Probing/asking follow-up questions is effective for uncovering the motivations and rationale behind certain behaviors, attitudes, and perspectives. E.g., “How does that make you feel?”, “Why do you think that is?”, or “Can you tell me more about that?”

The researchers may find themselves trying to extrapolate meaning from user quotes (rather than relying on a direct explanation from the participant) if they did not ask probing questions.
