Good day, all; I took a CVSA exam today, as required, in the hiring process for a local public safety agency. I have *always* seen the "lie detector machines" as a complete load of crap...and as an aside, I am absolutely amazed at how ferociously these polygraph/VSA examiners defend their precious machines and occupations. I totally agree that they MAY help to get confessions or admissions from truly ignorant people, but to rely on the ability of these machines to discern the truth from lies in any person is asinine. So, stepping off my soapbox, I'd like to describe what happened today, and to hear what opinions anyone would like to offer. I sat down with a "background investigator" (a detective for the local P.D.) to go over some documents and my pre-employment questionnaire. After spending 15-20 minutes with him, I was turned over to another detective who was to administer my CVSA. The second detective was very, VERY talkative and pleasant (he also prompted me to speak many times), and I almost had the impression that the "machine" was being calibrated as I spoke. Unless he had a foot operated lever, though, I saw no way for him to be isolating my voice/responses from his own voice. After 5 minutes or so of pleasantries and describing how the machine worked, he went over the questions. He stated there were only four "relevant" questions, four "irrelevant" questions, and two "control" questions. He didn't use the word "control", but stated that he wanted me to lie when asked these two questions. The relevant questions to the best of my memory: have I stolen anything over $50 in value from an employer, had I committed an undetected crime that would DQ me from the position, had I used illegal drugs in the last two years, and had I purposefully omitted info from my application. I don't remember all the other questions, but he asked me to lie about if the lights in the room were on, and if he had a mustache. He explained that occasionally he might hit the "trigger" button for the CVSA detector either too early or too late to capture my response, and would have to back up and repeat the question. This sounded like crap to me; to be that uncoordinated in a slow, deliberate interview seemed very unlikely. We went through a practice run of it first. Then, we went through the entire series of "yes" or "no" questions three separate times. On a couple of questions, as warned, he had to "back up" and repeat a question. I honestly can't recall if it was for the same question on all three runs, or on at least two of the runs. After each run, he took about 2 minutes to click and point and review the results. After the third cycle, he said that we were finished and that their Human Resources Dept. would be in touch with me. I didn't ask any questions so as not to raise suspicions. I know from reading other posts that the lack of a post-test interview was a good sign. This just seemed way too quick (although I'm used to the polygraph sessions from taking a couple of them), and the fact that he asked NOTHING about any of my responses reallllllly made me a bit nervous on the drive home. Given the less-accuracy-than-a-coin-toss probability rate for these machines, I would expect to have been asked about at least ONE of my responses. Am I reading too much into this and being paranoid, or did I crash and burn so badly that it wasn't worth asking me about?? Thanks for reading, and George and Gino...more power to you, soldiers! I'm glad someone has really taken these..."sciences"...to task.
