A research study from the University of Minnesota suggests that the way people think and act is affected by ceiling height. According to the authors, "When a person is in a space with a 10-foot ceiling, they will tend to think more freely, more abstractly. They might process more abstract connections between objects in a room, whereas a person in a room with an 8-foot ceiling will be more likely to focus on specifics." (UNM News via Lifehacker.)
Ombuds may then want to consider rooms with high ceilings when facilitating discussions for creative resolutions.
