Visitors to science festival can witness live lie detector test
VISITORS to the British Science Festival in Newcastle tomorrow (Saturday, September 7) will get the chance to witness a live lie detector test.
The test is part of an event called Polygraph On Trial which is one of the first events of the British Science Festival which opens in Newcastle this weekend.
The event explores the reliability of this famous test, which assesses a subjects truthfulness based on their physiological responses to a series of questions.
Despite accuracy levels of more than 80 per cent on average, polygraph evidence is not currently admissible in legal proceedings in England and Wales.
The event will discuss the reasons why, while arguing the case for their reliability and will include a live polygraph test.
Dr Michael Stockdale, of Northumbria University's Centre for Evidence and Criminal Justice Studies, is one of the academics behind this event, alongside Professor Don Grubin of Newcastle University and experienced private polygraph examiner David Bird, a retired UK police officer with experience of using polygraph in criminal cases in Canada and Belgium.
Dr Stockdale said: "Critics of polygraphy assert that it lacks a clear theoretical basis and challenge its reliability, but the US American National Academy of Sciences found that reliability falls within the range of 81 per cent up to 91 per cent, depending on factors such as the type of test and the skill of the specific examiner.
Polygraph on Trial has been organised by Northumbria University and the School of Law's Centre for Evidence and Criminal Justice Studies. The event takes place during the British Science Festival in the Fine Art Lecture Theatre, Fine Art Building, Newcastle University, from 4pm-5.30pm on Saturday 7 September. The event is free, but booking is required.
