About Lie Detectors


Do you think you're good at determining whether someone is telling the truth? Having such an ability can win cash for the contestants on this show hosted by Australian TV personality Rove McManus. "Lie Detectors" features three comics who present a mixture of outrageous facts and lies to members of the studio audience, who double as the program's contestants. The audience member who gets the most correct answers -- trying to figure out whether things like celebrity tweets are real or fake -- in the fastest time earns a prize and the chance to face the comics in a final round for a bigger cash prize. … MORE

True story? Lie detection systems go high-tech

Feb 16,2020 7:44 am

Prof Yael Hanein sticks A Number of electrodes to the Left Side of my face.

" Move your eyes, blink, smile. Now try to relax, " she says. " We will see if you are a good or bad liar shortly. "

Prof Hanein and colleague Prof Dino Levy lead a team at Israel's Tel Aviv University that have developed a new method of lie detection.

They say they have identified two types of Liars - those who involuntarily move their eyebrows when they tell a fib, and those that cannot control a very slight lip movement where their lips meet their cheeks.

Their software and its algorithm can now detect 73% of lies and they intend to improve that as they develop The System . " When you try to conceal a lie, one of the things you try to avoid is any sort of body reaction, " she says.

Prof Levy adds: " But it's very, very hard For You to conceal a lie with this technology. "

Methods of lie detection have probably been around for as long as Tall Tales have been told. One of The First documented examples comes from 1000BC in China,

After a period of time the grains would be checked, and if they remained dry then the person was determined to be guilty. The theory was that if the individual had indeed lied he or she would be fearful or nervous, and therefore have a dry mouth.

The early 20Th Century saw the invention of The First lie detection machines or polygraphs. The Most well-known of these is the " analogue polygraph" which typically has three or four ink-filled needles that dance round on a strip of moving paper.

The Suspect has sensors attached to their fingers, arms and body and The Machine then measures breathing rate, pulse, blood pressure and perspiration as they answer a series of questions.

Yet there are So researchers and technology firms around The World are working to develop more high-tech polygraph Systems .

At Erasmus University in Rotterdam, Netherlands, Dr Sebastian Speer and his team are using an MRI (magnetic resonance imaging) machine to spot if someone is lying or cheating. They do this by looking out for colour changes in brain scans in response to questions.

" Essentially we see [different] areas [of The Brain ] that are more strongly activated [Light Up on the scans] when someone decides to cheat or to be honest, " says Dr Speer.

One high-tech lie detection system already in use is EyeDetect from Utah-based firm Converus. This focuses on involuntary eye movements to detect lies.

A subject is asked to answer A Number of true or false, or yes and no, questions. As they do so, eye tracking software watches and studies their responses. The result is then provided within Five Minutes , and it claims to be 86-88% accurate.

Converus (The World is Latin for " with truth" ) says EyeDetect is now used by More Than 600 customers in 50 countries, including over 65 US law enforcement agencies and nearly 100 worldwide.

Chief executive Todd Mickelsen says The Test is being utilised by authorities and firms to screen for numerous things: " These could include prior crimes, drug use past or present, unreported disciplinary action, lying on a job application, terrorist ties. "

Meanwhile police detectives can use EyeDetect to ask specific questions regarding A Crime .

It is important to stress, however, that the legality of Lie Detectors varies greatly from Country to Country ,

is a series exploring how technological innovation is set to shape the new emerging economic landscape.

In the UK, polygraphs have been used by the probation service

But the results of polygraph tests cannot be used in criminal cases in the UK's three separate legal Systems - England and Wales, Scotland and Northern Ireland .

At the same time, but this has to be optional.

In the US, with the further complication of US-wide federal law on top.

For instance, California allows lie detection test evidence in state-level Criminal Court cases if both sides agree, yet in New York state it is not allowed under any circumstances. And US police forces cannot require that a suspect or arrested person undergoes a test.

Meanwhile, The Federal Employee Polygraph Protection Act prevents firms from putting job applications through a test.

Former CIA officer Christopher Burgess cautions that Lie Detectors should not be been seen as the be-all and end-all for proving the guilt or innocence of criminals - or spies.

" It's one tool used during The Interrogation phase of an investigation, " he says. " Evidence is how Liars , scoundrels, cheats and fabricators are sussed out. "

Mr Burgess, who is now a security analyst, adds that the devices are not completely accurate, and says that he himself was once wrongly implicated by a false test result back in the mid 1990s.

As more high-tech lie detection Systems enter use, he says there remain " ethical and moral questions".

Back at Tel Aviv University, the researchers hope that the electrodes will eventually be replaced by video cameras and software able to spot a liar from a distance or even via an internet link, based on facial muscle movements.

" In The Bank , in police interrogations, at The Airport or online job interviews, high-resolution cameras trained to identify movements of facial muscles will be able to tell truthful statements from lies, " Prof Levy predicts.

After my interrogation I ask if I have passed.

" You're not a very good liar, " the two professors Jest .
