Dear Guest,
I was absolutely ignorant of countermeasures or this website during two polygraphs.  I told the complete truth on both exams.  My first one was inconclusive and the second one I was accused of countermeasures.  I thought it was some type of "psychological stress test" to see if I would snap-out on the examiner.  The examiner was either bluffing or dead wrong in my case.  If the examiner was so sure that I was using countermeasures, why even accuse me of doing them?  Just wait till the end of the test, shake hands good bye and fail me by using the scientific measures that he has.  They need to accuse and get a confession because there is no sure fire way to prove it is countermeasures.  In my case again, the examiner was convinced that I was using them but I have appealed the decision and I am getting a third exam.  If they were that absolutely sure, why offer me another exam if they can prove that I was using countermeasures? 

I will not be using countermeasures during my third exam.  I will let them know what I now know about the polygraph and see how they handle the situation.  If you read my previous post and background in those post, it will be quite embarassing to fail me without an investigation (background check) concerning their accusations.

Regards.

You seem to ignore the possibility that Bill may be innocent and simply wanting to ensure a correct result "through a deliberate act."  Particularly if he is subject to some sort of screening exam, you and your colleagues can't guarantee him a correct result (no validity associated with polygraph screening, remember??) absent his countermeasure efforts.

Bill,

Only YOU can reveal a countermeasure effort on your part.  Neither Guest nor any polygrapher can identify them.  Because they are so relatively simple to do successfully (i.e., effectively and without detection) and as knowledge regarding their use becomes more widespread, polygraphers are left with no recourse but to blindly accuse larger and larger numbers of people regarding their use.  Remember, don't be your own worst enemy--NEVER NEVER admit to any countermeasure use you might choose to employ.

My dear Bill, make sure you do exactly as Mr. Maschke says and also make sure that when you get discovered practicing countermeasures (and you will), clearly articulate to the agent to whom you will speak what prompted you to do this so that you will understand that you failed in your quest to get the job you wanted not because of some youthful indescretion, rather because you demonstrated an incredible lack of ethics by lying and attempting to deceive the examiner through a deliberate act.  You also might want to make sure that any attorney you subsequently hire knows that GM and this web site played an integral role in causing you to lose your opportunity.  Here's hoping you do not take this route! Shame on you George!

Bill,

When applying the tongue bite as a countermeasure, one should bite one side of one's tongue. This is more easily concealed than biting the tip of the tongue.

In pre-employment polygraph examinations, some federal agencies (such as the FBI) commonly use a question about driving under the influence of alcohol as a probable-lie "control" question. However, it is conceivable that some agencies might consider this to be a relevant question. You'll have to make a judgement when the question appears in context.

I suspect that instead of "Did you tell me at least one lie today?" you are more likely to hear something along the lines of, "Have you falsely answered any of the questions on the test?" or words to that effect. This question is commonly used as a sacrifice relevant question in probable-lie "control" question "tests."

For more on recognizing "control" questions, review Chapters 3 & 4 of The Lie Behind the Lie Detector.

I have a poly coming up soon and I need to know how exactly to use the measures.  I have been polyed before, but was accused of using "control measures".  Does one bite the side of tip of the tongue?  Are these control questions: Did you lie about DWI experience??  DId you tell me at least one lie today??  I read the book, but still am unclear.  Please Help!!
