This document discusses the Thinking Hats technique for structured group discussions. It describes how Thinking Hats allows a discussion to consider different viewpoints by assigning each participant a role or "hat" such as logical, factual, cautious, emotional, or out of the box. Participants discuss an issue from the perspective of their assigned hat. This structures the conversation and avoids open debates, instead creating a meaningful discussion that considers all angles of an issue. The document provides instructions for how to implement Thinking Hats in a group.
