Try a sample question
Halfway through a session, a participant says the prototype is "terrible". What should the moderator do?
- Tell them the final version will be better
- Stay neutral and ask what made them feel that way
- Defend the design and explain the reasoning
- End the session early
Show the answer
B. Stay neutral and ask what made them feel that way — A moderator's job is to understand, not persuade. A neutral follow-up turns a strong reaction into specific, usable findings. The real test has 20 questions like this.
