  • I think not only the machine is important. More important is the person asking the questions. Some psychological pressure could influence results.

  • I don't think lie detectors work 95% of the time!

  • I had a polygraph and it found that I masturbate

  • FBI polygraphers know that undetectable deception is impossible when using a Stoelting UltraScribe polygraph. Google "Quadri-Track ZCT"

  • 95 to 99% accuracy is the biggest lie of them all, and I think that woman in red is lying her ass off on camera.

  • 95 to 99% Numbers dont lie. So it is undeniably effective. No ifs ands or buts. Standard polygraph procedure is to ask the same question 3 times for a rough total of 4 truths and 5 lies. This man was asked to tell 2 truths and 1 lie.. He's probably a lawyer

  • If they calm you down and ask you some everyday control questions. Those needles shouldn’t start jumping when they ask you about touching little kids in an inappropriate manner. I SAY TEST THEM ALL.

  • clinching my asshole on questions where i told the truth worked for me.

  • ha polygraphs are a joke. just took one today for drug court. lied on every question pretty much. passed no prob. all they do is make u nervous make u think your gonna fail and try to get u to confess. the key: LIE!!

  • It's stunning there are idiots out there who still believe in polygraphs

  • I have to take one next week. Can someone who has taken on please message me and let me know how it went. So I can go in already mentally prepared. Goodbless

  • The polygraph is nothing more than a "thought" detector. That's IT.

    It proves NOTHING about veracity.

    You ask me a question - yeah, I'll have a THOUGHT about it. So what?

    When a polygraph is used to detect "lies", which is impossible, because there are merely different opinions about reality, have polygraph believers ever independently verified the truth of what the subject says?

    If you ask me: "Do you have a degree from Harvard?" and I say "Yes"

    have you called up Harvard to confirm?

  • Schermer is my new hero! lol

  • 95 to 98% accurate... and it was taken away because it was too effective. the kind of statements a liar would make, how ironic.

  • I can easily pass a polygraph test by clenching my asshole.

  • that retard calls it witchcraft lol

  • if they ask you some sort of shocking question.... id think you have some sort of reaction whether you actually "did it" or not. hmmm

  • Google "Quadri-Track ZCT"

  • Hahaha! "The Polygraph Protection Act occurred not because the polygraph is flawed or ineffective. It was taken away because it is *too* effective"!

  • @katiekawaii hahaha I literally laughed my ass off when I heard her say that!

  • It always makes me so uncomfortable that people get torn apart or lose their partners because of polygraph tests on The Jeremy Kyle Show or similar shows...

  • Try hooking them up to a fMRI machine and read brain state directly.

  • Personally I think you are a state paid polygraph shill:-)

  • Your studies are bogus, I can pull up a half dozen credible studies with similar accreditation to the contrary. I am currently looking at one for pre-employment screening where polygraph was deemed unfit due to its lack of reliability and false positives (innocent people are lying).

    Fact is, you have a choice as I do. You take your polygraph and place your shitty life in that state employees hands, thats your choice pal. Have at it, I'll refuse but thanks anyway.

  • And btw, I never said it never works lol.... I'm not the one making mad claims here. I said its not 100% trustworthy and its true and a scientific fact. Do some research of your own and you will see that I have done mine.

    Get me anyone with credibility to say it is 100% and I'll kss some ass and begin my apologies. Not to mention the human interpreter factor... I hope your tester likes you:-)

  • @guitarplayer4real--Flip Flopped & contradicted yourself, before you said it NEVER WORKS and now you're back tracking! Like a typical activist that claims to have scientific data to back his claims up but end up back tracking! Lie detector tests do work most of the time, and they much more effective today than before because of new techonologies applied. I'm glag skepted like the guy above exist becaus people like show the way which improvements on the technology can be made!

