I just took a poly recently that was quite different then what I expected. The polygrapher and I chatted for a bit about the area we are both from and the politics of the small city. We both seem to agree on quite a few things and we got along quite well. After that, he went over the questionaire which had approx. 6 parts(sex, work history, crime, phq, drugs, and credit). He then attached all the instruments to me and began the questions(7 total questions) which were quite simple. The first question was "Is your last name XXX?". The other six questions were "Did you lie in section 1(sex)?" and so on until the last question. After that he told me I was done and said I did very well and that was it. Is the first question where he asked me for my last name the control question? What do you make of this test? Thanks guys.
