This document discusses different types of questions and effective questioning techniques. It outlines closed, open, leading, and loaded questions. Open questions are most effective for eliciting creativity and ideas as they do not contain the answer or put pressure on the respondent. Leading and loaded questions should be avoided. Facilitative questioning through the use of open questions and follow ups is important for productive meetings. Poor questioning can close down discussion, so questions should not be confusing, multi-part, or hide opinions. The "magic question" is one that unlocks new insights.
