Information does not affect the validity of a comparison question test

So, assuming you are, if this is the best you have, then you are in big trouble, as this "study" is so poorly constructed and administered that it lacks any scientific validity.  For example, the most important variable, (whether or not a student read Georges book TLBLD), is not even verified or verifyable.  Just a student's word that the did or did not read it.  Further, whether or not they actually used any of the techinques in the book are also unverfiable.

But, lets for a moment assume that what you postulate is in fact true, that counter measures don't work.  Poly examiners should be estatic then, because what an easy way to identify and weed out the liars.  Afterall, isn't someone who might employ counter measures the exact person you are trying to eliminate from police employment?  The cheater?

Lastly though, your argument falls apart completely regarding catching countermeasure users, because by virtue of the nature of the anecdotal evidence, you have acutally no idea which of the polygraph takers use countermeasures and "pass" because they "pass" and are not questioned.

So you are saying that you do not perceive any difference between the two?  I find that difficult to believe as well.

When I say that I told the truth during a polygraph exam and was incorrectly labeled a liar, there is no missing information.  The same cannot be said in your example.

In order to determine the worth of the anecdotal evidence I presented you would need to know if the subject was truthful, and if the examiner was able to determine that.  Both of those pieces of information are present, which makes that particular anecdotal evidence legitimate.  Presenting that anecdotal evidence to support my belief that the polygraph is inaccurate is completely reasonable.

In your example, you are clearly missing vital components of the situation, which render your anecdotal evidence worthless.  Your story that examiners have sometimes accused people of countermeasures, and sometimes those people have subsequently confessed is missing the necessary information one would need to determine its legitimacy.

As previously mentioned, in order to determine if your anecdotal evidence was valid, one would need to know the number of people being tested, the number who were accused of using countermeasures, and the number of people who actually were using countermeasures.  You have provided none of that information; therefore, presenting that anecdotal evidence to support your belief that countermeasures are detectable is neither reasonable nor accurate.

The most recent study is cited somewhere on this site, and you can also see the writings of Drs. Honts and Rovner.

You'll see Dr. Honts' older studies cited here without the caveats Dr. Honts adds, and you'll fail to see his more recent statements clarifying his findings for those who read more into them than they should.  In short, it's his position, based on research, that CMs are not a real fear for the average examiner.

Quote:


Maybe that's your conscience.  Look closely and you'll see I didn't.  I set you up to strike down my anecdotal evidence so that I could point out you do the same thing all the time.  Can you say "double standard"?

Barry_C wrote on Dec 4^th, 2007 at 8:38pm:


Mr. C, what research are you speaking of, specifically, and where can one read the write-ups?

Barry_C wrote on Dec 5^th, 2007 at 4:55pm:


I have a difficult time believing you misconstrued my post in such a manner. 

What other posts could we go through, select a few words, take them out of context, and pretend to make a point with?  I’m sure there would be a bunch.  What would be the point of doing so?

You were claiming that since polygraph examiners sometimes accuse people of using countermeasures, and sometimes those people subsequently confess, that shows examiners are able to detect countermeasures.  You are citing anecdotal evidence that is, in and of itself, incomplete.  What would be necessary for an accurate idea of how well or poorly examiners can detect countermeasures is the number of times an examiner believes he or she has detected countermeasures, compared to the actual number of times countermeasures were used.

If an examiner believes they detect countermeasure usage in one hundred test subjects out of five hundred subjects being tested, and all one hundred of the accused subjects confess to actually using countermeasures, AND none of the other four hundred test subjects were using countermeasures, that would prove that countermeasures are detectable.

All you cited was incomplete anecdotal evidence consisting of stories told by examiners, relating how they accused someone of using countermeasures and that person admitted to doing so.  There was no information on how many of their test subjects they have incorrectly accused of using countermeasures, and no information on how many of their subjects were actually using countermeasures.

My comment about such anecdotal evidence not being particularly informative was on point and correct.

If you stick to that one, you'll never have anything to say again, which was my point.  You use anecdotal "evidence" all the time when expedient for you.

