it was a voice analyses test, not a normal polygraph test. they said i should ask the questions so that he has to talk himself as much as possible. then the system analyses the pitches and emotions in the voice to an extend that the system also understands when a person is hiding something.
before i did this test, i had called the fbi (the number i found online) and asked them, which test is the most accurate one of all of them. they told me about this test and thats why i went for this one.
if the test person answers only yes or no in the test, the answer cannot be evaluated as well as when the person makes one or more sentences when answering.
everything is always okay in the end, if it's not, then it's not the end
