The Six Thinking Hats method was created by Dr. Edward de Bono in 1985 to structure group thinking. It assigns six different colored hats to represent six different perspectives or thinking styles: blue for control, white for facts, black for caution, yellow for optimism, green for creativity, and red for feelings. Group members metaphorically switch hats to explore an issue from different angles. For example, when choosing between alternatives the sequence would be blue, white, green, yellow, black, red, and blue again. Using this structured approach reduces meeting times, makes discussions more productive, and improves decision making quality.
