Study Design

Within vs. Between DesignChoose a single group, where every twin sees every version, or a parallel study, where each twin sees only one — and when to use which.

Question FlowPlan question order deliberately — twins see earlier questions and answers, and these influence the responses that follow.

Scenarios & ContextGive twins context up front to test specific situations — the more precise the setting, the more realistic the reaction.

Question Design: Do's & Don'tsGive AI twins a clear decision space — define scales and answer formats fully, and avoid double-barreled, mixed-level and loaded questions.

Question Design: Matrix QuestionsWrite a matrix as a framing sentence, one statement per line and one fully labelled scale — Elaiia asks each row as its own question.

Eye TrackingSimulated eye tracking shows where attention goes on a visual — what it measures, how it differs from asking for opinions, and how to use both together.
