Bikeshedding, or the Law of Triviality, is the tendency for groups to spend disproportionate time on trivial issues while neglecting complex but more important ones. Coined by C. Northcote Parkinson in 1957, it arises because everyone can contribute an opinion on simple matters while complex matters are beyond most participants' ability to evaluate.
Six Thinking Hats is a parallel thinking framework developed by Edward de Bono that separates six distinct modes of thought β facts, emotions, caution, optimism, creativity, and process β and assigns each a coloured hat. By having all participants adopt the same thinking mode simultaneously, teams eliminate debate-style conflict and explore problems more completely. Used by IBM, NASA, and Merck to improve decision quality and meeting efficiency.
