Investigate Whether a Prototype Task Is Neutral

Task investigation asks whether a study measures the prototype or the wording of the prompt. Read the task and observe a pilot, then compare the path participants choose with the intended interaction. Keep the task neutral enough to reveal a mental model and specific enough to support analysis.

Build a useful investigation brief

  1. Audit the wording

    Underline interface labels, step order, success hints, and assumptions about prior knowledge. Replace them with the participant goal and context. Record what information the facilitator would still need to provide for consent or safety.

  2. Observe an independent attempt

    Run the task with the facilitator silent except for the planned neutral probes. Capture first action, search strategy, hesitation, recovery, and explanation. Compare the participant path with the script without grading the person.

  3. Test alternative prompts

    Try a revised scenario or a different starting state and compare behavior. Ask whether prototype fidelity, participant familiarity, or task stakes explain the difference. Preserve the original task and pilot result so the change is auditable.

What to carry forward

The investigation brief should link task wording, prototype state, independent behavior, revised prompt, and competing explanations. End with a neutral task or a specific pilot question. Do not attribute a smooth path to the design when the instructions supplied the route.
