Catching criminals red-handedwith lie detector test
Corruption are criminal events are on the rise these days with every crook coming up with new ideas to escape the arm of the law and it actually has become much easier to escape after committing a crime. Man’s brain has seemed to be developed over the years as he has found many different ways to commit crimes without getting noticed or without even leaving a trace. There are many ways to catch the criminals but even then after using all these there are certain innocent people being caught and attacked and blamed falsely. But all this mayhem might seem to have hit a dead end thanks to the lie detector test.
What is a lie detector test?
A lie detector test is a test that is used to catch a liar with some of the give-away characteristics of his/her body. The human body has so many actions taking place in it and when the body is put under pressure or any emotional stress like fear or worry or any such thing, then the rates at which these actions work seems to get increased and they become much faster than the normal rate at which they should be. Let’s learn how the lie detector test is actually done from the upcoming topics.
How is it done?
There are a few sensors attached at different points on the person’s body to measure and read the different signs. These readings are noted on a graph paper and they can be measured as per certain standards. The various parameters that are under scrutiny include a person’s rate of heart beat, their pulse rate, their perspiration levels, they rate of breathing, their blood pressure and some more parameters are tested. And all these are done when the person is asked a few questions by the examiner. At the start of the lie detector test, the examiner asks questions that are general and simple and then as the time goes by, they start asking questions related to the actual crime that had taken place. So if the above given rates of the suspect changes at any particular question, then they are charged with having committed the crime.
Although most lie detector tests promise to give us the accurate results, no one can actually give the right results because the person might already be having some issues related to the parameters being tested.
