Definition: A reverse question is a response where a question is answered with another question. It deflects attention back to the person who asked, often when the responder lacks information, doesn't want to commit, or wants to hear others' views first.
So what? Reverse questions can help someone regain control of a conversation, for example when a tester feels interrogated. Used repeatedly, though, they can seem evasive or confrontational and cause frustration on both sides.
Examples: Responding to "What browsers should we support?" with "What browsers are most popular in our user analytics?" A tester answering a pointed question with a question when they feel under attack in a meeting.