Barry_C wrote on Dec 4^th, 2007 at 8:38pm:


Using anecdotal evidence of people being accused of and confessing to countermeasure usage is not particularly informative.  There's a lot of information being left out.

How many people are accused of CM's that do not subsequently confess?  How many of those were actually using CM's, and how many were not?

If you polygraph one hundred people, accuse fifty of them of using countermeasures and five of them admit to it, that's hardly proof that countermeasures are detectable.

Quote:


George, I believe Eric and others here have (time and again) told you they catch people (who confess to CMs).  That may not be the type of evidence for which you are looking, but it still makes the point to some extent.  Is it scientific, no, but you guys use that logic here all the time.  The "I failed so polygraph doesn't work" argument.  (For those being intellectually honest, the flip side is that they could call everybody CM users, some of whom confess, and they use that to make their claims.  I don't believe that to be the case, but we'll never get anywhere with this one.)

I've participated in courses in which we had to identify CMs in charts, some of which didn't contain any.  I can tell you people found many them (perhaps not all), but time and time again, they had no effect on a DI score, so the current research (which validates Dr. Rovner's) is not a surprise to those of us in the polygraph community.

I don't suspect it will be long before you have the concrete evidence you are looking for, but we'll have to wait a little bit on that one.  In the meantime, the research we have shows they don't work, and there's a real fear that they will cause a truthful person to fail.

nomegusto,

There is no evidence that actually using polygraph countermeasures increases the risk of being accused of using them, or that not using them reduces the risk thereof. In my own experience, I was angrily (but falsely) accused of using polygraph countermeasures by one of the LAPD's most experienced polygraph operators. At the time, I did not even know what polygraph countermeasures are. I've heard from numerous individuals who have had similar experiences.

Barry_C wrote on Dec 3^rd, 2007 at 11:08pm:


Barry,

If my statement that the polygraph community has no demonstrated ability to detect countermeasures is untrue, could you tell me who in the polygraph community has demonstrated such an ability? Where and when?

If the polygraph community wants the public to believe that it can detect polygraph countermeasures, then some showing of such ability is in order. It's not a question of "appeasing" me. As things now stand, the points I raised in my 2001 critique, "On the Esoteric Wisdom of the Polygraph Sages: Whereby Countermeasures Are Revealed through the Mystic Art of Polygraph Chartgazing," remain pertinent today.

How did breathing turn into urinalysis, or thinking poetry? 


Either way. If you get caught and your trying to get a job. Your chances of getting a job went from good to nonexistant...

EJohnson wrote on Dec 3^rd, 2007 at 3:27pm:

That's a very poor analogy.  If I agree to submit to a urine test I would have to give a urine sample.  If the person doing the testing also specified how I was to breathe and what I was to think about while I was urinating, I would have serious doubts about the validity of the test.  As would any reasonable person.  As long as I give the urine sample I am fulfilling my part of the test.  What I think about while I'm doing it is irrelevant.

If I agree to submit to a polygraph exam it is incumbent upon me to tell the truth, as it would be to any ethical person.  If I choose to recite poetry in my head or do long division in my head after each truthful answer, how is that behaving unethically?

I already know from experience that simply telling the truth is no guarantee of passing the polygraph.  If the test was accurate, it could determine truth or deception.   

Labeling me as "purposefully noncompliant" for what I am thinking?  That sure sounds like a guess to me.  Unless polygraph examiners have developed the ability to read minds.  And, if they did, they'd be able to determine that I was telling the truth, regardless of what I was thinking after the question...

That's not true.  Perhaps it hasn't been done to your satisfaction, but who are you that we need to appease you?  Examiners here have told you that they catch them all the time.  We are poor at it according to the research, but that same research shows it doesn't matter.  The deceptive are still found deceptive.  The truthful, on the other hand, may well skew things in the wrong direction.

Happy Monday everyone. Hope we all had a great weekend. I wish I could figure out how to use the cute little quotes. LOL...

Here we go....

Beezy's original question was does holding your breath DURING a control question help as a counter measure? I stated the obvious. Thats it, and hope he takes the advice of chilling out before the test, and he'll pass. 

