The term Six Thinking Hats is also used to describe the tool for group discussion and individual thinking that is the subject of the book by Edward De Bono. It is used for Lateral thinking. Each hat has a different meaning and uses.
White – Refers to the pure facts of the subject matter.
Red – The emotional response or gut feeling that we experience when we experience the subject matter
Black – Black is about problems or flaws in the subject matter.
Yellow – yellow is about positives of it (uniformity about it, consistency, calming etc)
Green – Statements of provocation and investigation, seeing where a thought goes. The Open. (Things that has a function, add a layer of complexity to the work)
I have to admit that at first I thought the thinking hats were balderdash, but then I realised the importance of it in assessing the work of others and more importantly myself.
