Any two or more people sharing even the thinnest common interest are by definition conspirators to some extent. Any time two people interact you have all the necessary raw materials for a conspiracy to be hatched. All that is needed is agreement toward a common end. This perspective quickly deflates the mysterious and fearful image we have of conspirators. We have seen the enemy and he is us.
Conspiracy is to commonplace that it is really quite mundane.
We recognize that man must breathe to survive. But as social creatures, men must also breathe together too survive. Husbands and wives, families, roommates, sports teams and business partners all conspire together to achieve common goals every day. Most of us are probably involved with a dozen or more conspiracies at the same time. Distinguishing between them is critical if we are to properly analyze the actions and intentions of everything from grammar school social cliques and inner city youth gangs to political parties, religious groups and multi-national corporations.
