Tossing an idea around Can we do anything to increase creativity? There are training courses, and books, as well as “brainstorming sessions” which are supposed to do this. Taking the brainstorming sessions first, while they were very fashionable at one time, they have generally been found to be not much good when formally done, when a brainstorming session is carefully scheduled.
