In sum: Movements seldom win by overpowering the opposition; they win by shifting the support out from under them. Determine the social blocs at play on a given issue, and work to shift them closer to your position.
Activists are often good at analyzing systemic social problems, but less good at thinking systemically about organizing.
Activism is about using your power and voice to make change. Organizing is about that, too, but it’s also about activating and empowering others. It helps to think in terms of groups. Successful movement-building hinges on being able to see a society in terms of specific blocs or networks, some of which are institutions (unions, churches, schools), others of which are less visible or cohesive, like youth subcultures or demographic groupings.
Analyzing your spectrum of allies can help you to identify and mobilize the networks around you. A spectrum-of-allies analysis can be used to map out a local campaign or to strategize for a whole social movement.
Here’s how a spectrum-of-allies analysis works: in each wedge you can place different individuals (be specific: name them!), groups, or institutions. Moving from left to right, identify your active allies: people who agree with you and are fighting alongside you; your passive allies: folks who agree with you but aren’t doing anything about it; neutrals: fence-sitters, the unengaged; passive opposition: people who disagree with you but aren’t trying to stop you; and finally your active opposition.
