What approach to questioning allows for an in-depth exploration of a topic?

The approach that allows for an in-depth exploration of a topic is the use of open-ended questions. Open-ended questions encourage the respondent to provide more detailed responses rather than simply giving a 'yes' or 'no' answer or a brief comment. This type of questioning facilitates a richer dialogue, enabling the interrogator to delve deeper into the subject matter.

By asking open-ended questions, the interviewer invites the individual to share their thoughts, feelings, and experiences in their own words, which can lead to valuable insights, clarifications, and a broader understanding of the issue at hand. This method not only promotes a more conversational tone but also makes the respondent feel more comfortable sharing information, thereby enhancing the effectiveness of the interview process.

On the other hand, closed questions limit responses to specific answers, which can curb the depth of information gathered. Coerced questions can lead to unreliable answers, as they may involve pressure or manipulation. Direct questions may be straightforward but often do not facilitate the same level of exploration and elaboration as open-ended questions.