Sarge:
Good seeing you again. If the subject is controling his breath consciously, and caught with no decent explanation why, then yeah I believe such person is purposly trying to alter the results of the test. However there is an exception. For example: You have members who've done swat, or special missions. In their training, there conditioned to use tactical breathing (combat breathing) when there in a stressful enviorement. The key word is that their conditioned for it. It's now subconcious. If they can explain the validy of what there doing, documentation etc etc. I don't think it'll count against them. I know, because this has happened to me. It was brought to my attention I was changing or trying to manipulate my breathing. I explained my actions, and we continued on with the tests...


Again, forget about the pros/cons of CM's. Because again the tester (especially if he/she is leo) will be looking for those danged NVI's. You can beat a machine, I'll agree to that. But you can't beat your subconcious... I think were foolish if anyone believes the only thing a polygrapher is looking at is a chart. I guarantee there looking at the examinee at the same time...

Poor analogy. Urinalysis tests are based on sound science. Polygraph "tests" are not. Drew Richardson explained the difference in his discussion of scientific control and polygraphy during his presentation to the National Academy of Sciences' Committee to Review the Scientific Evidence on the Polygraph:

Next time I am required to give a urine sample for analysis----you know, the sort of test that rarely but on occasion does give false readings if a person likes poppy seed bagels (yummy), I will hold my bladder---because under Sarge's reasoning, it is nobody's business what I do with my urinary track.  

p.s. Whether you are holding back urine or breath, it is "purposeful non-compliance" and the report will be labeled as such. Such a label taints people with a stink that stays around for a while.

nomegusto wrote on Dec 2^nd, 2007 at 11:56pm:

Do you also believe that someone, unlike the original poster, who tells the truth on every answer during a polygraph exam but also consciously controls his breathing is "cheating"?

I think that a person's ethical responsibility is fulfilled if they are answering all the questions truthfully and not withholding any information.  If I choose to do math problems in my head it is nobody's business but mine.

nomegusto wrote on Dec 2^nd, 2007 at 11:18pm:


nomegusto,

You are dead wrong about breath-holding (after exhalation) not being a polygraph countermeasure. Referred to as "suppression" in the polygraph literature, it is perhaps the single most common scorable breathing reaction. Of course, to be effective as a countermeasure, it must be done timely with the control questions. See Chapter 4 of The Lie Behind the Lie Detector for more on this and other polygraph countermeasures.

beezy,

Although ready countermeasures to the polygraph are available, the polygraph community has no demonstrated ability to detect them, and truthful examinees might wisely choose to employ countermeasures to protect against the serious risk of a false positive outcome, applicants for positions of public trust have an ethical obligation to answer relevant questions truthfully.

I've NEVER used a CM during a polygraph. I've told the truth in every test I participated in. I'm NOT a polygrapher. 
So, your gonna stop breathing, or cause yourself pain? For what??? Not worth it. Some will say they passed. 
What did you do that was so bad? Was this before you were 18? How old are you now? Are you trying to become a law enforcement officer? Most pro polygraph guys/gals will tell you that they can detect counter measures, while the anti guys/gals say that they cant detect it. Honestly if your trying to get a job is it WORTH the chance of maybe getting caught. 
I've said it before, and I'll say it again. I'd rather someone accuse me of lying instead of proving me a cheater.

bro think about this. be honest about the stuff you did younger. if you lie, and are luckily enough to pass, and they find info about you during a BI your screwed... Ya gotta step up and be honest. how do you expect to be in a position of trust if you lie to get to that position... if you don't meet the requirements. look for a different profession...

altho that is a sign of cm will that help me pass if they dont detect it?  does biting the tongue actually work.  when should i bite my tongue during the actual control questions, before or after the control questions?

for a job but the thing is i used to do alot of illegal stuff when i was younger i never got caught.  now that i am older and i regret the stuff i did as a youth it will effect me getting the  job.

Ok bro...
Holding your breath is a clear sign of CM's. 
I don't advocate the usage of CM's. However I do advocate you going to the test prepared. The information on this site will tell you step by step of what to prepare for.
Why are you going to be tested for?

i mean holding my breath during the control questions and then start breathing again normally after i answer?  cuz i dont fully understand the control breathing.  i might be too nervous and start breathing erractically
