What type of questioning is central to the art of interrogation?

Open-ended questions are central to the art of interrogation because they allow the subject to provide detailed responses without being led in a particular direction. This type of questioning encourages deeper engagement and facilitates the flow of information. When an interrogator asks open-ended questions, the subject is prompted to share their thoughts, feelings, and experiences, which can often lead to more revealing and spontaneous responses.

In contrast, leading questions can restrict a person's answers and suggest a specific response, which may not elicit authentic information. Rhetorical questions do not require an answer and can detract from a productive dialogue, while aggressive questions may create defensiveness in the subject, hindering the chances of obtaining valuable insights. By focusing on open-ended questions, interrogators can build rapport and gather a more comprehensive understanding of the situation at hand.
