London Polygraph Examiner Misconceptions
As a London polygraph examiner, I visit misconceptions about lie detector tests all over the net. Sometimes they infiltrate other media outlets and newspapers. It is time we dispelled them to provide a balanced view. Below are some of the most frequent misconceptions.
Lie detector tests detect lies
No, they don’t. By monitoring psycho-physiological responses to formulated questions lie detector tests discover deception. Polygraph equipment finds changes in cardiovascular, respiration and electro dermal activity. The latter relates to perspiration that alters the properties of the skin.
Arguments that these answers are found in conditions when an individual is not lying are valid. Natural anxiety can cause psycho physiological reactions that are similar if not exactly the same. Until the evaluation is administered professional polygraph examiners take natural nervousness into account and the gear is set.
Examination results aren’t wholly reliant on the equipment. The examiner’s qualifications and expertise are equally vital in the procedure. Let us face it, if you want a carpentry job you are not likely to use a hammer. You may employ a carpenter who understands what he’s doing with it and wields the hammer. Likewise, you don’t use a machine without an examiner.
Polygraph tests don’t work
This misconception is all about because those saying it believe that the polygraph finds lies. It does not, as mentioned.
It functions as an investigate tool. It’s hardly likely that the Ministry of Justice at the UK would make taking examinations a compulsory state for specific kinds of offenders when they are discharged from prison on probation, if this wasn’t the case. It’s even less likely that they would be used by many UK police forces, including the Met and Essex yet they do. Indeed, they have grown increasingly utilised.
In the justice system the polygraph is instrumental in pointing detectives to boost their investigations. By way of example, a requirement of a pedophile’s release on probation might be that he shouldn’t get or download pictures on the internet. Questions can be asked in periodic, compulsory lie detector tests to determine whether he’s broken that state. If deception is located, the computer will probably be confiscated and examined. Since these polygraph tests have been implemented over 300 offenders are sent back to jail. The polygraph is functioning well in these cases.
You can beat a lie detector test
As a London polygraph examiner and capable psychologist, I have to admit to being amused by efforts. The favorite is bad breathing exercises timed incorrectly and not only obvious to the polygraph but the examiner as well. The proven theory is that these responses will create inconclusive results or achieve a fail with the result of Purposeful Non-Co-Operation PNC.
Our training in forensic psychology has provided qualified examiners me with the ability to spot a scammer a mile off as well as the polygraph identifying unusual trends.
The above are the most frequent misconceptions but there is also confusion regarding the use of polygraph results in courts.
Lie detector evaluation proof
It has been responsible for turning frustrating investigations into ones that were effective although evidence is not often used in courts. The polygraph can open new avenues for them to explore when detectives reach a dead end.
However, just as a judge would not convict eye witness testimony on, he or she wouldn’t do so based on polygraph results. All evidence of any type must be backed up with additional evidence for a successful prosecution or defense.
Lie detector tests are frequently permitted in industrial tribunals and are often noted in court.
