Lie detection tests are widely used nowadays, more so by private investigators, to crack the mysteries of the truth. There are several clients ready to pay handsome fees to get their cases solved using a polygraph. Not all polygraph test results are admissible in court rooms but efforts of private investigators make it possible that these results are taken into consideration by the court.
While there’s still some level of disagreement about the admissibility of polygraphs in court rooms, with the increase in the number of professional private investigators, it is starting to have its day in court. If both parties agree upon using polygraph results as evidence, lie detector tests are accepted by courts.

Apart from conducting polygraph tests on their own men to verify the truth, the US and UK military are known to conduct such tests on their war prisoners as well. During private missions these military forces employ polygraph tests on their opponents to dig out the secrets.

Intelligence services also rely upon polygraph tests to a certain extent. The test results are usually included at times of job recruitment. Also, criminal cases, especially those related to sexual offenses are sorted out with the help of a polygraph. With increasing success rates of polygraph tests in solving sex offender cases, UK jurisdiction has now given green signal to polygraph test results for such cases.
