· Research shows group members equate creativity with conformity. Creativity is a much coveted asset for a very simple reason: an idea that transcends orthodoxy has the power to bring wealth, fame and status. Commercial, scientific, educational and artistic organisations, therefore, often talk about how they want to foster creativity. Unfortunately groups only rarely foment great ideas because people in them are powerfully shaped by group norms: the unwritten rules which describe how individuals in a group 'are' and how they 'ought' to behave. Norms influence what people believe is right and wrong just as surely as real laws, but with none of the permanence or transparency of written regulations.
