Marc Bester from The Lie Detector
The UK Polygraph Association have received quite a number of complaints recently about a new examiner to this country from South Africa called Marc Bester or spelt wrong Mark Bester who has now hidden his name on his website which is the lie detector co uk.
As the UKs leading Polygraph Association and register of qualified examiners we are unable to stop Marc Bester from practicing however have denied him membership and explained our reasons to him. Yet still we have received more complaints from clients he has tested so this post is to educate any potential clients about Marc Bester.
A recent complaint that was very alarming concerned Marc Bester testing two thirteen-year-old children and allowing others in the room to watch and video, the poor children had no idea what was going on and needed to be prompted for every answer on the video circulating the internet, now removed to protect the innocent children. UKPA members would never polygraph a child, it’s not ethically or morally right. Nor would they allow someone else in the room whilst an examination was ongoing as it could disrupt the test.
The latest complaint is Marc Bester sending results via email (see picture) signed off with ‘I don’t take calls after a test to explain why a fail etc the results are final. A UK Polygraph Association Examiner will always fully discuss the result with a client and if the results are a fail will endeavour to find out why the subject failed where possible. More often than not this is done face to face after the appointment. Marc Besters approach is not professional and leaves his clients calling other examiners for explanations as it appears he blocks them. Used correctly the polygraph is a very good interrogation tool but post test interview is something UK Polygraph Association examiners will always do.
A good examiner and a UKPA member will always manually score all charts and will not rely on computer scoring algorithms, they will only be used as a guide. Sending any such computer generated scoring charts to clients is bad practice as they won’t understand them, especially if the examiner is refusing to talk to the client. We have three results, PASS, FAIL and INCONCLUSIVE, what if an examiner is to say to you that it was only just a FAIL, or only just a PASS, this will help no one and is the reason we have an INCONCLUSIVE result where the score isn’t enough to PASS or FAIL someone. Fortunately, the INCONCLUSIVE result is seen on a very low number of charts, usually less than 5%.
Marc will usually tell a client that he needs to get a second opinion on the data and get the charts computer scored and will let them know the results the next day, its at this point he blocks or ignores them.
Like many things in life you the client has a choice, in the case of a polygraph test the results can be life changing so make the right choice and choose a UK Polygraph Association member in the knowledge they are competent. A scalpel in the hands of someone with little or wrong training and bad techniques could just as easily kill rather than fix.
Here is the vehicle Marc Bester or spelt wrongly Mark Bester will arrive in, a UK Polygraph Association Examiner will maintain confidentially at all times and travel in a vehicle with no sign writing.

His website that he has now removed his name from is the lie detector or https://www.theliedetector.co.uk/
Marc Bester – August 2022 UPDATE –
Another complaint came in today, Marc has tested a foreign lady who understood no English and used her 12 year old daughter to translate. Surprise surprise the lady failed, how did he know what the 12 year old was actually saying ! A UKPA Examiner will only use a real translator and more importantly someone who is independant on the whole situation.
Marc Bester – August 2022 UPDATE –
Another complaint about Marc Bester, he tested two people accused of sleeping with each other and passed one and failed the other ! You couldn’t write it.
Marc Bester – September 2022 UPDATE –
Four more complaints this month, some very unhappy people who have received the wrong results. Our Chairman Michael Rumble has re-tested one who when tested properly passed as they should have with Marc Bester. The latest report was of Marc showing clients computer scores using an outdated algorithhm called OSS, replaced years ago by ESS, however no manual or automated scoring method can be expected to accurately interpret the results of a test that has been conducted improperly or ineffectively as Mr Besters tests are judging by the video evidence we have seen.
Marc Bester – October 2022 UPDATE –
Started the month with two more complaints, one from Tia who alledges Marc was with her 45mins and then said he needed to get the results checked by someone else, messaging her later with his usual Fail and blocking her from all contact. The next one was Brooke from Southampton whose partner he failed despite using awful questions and names, she has asked for the documentation and agan he has refused and stopped taking her calls. How many more peoples life’s are you going to ruin Marc?
Marc Bester – October 2022 UPDATE –
Hopefully the last complaint this month, this time from Megan who Marc allowed her 3mth old baby in the room whilst he tested her, she was quite obviously unable to concentrate on the test and again a common them here she failed. Subsequent calls to Marc were ignored until she was blocked, when Megan used another number he answered and said book another test and you will be alright. As you can appreciate this made Megan feel Marc was only interested in her money.
On Megans report Marcs words state ‘The examiner is of the opinion that the examanee has had some involvement in the matter under investigation’. Maybe next time Marc dont allow a baby in the room whilst testing the mother, no UKPA examiner would allow this major distraction that would seriously affect the results of the test. And again why use a partners names in the question, this is another trigger point and the case of a false positive result, next time use ‘your partner’.
