An anonymous reader writes to mention that a recent University of Minnesota study suggests that ceiling height may affect problem-solving skills. "'When people are in a room with a high ceiling, they activate the idea of freedom. In a low-ceilinged room, they activate more constrained, confined concepts.' Either can be good. The concept of freedom promotes information processing that encourages greater variation in the kinds of thoughts one has, said Meyers-Levy, professor of marketing at the University of Minnesota. The concept of confinement promotes more detail-oriented processing."
