The document discusses different thinking "hats" or roles that can be taken during brainstorming and creativity sessions. The green hat was found to be the most comfortable for generating new ideas. The black hat, meant for cautious judgement, was the hardest to separate from making evaluations. Wearing different hats was seen as a useful tool to help break out of normal patterns and find new directions for ideas. The roles can overlap and change frequently within a group or individual.