  • @guitarplayer4real--BTW there is so much more to the scientific community that the American Psycholigcal Association-which by the way in the last two decades has become a very activist driven organization where they choose particualr types of methodologies to produce result that coincide with their activitst oriented beliefs. This is the only Organization that opposes it. Many scientific studies have proven that lie detector tests are 90%-95% accurate. Something has to be done about the 5%-10%!

  • Talk about loud talking opinionated smack crackers... You can holler it as loud as you like but you have no science to back you, only opinion and interjection.

    The actual science behind polygraph is known to be debatable you schmuck! And somehow you are above that science, give me a break.

  • @guitarplayer4real-- Ahno but what kind of science do you have to prove that polygraphs are unrelaible and bogus and mustbe done away with. In the Scientific community they argue that Polygraphs don't work all the time but they do work most of the time, and those times they fail what the causes, can those causes be addressed to imrove the tests people take, and introduction of newer technology. Yes their are agenda driven activists that like to discredt this data to uphold a PC ideology!

  • There is new technology now.. They can map that part of the creative portion of the brain which is active when lying... But even that has been beaten with repetitive thoughts while lying in control experiments.

    Yep, as long as we have a choice in the matter you had better just refuse that polygraph test unless you have a really good lawyer along with you. Pretty soon with our governments new 'change' direction we will be forced to be "interpreted" by a state employee, its coming fast ;-)

  • Furthermore, actual test results from polygraphs range anywhere from 50% accurate up to 99% accurate depending upon who you ask. Of course you ask the polygraph expert and he is right every time, which of course has to be an outright lie. I know for a fact its wrong some of the time and thats enough for me. You polygraph "experts", and I use that term loosely, can cram it!

    Never take a polygraph, it should be abolished. Law enforcement will use it to railroad!

  • the green river killer passed a polygraph.....good thing the dna evidence is proven

  • Your experiment was total rubbish. The examiner already knew the answer and you knew that, taking away any motivation for lieing that causes a reaction.

    Doug Williams is also lieing about what a control question is.

  • How ever with new & improved technology & new forms of questioning, the 5% of unrelaibility that does exist will get solved.

  • @mrshutter77 It will never happen. You cant map the element of human diversity even with massive amounts of control questioning. Anyone around the subject of psychology knows this. For instance, someone suffereing from PTSD coupled with bipolar or personality disorder could not be properly controlled or measured and these types of traits run rampant throughout the criminal world. Another example are sociopath's who view evil in the same light as good, not a flinch!

    Its why some like BTK pass NP

  • @guitarplayer4real- Of course it can, polygraphs do work and have worked, you're just too much an anti-polygraph & your trying to find something in a tooth detail to say no, which is BS, Polygraphs combined with DNA testing can help lots of innocent people avoid jail time. Thanks to a polygraph test & DNA evidence on freind of mine was able to avoid a rape conviction which would have ruined his whole life--good thing the girl agreed to a ploygraph test, just like my freind, he passed, she failed

  • @mrshutter77 I am happy for your friend however that sort of evidence is called anecdotal. "My girlfriend was helped by Polygraph so polygraph is good". Scientifically this says nothing about the physical properties of polygraph science itsself, and that "science" is fallible at best.

    My comment had to do more with the actual machine and the facts behind it, not the people it helps convict. Thats the part thats open for interpretation by a state employee. BS huh? I have done my research.

  • @guitarplayer4real- AH no you haven't done your research your just spewing out BS because your completely convinced that polygraph tests don't work. It can help many many innocent guys from serving jail time & being forced to register as sex offenders when lots of cunt skanks make false rape accusation about them with no proof. Polygraph tests do work- and with improved technology like the one you mention that maps the portion of the brain that is active when people are lying it can work.

  • @guitarplayer4real--NO you haven't done you research you just like to listen to your own itching ears that polygraph tests do not work so you go looking for you own data that has an agenda of trying to say it doesn't work. It does! The very fact that you claim to have done you research goes to show you haven't done any kind of research, you just like to listen to your own choir along with lots of other leftist crakcers!

