Some of the original lie detector test involved trying to use sweat and heart rates as a way to determine if someone is lying. The polygraph was the typical machine that is used to do lie detector test. While the polygraph may be know as typical and not reliable at times it it is the most accurate method of detecting lies that we have. There is a lot of belief that something happens in your brain when you lie that can be shown through graphs and exams. The way people get lie detectors verified is to take them to a court and put them to a test.
What are lies exactly? A lie is a made up state that someone attempts to pass off as the truth by withholding the truth itself. Most lies are made to either avoid telling someone the truth because they are afraid of how that person would react to the truth, or just to hide a dark secret. Of course there are other reasons people lie.
I personally believe that lie detectors are valuable and if the polygraph works now it has to be the best method of telling a lie. I do however believe that it is not perfect and engineers/scientist should keep designing better ones until one of them work. Other people of course believe that lie detectors don’t work and that everything said is a lie. Those are the same people that go on shows like Maury.
The science behind lying says that we when lying we first have to decide things like, how much trouble will we get in, is it worth it, and will we get away with it. We can’t lie more than our self worth. By that I mean we lie enough to maintain our image if we get caught. When tested studies show that people lie when it comes to money in-order to to increase their wealth. In society over 50% of adults lie every 10 minutes just because and almost 100% of children take that and begin their lying careers.
