Groups: 10 Rules That Govern Groups

What most groups of people have in common.

Much of our lives are spent in groups with other people: we form groups to socialise, earn money, play sport, make music, even to change the world. But although groups are diverse, many of the psychological processes involved are remarkably similar.

Here are 10 insightful studies that give a flavour of what has been discovered about the dynamics of group psychology.

'Quadrophenia' is a 1979 British film, loosely based around the 1973 rock opera of the same name by The Who. The film stars Phil Daniels as a Mod named Jimmy and makes a good example how 'teens' form groups to define their identity. The film, set in 1965, follows the story of Jimmy Cooper (Phil Daniels), a London Mod. Disillusioned by his parents and a job as a post room boy in an advertising firm, Jimmy finds an outlet for his teenage angst with his Mod friends Dave (Mark Wingett), Chalky (Philip Davis) and Spider (Gary Shail). However, his angst and confusion are compounded by the fact that one of the Mods' rivals, the Rockers, is in fact childhood friend Kevin (Ray Winstone). An assault by aggressive Rockers on Spider leads to a serious unprovoked attack on a Rocker who, unbeknownst to Jimmy and his Mod mates, is Kevin.
