Six Thinking Hats was written by Dr. Edward de Bono. "Six Thinking Hats" and the associated idea parallel thinking provide a means for groups to plan thinking processes in a detailed and cohesive way, and in doing so to think together more effectively.In 2005, the tool found some use in the United Kingdom innovation sector, where it was offered by some facilitation companies and had been trialled within the United Kingdom's civil service.

The premise of the method is that the human brain thinks in a number of distinct ways which can be deliberately challenged, and hence planned for use in a structured way allowing one to develop tactics for thinking about particular issues. De Bono identifies six distinct directions in which the brain can be challenged. In each of these directions the brain will identify and bring into conscious thought certain aspects of issues being considered (e.g. gut instinct, pessimistic judgement, neutral facts). None of these directions is a completely natural way of thinking, but rather how some of us already represent the results of our thinking.Since the hats do not represent natural modes of thinking, each hat must be used for a limited time only. Also, some will feel that using the hats is unnatural, uncomfortable or even counterproductive and against their better judgement.

A compelling example presented is sensitivity to "mismatch" stimuli.