  • @mrshutter77 Well I also have personal experience in the opposite direction. My ex wife was given a polygraph at her workplace after monies were stolen. There was an on going investigation and they finally caught the gal red handed 3 weeks later.

    My ex wife suffered from PTSD due to childhood abuse, her doctors told law enforcement that she was a horrible candidate for polygraph and for obviously good reasons. They failed an innocent person, period.

    You are arguing opinion, not polygraph fact.

  • @guitarplayer4real-- An no I'm not arguing an opinion I'm aruging that ploygraph tests do work & they have saved lives. I seriously don't think this story your telling me is true, It's BS all the way! it's only form of technology they use to find out if someone is a lair, and it works most of the time! The times when it didn't they are adressing those issuing to make the test more effective with newer technologies, you saying that just because it doesn't work 100% it must be thrown out!

  • Two of my own freinds got saved from false rape accusations thanks to the polygraph test. One had charges cleared, the other passed the test & the accusor failed, but the proescutor asked judge to withhold it as evidence--so she can get a guilty conviction--and she succeeded, but it was reintorduced during his sentencing hearing--and judge told him he can continue to work & serve his sentence on the weekends. He still has to register as a sex offender.

  • Polygraphs are not flawed, they're effective, & can save many people's lives of wrongful accusations. Famous cases were presented. The guy was taking sides from the get-go, he talked to two people who are against ploygraph tests, and one who is for it, and he took his own test with a older machine, getting training from a guy to beat the detertor in the old machines. People opposed to polygraphs are people who still like to see women make all kinds of false rape accusations & get away with it!

  • Notice the man makes sense and the stupid bitch.. well she does what stupid bitches do--yaps nonsense. This is why women believe in astrology. More stupid bitch syndrome.

  • only a stupid cunt would believe a lie detector lol :) notice how fucking retarded and gullible women are hahaha.. the same dumb cunts who believe in astrology. Manhood101 . com

  • eople might just be nervous and fail this sucks

  • Here's how you can test a polygraph test's reliability. Conduct a study on a series of volunteers in which you KNOW the truthfulness of the answers and even ask them to lie on certain questions and see how accurate the polygraph really is in detecting lies. Counter measures are one thing but that is the best way to test reliability. That being said it's not like this thing can read your mind. There are no unique giveaways to a liar. Reading body language isn't perfect either.

  • Leave it to a lying false witness WOMAN to endorse a polygraph. I could easily show her wrong and beat her lying machine (then beat her with her lying machine).

  • maybe she should take the polygraph test. 

  • Just as extremely dishonest people can lie and make it say they are telling the truth, so can extremely honest people tell the truth and make it say they are lying. NEVER take a polygraph at the request of law enforcement. Refusing is not an admission of guilt. They will charge you and incarcerate you according to what that machine says. Cops are notorious for abusing their power with polygraph tests. Only a liar and false witness takes the word of a polygraph.

  • The polygraph test is more of a psychological tool for government agencies and the police force no where near hard science. Anyone who believes that a poly test is 95 to 99% effective is 100% tool. (Dean Moody)

  • I human lie detector like my self is much more accurate polygraph is 60-65% accurate and I'm 96.7%

  • Any investigator worth his salt doesn't need a polygraph to tell them is someone is lying. The only use that a polygraph serves is as an interrogation tool/scare tactic. "Did you do it?" "No" "the machine says you did!" "ok ok I did it!"

  • @BrooksForDelegate

    the machine doesn't say anything, yours are ignorant words, it looks even without knowing u that u doesn't now anything about this, i bet this is the first time u talk about this topic.....................

  • @JHARCAGU I cannot understand what you're trying to say. Please be on a 5th grade reading level before you debate me.

  • @JHARCAGU Oh, by the way, the majority of academia in the United States agrees with what I just said. Polygraphs are voodoo science.

  • i would say... the machine is a peace of shit

  • The polygraph is not one of the best methods for detecting the truth

  • She is one ignorant bitch

  • The polygraph is 60 to 65% accurate. It's better than simply guessing, but not highly accurate.

