Learning About The Use Of Polygraphs In Crimes

I love crime dramas, and I even love true crime stories more.  I regularly find myself watching these types of shows on TV, and I am always looking to learn a little bit more about them.  One of the things that I have found interesting is the fact that there have been a number of cases in which lie detector tests have been used to help authorities to solve specific crimes.  Now, these tests generally can’t be used in a court of law because they are not completely accurate when it comes to determining the truth in what someone is saying, but they have been proven to be helpful in a number of circumstances.  While trying to learn more about how lie detector tests can be used by authorities, I stumbled upon the website http://www.liedetectortest.com.  I found this to be full of info on the topic, and I even found a list of crimes that were resolved thanks to the help of the lie detector test.

It is important to note that both the questions asked and the person asking them are very important when it comes to the accuracy of a lie detector test.  There have been a number of cases where a suspect passed one lie detector test, then failed another.  There have actually been cases where the test helped to convict a person, then helped to get them released.  This is because of the fact that the test is not foolproof.  There are many different limitations with the test, and so it can’t really be used as a method to determine the guilt or innocence of someone completely accurately.  I find it amazing that there have been people who have failed one test only to pass another. 

The reason that the lie detector test is not completely accurate is because of what it is measuring.  It does not actually measure the truth of a statement that someone makes, but actually measures certain reactions that they are undergoing while they are answering the questions and making the statements.  One could be telling the complete truth, but be nervous while they are being questioned, and it could be determined that they are lying simply based upon this fact.  Meanwhile, someone could be lying through their teeth while also remaining perfectly calm, and the results of the test would indicate that they were telling the truth.  Unfortunately, there is really no way around this sort of thing when it comes to a lie detector test.  If someone is really nervous, or they just happen to be a really good liar, then the test might not have results that are very accurate.

Either way, I love learning about the history of these cases in which the lie detector test was used.  It is something that I find very interesting, and I am definitely glad that I found this website with all of this info.  If you are interested in this sort of thing, you definitely ought to check it out.
