Lying, it is apart of everyone's lives even though it is so frowned upon in society. It is moral's worst enemy. Studies have shown that college students will tell about two lies per day! So, when can we tell if someone really is telling a lie? There is no right answer, research shows that there is only about a 50-50 chance of being right, but average population shows about 55% accuracy. With these statistics, how are polygraph testers a whopping 98% accurate? It turns out that these can actually be quite misconstrued. In fact, it can pick up false positives (innocent people who are labeled as guilty, even when innocent). In addition, a polygraph test can confuse arousal with guilt, which jokingly got its name as the "arousal detector" rather than the "lie detector". So a suspect to a crime could be feeling an emotion other than guilt like anxiety when answering a question and the polygraph would pick up on it as a lie rather than just anxiety in itself. It also picks up on false negatives (people labeled as innocent even though they are guilty). So, if there are so many problems with this, then why do so many examiners insist on using such a non-liable piece of equipment? This can be answered by the sole fact that a polygraph elicits confessions, especially when the victim is guilty. It is a shame that it is still used though due to the fact that all of its results lead to the fact of how unfalsifiable it really is.
