensed operator.
In actual fact, recent studies from psychology prove that the physiological responses a person experience depends on the type of situation he/she is in. Such as when a person states a lie, he/she will undergo gradual changes internally but is not easily seen physically. As a result, experts managed to formulate a method to see through a person, and that is by examining these internal changes- through a polygraph test.
While the said method of determining the truth continues to reap tons of recognition around the world, many are already opting to utilize this for their own good. In fact, polygraph test has done a tremendous improvement in terms of the social research network. Many social scientists use this method to identify how nervousness affects the way people respond to questions. Social experiments such as the one mentioned were conducted with interview prior and subsequent to the test.
Aside from that, the polygraph test is also a blessing in disguise to some companies. The majority of the companies here in Las Vegas have a certain anti-theft policy, which grants them the power to conduct polygraph test Las Vegas where they can pluck out the plausible culprits. Aside from filtering their current employees, this method can also be a great lift to screen future employees.
Although the first two might seem unfamiliar to some, perhaps the most popular use of polygraph test comes from the judiciary side. Through the years, lie detector tests are known for their vital role in searching for the truth from the statements of the witnesses and suspects. However, one must remember that polygraph test is not a widely recognized method to establish the culpability of the defendant.
