Three types of questions are asked. The first are irrelevant questions. These are questions that are thrown in there to help measure responses. These may be simple, such as, ”Are you from the United States?”
The second type of question is a diagnostic question. This may be something that makes you feel guilty, but has nothing to do with the investigation. This may be something like, ”Have you ever told a lie so as no not get in trouble?”
The third type are relevant questions that have to do with what the questioner actually wants to know.
These questions are all mixed together and measured against each other to detect whether or not someone may be lying.
