Key to thought categorisation tokens I use. These are loosely based on the Six thinking Hats schema invented by Edward de Bono in the 1980's. It takes practice to be able to take hats off and put another on at will, but it's worth the effort.

^I ("white hat") The gathering and quality assurance of information.

^B ("black hat") Negative logic. Devil's advocate. Cost and threat analyses. Includes formal or preconceived logic on the grounds that his reduces opportunities and needs to be consciously checked at some stage using non-black thinking processes..

^P ("yellow hat") Positive logic - profit and benefit analyses.

^E ("red hat") Emotions.

^C ("green hat") The generation of ideas. Also the challenging of over-obvious assumptions and the design and execution of artifical thinking processes such as deliberately forging an unnatural association between an event and an emotion.

^M ("blue hat") The management of thinking processes such as questioning whether a sufficient thinking from all the other five categories has taken place and initiating extension processes accordingly.
