i have to take my first poly and i am nervous as hell. on the CQ's if i am doing the biting tongue counter measure do i bite my tongue after the question is asked or after i answer to raise the spike? also how does biting the tongue cause a spike? does the pain increase my blood pressure? same goes with the ass spinctor technique? thanks

Sir,
If you bite your tongue before you answer, the examiner will surely observe you.
You have to open your mouth to answer 'NO' and then as the 'O' trails off, slide your tongue between the molars (on the side away from the examiner), so that as your mouth closes, you can give yourself a good
hard bite on side of tongue.
You do that immediately following your answers to the Control Questions.
According to research quoted by the APA, the tongue-biting measures can reduce the efficiency of this test by approximatly 70%.
You can also effect the anus-pinching at the same time, but do not overdo that one. Probably you will instructed to sit on an electronic cushion, that one is designed to detect the anus-pinches - so practise the pinch and just do it slowly and to 50% of maximum pinch and hold it pinched for about 5-10 seconds.
The tongue-bite will cause bigger reactions in the galvanic skin reactor
(GSR) and usually also a same-time bigger reaction in the cardiograph.
The anus pinching can result in also increased GSR and altered cardio and respiratory traces.
The key factor is do not overdo it and practice the tongue biting using a mirror so you can perfek it without being observed.
At the start of your test, be very polite to the examiner. Ask him if he is related to a movie star. Give him a chocolat.

Brilliant. The perfect recipe for a failed polygraph test. Nothing says "I am engaging in countermeasures" like the phony reaction given by the physical pain response. I am afraid that Mr. Hasselhoff here is telling you to invest in subprime mortgage markets. There again, the Germanic people are not known for their subtleties.

Sir Johnson,
The examiner cannot differentiate between pain induced arousal or natural arousal. The tracing is simplistic. All it can do is go up, or down.
Germans are known for their pragmatism and inability to swallow ballshit while thinking it is maybe a black forest cake.
The lies of the polygrapf examiners are now well known worldwide.
The polygrapf industry is in panic. The end for them is close I think.

Not true Hans ole buddy. The polygrams present with many notable differences regarding artificial versus natural. You are essentially saying that examiners cannot differentiate between tar pools and tire skid marks----and speaking of skid marks;

Why do you "have" to take your first poly? Why are you nervous? What are you trying to hide?

Nixon once said "I don't know if the polygraph works or not, but it sure scares the hell out of people".
i am nervous because i am applying for a job and i have done somethings in my past that i know they will ask me. so can somebody please explain how biting the tongue causes a reation on their graph? what it does physically to your body to cause such a reaction?
beezy,
The answer to all of your questions can be found in "TLBTLD" which is available for free on this website. I strongly suggest that you carefully read the booklet, and educate yourself about polygraph testing and the methods involved.
The booklet specifically addresses multiple polygraph countermeasures to include tongue biting and the anal sphincter technique.

Let me put it this way. Your polygraph examiner, after recording your "graphs" will have seen your natural arousals and if you attempt countermeasures, he will view your corny ones. Think about it this way----here comes an analogy. Your examiner will be differentiating between a fake laugh, and your real, full bodied laugh. To make matters worse for you, your examiner has probably attended a hand ful of the latest "spotting fake laugh" seminars. We as a profession are much better at detecting such artifacts than we were say, 5 years ago. According to my anecdotal experience, and recent research on TLBTLD countermeasures------you will sink like a led zeppelin if you goof with your test. Bummer.
i am going to take a 50/50 chance of beating the machine by applying countermeasures versus a 100% of failing or not getting this great job.
i have downloaded and read the literature in "TLBTLD" i am still having problems understanding what are control questions and what are irrelevant questions. i know what the relevant questions are. "is the light on in this room?" i would of thought that is a control question. can somebody explain the difference? please
No matter what happens, let us know how it goes! ::)
thanks. but i dont see how anybody can prove i used countermeasure, they can assume but its their weird against mine but can anybody answer my questions to my last replay?
Beezy, I don't understand how you could have read TLBTLD and not understand how countermeasures work or how to implement them. It's not rocket science, maybe you should read more carefully.

