QuoteDon't fall into the trap, however, of thinking that every question that is modified in this manner is a "control" question. For example, suppose you are being polygraphed for employment with an agency whose stated policy is that marijuana use up to 15 times is acceptable but that any usage in excess thereof is an automatic disqualifier. If you admit having used marijuana six times, one of your relevant questions may well be, "Besides what you told me, have you ever used any illegal drugs?" The key point here is that while modifiers such as "besides" often accompany a "control" question, the mere presence of such a modifier does not guarantee that a question is a "control" question.
