Six Thinking Hats | Katharyne Shelton

// description

Six Thinking Hats assigns six metaphorical colored hats to six distinct modes of thinking: White (data and facts), Red (emotions and intuition), Black (caution and risk), Yellow (optimism and benefits), Green (creative alternatives), and Blue (process management). A group works through a problem by collectively wearing one hat at a time, which prevents the typical meeting dynamic where one person argues logic while another argues from gut feeling. By separating the modes, each gets full attention.

// history

Edward de Bono, a Maltese physician and psychologist, introduced the method in his 1985 book of the same name. De Bono had spent two decades studying thinking as a skill that could be taught, and the Six Hats became one of the most commercially successful tools in his broader body of work on lateral and parallel thinking. Corporations including IBM, Prudential, and DuPont adopted the method for strategic planning sessions.

// example

A small team deciding whether to expand their print-on-demand t-shirt brand into home decor works through each hat. Under the White Hat, they pull sales data showing their top ten designs and note that pillow and mug mockups already get high engagement on Pinterest. Under the Red Hat, the founder admits she is nervous about customer service for fragile items. The Black Hat identifies shipping breakage rates for ceramic mugs. The Yellow Hat highlights higher margins on home goods. The Green Hat generates ideas like offering fabric wall hangings instead of ceramics, sidestepping the breakage problem entirely. The Blue Hat sets a two-week test.

// katharyne's take

This one is brilliant for solo creators who tend to get stuck in one mode of thinking — usually either pure enthusiasm (Yellow Hat all day) or pure anxiety (Black Hat dominating everything). I use a simplified version when evaluating a new KDP niche: I give myself five minutes per hat and write notes for each. The Green Hat pass alone usually produces at least two product angle ideas I hadn't considered. It's also a great framework to teach if you're running a creator community — it gets people out of their default thinking styles.

// creative uses

Run a solo Six Hats session on a new Etsy product before you build it — 5 minutes per hat in a notes doc. The Red Hat (your gut fear about it) and Black Hat (concrete risks) together reveal whether you're hesitating for good reason or just anxiety.
Use the Green Hat specifically as a Midjourney style-generation session: give yourself 5 minutes to list every visual direction you haven't tried yet, with zero filtering. Green Hat is explicitly a judgment-free zone.
When pricing a new digital product or course, put on the White Hat first (what do comparable products actually sell for?) and the Yellow Hat second (what premium could specialization justify?) before you touch the Black Hat at all.

// quick actions

Pick a product decision you've been sitting on and write one sentence per hat right now — 6 sentences total. You'll notice which hat you've been stuck inside and which ones you've completely ignored.
Create a simple Six Hats template in Notion or a Google Doc with one section per hat color. Use it as a pre-launch checklist for every new KDP title or Etsy listing — fill in White Hat (data) and Black Hat (risks) before you publish.
In your next creator community call or mastermind, assign a hat to each participant before discussing a group decision. The person wearing the Black Hat has permission — and responsibility — to voice every concern without being seen as negative.

// prompt ideas

Run a Six Thinking Hats session with me on this decision: [describe the decision — e.g. whether to launch a new Etsy product line, raise my course price, or pivot my KDP niche]. Give me one paragraph per hat (White, Red, Black, Yellow, Green, Blue) in sequence, and end with a Blue Hat summary recommendation.

I tend to get stuck in [Yellow Hat optimism / Black Hat worry] when evaluating new creative ideas. Help me work through this idea — [describe your product or business idea] — by giving the underrepresented hats the most thorough treatment. I want the perspective I naturally skip.

Help me create a Six Hats thinking template I can reuse for every new [KDP niche / Etsy product category / digital product concept] I evaluate. For each hat, give me 3 specific questions tailored to a solo creator business, so I can fill it in quickly before committing time to production.