Call me crazy, but your post does two things Trippy.
1. You are giving the poster advice that will most certainly result in his disqualification.
2.You are aware that poster plans on deceiving law enforcement regarding criminal issues---which is that you knowingly are recommending him/her to engage in obstruction of a law enforcement investigation. The only ethical and legal excuse you have would be that if the poster is attempting to gain employ with an armored car company.
Either way, I would hope that Sarge would have something to say about you encouraging poster to attempt to defraud law enforcement.
What would your momma think?
what if i apply countermeasures on irrelevant questions? ie "is your name catrin" can somebody explain examples of control questions so i know what to look for?
i am applying for a military job. but my past of 15 years ago or more has nothing to do with how well i can do the job now. and if lying will earn my family more money and help get us out of poverty i will do that everyday of my life to send my kids to college.
The military eh...I thought you wanted to "get..out" of poverty, not shower in it. ;)
Oh for goodness sake. Your either trying for a intel position, criminal investigator position, or any such position thats going for top secret. You made three mistakes so far. One, you have an upcoming polygraph in the military (army, airforce, and maybe navy (which would then be easier to figure out), you have a family, something tells me your name could possibly be catrin. Even though it isn't, your wording will definatly help a DOD polygrapher who probably checks this site figure you out quickly. It doesn't take a rocket scientist. ::)
I HOPE YOU GET CAUGHT, OR YOU FAIL!!!!!!!!
Your a disgrace to the uniform, service, and your country admittingly wanting to fail. I don't give a rats A&^ what your reasons are for. If your not qualified, your not qualified. >:( >:( >:( >:(
You realize if you fail a polygraph, your not gonna get cleared. If you lie, your then subjected to the UCMJ. Now your family is in worst shape then they were in before you took the poly.
Think clearly before you decide to become a professional BSer. Don't take the advice of cheats. Your supposedly better then that.
What did you do so horrendous, that your willing to lose your honor over?
Hey EJ, how the hec are ya? I hope I wasn't too insulting.... ::)
Good luck. I hope you choose wisely... ;)
EJohnson,
Well said, and point taken.
I appreciate you pointing out the ill perceived frailties regarding my previous post.
In response to the specific points that you raise... I respectfully disagree with your interpretation that I was providing advice that could result in the disqualification (DI) of a pre-employment or criminal polygraph testing procedure.
------------------------------------------
I wrote in my previous post:
"I strongly suggest that you carefully read the booklet, and educate yourself about polygraph testing and the methods involved."
---------------------------------------------------
In addition, I really have no idea why someone may be concerned with passing a polygraph, and honestly don't really care.
Advising someone to read a book (any book) is in no way "Obstruction of Justice." Nor, am I aiding this individual to deceive any investigative agency.
Telling the truth during a polygraph exam is certainly no guarantee of passing a polygraph exam. False positives are not uncommon, and truthful individuals are routinely denied employment opportunities as a result.

You are a DQ waiting to happen. You can choose to use the countermeasures in TLBTLD or you can choose to be honest and approach the examination with an open mind and tell the truth. Should you choose to use the countermeasures, and your opinion is "they can assume but is their word against mine" I wonder who "they" are going to believe, you or a seasoned examiner? Hope you get your act together before you take the examination. Best of luck to you

Quotewhat the hell makes you think my name is catrin? my first name is ben hence the name beezy. i am no disgrace because being dishonest about what i did when i was 15 has nothing to do with how well i can protect my country
My eldest son's name is Ben. Great name---a name of strength and integrity. I would spill the silly beans about my 15 yr old gaffs. Short of killing someone or going on a 10 day LSD bender----what could possibly motivate you to try and cheat? I personally don't trust anyone who didn't screw up as a teen. Part of your test requires you disclose that stuff to evaluate your "emotional intelligence"----which helps your employer determine that you thoroughly understand the difference between screwing up and "righting yourself" versus ignoring your development and possibly repeating history if you become distressed. The overall theme of the test will be honesty, not sanctimony. Remember the difference between a boss and a commander---and tell your story. Keep it real Ben.
Sir Beezy,
Reading the TLBTLD will cause you no harm. It worked for me and it can work for you.
The polygrapf examiners try to focuss you on little things you did
in the past and try to make them molehill mountains. Of course to fail you.
Yourself you can see now from the postings that they are angry and flustered when the non believers in polygrapf give you advice to beat the schmutzvanger machine.
Read it well and practise the countermeasures.
You will pass. You will get that job. You will be a success.
Blessings for you.

