Edward de Bono: The man who tried to teach the world how to think

Ideas & Philosophy · Published 30 September 2026 Swipe more like this →

In short: A Rhodes Scholar and physician, Edward de Bono became a global authority on creativity by championing lateral thinking. He authored 85 books, advised governments, and proposed radical solutions for geopolitical conflicts—including shipping Marmite to resolve regional tensions. Yet, his pragmatic approach to the mind remains a subject of intense academic debate.

Born in Malta in 1933, Edward de Bono built a career that spanned medicine, psychology, and philosophy. After earning a medical degree from the University of Malta and a PhD from Cambridge, he held faculty appointments at prestigious institutions including Oxford, Harvard, and London. He is best known for coining the term 'lateral thinking' in his 1967 book, The Use of Lateral Thinking, which The Sunday Times later named one of the 12 most influential books published since World War II.

De Bono’s work often challenged traditional Western logic, which he dubbed the 'Greek gang of three'—Socrates, Plato, and Aristotle. He advocated for 'parallel thinking,' a method designed to replace adversarial debate with constructive exploration. His most famous implementation, the Six Thinking Hats, encourages groups to view problems from multiple, non-conflicting perspectives. Beyond corporate seminars, he applied his 'Thinking Tools' to global policy, even suggesting in 2000 that the Arab–Israeli conflict might be mitigated by addressing zinc deficiencies in populations consuming unleavened bread.

Despite his immense commercial success, de Bono faced criticism from the academic community. In the Handbook of Creativity, Robert J. Sternberg noted that de Bono’s pragmatic focus on developing creativity often bypassed rigorous scientific validation. A 2006 evaluation of 42 thinking frameworks, Frameworks For Thinking, found sparse evidence that his tools produced generalized improvements in thinking performance. Similarly, management professor M. Afzalur Rahim criticized de Bono’s 1985 work on conflict resolution as being 'out of tune with modern thinking.'

Beyond his intellectual pursuits, de Bono was a man of eccentric interests. He was an avid collector of private islands, owning four across the Bahamas, Ireland, Italy, and Australia, viewing them as personal principalities. He also proposed a numerical language to clarify human communication and even suggested that companies could issue their own private currencies. Whether viewed as a visionary or a purveyor of unproven methods, his influence on how we approach problem-solving remains a significant, if contested, part of the modern intellectual landscape.
