The use of control questions is a common practice in polygraph testing. The purpose of control questions is to establish a baseline for a subject's physiological responses, which can then be compared to their responses to target questions (such as "Did you rob the First National Bank?"). Control questions are designed to elicit a slight emotional response from both innocent and guilty suspects, allowing the examiner to distinguish between the two based on the difference in response to target questions.
