| Will a Lie Detector Test Lisa Vanderpump Took on ‘RHOBH’ Prove Her Innocence? - Showbiz Cheat Sheet Posted: 15 May 2019 05:10 AM PDT Lisa Vanderpump from The Real Housewives of Beverly Hills joked about having to take a lie detector test to prove her innocence. Even though it seemed like she was making a casual remark, she did something that surprised viewers. She actually took a lie detector test. About 24 hours after her meeting with Camille Grammer, cameras followed Vanderpump to a downtown location where she took the same lie detector test that would be administered in a criminal case.  "If she's lying I'm going to catch it in a second," the polygraph administer explained. Meanwhile, Vanderpump calmly smiles as Dr. John Sessa, her partner at Vanderpump Dogs looks on. "I'm re-thinking this whole thing," he laughs. How accurate are polygraph tests?The first (and only question viewers hear) is if Vanderpump gave a story to Radar Online. Viewers will have to wait until next week (seriously) to learn what else is asked and if she passes. But would this test actually provide the truth to whether or not Vanderpump did indeed plant the story? According to the American Psychological Association (APA), the test may not offer a cut and dry conclusion. For the most part, psychologists believe that there is little basis for the validity of polygraph tests. Even the U.S. Supreme court typically rejects the introduction of polygraph evidence because they are believed to be unreliable. Why are they so controversial?The APA refers to the tests more as a measure of tracking an individual's anxiety or fear. "The accuracy (i.e., validity) of polygraph testing has long been controversial. An underlying problem is theoretical: There is no evidence that any pattern of physiological reactions is unique to deception. An honest person may be nervous when answering truthfully and a dishonest person may be non-anxious." Essentially, the lie detector test uses instruments to measure an individual's physiological response to a series of questions. "The polygraph, like any other lie detection technique, measures an indirect effect of lying," Dr. Sophie van der Zee, forensic psychology expert, told BBC. "There's no human equivalent of Pinocchio's nose," she added. "But lying can increase stress… and with lie detection techniques you can measure the behavioural and physiological changes that occur when you feel stress." Can you beat a lie detector test?Even though the film Basic Instinct is a work of fiction, it was a good example of how someone could beat a lie detector test. Experts interviewed by BBC agree. "There's no question that you can beat a polygraph test but you really need the training to do it," Prof Don Grubin told BBC, who has trained polygraph examiners in the UK. He asserts while there are a number of websites that instruct users how to beat it, heading into the polygraph test with the goal of beating it may not produce the result you hope to achieve. Instead, if you want to beat it, you should practice your responses.  Bottom line, "It does not measure deception, which is the core problem," says Prof Aldert Vrij, an expert on the subject. "The idea is that liars will show increased arousal when answering the key questions, whereas truth tellers will not." Will this ultimately help Vanderpump?If the women already think Vanderpump is like famed chess champion Bobby Fischer, being cleared by a lie detector may do nothing to help her prove her innocence with them. During Watch What Happens Live, host Andy Cohen took an audience poll, which pointed to most people thinking the polygraph would exonerate Vanderpump. But Kyle Richards, who has known Vanderpump for years tweeted, "Are you kidding me ? NOOOOOO Who goes to these lengths? Who wrote the questions ? Who ordered the test ? #liedetectortest !!!!" Erika Girardi, who was a guest on WWHL agreed with Richards. Girardi adds this is not the way to go about trying to prove her innocence either. But one of Richards' Twitter followers pointed out, "Why wouldn't she take a lie detector!? Her supposed friends are calling her a liar and constantly bad mouthing her on national TV. Unlike some of the other ladies, #LVP has numerous successful businesses of course she would want to clear her name to protect her businesses." Check out The Cheat Sheet on Facebook!  |
| Is the Jeremy Kyle lie detector accurate? Science behind how polygraph machines work - Mirror Online Posted: 14 May 2019 09:21 AM PDT ITV bosses opted to suspend filming of The Jeremy Kyle Show on Monday, and take it off air pending review. The programme was cancelled last minute following the tragic death of guest Steve Dymond, who overdosed just days after failing a lie detector. Dymond was hoping to prove to his fiancee that he'd never been unfaithful, and was reportedly certain he would pass the test. Now, some fans have even called the lie detectors inhumane, and questioned whether they are accurate following his tragic passing. So, how to the Jeremy Kyle lie detectors work and can they be trusted?   Jeremy Kyle reportedly employ Guy Heseltine and Tim Burgess from Manchester's UK Lie Tests to run their polygraph. Costing £400 a test and taking a grand total of two hours each, the tests are complex and therefore highly accurate. However, the company are sure to assert that they can't guarantee 100 per cent accuracy. The test essentially calls on an examiner, who is a member of British Polygraph Association, to ask questions to the interviewee – having pre-agreed what they're going to be faced with.  The experts then track changes in the subject, which may indicate a physiological trigger that they're not telling the truth. These include a change in blood pressure, sweaty palms and breathing. The breathing is measured by two rubber pneumograph tubes on the subject's upper chest and abdomen, while adhesive pads on their hands or fingers measures the sweating, and a cardiophygmograph keeps tabs on blood pressure and pulse. Alongside the test itself, subjects are given a pre-test interview, and their answers are put into charts which are then analysed by the examiner.  Despite their rigorous approach, UK Lie Tests confirm on their website that "no test process can be guaranteed 100% certain". They do, however, promise that the test they conduct is "reliable" and, when done properly, proven by over 200 studies. Plus, they give all their examiners anti-countermeasure instruction to ensure they spot a subject trying to cheat. Discussing the use of the tests on the show after the heartbreaking news of Dymond's death, one member of the public wrote: "Lie detector tests are pseudo-science. "Talking people into going through them on air with huge real-world consequences for themselves – their marriages – is modern day bear-baiting. This show should be cancelled. Or at minimum, end its use of the tests." While another agreed: "It is disgusting that Jeremy Kyle and registered psychotherapist and mental health nurse Graham Stanier were able to convince the UK audiences that lie detector tests are '99% accurate' when this HORSES**T. "Remember how many guests claimed the test was wrong? It probably was." Mirror Online have contacted UK Lie Tests for comment. Do you have a story to sell?
