QuoteOkay, what I want to know is this: All things being equal, and if polygraphy is such an accurate and real science, can anyone explain to me how I could pass one polygraph and then fail another over the same subject?
QuoteSo, my final question is, when a professional polygraph examiner has one test positive and another examiner has one negative, what does that mean and how would polygraph "science" (I use the term very loosely here) explain away the dichotomy?
Quote from: samurai351 on Apr 18, 2008, 10:19 AMI was given a private polygraph test which indicated I was truthful. Much later on, I was given a polygraph by the state police that said I was being deceptive.
In both instances, the questions were the same and the equipment, as far as I could tell, were the same or similar.
The only real differences between the two were location (th efirst at my attorney's office, the other at the county office) and the private polygrapher I had had done this both as a state trooper and in private practice for 25 years. The state trooper who did the later polygraph had only been fully licensed to perform polygraph exams for about a year before he did mine.

From what I have read here, there are two camps; one pro and one con, black OR white. I have not read too much about gray here.
Can anyone explain to me what they believe? Surely, a person has to be either lying OR telling the truth about the same subject, right?

BTW, despite my apparent tone, I am not really trying to be facetious, but I do have an academic interest.
