Which techniques promote reliable information and minimize bias in interviews?

• A. Open-ended questions, neutral language, gradual escalation, active listening, verbatim documentation, and avoiding leading questions.
• B. Closed-ended questions only.
• C. Leading questions to guide answers.
• D. Rushed questioning.

Answer: (A)

Promoting reliable information and minimizing bias comes from using interviewing techniques that encourage open responses, control the interviewer’s influence, and capture what is heard without distortion. Open-ended questions invite detail and nuance rather than limiting the respondent to predefined options, which helps reveal the truth of what happened. Using neutral language prevents loaded or suggestive wording from shaping responses. Gradual escalation starts with easier, non-threatening topics to build rapport and reduce anxiety, then moves into more sensitive areas, which helps prevent reactionary answers. Active listening ensures you understand and record meaning accurately, avoiding misinterpretation or assumptions. Verbatim documentation preserves the exact words and phrasing, reducing memory bias and later misrepresentation. Avoiding leading questions is crucial because any hint of a preferred answer can steer the respondent and contaminate the information collected.

Relying exclusively on closed-ended questions limits responses to fixed options, which can mask important details and increase the chance of missing relevant information. Leading questions introduce bias by suggesting a desired answer, contaminating the respondent’s recollection or view. Rushed questioning can overwhelm the interviewee, resulting in incomplete or thoughtless responses and higher chances of missing crucial facts.
