Dr. Edward de Bono developed the Six Thinking Hats method to improve thinking and decision making. It involves wearing imaginary hats that represent six different types or modes of thinking: white hat for neutral facts; yellow hat for optimism and benefits; green hat for creativity; red hat for emotions and feelings; black hat for caution and risks; and blue hat for organization and conclusions. By compartmentalizing thinking into distinct "hats," it allows a group to examine ideas from different perspectives in an orderly way to derive better decisions and solutions. The facilitator guides the discussion by calling for different hats when appropriate, while participants contribute under the hat currently in use.