  • The only way to get the truth out of someone is to tie them down and tickle their feet with a feather.

  • anti-polygraph will give you everything you need to know about these frauds called polygraph examiners

  • get em michael

  • Much like an emeter in scientology

  • i have taking three polygraphs and lied on some of the questions and still pasted, these things don't work

  • a good enough agent could beat it.

    nor could it work on psychopaths because they feel no emotional difference between  breakfast and murder

  • wtf this is so stupid, polygraphs measures the reaction of people under stress, not lies

  • @2CSST2 Never take a polygraph!!! Its a choice given for 2 reasons by law enforcememt. 1st, if you deny a polygraph you are presumed guilty and the case will be pressed forward based on your decision. 2nd, you can take a polygraph and fail when innocent. The polygraph test giver works for prosecution and/ or the state, they bullshit in the back room and sip coffee together. I have personal knowledge of a locality in which prosecuters have never given a pass on a polygraph of a suspected criminal

  • I know I could have appeared to be lying on that machine when I'm not. When I show artistic work I've worked a LOT on to others, i often i get an adrenalin rush and a higher pulse by showing work i've put my soul into. It's hard to explain.

    We are able to emulate that we are lying even thought we aren't. Also uncertainty can appear as lying. If you say you walked 1 mile yesterday you can emulate that your lying if your not 100% sure it was a 1 mile, only approximate.

  • @wvguy8258

    Yeah, just because someone "fails" that doesn't mean they "failed" because of the questions that they "asked."

  • 7:15 paranoid fail

  • Fuck that cunt. Dishonest liar trying to keep her pseudoscience job.

  • i suppose if u want ur detect test worked out with no bias it should be at least under d condition that the testee s NOT AWARE of being TESTED. which u apparently cant do with this machine .

    want a real polygragh, try harder

  • what if you simply dont feel bad about what you did? also, would for example biting your toung (causing pain) help?

  • Polygraph's are still used so much in LE and Criminal Justice that it makes me sick.

  • MRI scanning in combination with display of photos are better. Showing images that a suspect could not have seen can provoke the visually perceptive regions of the brain to remember and rebuild the scenario in the mind. This is beyond conscious control, trials and matters of utmost importance should use modern instruments to search for lies and deception.

  • I suffer from intense panic attacks and anxiety disorder for about 5-6 years now (Im 22) and through trial & error Ive learned to control them enough to live a semi-normal life, hold a job, school, friends, etc. It took a while to figure out, a lot of times I get a wave of anxiety for no reason or when ppl mention certain things, Ive always feared taking a polygraph b/c the slightest fear may turn into full blown panic, making me fail even if I told the truth. So I dont trust them scientifcally

  • @Celtic505 how can you trust the machine if u can't even take control of yourself? of course, things like medical histories must be assessed at first before conducting the exam...

  • Well for 1 I don't trust the machine, and 2 I can control myself, I suffer from anxiety attacks, I don't lose control & have anxiety attacks. These machines only test whats going on internally, heart rate, perspiration, breathing, etc, not thoughts. & to me fluctuations in regular bodily functions dont necessarily indicate lying or truth. Suppose they ask you if you have used drugs recently but you have been sober for months & mere mention of using makes you anxious, they may consider you a liar

  • If you have problems with anxiety, you will fail the entire polygraph test, not just the critical questions, and so the results would be invalid. Easy questions like your name and age show up as lies because of how nervous you are, which discredits the polygraph as an actual lie detector.

  • They left out the "spiel" that the examiner says to the subject before starting the exam. It's usually a threatening overstatement of the polygraph's accuracy, and it either scares or enrages the subject. As a former investigator, I've seen someone repeatedly 'blow' a chart because they were nervous or had medical issues that interfered with heart rate, etc.

  • The polygraph isn't even used outside of the USA.

  • your very wrong body. Its all over Canada...

