3.2The 6 Thinking Hats (De Bono)
The essentials in 30 seconds
- Separate the modes: facts, emotions, risks, benefits, ideas, steering — one mode at a time.
- Think in parallel: the whole group wears the same hat at the same time, in turn.
- Effect: more complete and calmer thinking: nothing forgotten, no personal clash.
Running case — Sara must decide without a clash
For reception, Sara's team is split: some see the risks (queue, costs), others the benefits (modernizing). Each sticks to one mode. Sara proposes the 6 hats: first all the facts (white), then feelings (red), risks (black), benefits (yellow), ideas (green) — with her in blue to steer and conclude.
Sequel to case 3.1 — Sara structures collective thinking about reception.
1. Separating modes of thought
The Six Thinking Hats (Edward de Bono) structure thinking by having everyone adopt, in turn, six distinct modes of thought, symbolized by six colored hats.
The idea: instead of mixing everything (facts, emotions, criticism, optimism) in a confused discussion, you ask everyone to think in the same mode at the same time, hat after hat.
2. The six hats
White (the facts: data, figures — neutral); Red (the emotions: feelings, intuitions, no justification); Black (caution: risks, weaknesses).
Yellow (optimism: benefits, advantages); Green (creativity: new ideas, alternatives); Blue (organization: steering, synthesis, next steps — the conductor).
3. Thinking in parallel
By collectively moving from one hat to another, you separate modes usually confused, making thinking more complete, calm and productive.
Benefits: everyone explores all angles (not just their leaning), you avoid confrontations (when all wear black, nobody blocks on principle), and no dimension is forgotten (emotions included).
The hats cloakroom (seen in a meeting)
The hat is not the head: you put it on, you take it off — nobody is their hat.
🔎 Concrete example — A hard decision without conflict
Instead of a debate where each defends an angle, you structure.
Classic debate: the optimist vs the pessimist, going in circles.
6 hats: all the facts (white), then all the risks (black), then all the benefits (yellow)… → complete, calm decision.Result: all explore each angle, without personal confrontation.
Reflex: the blue hat steers the order and synthesis.
Section vocabulary
- Six Hats (De Bono)
- A method structuring thinking into six distinct modes of thought, adopted in turn by all.
Simple example: Sara's team spends 10 min per hat on reception.
What it is not: assigning one fixed hat to each person (you are the black one).
Reflex: announce the current hat: we are in green now.
- White / Red hat
- White: objective facts (neutral); Red: emotions and intuitions (no justification).
Simple example: White: 12 min average wait; red: I fear misdirecting people.
What it is not: mixing feelings and figures in the same sentence.
Reflex: allow red in 2 min, with no debate or proof.
- Black / Yellow hat
- Black: caution (risks, weaknesses); Yellow: optimism (benefits, advantages).
Simple example: Black: cost, moved queue; yellow: shorter wait, image.
What it is not: keeping only black (it will never work) or only yellow.
Reflex: impose both: 5 risks THEN 5 benefits.
- Green / Blue hat
- Green: creativity (new ideas); Blue: organization (steering, synthesis).
Simple example: Green: ticket with callback time; blue: order, timing, decision.
What it is not: letting the session drift with no steering or conclusion.
Reflex: give blue to the facilitator: timing, order, synthesis.
- Parallel thinking
- The principle where all adopt the same mode of thought at the same time, instead of clashing.
Simple example: The whole team seeks risks together for 10 minutes.
What it is not: a debate where the optimist faces the pessimist.
Reflex: if it clashes: which hat are we wearing now?
In practice — Structuring thinking with the 6 hats
- Have the whole group adopt the same hat at once, one after the other (parallel thinking).
- Go through the modes: White (facts), Red (emotions), Black (risks), Yellow (benefits), Green (ideas).
- Use the Blue hat to steer the session (order, synthesis, next steps).
- Note the benefits: all explore each angle, fewer confrontations, no dimension forgotten.
Ready-to-say script — framing the hats session (30 s)
For reception, we will wear the same hat together, 10 minutes each: first the facts, then feelings with no debate, then risks, benefits, ideas. I keep blue: I manage time and synthesis. We start in white: what do we really know?
To say standing before a board: announce the order, the timings and the single-mode rule.
Copy-paste template — 6 hats run (60 min)
TOPIC: _______________
WHITE facts (10 min): _______________
RED feelings (5 min, no debate): _______________
BLACK risks (10 min): _______________
YELLOW benefits (10 min): _______________
GREEN ideas (15 min): _______________
BLUE synthesis + next steps (10 min): decision ___ / who ___ / when ___Small team (2-3)
30-min version: 5 min per hat, synthesis on one sheet — no formal room needed.
Remote team
One shared doc per hat, visible timer, written turn-taking for red.
Tense topic / conflict
Start with white + red to empty facts and emotions before any risks/benefits debate.
Solo
Alone: write 3 lines per hat in a row — the final blue decides the 2 next actions.
✓ Best practices
- Clearly announce the current hat so all stay in it.
- Do not forget the red hat (emotions), often neglected in meetings.
- Give the blue hat to the facilitator (order and synthesis).
✗ Common pitfalls
- Letting each keep their usual mode (back to confused debate).
- Skipping the emotions hat out of professionalism.
- Confusing the temporary role (black hat) with a personal stance.
Key takeaways
- The 6 hats have everyone adopt six modes of thought in turn, all at once.
- White (facts), Red (emotions), Black (risks), Yellow (benefits), Green (creativity), Blue (organization).
- You separate modes usually mixed: more complete and calmer thinking.
- Benefits: all explore all angles, fewer confrontations, no dimension forgotten.
48h challenge — apply tomorrow
Run 1 thirty-minute session (white → black → yellow → green + blue) on one real topic and end with 1 decision + who + when.
- I can cite the 6 hats and their use without hesitating.
- I ran (or planned) 1 sequence in separated modes.
- I got 1 written synthesis with next steps.
Frequently asked questions
Why have everyone think in the same mode at once?
It is parallel thinking. In a classic discussion, each adopts a different mode and defends it, and the group talks without listening. When the whole group seeks risks together, even the optimist sees overlooked angles — with no personal confrontation.
Do you need real colored hats?
No: the hats are a metaphor. You can practice by announcing modes (let us focus on facts). A visual support helps make the change tangible and defuses tension (it is not me being negative, it is the hat).
In a meeting, the optimist faces the pessimist and it goes in circles. What does Sara propose?