JP

Sir (JP)
Hate to rain on your parade. However, I'm not a polygrapher. You haven't read any of my previous posts. I won't deny the fact the poly's are important. However, I've got issues with members of our armed services who think it's important to lie on a polygraph to receive their clearance. Albeit our friend here probably smoked some weed prior, or other narcotic prior to enlisting into the military. With that said, he thinks he needs to lie, as not to get caught into a fraudelant enlistment. My question to Beezy is, what are you going to do after you fail your polygraph and the interrogation begins? The UCMJ albeit is similar to the civilian laws, but oh so different. Are you going to handle it?
Good Luck... Remember the truth will set you free. I'd rather be accused of lying then being accused, or caught cheating. Think wisely, you get one chance at a clearance. Don't lose it... If your not going to pass it without cheating, then whats the point of taking the exam? ;)

Of course you are assuming that TLBTLD is an ace. I wholeheartedly disagree. I think it is tragic to mistake a joker for an ace. I wager that far more good candidates with too large of an ego to admit some petty BS from teen years ruin their opportunities by virtue of bad advice---than do these alleged gentle fawns who are victims of error rates.
Beezy, let me guess----you went a period of time experimenting with a little cocaine and an occasional mushroom. Woopty do. You think good candidates don't have such sf86 adjustments at the 11th hour? Of course they do.
so can somebody please explain how biting the tongue causes a reation on their graph? what it does physically to your body to cause such a reaction?
To address your previous question, when you create pain in your body, your body responds by increasing blood pressure, increase in sweat gland activity and there will be a change in breathing.
The down side to artificial reactions, they are noticeably different from a normal reaction observed on a polygraph chart, therefore detectable as a countermeasure by a seasoned and educated examiner. We look for those types of false reactions on all charts and in opposition to posters that claim they are not detectable, they are very obvious.

Sir Johnson,
I do believe that more innocent and truthful people will pass the polygrapf test after reading the TLBTLD than if they did not.
It iss distressful that innocents and truthful people need a form of protection from the cursed test.
In Europe, some drivers use the Road Angel gps device. Statistiks prove that drivers using roadangel device are having 70% less accidents. They did not ever start their journeys to have accidents, but with protection like the roadangel they had a 70% better chance of 'passing' or not having an accident.
The TLBTLD is like the roadangel. It will give you a 70% better chance to pass the polygrapf test.

Sir,
If somebody else pricked the examinee, would the examiner be able to tell whether the pain reaction was caused by the examinee or the other person?
Do you contendt that humans experience different types of pain caused by same stimulus at same site ?
If I bite my tongeu, or prick my tongue, or my friend pricked my tongue - are you sure that you can decide from your chartings which one was the cause of the pain ?
Of course you cannot. This fable that polygrapf witches can tell the difference between psycho-pain and physical-pain reactions is the falsehood of the century. As false as Mr Martins PhD.

Why was it necessary, then, to invent and implement the anal sphincter muscle squeeze detection pad? Seems like it can't get much more artificial than that.

Thank you for your support. I was also thinking that if the examinee was over nervous during the test and passed some wind, that would probably activate the detection pad and a truthful person could be accused of cheating because of a natural emission of gas.

Don't get me wrong, JP, I was not supporting you., although if my question bolstered your argument, then perhaps that is a benefical result.
I was asking an honest question. If it is so easy for a poly examiner to tell the difference between natural reactions and artificially induced reactions, then there was no need to develop this piece of hardware, was there?
Third, you might consider implementing a natural gas emmision butt plug, that is designed to release slowly when a certain amount of pressure builds up. That way, you would not risk a false positive countermeasure detection opinion.
Lastly, don't make any assumptions as to my gender, please.