  • Canada doesn't count ;-)

  • And France, the UK, Italy, All the rest of europe, even mexico has them for gods sake, even every single middle easter country. Leave your house and stop bieng cought in the lie that the us is like the awsome advanced country or anything like that.

  • They are not used in europe at all. Nor in Australia.

    It hardly makes a country 'advanced' to use pseudoscientific technology. Advanced countries usually leave the woo woo behind.

  • Pollygraph is fucking stupid. It can fuck up just because you're nervous.

  • "Are you human?"

    Me: Yes

    Says I lied. Hmm.

  • Is that a fact or a joke O_O

  • how stupid!!! how can you say that the man subjected 4 polygraph examination is telling the truth where in fact he is really lying if the questions which were asked are not even related to him? think about this...will those questions make you sweat heavily? or maybe make your heart rate beat faster? his point of view is a nonsense...really foolish!!!

  • The fact that polygraph results are NEVER admissible in a court of law tells you all you need to know about them. Polygraphs are pseudoscience.......hocus pocus nonsense.

  • Polygraphs are useless. They give false readings and are ENTIRELY dependent upon how the tester reads the result. The fact that polygraph results are NEVER admissible in a court of law tells you all you need to know. Pseudoscience at it's best.

  • Polygraphs are worthless. I have taken 3 in my life. I told the truth on each question at each test. The polygraph said I lied on 2 of the tests. It was inaccurate. A 33% success rate = FAILURE. Polygraphs are useless.

  • I just took one for the LAPD. My first time. The eximaner tried to tell me it was like being afraid in combat. He asked how I felt in Iraq, and if I was ever afraid in a gun fight. What he tried to do is make me believe without a doubt, this fucking peice of shit machine will work, so that if I believe it to be a lie detector, thats exactly what it would do. So I pretended to believe his bullshit story. Let me tell u, this fucking machine dosent work for a god damn thing.

  • Its worth bearing in mind that some individuals (sociopaths, for example) do not have the same physiological responses to stressors such as lying and guilt as most people. Yet another problem for polygraphs.

  • Like the Green River Killer

  • I beleive that it works, but with a good training you can tell a lie and it will mark true

  • If she is right and the polygraph test was banned in private business because it invades privacy of employees too much......why not just ban employees from asking personal questions - I think we are doing that more and more aren't we? Employers could be restricted to asking only certain questions - like, is your job application true and correct in its claims? Who could oppose this? I don't think her logic makes much sense - any anyone enlighten me what she means by this?

  • If asked to take a polygraph to clear me of a crime, I would refuse, even if I were innocent. Polygraphs are frauds.

  • No they aren't.

  • Guess you weren't watching then...?

  • @Naiant Polygraphs are not frauds.

    They are simply a deviced used to monitor physiological responses. Why they are used as lie detectors when there are so many variables such as anxiety I don't know.

    Absolute rubbish.

  • @Naiant

    One more thing: there's a rule of evidence called the "rule against oath helping," which says that you can't ordinarily adduce evidence in court whose sole purpose is to bolster your credibility.

    ...Which means, of course, that subject to the rule, you couldn't even tell the jury that you passed a polygraph test.

  • Couldn't a polygraph be faked by using anti-anxiety medication. Such as Xanax or Valium to suppress your nervous responses?

  • See my comment in this same section where I said I took those drugs before taking a polygraph. Xanax, klonipin, and valium are all benzos. I was on klonipin and xanax.

  • Polygraph tests are not conclusive results for effective truth responses. I have had succes on test results from emotion control and physical reaction control to elicit desired responses.

  • Forget OJ, the top 3 worst spies in CIA history all passed multiple polys through their careers. Some people are simply not responsive by nature or life experience.

    The BS is when she says "95-99% effective." What does that mean? Is that 97% effective with 2% uncertainty?

    She claims 7000+ tests in 18 years? Working 5days/week, 48wk/yr, that's 7000tests in 4320d = 1.62tests/day on average. He did 6K in 10yr? Thats 2.5/day!! I'm not buying it. Maybe they mean indiv charts, not indiv people.

