In what cases should a lie detector test be used?
Many British citizens know of lie detector tests through American talk shows, but not everyone is aware that lie detection services are available here in UK. If a test is conducted by a competent and experienced polygraph examiner, the results have an average accuracy of 96%. Studies also show that by using the latest training, techniques and equipment (along with an experienced examiner), the accuracy levels are as high as 98%. These are the most common incidences where polygraph tests are used in the UK.
Most people generally associate polygraph testing with the criminal justice system. It can be a key investigative tool within the courtroom, but it doesn’t provide indisputable evidence. Polygraph services are available to defendants and also to government departments and law enforcement agencies. Using a polygraph service has become more popular as it speeds up trialling time and in most cases, at a lesser expense.
Lying in a family court has become increasingly popular within the past decade. Anything can be fabricated from a person’s income to their assets. Falsely made claims of child abuse and domestic violence have also been an issue. Now the accused can use a polygraph service to help in their cases and to ensure all parties are truthful.
Proving falsely made allegations
Whether you are accused of theft, fraud or going against a severe allegation like murder, a polygraph service can help you in proving your innocence. There was a case, based in Ireland, where a defendant (a county councillor) voluntarily took a lie detector test as he was being convicted of assaulting a man in a pub at Trafrask. He presented his lie detector results to the High Courts and they quashed his conviction.
Investigating new employees for corporations has been made easier since polygraph testing was introduced. Now recruiters are able to substitute curriculum vitae checks, drug screenings and security background checks by issuing a lie detector test. Not only would this significantly streamline and speed up the hiring process, it would also reduce the costs associated with hiring a new employee. It would also result in a more honest employee base. Even though this is more common for corporations based in the U.S, there is still many companies and government departments that would employ an examiner to give random periodic polygraph screenings in the UK. This is particularly common within government departments to ensure that there are total honesty and security in their line of work.
Corporate fraud and theft
Fraudulent behaviour in the workplace can take many forms. Misrepresenting a company’s financial information or activities is one of the most common cases. It’s done to mislead the public and to increase profits. When this is carried out and investigated, you can be looking at a sentence starting at 5 years for each indictable offence. You can use the results from a lie detector test to help your case or even get it overthrown.
Resolving domestic disputes
Polygraph services often play a key role in resolving domestic disputes. Many who wish to take a polygraph test are seeking peace of mind. The most common case for polygraph testing within relationships are accusations of infidelity. This can be as broad as being sexually involved with another person or used to determine the extent of your partner’s ‘sexual’ activities conducted over the internet. Polygraph testing can determine if visits to pornographic sites or dating sites were made but it is important to have an experienced examiner as it could make a difference in this particular area. The wording of test questions is crucial to achieving a successful examination as people interpret words differently. Other disputes can arise from accusing your partner of having a gambling or drug/alcohol addiction.
Verification of media sources
The 21st century has brought us new ways to find information like never before. The growth of social media allows anyone to share potential newsworthy stories. This has changed how journalists find and distribute stories, but with that comes an increased danger of misinformation. Sources found by journalists must be reliable or else the integrity of their publication could be at risk. If they question the honesty of a source, then a polygraph test can be a great way to ensure that the truth is being told. Many tabloids and magazines publish stories without fully examining their sources. But, if your publication values facts and honesty, a polygraph test could preserve your reputation.
