Lie detectors do exactly what their names imply; they help to detect if someone is telling the truth or lying. The lie detectors made today are accurate by up to 98%, which means they can go a long way in helping to detect if the subject is lying or not. Over the years, lie detector test results have become integral parts of many government activities, including government recruitment exercises. Several other establishments also insist that their employees take the lie detector tests before being employed. Due to the high degree of accuracy, the lie detector test can reveal if the subject is lying or not.
Despite the high level of accuracy recorded in lie detector test results, it is still not admissible in the court of law as evidence. This is understandable anyway, considering the fact that many professional criminals have device methods to beat the lie detector and appear innocent of the charges against them. Also, the real innocent and honest people may find it difficult to control their anxiety while going through the lie detector test, especially if it is their first time. Consequently, the honest person will be adjudged as being guilty by the lie detector.