  • I've had to do this as a lab in school over the course of 2 weeks. It was even hard to pass when prepared for the exact lies on enough benzo's to put a horse to sleep.

    I don't doubt that someone can be trained, but it is very difficult. Even when you study the exact physiology.

  • it takes mind power and self control to trick a test not knowledge. Also, if those benzos put a horse to sleep you would not be awake (call me master of the obvious)

  • I agree with the mind power thing.. I tried meditating too while fucked up. I took enough to have black spots in my memory. I know that isn't enough to literally take down a horse, but I did my best. :-)

    I'm just saying it is really really really extremely very hard to beat. I'm sure it takes the cia lots of training hours.

  • did you watch the video? I doubt Shermer went through lots of training hours and he beat the test. The only thing the test measures is a physiological reaction, nothing mental, so if you can maintain your bodies calmness at all times you will pass the test.

    A detective gave me a polygraph once and told me the reason it works is not because of lying or not, it's because a guilty person is afraid they will get caught and go physiologically haywire(nervous) and an innocent person stays relaxed.

  • Your neurological processes are physiological. They take energy. When you think a thought, synapses are firing in that region of brain. It is not that easy to pass. I'm telling you I knew the questions, was drugged, and was meditating. I'm going to school for medicine, I know what I'm talking about.

    You can't just will yourself to not react, physiologically, without tons of training. That is my point. I thought people would appreciate the personal experience.

  • you choose your own thoughts. obviously there is no "anxious" reaction without your thoughts that initiate it. You couldn't control your body because you couldn't control your thoughts. If I had strong mind control I could initiate any kind of "emotional" response I wanted, I could initiate auto-nomic response at will, and turn off at will. do U agree that polygraph is testing for auto-nomic response? if someone was completely fearless would they pass the test? I doubt Sherm got tons of training

  • The point of countermeasures is not training yourself not to react to questions. You actually train yourself to over react on the control questions. Things like biting your tongue, alter your breathing, and simply imagining yourself falling over a cliff will cause a reaction. If you emit stronger responses on the control questions vs the real ones, you passed! Look up antipolygraph,org for a training guide.

  • But wouldn't a trained operator notice that and realise that you were trying to pull a fast one?

  • Notice what? That you're overreacting on control questions in the same way as a "truthful" person would do? The polygraph isn't a mind reader.

  • They'd notice that you are overreacting to innocuous questions. The machine can't read minds but the operators can certainly recognise anomalous outputs, and they'll know all about the little "countermeasures" tricks too.

  • I don't know why you would trust a cop over someone with 3 years medical training.

  • when I said detective I meant a professional polygraph administer that worked for the PD. I think what he said was that it wasn't necessarily lying that was a problem, but people knowing that they are lying and being afraid that the polygraph is going to catch them in the lie. If you have nothing to fear then what would be the point of an "anxious" body reaction?

    continued...

  • ...continued

    Thoughts of "fear" come from the mind and are the only thing that triggers a polygraph failure. Even if you knew you were lying but thought it was the right thing to do, you would pass the test.

  • Yes I said it was possible.

    No to the last part. I knew the question and was not scared of getting it wrong... I was in class. I couldn't pass it. When I knew the question it was less of a reaction, but there still was a reaction. I'm telling you, this is a lot different from what you think. You have to do it, learn about the physiology, and learn the machine. It is 1000x harder than you would think it would be, to pass. I was learning, ON the machine and couldn't pass it in 3 hours.

  • Also, I'd venture to say that the worst 3 spies didn't live to take a polygraph.

  • I'm sure they don't divide there tests evenly and make a point to do the same amount every day LOL! What else would they be doing with their time? There frickin polygraph administrators that's there job. It takes less than an hour to do a test.

  • Poly can work if the subject truly believes that the device/operator can do what they claim to do. In that sense, it is effective for interrogation. Then again, so would a Xerox machine if the subject believed it could detect lies by scanning their hand (al la The Wire season 5).

