Homer,

It seems likely that the outcome of your polygraph interrogation was indeed "inconclusive," otherwise, you probably would not have been invited back for a second polygraph session.

The question, "Other than what you've told me, have you ever committed a crime?" seems very likely to be a "control" question because of its vagueness. If your polygrapher grilled you on this question between polygraph charts, he may have actually been trying to help you "pass" by sensitizing you to this "control" question, thus increasing the liklihood that you would produce a significant physiological response when asked it.

On the other hand, the question about having ever committed "a crime" could be used (however inappropriately) as a relevant question. Without knowing all the questions that you were asked, I couldn't say with complete confidence that this question was intended as a "control" question. Then again, your polygrapher's vagueness about what he thought was "a crime" seems to be a good indication that he was indeed using it as a "control" question.

If you haven't done so already, I suggest that you download the PDF version of The Lie Behind the Lie Detector, print it out, and read chapters 3 & 4 carefully. I wish you well. If you have any further questions, don't hesitate to post them here. In addition, when it's all over, feel free to share your polygraph experience with others in the new "Share Your Polygraph Experience" forum at:

Homer,

Yes, I think that the polygrapher's determination on your first polygraph interrogation was probably "inconclusive." Had you "failed," you would have in all liklihood not been invited to sit for another polygraph interrogation.

Based on the questions you listed, I'm not quite sure if your polygrapher used a probable-lie "control" question "test" (CQT) format or a relevant/irrelevant technique (also known as a "General Question Test" or GQT) with hidden "control" questions. The CQT format typically has one "control" question for every relevant question, with some irrelevant questions mixed in. Regarding the GQT format, which is not discussed in 1st edition of The Lie Behind the Lie Detector, see the following post to this message board:

After comparing this format with the probable-lie "control" question "test" format described in Ch. 3 of The Lie Behind the Lie Detector, you should be in a better position to judge which format your polygrapher used. Again, if you have any further questions, don't hesitate to ask.
