Why User Interviews Mislead and How to Get Real Insights

Jakob Nielsen argues that users' actions rarely match what they say, a principle that remains true today. He warns that interview questions about past experiences or future predictions often yield misleading, useless answers because human memory is unreliable and users cannot accurately envision unseen features.

What Interviews Can't Do

Interviews fail to capture detailed design decisions such as button colors, menu structures, or navigation depth, and they cannot predict how users will react to features they have never seen. Relying on users to recall specific UI details or to imagine future functionalities leads to inaccurate data.

Observing users interacting with a product provides concrete evidence of their behavior, especially when feedback is collected immediately after use while the experience is still fresh in their minds.

What Interviews Can Do

When applied to scenarios that generate measurable data, interviews can effectively gauge overall attitudes, brand perception, and high‑level impressions after users have spent time with a website or service.

Combining interviews with other methods—such as user testing, agile development, and paper prototyping—creates a triangulated approach that yields richer, more reliable insights.

Pay Attention to Question Effects

Leading or pressure‑inducing questions can cause users to fabricate suggestions, so it’s crucial to ask neutral, open‑ended questions and avoid prompting users about features they haven’t experienced.

By integrating multiple research techniques and validating findings through triangulation, designers can avoid the pitfalls of single‑method reliance and achieve a fuller understanding of user needs.
