Unstructured interviews are a type of qualitative research method where the interviewer has the flexibility to ask open-ended questions. Unlike structured interviews, which follow a strict format, unstructured interviews allow for a more conversational approach. This can lead to deeper insights as participants can express their thoughts and feelings in their own words. These interviews are often used in fields like psychology, sociology, and market research to gather rich, detailed information. The lack of a predetermined set of questions enables the interviewer to explore topics that may arise during the conversation, making it a valuable tool for understanding complex issues.
