The reliability of the polygraph test is one of the most frequently asked questions by clients and examinees. People want reassurance that they can rely on the outcome of the test, but it’s important to understand the context in which the polygraph is used.
Many organizations now use the polygraph in a controlled environment where the outcome can be verified, proving the value and accuracy of the tests conducted by professional examiners. While polygraph tests are not yet admissible in evidence at court in the UK, many organizations associated with the legal system and security services rely on the polygraph as part of their investigations.
For example, the National Offender Management Service uses the polygraph to monitor potential reoffending of sex offenders who are released early into the community. This has resulted in many offenders being returned to prison because of admissions made pre or post-test, which has saved more children from going through abuse.
The UK security services also plan to use the polygraph on “terror informants” who provide critical information to keep the country safe. Polygraph testing is already used effectively as an interrogation technique in several other countries and is finally gaining recognition in the UK.
Polygraph testing is also used to screen personnel for sensitive positions. After several publicized data breaches, companies now have a need to test potential employees to make sure they are suitable for high-level security clearance.
The value of the polygraph in investigating crime is clear. Working with mentors and colleagues abroad, professional examiners have seen the impact of the test on guilty suspects and how it can be used to clear the innocent. There is a sense that the tide is turning, and evidence-based analysis through the use of the polygraph will become the norm in serious investigations.
The key to the reliability of the polygraph lies in maintaining the highest standards of polygraph training for examiners and employing the right professional for the role. That’s why examiners at Lie Detector UK Services are handpicked for their experience in both polygraph testing and investigative skills.
In conclusion, the polygraph is accurate enough to protect the most vulnerable and identify the most deceitful. With more organizations recognizing its value, it is becoming a more reliable tool for investigating crime.
