How to Cheat a Polygraph Test - instruction
 

Throw off the machine's reading of the control questions by changing your blood pressure and heart rate. It?s difficult to do, but with practice, the next few methods and countermeasures will prompt your body to do so. Do some of the following when replying to control questions:


* Develop a breathing strategy. Throughout the test (except during control questions) maintain a normal breathing rate of 15-30 breaths per minute. Do not breathe too deeply. Then alter breathing rate with control questions. You can make it faster or slower, you can hold your breath for a couple of seconds after an exhalation, or you can breathe more shallowly, for example. Do this for 5-15 seconds, and return to your normal breathing pattern before the next question. As explained above, the polygrapher will compare your physiological responses to control questions to your responses to relevant questions. If the deviation from normal during control questions exceeds the deviation from normal during relevant questions, you will pass. If, however, you react more to a relevant question than to control questions, the polygrapher will perceive (rightly or wrongly) that you are lying in response to something relevant?you will fail the polygraph.

* Do math in your head. During control questions do something mentally complex. For example, count backwards in your head as quickly as possible or do some quick long division, as you are answering the question.

* Think about something exciting or frightening; think of things that make you ecstatic, fearful, or frustrated.

* Bite your tongue. Bite the side of your tongue hard enough to cause pain, but not so hard as to draw blood. Practice this in a mirror to be sure the polygrapher cannot detect it. This is highly effective, but may be detectable if you have to speak for an extended period, because you can?t bite while you?re speaking. Only use this method if you can give a quick ?yes? or ?no? response, which, luckily, will be most of the time.

* Insert a small nail or tack in the toe area of your shoe and press down on this during the control questions to elicit a pain response. This is a sound method, but it is easily defeated if the polygrapher asks you to remove your shoes.

* Contract your anal sphincter muscle when a control question is asked. While also highly effective, this method may (or may not) be discovered with the use of pressure-sensitive seat pads that are now commonly used.

Last two are intresting :) Wondering if anyone is going to try this on the new NBC show to win $500,000.

Do you think it will work?

don't plan on taking one of those anytime soon but thanks...:thumbsup

We had one of those in College, biggest scam machine of the century... Everyone lied their ass off and passed....

I can't believe they still require a polygraph to become a cop. The shit is so easily defeated. I know multiple cops that lied their asses off during the test, especially about drug use in their past.

I bet they work well against people who don't know much about them, but it doesn't take much to pass one of those.

i'm surprised mythbusters hasn't busted this shit wide open!

i heard the tac in the shoe ploy prolly 20+ years ago

are you lying now ?:winkwink:

Yea I knew that tac technique, I bet it'd work on the tv show

tack in shoe works. years ago i tried it in university with some friends, but its not easy to actually do. they hit you with test questions, during these you must "fake" your reaction quickly.

Starting to panick or get nervous is another method

Yes. * Think about something exciting or frightening; think of things that make you ecstatic, fearful, or frustrated.

Mythbusters did a few of them and all proved to be myths.

Not surprising....

I've heard that with lots of testing and practice, people can pass the tests.

I hate to be on that new show on NBC, tied up with my family and the millions of people watching, when my wife asks me a question that I know I will get fucked on :mad:

I'm pretty sure the proctor doesn't say "ok... now for a control question..."

I think they just randomly insert them, don't they?

I've taken a polygraph during a police dept application process. Prior to being strapped in, they hand you a questionnaire that has damned near any/every drug you can think of and any/every crime you can imagine and tell you to place a check mark by any drug you've ever tried/been around and any crime you've ever committed.... caught or not.

I wasn't about to let some stupid shit I'd done 10 years prior on a whim and as teenager get in the way so I lied my ass off.

The only question I didn't lie about was my name - and passed the test just fine. I played a round of golf in my head and listened to the questions in the background.

would be easier to tell the truth.

So, you I take it that you are not a cop now? Right, since you are posting on this board. Or you where a cop but ....

Correct. Being a cop was my dream job and if re-incarnation is really an option, in my next life....

I went through the written test, physical test, background check, polygraph, and oral review - passed them all only to find out the dept. was filling its' quota of minorities that hiring round, of which, I am not. I was ranked candidate #5 after testing out of a field of over 500.

Not long after, I got a job that paid $15K more starting salary per year and never tested again - couldn't afford the pay cut if I were accepted.

all you have to do is move your toes in your shoe. I drove them crazy when i was a little kid and they had me believing I didn't see something I saw.

Never believed in those things:pimp

Most of the moving and pain techniques are to easily caught now adays with the chairs and detectors they use.

:winkwink:You have to trick it with your mind :winkwink:

Thankfully that might happen once in a lifetime :)

Hmm thankx but I don't seeme being on one anytime soon. Oh wait I am Bond James Bond 007.. So maybe I might have to!

What are these used for now a days anyway? Becoming a cop? what else?

one of the first questions they ask you is if you have ever researched methods to defeat a poly test. :2 cents:

pulse poly's are quickly being replaced with voice analyzers.

HEHE i guess OJ's got good Ass muscles
