E. H. Chapin once said, "A small lie, if it actually is a lie, condemns a man as much as a big and black falsehood. If a man will deliberately cheat to the amount of a single cent, give him opportunity and he would cheat to any amount." We spend a large amount of time trying to figure out if people are lying to us. Many people think they can tell if people are lying, others feel there are other methods that detect lies better. I believe that I can tell if my friend is lying, but not someone that I barely know. I feel that if you know someone well, it is easier to notice if they are telling the truth. Back when I was in high school, my little brother told me he was going to start for football. I knew that even though he was pretty good at football, there was no way he was going to start for his football team since it was his first year. If some random person told me that they started for their football team, I would probably believe them even if it wasn't true. Detecting lies by just instincts is not always the most accurate. Polygraphs are one of the most popular tests to detect lies. The polygraph test works by asking the suspect relevant, irrelevant, and control questions and evaluating their autonomic activity following the questions that are asked (video that shows the polygraph test, http://www.youtube.com/watch?v=xK6bp1Axvac). I think that the polygraph test is a better way of determining lies than using humans. I believe that the polygraph test is more of an arousal detector. If I was put to take a polygraph test I feel like I would fail regardless, because when they ask me relevant, I would be nervous about whether my autonomic activity would pick up and make it look like I committed the crime. Polygraphs are more accurate that humans when it comes to detecting lies, but I believe that there is no perfect way to tell whether someone is lying.
