The lie detector is a wonderful piece of technology. It promises to help people discern the truth or the lie from what a person is saying, in response to certain questions designed to induce stress to the person being subjected to the test.
Basically, a lie detector test monitors physical manifestations that can develop whenever a person is under extreme stress. Theoretically, it can indicate when a person is lying – if a person is going over how to say a lie, there is supposedly a subtle change in the individual’s heart rates.
In addition, lying can also cause a person to sweat a little bit more than normal, due to the increased heart activity.
Due to that capability, a lie detector test can be useful in so many ways. Here are some of the applications or circumstances where a polygraph, as it is alternatively called, can be useful.
Weird as it may sound, lie detector tests can be used in job interviews. While people do misrepresent themselves sometimes when it comes to their skills, the use of polygraphs in employment interviews are actually meant to measure integrity and not really gauge the skill of a person applying for a job.
Let’s put it this way – would you like to hire somebody who has a weak sense of integrity? The lack of integrity can lead to unscrupulous behavior like corruption, fraud, dishonesty, and many others, that can negatively affect the image of the company.
It’s normal for anybody to deny being the perpetrator for a crime, especially when the person is indeed innocent. However, even suspects will want to get away and deny liability.
Thus, it’s very common for law enforcement officials to subject suspects and persons of interest in a crime to a polygraph test. With the help of trained experts and carefully chosen control questions, criminal investigators can hope to more or less establish culpability of a crime by using a lie detector test.
Investigative journalism is the most demanding of all forms of journalism. Because of its scrutinizing nature, journalists in this sub-genre needs to make sure that their confidential sources are telling the truth.
Remember, misrepresenting the truth can destroy a journalist’s career. Thus, it wouldn’t be a surprise if these journalists may want to use a polygraph while interviewing their sources so they can at least confirm that the source is not lying while giving information.
If a journalist think that a source is lying, whether fully or partially, he or she may decide to avoid publishing their accounts at all or, at the least, work extra harder to verify the information that has been given.
Of course, these are only just a few of the applications of a lie detector test. Visit us at https://www.liedetectortest.uk and learn more about lie directors, what they can do for your business, and why they are great at what they do!
