There are as many of these "mind tools" out there as there are kinds of chewing gum. No use to blame Edward de Bono, it's always been with us in various forms: Descartes, Buddhist meditation, Euclid, the structure of language, etc. These post-de Bono tools however are just the latest fads to come along - stealing a bit from psychology to give it a dash of science, tossing a bit of I-Ching-ish operational mumbo jumbo to distract us from seeing the parts that don't add up.
In this age of Mind Tool-ism there needs to be a way to simplify this vast array of choices: a meta-mind tool that unifies all of the above into a single system: All-in-one Mind-Blowing Toolbox (TM, pat. pending, registered, copyright 2009 by David Tse).
For some reason I am reminded of a short story by Kurt V. called "Report on the Barnhouse Effect"; maybe because it parodies this cult of mind tool-ism. Actually, it may not - but it's a damn good read regardless!
