Beating a Lie Detector Test | I Didn't Know That

[@royjonesrampage6684]

lie detectors are modern version of calling a scientist a witch and burning him

[@GO10th]

How to cheat it: When you are sitting in the chair and the investigator asks you a question, just change the question in your head. For example: "Did you rob the bank?" In your head you change it to "Did you rob the bank(in your dreams)". Since you have not dreamed about it, you won't lie. Now you passed the test.

Lie Detectors are old technology and should be put out of comission What if a witness with social anxiety were being tested by it? What if he said "Yes" with honesty but due to his anxiety,the device tells it as a lie?

i was thinking the same, cause i have freakin social anxiety and i always look afraid and stressed ,and i sweat alot and specially my hands they are sweaty 24/7 !

[@Kim-md8bg]

exactly! that would be the worst situation i would have been put in

[@jacoboliver3966]

This might be a bit late, but it only tells you if you failed if there are any changes to your breathing, sweat, or pulse. So if you sweat a lot, then it will only detect even more sweat or a higher pulse. At least that's my guess.

@@carultch That can be true about anything youve been taught and believe in but if you asked them "can you prove its 6000 years old" then you get the lie or theyll just say "no".

Being stressed makes the lie detector detect stuff as lies. Also the thought of a lie detector makes you stressed.

[@rangel6242]

This is not true. Everyone is stressed when going into a new situation. The polygraph measures levels of stress when answering questions and you simply cannot intentionally turn off stress between questions.

[@OokamiShinjou]

@@rangel6242 Plus they do a baseline test for each person to avoid inaccuracies as much as possible. If you are anxious as a person, they'll treat that level as normal and anything higher as unnatural, as if you lied during the REAL questions. Polygraph tests are pretty flawed but not as flawed as people think. It seems people ignored the first part of the video pertaining to the baseline testing...

[@Jex134]

Polygraphs are essentially useless against psychotics and sociopaths. . Being a psychotic / sociopath isn't like the popular belief. In summation, its simply being able to decide to do anything you want, without the emotional ramifications everyone else gets. You can literally decide to feel guilt, decide to feel jealous, decide to feel afraid, and decide to feel nothing. . For that reason psychopaths can quite simply just decide to be emotionless, and undetectable for a polygraph.

[@nezpercenathan]

If you ever get a chance to test a lie detector operator, do this: Have him test 10 people. Tell him in advance that ONE of the people had to have stolen money, because there was money missing, and only those 10 people had any slightest possibility of access to the money. Do this when, in fact, there was NO MONEY MISSING to begin with! You will find that the polygraph operator WILL give you a suspect, every time! If his system was accuarate, there would be NO suspect.

[@amisfitpuivk]

Of course everyone is a lie detector expert on the internet, I'd expect nothing less. It's just so damn easy isn't it.

[@rangel6242]

I’m an examiner and I enjoyed your comment. Truly amazing what people think in here.

[@youbelong2me]

I actually had to take a polygraph yesterday. Before the test, I was interviewed and then hooked up to a machine where we tested out how it looks when I lie. They did this by handing me a mix of cards with a number on em and having me pick one. Then, I had to answer no to each number when he asked if the number I picked was such and such. I picked the number 3. When he asked about 3, I didn't even feel my heart pound any harder or faster or my breathing get any heavier. He guessed my number!

[@rangel6242]

He didn’t guess your number. You gave it away with fight or flight reflex when you answered.

[@tiemma4936]

But it takes time to process a false question in your head and by the time, since you'd listened to the investigator's question, you'd already have had a physiological response. That's just my guess.

[@ticks4ticks4]

Problem is: "Yes or no" questions--Can be subject to interpretation; also, what if you need time to think? ______________ Also, independent and irrespective of the "pass or fail" results---your "answers" can be used as evidence if you VOLUNTARILY agree to the lie detector test (potentially, anyways.

[@CrazyHorseInvincible]

Erjin Kim Guilty people certainly have. Aldrich Ames, Karl Koecher, Ana Belen Montes, and Leandro Aragancillo all passed polygraph tests while spying on the United States. Ames even passed it twice, as the video said. What's more significant is the fact that innocent people have utterly failed the test by failing to keep their composure.

[@adamopera3461]

CrazyHorseInvincible Im thinking the same thing. Innocent people usually failed to maintain their composure when questioned. Liers on the other hand because they are used to lying they have no problem pretending and act cool. So another point why lie ditctor is useless.LOL.

[@CrazyHorseInvincible]

Adam Opera The assholes giving these tests know they can't have too many false positives, or nobody would get hired for positions that screen with this crap. So after the test they question about "deceptive answers" they detected. If the person admits to some irrelevant or lesser offense related to the question. Or they adamantly say they weren't lying. In both cases the examiner just guesses or decides based on some quota whether or not to "fail" the subject. So really, the true polygraph test is the followup questioning. You better be sure the examiner likes you. Or doesn't already think you're guilty before the test.

[@puemor]

Actually, torture usually doesn't work. Its the threat of torture that gets to people. When they are presented with the possibility of torture, people will want to prevent the experience. But if they are already experiencing it, they know that they can handle it, as they have been doing thus far. Now, threatening to intensify the torture works too, just not as well.

Um- this is just a thought: Why didn't he remove the tack/ pin before the second half of questions? The way I saw it was that if the pin was causing still causing pain and then his stress levels rose it would have increased his rates. NB: I know that he probably wasn't pressing his toe against the tack for the second part of the interrogation...but he must have felt little pricks still.

[@mr.lonniebooker3205]

You have to have to score on a lie detector is a +6 or higher in order to pass the polygraph exam. +6 or higher on a polygraph exam represents known as no extreme deception indicated means Subject has told the truth. The other counterpart of a polygraph exam is the lowest score of a -6 or lower on a polygraph exam represents known as heavy amounts of extreme deception indicated means Subject did not tell the truth.

[@nezpercenathan]

I make it with absolute supporting evidence: the test was done at Western Sizzlin Steak House in Havelock, NC, in 1985. The polygraph operator was Jeff Melvin of Raleigh, NC. Only one example, but this was a real world test. He gave the name of ONE waitress. In actual fact, no money was missing, a fact not revealed to Melvin until later. There were actually more than 10 people tested, only variation between the example I show in my earlier post.
