Unconscious thought theory
Unconscious thought theory (UTT) posits that the unconscious mind is capable of performing tasks outside of one's awareness, and that unconscious thought (UT) is better at solving complex tasks, where many variables are considered, than conscious thought (CT), but is outperformed by conscious thought in tasks with fewer variables. It was proposed by Ap Dijksterhuis and Loran Nordgren in 2006.
