Good thinking is simple. The goal of effective thinking is to make complexity managable. The Six Thinking Hats Method is by design a KISS system that is not intended to emphasize how clever any individuals in a group are, but to make actionable decisions--in most cases to achieve business results (as de Bono wryly notes elsewhere, most academics aren't interested in effective thinking).
The reason I'm writing this review is to correct an inaccuracy in the previous review. Having each person in a group adopt a different hat is exactly the OPPOSITE of what is intended with the Parallel Thinking method (a virtual synonym for the Six Hat method). The idea is that everyone in a group focusses on a specific element (Hat) at the same time, not individually. Doing it this way reduces argument and the role of ego in the conversation.
As de Bono notes, an important element in his work is also to demystify creativity, and help people understand you don't need lava lamps and candles to "do" creativity effectively. You don't have to be goofy. Ordinary business people working on engines and vaccines--and, as far as that goes, Accounts Payable, Sales, and Project Management--need creativity to be effective and competitive in a 24 hour global marketplace.