    Good operators can detect a large proportion of physical/medication countermeasures. The most effective CMs are mental, although I'm not advocating their use.

  • Polygraph wouldn't work on me. I would fail the question "Is your name [my name]", because I panic incredibly quickly.

  • OJ DIDN'T DO IT IT WAS LEMONADE

  • Haha "psychological billie club," great phrase.

  • o.j didnt do it lmao ok yes he did

  • The only lie detector is a hot rod in the ass, haha

  • control question; "Are you bricking it because you're hooked up to this rediculous machine?"

    "er........yes!"

  • dont belive this shit

    shit polygraph shit dosent tell the truth took it once

  • Amazing! I had no idea they were so easy to fool! Good to know!

  • "Anywhere between 95 and 99 percent effective." BULLSHIT! Stupid imbecile. Polygraph is nothing more than 20th and 21st century witchcraft - period.

  • I know fucking woman

  • Retired FBI Supervisory Special Agent Dr. Drew C. Richardson studied polygraphy for the federal government. Speaking to the senate, he said, "[Polygraph screening] is completely without any theoretical foundation and has absolutely no validity... the diagnostic

    value of this type of testing is no more than that of astrology or tea-leaf reading. ...(A)nyone can be taught to beat this type of polygraph exam in a few minutes."

    It's time we start listening to the truth.

  • The polygraph machine itself is not a lie detector. It simply measures physiological responses. It is the interpretation of the data that detects 'troubled area', not lies. Finally, the interpreter, or examiner, must be good at what they do. When the results show a 'troubled area', the subject is then further questioned about that area WITHOUT being connected to the polygraph. It is here that the examination typically gets subjects to confess. It is not valid if the subject does not confess.

  • these useless machines should be banned ,they use them on tv shows in the uk and you get people in tears just because some useless machine has said they are guilty ,when they are or maybe innocent

  • good video ,lie detectors are an expensive fraud

  • Time to upgrade the technology to EEG lie detection?

  • Grant, the asian guy from Mythbusters, fooled and EEG lie detector by thinking of very negative thoughts during the control questions, then very pleasant ones during the relevant questions, so his lies didn't stick out much from the control.

  • Correct. The EEG "lie detector" isn't accurate either. All Grant did was accept the fact that he was going to "fail," and he ended up "passing." All "lie detectors" are based on the premise that everyone stresses out when they lie. If you are comfortable with lying, or you stress out for some reason during these "tests" when telling the truth, they will either fail to catch you actually lying, or will identify you as a liar when in fact you aren't.

  • Listen to the psychologist in the video. "...the fact is that there is no reliable way to tell if someone is telling the truth or not."

    I don't think there will ever be a way.

    We need to start listening to the real scientists and subject matter experts instead of frauds protecting their own interests.

    "People who offer hi-tech solutions and all kinds of fancy gizmos that promise a way to give you the answer - that 's a very appealing promise to be able to make. But they're dead wrong."

  • "Polygraphers have been trained to detect countermeasures" What a load of shit. So if you go into a polygraph knowing to control yourself during questioning, they'll spot you and you'll fail based on that. And if you let yourself react naturally you have a good chance of failing also? Damned if you do, damned if you don't.

  • Polygraphers state that, but, if countermeasures are done correctly, they cannot detect them. The only countermeasure they can detect is the anal pucker , and that's only if they have a sensor in your seat. Dr. Richardson has issued a challenge to polygraphers that they will not be able to accurately detect countermeasures. This was done in a public forum, in front of federal polygraphers, eight years ago. His challenge goes unanswered.

  • The most polygraphers can do is claim they notice you are using them and hope you spill the beans. Don't buy the bait. That also goes for their spiel, "You are having a little trouble with this question. Go ahead and tell me what the truth is. the machine senses something." It's just a BS interrogation technique. Hold your ground!

  • Good points.

