Methodological Foundations of Questioning Techniques

Structural Parallels

The interrogation techniques used by criminal investigators and the interview methodology in UX research show remarkable structural similarities. Both disciplines utilize open-ended questions that encourage detailed storytelling while capturing chronological and contextual information.

Key Question Patterns

The analysis reveals recurring question patterns that are successfully employed in both fields:

  • Exploration of relationships and interactions

  • Capturing temporal sequences and frequencies

  • Identification of key moments and critical incidents

  • Contextual placement of actions

  • Uncovering additional, previously unmentioned aspects

Practical Application in UX Research

Adapted Questioning Techniques

Criminal interrogation methodology can be effectively transferred to the UX context. Examples include:

  • "Were there any other apps you used?" (analogous to relationship exploration)

  • "When was the last time you used the app?" (temporal placement)

  • "Where were you when you used the app yesterday?" (context determination)

The "Reaching the Door Question"

A particularly important technique is the final open question: "Is there anything else you'd like to share with us that we haven't discussed yet?" This method enables the capture of previously undiscovered aspects and provides space for the interviewee's own impulses.

Research Practice Implications

The methodological parallel between criminal interrogation and UX research highlights the central role of the interviewer as an "investigator." As in criminology, the success of the investigation depends significantly on the quality of the conversation management. This insight emphasizes the importance of professional interview techniques for successful user research projects.

This approach not only enhances the depth and quality of user insights but also demonstrates how interdisciplinary methodological transfer can enrich research practices in user experience design. Understanding these parallels can help researchers develop more effective interview strategies and obtain richer, more meaningful data from their research participants.
