Six Thinking Hats

One-Sentence Definition

Six different colored hats represent six modes of thinking, enabling parallel thinking within a team.

Core Concept

The white hat represents objective data, the red hat represents intuition and emotions, the black hat represents risk and criticism, the yellow hat represents optimism and positivity, the green hat represents creative solutions, and the blue hat represents summary and management.

What Problem Does It Solve

When information is incomplete, options are numerous, or risks are unclear, it helps pull your judgment from intuition back to structured analysis.

More specifically, Six Thinking Hats is suitable for answering questions such as: How can I better understand the current situation? How can I make more reasonable judgments and take action?

When to Use

• When problems become complex and intuitive judgment is no longer reliable.
• When the team has disagreements about the next steps and needs a shared analytical framework.
• When you need to translate abstract judgments into concrete actions, checklists, or experiments.
• When current practices are losing effectiveness and the underlying logic needs to be re-examined.

When Not to Use

• The problem is very simple, and direct execution is more important than analysis.
• Basic facts are lacking, and you are merely spinning concepts in the air.
• The model is used only to justify existing conclusions, rather than to help refine judgment.

Summary

Six Thinking Hats allows team members to think from the same perspective at the same time, avoiding mental confusion and arguments. Proposed by Edward de Bono.
