Six colored hats, one kind of thinking at a time, so a group explores an idea fully before it decides.
Most meetings mix everything at once. One person shares facts, another shoots the idea down, a third gets excited and someone else is quietly upset. Six Thinking Hats untangles those threads. Each colored hat stands for one kind of thinking, and the whole group wears the same hat at the same time.
White asks for facts. Red shares feelings and hunches. Black looks for risks. Yellow looks for value. Green generates new ideas. Blue runs the process: it sets the agenda, keeps time and sums up. Because everyone looks in the same direction together, an argument becomes a shared exploration, and no point of view gets skipped.
Use it when a group keeps arguing in circles, when one strong voice dominates, or when you need to look at a proposal from every side before you commit to it.
Everyone wears the same hat at the same time. The Blue hat usually opens and closes the session.
Choose a part of the diagram or a tab to explore each hat.
What do we know, what don't we know, and how could we find out?
How do you feel about this right now, in a word or two?
What could go wrong, and where are the weak points?
What's the value here, and who gains from it?
What else could we do, or how could we make this better?
What are we thinking about, which hat comes next, and what have we concluded?
Separating kinds of thinking sounds artificial. In practice it removes several things that make group decisions slow and painful.
In a normal debate, people defend positions and attack each other's. With the hats, everyone looks for risks together, then for benefits together. The goal shifts from winning the argument to mapping the whole situation.
The hats give people a safe way to speak. A junior colleague can raise a serious risk “under the Black hat” without seeming disloyal, and a skeptic can be asked for Yellow-hat benefits. The role takes the personal sting out of the comment.
Juggling facts, feelings, risks and new ideas all at once overloads anyone's thinking. Giving each mode its own slot lets it have full attention, which tends to produce deeper thinking in less time.
Emotions shape decisions whether we admit it or not. The Red hat brings them into the open, briefly and without the need to justify them, so they can be weighed instead of leaking into every other part of the discussion.
Name the proposal in one sentence and what you need to leave with: a decision, a shortlist or a list of fixes. Agree on the order of hats and the one rule that matters: everyone wears the same hat at the same time.
List what you know and what you don't. Separate facts from opinions and note who could fill the gaps. Resist interpreting the facts yet; that comes later.
Look for every benefit, then every risk, giving each hat the same amount of time. Write down every point. If someone slips into criticism during Yellow, the facilitator parks it for Black.
Generate alternatives and new ideas, starting with fixes for the biggest Black-hat risks. No judging here: quantity and variety come first.
Go around the room. Each person gives a gut reaction in a few words. No explanations and no debate. Feelings that surface now often reveal what the logic missed.
Sum up what each hat produced, make or record the decision and agree on next steps. The order used here suits judging a proposal; change it to fit your purpose.
Six colored cards or a slide listing the hats, a timer, a whiteboard with a column per hat and someone to wear the Blue hat. With AI, the prompt below can play facilitator.
Proposal: replace paper intake forms with tablets at a family health clinic. Goal: faster check-in and fewer data-entry errors. Constraint: many older patients; a front-desk team of four.
Check-in averages nine minutes, and one form in five needs a call back to fix an error. Unknown: how many patients have used a tablet before.
Answers flow straight into the patient record with no retyping. Forms could switch to Spanish or Vietnamese with one tap.
Older or low-vision patients may struggle. Tablets need cleaning between patients, and a Wi-Fi outage would stall the whole front desk.
Text patients a form link two days before the visit, keep paper as an option, and train a volunteer “tablet buddy” for the morning rush.
Front desk: hopeful but nervous. One nurse: “I worry we'll lose the chat that happens at the desk.” The patient advisor: curious.
Run a six-week pilot on weekday mornings, with paper still available, and measure check-in time, errors and how comfortable patients feel.
The team arrived split between “great idea” and “not for our patients”. They left with a pilot designed around the Black-hat risks, and the nurse's Red-hat worry became a design goal: every patient still gets a human greeting at the desk.
AI is good at holding one mode of thinking on demand. It can stay purely cautious, purely optimistic or purely inventive without getting defensive, and it can voice hats your group finds hard to wear, such as a patient's Red hat. It can't read your team's mood or know your history, so you keep the Blue hat.
Ask for a single hat so the AI can't slide into a balanced but bland answer.
Black hat only: give me the 5 biggest risks of moving our intake forms to tablets. No upsides.
Have AI voice the gut reactions of people who aren't at the table, then check with real ones.
Wear the Red hat as a 78-year-old patient, then as a receptionist. One honest sentence each.
Turn every risk the Black hat found into a design challenge for the Green hat.
For each Black-hat risk on our list, give me two Green-hat ideas that would reduce it.
Use the White hat to list what you'd need to know before deciding, and where to find it.
White hat: what facts would we need to decide this, which do we have, and how could we get the rest?
Describe your proposal, pick a mode, then copy the prompt into Claude, ChatGPT, Gemini or Copilot. In coach mode the AI wears the Blue hat: it takes you through one hat at a time and waits for your thinking before adding its own.
The “Open in” links put the prompt in the web address. If your challenge includes anything sensitive, copy and paste instead.
After the session, click one to copy it, then paste it into the same chat.