It appears we are looking for more information regarding countermeasures. Any induced reaction has some specific markers. Creating pain generally causes an exaggerated response. For one to gain the ability to use these types of countermeasures would require practice on an actual polygraph.
The use of a motion sensor "butt pad" confirms without question that you are using the anal contraction counter measure.
Camera's on the face confirm tongue biting because of muscle movement.
We could go on and on with this, however it would not be convincing to you IMHO and therefore a waste of time for all reading the posts here.
I don't respond to JP for a reason, and I do not enjoy baiting.
Sir Hunter,
You are deceiving us.
Please explain what this specific markers looks like and how is they different to normal markers.
The polygrapf is very basic equipment. It cannot read minds or make determinations. it does not know the differents between data inputs. It can only record from basic electric (digital) signals.
There is not one signal (electric current ) for a fahrt and another for pinching buttocks. There is no differents at all between input signals
for fear or pain.
There iss no additional Muscle movement of tongue biting when it is done at same time as closing the mouth after speaking.
You will not respond to me because you can not do so. You have shot past the target and missed.
The polygrapf belongs in a museum to wasted endeavors.

It appears from your remarks that one can train himself to successfully use countermeasures if they practice on a polygraph. Is this true?
You also say that "induced reactions have some specific markers". But isn't that exactly what a polygrapher is doing when he questions, inducing reactions" Perhaps you meant inducing reactions by physical means, please clarify.
So far though, you have limited yourself to commenting on physical countermeasures. What about mental countermeasures? Do these also have "specific markers"?
For example, all it takes for me to raise my pulse rate and blood pressure is to visualize standing on a high bridge (fear of heights) or getting a blood test, (fear of needles).

We know that innocent people have been wrongly accused of deception. It happens. It's not a perfect system. I'll admit to that. My beef is not about using the CM. It's how or why there using it. I've got a big problem with someone lying on there SF-86, and wanting information to deceive the investigator willingly, and knowingly. Again, if I were to take a test, and was accused of being deceptive, and have had the oppurtunity to clear my name during a post test interview, or interrogation. Such person will be relying on alot more then said squiggly lines. The machine is part of the test, I guarantee a compentent examiner is looking at the totality of the situation, before making their final determination.
Please, someone (preferrably a polygrapher) correct me again if I'm over stepping my bounderies, or if I'm wrong.

Good points nomegusto.
To clarify or extend a couple of things. Final judgments are always made using the totality of available information. Policies and standards of practice are increasingly clear about that. Also, the adjudicators about someone's job status, filing status, guilty status, are most often not the polygraph examiner. This is a reflection of the use and meaning of test data. In psychological testing, an MMPI result itself is never enough to warrant a clinical diagnosis, nor is an IQ test score enough to pronounce someone retarded. People have criticized polygraphy for both sides of the discussion - basing results on test scores, or using extrapolygraphic information - they simply want to criticize. Tests simply give information. Decisions and diagnostic opinions are made by professionals - who sometimes use test results and other information.
I know that some readers of this site would prefer to oversimplify things and reduce the matter to "squiggly lines." But people will fail to learn anything if we leave it at that. Remember. Tests simply give information. In the case of polygraph, that information pertains to how well an individual's test result fits a known model or models, for deceptive or truthful persons. For another example, take a 7th grade spelling test. What we're interested in is how well each student's test score fits our known model for 7th grade spelling scores. So, while test results are a matter of how well a persons responses fit a known model, final grades are often a matter of a lot more information than a single test.

Nopoly
One can train to defeat polygraph, however, a seasoned examiner in most cases will detect the countermeasure. I am well aware of the group on this site that constantly repeats the adage that we are unable to detect countermeasures. Regarding mental counter measures, yes SOME are detectable, others I'm not so sure about.
Regarding induced reactions, I am speaking about both mental and physical countermeasures. To what degree do you cause a reaction to occur, is that your normal? Anything out of the normal range is suspicious to me. Second part of the answer, I look at the relevant question to see if there is any reaction, should not be any of consequence, so yes it is an overall totality of the charts, not just one place on a chart that I look at. I am sure other examiners have differing opinions.
Have I ever missed when someone used countermeasures? I'm sure I have and I don't have a problem with that, it is a fact of life and I am not perfect, nor is polygraph.
