The de Bono Hats system (also known as "Six Hats" or "Six Thinking Hats") is a thinking tool for group discussion and individual thinking. Combined with the idea of parallel thinking which is associated with it, it provides a means for groups to think together more effectively, and a means to plan thinking processes in a detailed and cohesive way. The method is attributed to Dr. Edward de Bono and is the subject of his book, Six Thinking Hats.
The premise of the method is that the human brain thinks in a number of distinct ways which can be identified, deliberately accessed and hence planned for use in a structured way allowing one to develop strategies for thinking about particular issues. Dr de Bono identifies six distinct states in which the brain can be "sensitised". In each of these states the brain will identify and bring into conscious thought certain aspects of issues being considered (e.g. gut instinct, pessimistic judgment, neutral facts).
Having identified the six states that can be accessed, distinct programs can be created. These are sequences of hats which encompass and structure the thinking process toward a distinct goal. A number of these are included in the materials provided to support the franchised training of the six hats method; however it is often necessary to adapt them to suit an individual purpose. Also, programs are often "emergent", which is to say that the group might plan the first few hats then the facilitator will see what seems to be the right way to go.

Six distinct states are identified and assigned a color:
![]() | Blue Hat Thinking- Process
|
![]() | White Hat Thinking- Facts
|
![]() | Green Hat Thinking - Creativity
|
![]() | Yellow Hat Thinking- Benefits
|
![]() | Black Hat Thinking - Cautions
|
![]() | Red Hat Thinking - Feelings

Sequences always begin and end with a blue hat; the group agrees together how they will think, then they do the thinking, then they evaluate the outcomes of that thinking and what they should do next. Sequences (and indeed hats) may be used by individuals working alone or in groups.
Example programs- Initial Ideas - Blue, White, Green
- Choosing between alternatives - Blue, White, Green, Yellow, Black, Red
- Identifying Solutions - Blue, White, Black, Green
- Quick Feedback - Blue, Black, Green, White
- Strategic Planning - Blue, Yellow, Black, White
- Process Improvement - Blue, White, (Other peoples views) Yellow, Black, Green, Red
- Solving Problems - Blue, White, Green, Red, Yellow, Black
- Performance Review - Blue, Red, White, Yellow, Black, Green
