group has a culture that establishes norms of behavior; has a ‘personality’ (persona) that reflects the collective conscious and unconscious disposition of its members (e.g. a fun group); and has a shadow side (often the opposite of its revealed persona).
• Controlling a group is almost impossible.
• Contrary to what many would like to believe or pretend.
• If the group is an integrated system, no single component can control the rest.
• One component, however, can have an impact on the whole system.
