DIorNDI,
I told the truth and DIDN'T pass my polygraph. So, while the fact that you told the truth and did pass does not indicate that it's just you, the fact that I along with many others told the truth and didn't pass indicates that it's also not "just me."
I see one major flaw in your analogy of polygraph examiners/polygraphy to medical doctors/the practice of medicine: in each of your examples, you fail to mention one thing. These victims (or their families) of malpractice all have some type of recourse available to them. Whether it be corrective surgery without charge to the more serious cases involving civil litigation, these people may suffer greatly and experience long-term trauma but in the end they have RECOURSE.
Indicate to us all what recourse a truly "honest" person found deceptive through a polygraph "test" has. The opportunity to vehemently deny the implied or explicit accusations of deception? And then what? In the case of pre-employment screening, nothing. Some are lucky enough to get a retest. Many are not. Many are then, as a result, precluded from employment by other agencies. And again, what chance do they have to provide a reasonable defense?
Those of "us" in the "victim by false positive" group have in many cases experienced significant trauma by committing to a process that one truly believes will result in the acheivement of a long sought after goal only to be denied this acheivement based on the opinion of one examiner operating a machine designed around an undeniably flawed, pseudoscientific theory that deception can ACCURATELY be detected by monitoring physiological response. I imagine you are thinking at this point something similar to "mellodramatic BS, you don't get the job, so what?" I invite you to ATTEMPT to imagine yourself being falsely accused of deception and then denied not only employment but the fulfillment of a goal and honestly admit that you would not be feeling the same way as many others do. The comparison of losing life or limb to being denied employment does seem somewhat drastic. But remember, you are the one who drew the initial comparison.
Your analogy fails relative to what this site strives to accomplish. The polygraph exam, when used as a pre-employment screening tool, is an unfair, invalid and dangerous method used strictly to "sift" through otherwise qualified candidates in an effort to save the money that would have been used in a costly background investigation. In fact, you are quite mistaken that a failed polygraph result is not used as a sole disqualifier. Take the FBI, for example. Upon the submission and approval of the polygrapher's opinion that a candidate "failed" the polygraph exam, that candidate is issued a letter rescinding the conditional employment offer within ten days. That candidate is typically not contacted before this occurs for an explanation and a background investigation DOES NOT occur. So, you are in fact completely wrong in that the polygraph does not represent a disqualifer in itself.
Further, and again using the FBI as an example, the polygraph was not reinstated for pre-employment screening purposes until 1994. Coincidentally, prior to 1994 the FBI also held a "zero-tolerance" drug policy that resulted in immediate disqualification should an indication that a candidate had used drugs be discovered during a background investigation. That's right, background investigation. You ask, how does any given agency determine if what an applicant says is true? Your answer is through an in-depth background investigation. It seems that it worked before, doesn't it? Equally coincidental, upon adopting the polygraph as a phase of the applicant process, the FBI also eliminated its "zero-tolerance" drug policy with the realization that it is an unrealistic expectation. And yes, FBI representatives have stated that as being the reason for the new policy:
