Six Thinking Hats – A Key That Unlocks Lateral Thinking
Brainstorming is an idea-generation technique that many GiLE readers may be familiar with. It can help foster team or individual creativity – but to get the best results, structure is needed, too. This is where de Bono’s “Six Thinking Hats” approach may come in handy.
Can meetings at work or group discussions in a communicative classroom be efficient and still take all viewpoints into account?
Alternatively, can reflective individuals be sure to consider questions from a range of angles?
Today I will suggest that the answer to both questions is “Yes”. Moreover, I believe that the “Six Thinking Hats” approach of Edward de Bono (1985) is still a valid means to such an end.

Six Thinking Hats: the basic method
This extraordinary tool was invented by the Maltese psychologist, author and consultant Edward de Bono, who died on 9th June this year. The basic idea is that any idea under consideration needs to be approached from six distinct angles, each represented by a coloured hat:
In a nutshell:
- – The blue hat runs the meeting. They want the team to succeed.
- – The other hats take turns to speak – and each gets to have his/her say.
- – No personalities are involved – this is role play, not to be taken personally.
Advocates and detractors
De Bono was a strong advocate of what he termed “lateral thinking”. His “Six Thinking Hats” invites parallel consideration of issues from different perspectives. For quite a while, the approach enjoyed considerable commercial success amongst companies who liked what they saw as its pragmatism and so bought into it. Several big companies reported that management meetings had become much more efficient once they had tried out the concept.
De Bono was not without his critics, though. Six Thinking Hats may be compatible with brainstorming, but as a tool it cannot set the agenda. In terms of outcomes, some academics demanded proof that it was this approach itself – rather than something else – that delivered the results claimed for it. Finally, De Bono’s disdain for “the tyranny of logic” irked many who still saw an important role for Socratic questioning and adversarial debate in decision-making. The Six Hats may get to have their say, but then what? From their perspective, critical thinking and the testing of propositions still seemed to be needed.

Groups of six might implement the method as follows: Individuals can also approach problems this way. They can work through the hats, one at a time, taking notes as they proceed. If you do this, you should only wear one hat at a time, and avoid jumping from one hat to another. This maintains focus and avoids any one hat being unduly influenced by another hat. Here in 2021, I would like to suggest that Six Thinking Hats is still a useful tool. Moreover, several top companies appear to agree – as https://www.edwddebono.com/six-thinking-hats is only too proud to point out. I would not agree with de Bono’s rather extraordinary suggestion that the idea at a stroke overthrew the legacy of Socrates, Plato, and Aristotle. However, I do think that it may enable workplace teams, groups of students working together and individuals to consider issues from multiple perspectives in a structured way. It can facilitate better teamwork as well as better critical reflection on the part of individuals who may wish to wear and switch metaphorical hats when testing out their own ideas. In my view, Six Thinking Hats is conducive to divergent thinking and creativity. In good hands, it has the potential to generate more ideas – and those who have more sensible ideas are more likely to identify the best ideas of all. Whether or not one adopts de Bono’s exact approach, these are things worth striving for. Bibliography De Bono, E. 1985. Six thinking hats. Toronto, Ont: Key Porter Books. Harvard (18th ed.).
