Experimenter effects are more likely to occur in which interview type?

• A. Structured
• B. Semi-structured
• C. None
• D. Unstructured

Answer: (D)

Experimenter effects happen when the researcher’s expectations or behavior influence how participants respond. In interviews, the amount of control the interviewer has over the conversation matters a lot. Unstructured interviews involve almost no fixed questions or rigid prompts, so the interviewer can vary phrasing, timing, tone, and probing based on how the interview unfolds. That flexibility makes it easier for the interviewer’s cues or expectations to shape what the participant says, introducing bias into the data. In contrast, structured interviews use a fixed script with standardized questions, which limits the interviewer’s ability to steer responses. Semi-structured interviews sit between these two extremes, offering some guidance but still allowing flexibility, so they’re less prone to interviewer bias than unstructured formats. So, the format most susceptible to experimenter effects is unstructured.