    G. Gordon Liddy is adamantly against the use of polygraph tests (as am I). About 10 years ago, when he still had his radio show in Washington, he interviewed a physician who trained people how to decieve the machine and the polygrapher. Nearly every person he trained in countermeasures during a 30 minute session fooled the polygraph test. On a related note, certain drugs such as beta-blockers and benzodiazepines can sufficiently relax a person into totally fooling the test.

  • So who are we going to believe? Psychologists who use science to study human behavior, or polygraphers who attend 10 week polygraphy schools?

    The American Psychological Association says that, "There is no evidence that any pattern of physiological reactions is unique to deception."

  • lol. right. The stimulus is that the question itself is something you'd almost be offended to have to answer. The practitioner is in denial. Jeez.. a good liar wouldn't be phased at all.

  • i have a poly coming up soon. Gotta do it to be hired by Morro Bay, PD.

  • you are the father

  • I personally wasn't given a law enforcement position solely on a false positive and the memory--and embarrassment--of being accused a liar still stings. It's time to stop using polygraphs altogether. The implications of false positives are too risky.

  • I'm sorry but I don't think this video added any new information. It is common knowledge that polygraphs can be tricked, and the woman claimed to be able to spot trickery. This video didn't confront that issue or the issue of whether a machine can accurately measure a person who is untrained in breathing control.

  • Thomas, yeah it should have spelled out in more detail. Perhaps Part 2 does. But yeah.. it doesn't work at all.

  • Whoever came up with the idea of the polygraph machine probably made millions of dollars.

  • Gary Ridgeway, the Green River Killer, was given polygraphs twice in the 1980's by the Green River Task Force. He passed of course, because he wasn't caught until 2003, by DNA.

  • Have any Ploy-Gaph tests been administered via questionnaire on paper, therefore without a detectives intimidation? The control ought be questions on paper against questions from an examiner. Not the present day 'one off' jest of examiner only. If this were done the test would not survive because contradictory results are designated: Inconclusive.

    The polygraph doesn't appear to be a reliable test mechanism.

  • There are countless times when the lie detector freed many suspects who later were found to be guilty. The CIA and FBI have both had double agents fool there lie detector, and even though Aldridge Ames (I think that's his name)lived in a mansion, they never investigated him because of him passing the test. It's way too subjective to trust any person to read it.

  • polygraphs are generally 80-90% accurate, about the same as a good detective. Polygraphs rely 100% on technique of the person giving it, as well as the opinion of who reads it.

    This host, by the way, is an idiot on most of the positions he takes but did a good job with this one.

  • I have been involved in a similar experimental test, and I beat it, a whopping 25 times out of 25 tests. It was only supposed to be three tests, but the examiner didn't want to lose. Well, I won, every time, and aced it. I am very good at controlling my heart rate, breathing, etc.

  • Yeah, but is Shermer a real skeptic, or a saurian infiltrator working under the auspices of the NWO? We won't know for sure until we hook him up to a polygraph and ask.

  • Skeptics FTW!

  • Boy, Dr. Phil needs to watch this

  • Polygraphs are never 100% accurate. If the person is nervous the polygraph will give a false reading, or if a person gets angery for being asked a certain guestion the polygraph will give a false reading. If the polygraph was any good, think of all the money they could save from having trials. The only place for a polygraph is on top of the scrape pile..

  • The polygraph test merely records physical changes, that's it. The lie detector is junk science. Even if it is 95% accurate, that is not good enough. No way. Would you want this stupid bitch judging you?

  • Skull, Exactly, I would only accept 100percent accuracy.

  • That detective is AWESOME

  • Understand, that what is being contested here is not that the polygraph can detect when someone is lying but rather that it can do so with near 100% accuracy. I personally have always disliked polygraphs because they can be used as a manipulative tactic against citizens. I personally would refuse to subject myself to a polygraph, even if I was innocent, and by doing so would incriminate myself. I think they need to be removed from the legal/judiciary process.

  • bitch

  • The proponent is using much newer equipment.
