Edward De Bono's 6 Thinking Hats..... (Edited excerpt)
https://en.wikipedia.org/wiki/Six_Thinking_Hats
Six Thinking Hats is a system designed by Edward de Bono which is described as a tool for group discussion or individual thinking by using "Six Thinking Hats" It is used to plan thinking processes in a detailed, cohesive and an effective way. The premise of the method is that the human brain thinks in a number of distinct ways which can be deliberately challenged. De Bono identifies six distinct directions in which the brain can be challenged. Since the hats do not represent natural modes of thinking, each hat must be used for a limited time only. Also, many will feel that using the hats is unnatural, uncomfortable or even counterproductive and against their better judgement.
Six distinct directions are identified and assigned a color. The six directions are:
Managing Blue - what is the subject? what are we thinking about? what is the goal? Can look at the big picture.
Information White - considering purely what information is available, what are the facts?
Emotions Red - intuitive or instinctive gut reactions or statements of emotional feeling (but not any justification)
Discernment Black - logic applied to identifying reasons to be cautious and conservative. Practical, realistic.
Optimistic response Yellow - logic applied to identifying benefits, seeking harmony. Sees the brighter, sunny side of situations.
Creativity Green - statements of provocation and investigation, seeing where a thought goes. Thinks creatively, out of the box.
Coloured hats are used as metaphors for each direction. So when an idea is discussed, all participants must 'wear' only the hat being discussed.... This roots out negativity or criticism, as flaws or fallacies can be discussed when wearing a black hat....
