Polygrapyer Manipulation

[sie]

If a respondent is capable of chart manipulation than I would imagin that a polygrapher could do the same. If so how?

If proven could one not sue for professional malpratice?

The most obvious way for a polygrapher to rig a polygraph "test" against a subject would be to sensitize the subject to the relevant questions before the "in-test" phase.

See also my message board post, Was Wen Ho Lee's FBI Polygraph 'Test' Rigged?

I suppose that a polygrapher might be liable for civil damages in the event that he falsely accuses anyone of deception, whether or not there is evidence that the "test" was deliberately rigged. I suspect that a strong argument could be made that every "Control" Question "Test" is administered under fraudulent pretenses, which may also vitiate any waiver of liability the subject may have signed. In any event, this is a matter best taken up with a lawyer in your jurisdiction.

What I'm looking for are studies or reseach on Polygraph manipulation by the examiner. Are there any available to your knowledge?

[George W. Maschke]

I am not aware of any.

I recently was issued a status of inconclusive on my third polygraph.  I had passed the previous two with no problems, I had quite alot riding on the job I was applying for which I was given the inconclusive result.  I was eventually informed that I was no longer being considered for the position due to the inconclusive result.  The difference between the previous two was that the examiner(asshole) attempted to upset me regarding a couple of issues;  This consequently distracted me causing my cycles of respiration to drop to about 8 a min, while being tested, which he said was way below normal(30).  I did this unintentionally, as I was trying to relax due to him stressing my out, which I tried not to show.  My relaxation techniques worked a little to well.  He seemed quite upset after testing my three times and not getting a conclusive result.  So don't fall prey to the examiner manipulating your emotions prior to the test.
